- Mutt-ng offers great flexibility due to the use of functions: internally, every
- action a user can make mutt-ng perform is named ``function.'' Those functions
+Chapter 2. Getting Started

+ Table of Contents
- are assigned to keys (or even key sequences) and may be completely adjusted to
- user's needs. The basic idea is that the impatient users get a very intuitive
- interface to start off with and advanced users virtually get no limits to
- adjustments.

- Mutt-ng has two basic concepts of user interaction:
+ 2. Screens and Menus
- 1. There is one dedicated line on the screen used to query the user for
- input, issue any command, query variables and display error and informa-
- tional messages. As for every type of user input, this requires manual
- action leading to the need of input.

+ 2.9. Key Menu
- 2. The automatized interface for interaction are the so called _\bh_\bo_\bo_\bk_\bs. Hooks
- specify actions the user wants to be performed at well-defined situa-
- tions: what to do when entering which folder, what to do when displaying
- or replying to what kind of message, etc. These are optional, i.e. a user
- doesn't need to specify them but can do so.

+ 5.1. The Message Index
+ 5.2. The Pager
+ 5.3. Threaded Mode
+ 5.4. Miscellaneous Functions
- Although mutt-ng has many functionality built-in, many features can be dele-
- gated to external tools to increase flexibility: users can define programs to
- filter a message through before displaying, users can use any program they want
- for displaying a message, message types (such as PDF or PostScript) for which
- mutt-ng doesn't have a built-in filter can be rendered by arbitrary tools and
- so forth. Although mutt-ng has an alias mechanism built-in, it features using
- external tools to query for nearly every type of addresses from sources like
- LDAP, databases or just the list of locally known users.

- _\b2_\b._\b2_\b._\b1 _\bI_\bn_\bd_\be_\bx
+1.1. Screens and Menus
- The index is the screen that you usually see first when you start mutt-ng. It
- gives an overview over your emails in the currently opened mailbox. By default,
- this is your system mailbox. The information you see in the index is a list of
+ mutt-ng offers different screens of which every has its special purpose:
+ * The index displays the contents of the currently opened mailbox.
+ * The pager is responsible for displaying messages, that is, the header, the body and all attached parts.
+ * The file browser offers operations on and displays information of all folders mutt-ng should watch for mail.
+ * The sidebar offers a permanent view of which mailboxes contain how many total, new and/or flagged mails.
+ * The help screen lists for all currently available commands how to invoke them as well as a short description.
+ * The compose menu is a comfortable interface take last actions before sending mail: change subjects, attach files, remove attachements, etc.
+ * The attachement menu gives a summary and the tree structure of the attachements of the current message.
+ * The alias menu lists all or a fraction of the aliases a user has defined.
+ * The key menu used in connection with encryption lets users choose the right key to encrypt with.
- The Mutt Next Generation E-Mail Client 5
+ When mutt-ng is started without any further options, it'll open the users default mailbox and display the index.
- emails, each with its number on the left, its flags (new email, important
- email, email that has been forwarded or replied to, tagged email, ...), the
- date when email was sent, its sender, the email size, and the subject. Addi-
- tionally, the index also shows thread hierarchies: when you reply to an email,
- and the other person replies back, you can see the other's person email in a
- "sub-tree" below. This is especially useful for personal email between a group
- of people or when you've subscribed to mailing lists.
+1.2. Configuration
- _\b2_\b._\b2_\b._\b2 _\bP_\ba_\bg_\be_\br
+ Mutt-ng does not feature an internal configuration interface or menu due to the simple fact that this would be too complex to handle (currently there are several hundred variables which fine-tune the behaviour.)
- The pager is responsible for showing the email content. On the top of the pager
- you have an overview over the most important email headers like the sender, the
- recipient, the subject, and much more information. How much information you
- actually see depends on your configuration, which we'll describe below.
+ Mutt-ng is configured using configuration files which allow users to add comments or manage them via version control systems to ease maintenance.
- Below the headers, you see the email body which usually contains the message.
- If the email contains any attachments, you will see more information about them
- below the email body, or, if the attachments are text files, you can view them
- directly in the pager.
+ Also, mutt-ng comes with a shell script named grml-muttng kindly contributed by users which really helps and eases the creation of a user's configuration file. When downloading the source code via a snapshot or via subversion, it can be found in the contrib directory.
- To give the user a good overview, it is possible to configure mutt-ng to show
- different things in the pager with different colors. Virtually everything that
- can be described with a regular expression can be colored, e.g. URLs, email
- addresses or smileys.
+1.3. Functions
- _\b2_\b._\b2_\b._\b3 _\bF_\bi_\bl_\be _\bB_\br_\bo_\bw_\bs_\be_\br
+ Mutt-ng offers great flexibility due to the use of functions: internally, every action a user can make mutt-ng perform is named ``function.'' Those functions are assigned to keys (or even key sequences) and may be completely adjusted to user's needs. The basic idea is that the impatient users get a very intuitive interface to start off with and advanced users virtually get no limits to adjustments.
- The file browser is the interface to the local or remote file system. When
- selecting a mailbox to open, the browser allows custom sorting of items, limit-
- ing the items shown by a regular expression and a freely adjustable format of
- what to display in which way. It also allows for easy navigation through the
- file system when selecting file(s) to attach to a message, select multiple
- files to attach and many more.
-
- _\b2_\b._\b2_\b._\b4 _\bS_\bi_\bd_\be_\bb_\ba_\br
-
- The sidebar comes in handy to manage mails which are spread over different
- folders. All folders users setup mutt-ng to watch for new mail will be listed.
- The listing includes not only the name but also the number of total messages,
- the number of new and flagged messages. Items with new mail may be colored dif-
- ferent from those with flagged mail, items may be shortened or compress if
- they're they to long to be printed in full form so that by abbreviated names,
- user still now what the name stands for.
+1.4. Interaction
- _\b2_\b._\b2_\b._\b5 _\bH_\be_\bl_\bp
+ Mutt-ng has two basic concepts of user interaction:
+ 1. There is one dedicated line on the screen used to query the user for input, issue any command, query variables and display error and informational messages. As for every type of user input, this requires manual action leading to the need of input.
+ 2. The automatized interface for interaction are the so called hooks. Hooks specify actions the user wants to be performed at well-defined situations: what to do when entering which folder, what to do when displaying or replying to what kind of message, etc. These are optional, i.e. a user doesn't need to specify them but can do so.
- The Mutt Next Generation E-Mail Client 6
+1.5. Modularization
- The help screen is meant to offer a quick help to the user. It lists the cur-
- rent configuration of key bindings and their associated commands including a
- short description, and currently unbound functions that still need to be asso-
- ciated with a key binding (or alternatively, they can be called via the mutt-ng
- command prompt).
-
- _\b2_\b._\b2_\b._\b6 _\bC_\bo_\bm_\bp_\bo_\bs_\be _\bM_\be_\bn_\bu
-
- The compose menu features a split screen containing the information which
- really matter before actually sending a message by mail or posting an article
- to a newsgroup: who gets the message as what (recipient, newsgroup, who gets
- what kind of copy). Additionally, users may set security options like deciding
- whether to sign, encrypt or sign and encrypt a message with/for what keys.
-
- Also, it's used to attach messages, news articles or files to a message, to re-
- edit any attachment including the message itself.
-
- _\b2_\b._\b2_\b._\b7 _\bA_\bl_\bi_\ba_\bs _\bM_\be_\bn_\bu
-
- The alias menu is used to help users finding the recipients of messages. For
- users who need to contact many people, there's no need to remember addresses or
- names completely because it allows for searching, too. The alias mechanism and
- thus the alias menu also features grouping several addresses by a shorter nick-
- name, the actual alias, so that users don't have to select each single recipi-
- ent manually.
-
- _\b2_\b._\b2_\b._\b8 _\bA_\bt_\bt_\ba_\bc_\bh_\bm_\be_\bn_\bt _\bM_\be_\bn_\bu
-
- As will be later discussed in detail, mutt-ng features a good and stable MIME
- implementation, that is, is greatly supports sending and receiving messages of
- arbitrary type. The attachment menu displays a message's structure in detail:
- what content parts are attached to which parent part (which gives a true tree
- structure), which type is of what type and what size. Single parts may saved,
- deleted or modified to offer great and easy access to message's internals.

- textual data such as email addresses or filenames. The keys used to move
- around while editing are very similar to those of Emacs.
-
- ^A or <Home> bol move to the start of the line
- ^B or <Left> backward-char move back one char
- Esc B backward-word move back one word
- ^D or <Delete> delete-char delete the char under the cursor
- ^E or <End> eol move to the end of the line
- ^F or <Right> forward-char move forward one char
- Esc F forward-word move forward one word
- <Tab> complete complete filename or alias
- ^T complete-query complete address with query
- ^K kill-eol delete to the end of the line
- ESC d kill-eow delete to the end of the word
- ^W kill-word kill the word in front of the cursor
- ^U kill-line delete entire line
- ^V quote-char quote the next typed key
- <Up> history-up recall previous string from history
- <Down> history-down recall next string from history
- <BackSpace> backspace kill the char in front of the cursor
- Esc u upcase-word convert word to upper case
- Esc l downcase-word convert word to lower case
- Esc c capitalize-word capitalize the word
- ^G n/a abort
- <Return> n/a finish editing
-
- You can remap the _\be_\bd_\bi_\bt_\bo_\br functions using the _\bb_\bi_\bn_\bd (section 3.5 , page 26) com-
- mand. For example, to make the _\bD_\be_\bl_\be_\bt_\be key delete the character in front of the
- cursor rather than under, you could use
-
- bind editor <delete> backspace

- The Mutt Next Generation E-Mail Client 8
+ Although mutt-ng has many functionality built-in, many features can be delegated to external tools to increase flexibility: users can define programs to filter a message through before displaying, users can use any program they want for displaying a message, message types (such as PDF or PostScript) for which mutt-ng doesn't have a built-in filter can be rendered by arbitrary tools and so forth. Although mutt-ng has an alias mechanism built-in, it features using external tools to query for nearly every type of addresses from sources like LDAP, databases or just the list of locally known users.

+1.6. Patterns
- Similar to many other mail clients, there are two modes in which mail is read
- in Mutt-ng. The first is the index of messages in the mailbox, which is called
- the ``index'' in Mutt-ng. The second mode is the display of the message con-
- tents. This is called the ``pager.''
+ Mutt-ng has a built-in pattern matching ``language'' which is as widely used as possible to present a consistent interface to users. The same ``pattern terms'' can be used for searching, scoring, message selection and much more.
- The next few sections describe the functions provided in each of these modes.

-
- In addition to who sent the message and the subject, a short summary of the
- disposition of each message is printed beside the message number. Zero or more
- of the following ``flags'' may appear, which mean:
-
- D
- message is deleted (is marked for deletion)
-
- d
- message have attachments marked for deletion
-
- The Mutt Next Generation E-Mail Client 9
-
- K
- contains a PGP public key
-
- N
- message is new
-
- O
- message is old
-
- P
- message is PGP encrypted
-
- r
- message has been replied to
-
- S
- message is signed, and the signature is succesfully verified
-
- s
- message is signed
-
- !
- message is flagged
-
- *
- message is tagged
-
- Some of the status flags can be turned on or off using
-
- +\bo s\bse\bet\bt-\b-f\bfl\bla\bag\bg (default: w)
-
- +\bo c\bcl\ble\bea\bar\br-\b-f\bfl\bla\bag\bg (default: W)
-
- Furthermore, the following flags reflect who the message is addressed to. They
- can be customized with the _\b$_\bt_\bo_\b__\bc_\bh_\ba_\br_\bs (section 7.4.330 , page 170) variable.
-
- +
- message is to you and you only
-
- T
- message is to you, but also to or cc'ed to others
-
- C
- message is cc'ed to you
-
- F
- message is from you
-
- L
- message is sent to a subscribed mailing list
-
- _\b2_\b._\b5_\b._\b2 _\bT_\bh_\be _\bP_\ba_\bg_\be_\br
-
- By default, Mutt-ng uses its builtin pager to display the body of messages.
-
- The Mutt Next Generation E-Mail Client 10
-
- The pager is very similar to the Unix program _\bl_\be_\bs_\bs though not nearly as fea-
- tureful.
-
- <Return> go down one line
- <Space> display the next page (or next message if at the end of a message)
- - go back to the previous page
- n search for next match
- S skip beyond quoted text
- T toggle display of quoted text
- ? show key bindings
- / search for a regular expression (pattern)
- ESC / search backwards for a regular expression
- \ toggle search pattern coloring
- ^ jump to the top of the message
-
- In addition, many of the functions from the _\bi_\bn_\bd_\be_\bx are available in the pager,
- such as _\bd_\be_\bl_\be_\bt_\be_\b-_\bm_\be_\bs_\bs_\ba_\bg_\be or _\bc_\bo_\bp_\by_\b-_\bm_\be_\bs_\bs_\ba_\bg_\be (this is one advantage over using an
- external pager to view messages).
+ The index is the screen that you usually see first when you start mutt-ng. It gives an overview over your emails in the currently opened mailbox. By default, this is your system mailbox. The information you see in the index is a list of emails, each with its number on the left, its flags (new email, important email, email that has been forwarded or replied to, tagged email, ...), the date when email was sent, its sender, the email size, and the subject. Additionally, the index also shows thread hierarchies: when you reply to an email, and the other person replies back, you can see the other's person email in a "sub-tree" below. This is especially useful for personal email between a group of people or when you've subscribed to mailing lists.
- Also, the internal pager supports a couple other advanced features. For one, it
- will accept and translate the ``standard'' nroff sequences for bold and under-
- line. These sequences are a series of either the letter, backspace (^H), the
- letter again for bold or the letter, backspace, ``_'' for denoting underline.
- Mutt-ng will attempt to display these in bold and underline respectively if
- your terminal supports them. If not, you can use the bold and underline _\bc_\bo_\bl_\bo_\br
- (section 3.9 , page 30) objects to specify a color or mono attribute for them.
+2.2. Pager
- Additionally, the internal pager supports the ANSI escape sequences for charac-
- ter attributes. Mutt-ng translates them into the correct color and character
- settings. The sequences Mutt-ng supports are:
+ The pager is responsible for showing the email content. On the top of the pager you have an overview over the most important email headers like the sender, the recipient, the subject, and much more information. How much information you actually see depends on your configuration, which we'll describe below.
- ESC [ Ps;Ps;Ps;...;Ps m
- where Ps =
- 0 All Attributes Off
- 1 Bold on
- 4 Underline on
- 5 Blink on
- 7 Reverse video on
- 3x Foreground color is x
- 4x Background color is x
+ Below the headers, you see the email body which usually contains the message. If the email contains any attachments, you will see more information about them below the email body, or, if the attachments are text files, you can view them directly in the pager.
- Colors are
- 0 black
- 1 red
- 2 green
- 3 yellow
- 4 blue
- 5 magenta
- 6 cyan
- 7 white
+ To give the user a good overview, it is possible to configure mutt-ng to show different things in the pager with different colors. Virtually everything that can be described with a regular expression can be colored, e.g. URLs, email addresses or smileys.
- The Mutt Next Generation E-Mail Client 11
+2.3. File Browser
- Mutt-ng uses these attributes for handling text/enriched messages, and they can
- also be used by an external _\ba_\bu_\bt_\bo_\bv_\bi_\be_\bw (section 5.4 , page 78) script for high-
- lighting purposes. N\bNo\bot\bte\be:\b: If you change the colors for your display, for exam-
- ple by changing the color associated with color2 for your xterm, then that
- color will be used instead of green.
+ The file browser is the interface to the local or remote file system. When selecting a mailbox to open, the browser allows custom sorting of items, limiting the items shown by a regular expression and a freely adjustable format of what to display in which way. It also allows for easy navigation through the file system when selecting file(s) to attach to a message, select multiple files to attach and many more.
- _\b2_\b._\b5_\b._\b3 _\bT_\bh_\br_\be_\ba_\bd_\be_\bd _\bM_\bo_\bd_\be
+2.4. Sidebar
- When the mailbox is _\bs_\bo_\br_\bt_\be_\bd (section 7.4.298 , page 160) by _\bt_\bh_\br_\be_\ba_\bd_\bs, there are
- a few additional functions available in the _\bi_\bn_\bd_\be_\bx and _\bp_\ba_\bg_\be_\br modes.
+ The sidebar comes in handy to manage mails which are spread over different folders. All folders users setup mutt-ng to watch for new mail will be listed. The listing includes not only the name but also the number of total messages, the number of new and flagged messages. Items with new mail may be colored different from those with flagged mail, items may be shortened or compress if they're they to long to be printed in full form so that by abbreviated names, user still now what the name stands for.
- ^D delete-thread delete all messages in the current thread
- ^U undelete-thread undelete all messages in the current thread
- ^N next-thread jump to the start of the next thread
- ^P previous-thread jump to the start of the previous thread
- ^R read-thread mark the current thread as read
- ESC d delete-subthread delete all messages in the current subthread
- ESC u undelete-subthread undelete all messages in the current subthread
- ESC n next-subthread jump to the start of the next subthread
- ESC p previous-subthread jump to the start of the previous subthread
- ESC r read-subthread mark the current subthread as read
- ESC t tag-thread toggle the tag on the current thread
- ESC v collapse-thread toggle collapse for the current thread
- ESC V collapse-all toggle collapse for all threads
- P parent-message jump to parent message in thread
-
- N\bNo\bot\bte\be:\b: Collapsing a thread displays only the first message in the thread and
- hides the others. This is useful when threads contain so many messages that you
- can only see a handful of threads on the screen. See %M in _\b$_\bi_\bn_\bd_\be_\bx_\b__\bf_\bo_\br_\bm_\ba_\bt (sec-
- tion 7.4.116 , page 115). For example, you could use "%?M?(#%03M)&(%4l)?" in
- _\b$_\bi_\bn_\bd_\be_\bx_\b__\bf_\bo_\br_\bm_\ba_\bt (section 7.4.116 , page 115) to optionally display the number of
- hidden messages if the thread is collapsed.
-
- See also: _\b$_\bs_\bt_\br_\bi_\bc_\bt_\b__\bt_\bh_\br_\be_\ba_\bd_\bs (section 7.4.319 , page 167).
-
- _\b2_\b._\b5_\b._\b4 _\bM_\bi_\bs_\bc_\be_\bl_\bl_\ba_\bn_\be_\bo_\bu_\bs _\bF_\bu_\bn_\bc_\bt_\bi_\bo_\bn_\bs
-
- c\bcr\bre\bea\bat\bte\be-\b-a\bal\bli\bia\bas\bs
- (default: a)
-
- Creates a new alias based upon the current message (or prompts for a new one).
- Once editing is complete, an _\ba_\bl_\bi_\ba_\bs (section 3.4 , page 25) command is added to
- the file specified by the _\b$_\ba_\bl_\bi_\ba_\bs_\b__\bf_\bi_\bl_\be (section 7.4.5 , page 89) variable for
- future use. N\bNo\bot\bte\be:\b: Specifying an _\b$_\ba_\bl_\bi_\ba_\bs_\b__\bf_\bi_\bl_\be (section 7.4.5 , page 89) does not
- add the aliases specified there-in, you must also _\bs_\bo_\bu_\br_\bc_\be (section 3.29 , page
- 45) the file.
-
- c\bch\bhe\bec\bck\bk-\b-t\btr\bra\bad\bdi\bit\bti\bio\bon\bna\bal\bl-\b-p\bpg\bgp\bp
- (default: ESC P)
-
- This function will search the current message for content signed or encrypted
- with PGP the "traditional" way, that is, without proper MIME tagging.
-
- The Mutt Next Generation E-Mail Client 12
-
- Technically, this function will temporarily change the MIME content types of
- the body parts containing PGP data; this is similar to the _\be_\bd_\bi_\bt_\b-_\bt_\by_\bp_\be (section
- 2.5.4 , page 12) function's effect.
-
- d\bdi\bis\bsp\bpl\bla\bay\by-\b-t\bto\bog\bgg\bgl\ble\be-\b-w\bwe\bee\bed\bd
- (default: h)
-
- Toggles the weeding of message header fields specified by _\bi_\bg_\bn_\bo_\br_\be (section
- 3.10 , page 32) commands.
-
- e\bed\bdi\bit\bt
- (default: e)
-
- This command (available in the ``index'' and ``pager'') allows you to edit the
- raw current message as it's present in the mail folder. After you have fin-
- ished editing, the changed message will be appended to the current folder, and
- the original message will be marked for deletion.
-
- e\bed\bdi\bit\bt-\b-t\bty\byp\bpe\be
-
- (default: ^E on the attachment menu, and in the pager and index menus; ^T on
- the compose menu)
-
- This command is used to temporarily edit an attachment's content type to fix,
- for instance, bogus character set parameters. When invoked from the index or
- from the pager, you'll have the opportunity to edit the top-level attachment's
- content type. On the _\ba_\bt_\bt_\ba_\bc_\bh_\bm_\be_\bn_\bt _\bm_\be_\bn_\bu (section 5.1.2 , page 70), you can
- change any attachment's content type. These changes are not persistent, and get
- lost upon changing folders.
-
- Note that this command is also available on the _\bc_\bo_\bm_\bp_\bo_\bs_\be _\bm_\be_\bn_\bu (section 5.1.3 ,
- page 71). There, it's used to fine-tune the properties of attachments you are
- going to send.
+2.5. Help
- e\ben\bnt\bte\ber\br-\b-c\bco\bom\bmm\bma\ban\bnd\bd
- (default: ``:'')
+ The help screen is meant to offer a quick help to the user. It lists the current configuration of key bindings and their associated commands including a short description, and currently unbound functions that still need to be associated with a key binding (or alternatively, they can be called via the mutt-ng command prompt).
- This command is used to execute any command you would normally put in a config-
- uration file. A common use is to check the settings of variables, or in con-
- junction with _\bm_\ba_\bc_\br_\bo_\bs (section 3.8 , page 29) to change settings on the fly.
+2.6. Compose Menu
- e\bex\bxt\btr\bra\bac\bct\bt-\b-k\bke\bey\bys\bs
- (default: ^K)
+ The compose menu features a split screen containing the information which really matter before actually sending a message by mail or posting an article to a newsgroup: who gets the message as what (recipient, newsgroup, who gets what kind of copy). Additionally, users may set security options like deciding whether to sign, encrypt or sign and encrypt a message with/for what keys.
- This command extracts PGP public keys from the current or tagged message(s) and
- adds them to your PGP public key ring.
+ Also, it's used to attach messages, news articles or files to a message, to re-edit any attachment including the message itself.
- f\bfo\bor\brg\bge\bet\bt-\b-p\bpa\bas\bss\bsp\bph\bhr\bra\bas\bse\be
- (default: ^F)
+2.7. Alias Menu
- This command wipes the passphrase(s) from memory. It is useful, if you mis-
- spelled the passphrase.
+ The alias menu is used to help users finding the recipients of messages. For users who need to contact many people, there's no need to remember addresses or names completely because it allows for searching, too. The alias mechanism and thus the alias menu also features grouping several addresses by a shorter nickname, the actual alias, so that users don't have to select each single recipient manually.
- The Mutt Next Generation E-Mail Client 13
+2.8. Attachment Menu
- l\bli\bis\bst\bt-\b-r\bre\bep\bpl\bly\by
- (default: L)
+ As will be later discussed in detail, mutt-ng features a good and stable MIME implementation, that is, is greatly supports sending and receiving messages of arbitrary type. The attachment menu displays a message's structure in detail: what content parts are attached to which parent part (which gives a true tree structure), which type is of what type and what size. Single parts may saved, deleted or modified to offer great and easy access to message's internals.
- Reply to the current or tagged message(s) by extracting any addresses which
- match the regular expressions given by the _\bl_\bi_\bs_\bt_\bs _\bo_\br _\bs_\bu_\bb_\bs_\bc_\br_\bi_\bb_\be (section 3.13 ,
- page 35) commands, but also honor any Mail-Followup-To header(s) if the
- _\b$_\bh_\bo_\bn_\bo_\br_\b__\bf_\bo_\bl_\bl_\bo_\bw_\bu_\bp_\b__\bt_\bo (section 7.4.94 , page 110) configuration variable is set.
- Using this when replying to messages posted to mailing lists helps avoid dupli-
- cate copies being sent to the author of the message you are replying to.
+2.9. Key Menu
- p\bpi\bip\bpe\be-\b-m\bme\bes\bss\bsa\bag\bge\be
- (default: |)
+ FIXME
- Asks for an external Unix command and pipes the current or tagged message(s) to
- it. The variables _\b$_\bp_\bi_\bp_\be_\b__\bd_\be_\bc_\bo_\bd_\be (section 7.4.207 , page 139), _\b$_\bp_\bi_\bp_\be_\b__\bs_\bp_\bl_\bi_\bt
- (section 7.4.209 , page 140), _\b$_\bp_\bi_\bp_\be_\b__\bs_\be_\bp (section 7.4.208 , page 139) and
- _\b$_\bw_\ba_\bi_\bt_\b__\bk_\be_\by (section 7.4.341 , page 172) control the exact behavior of this
- function.
+3. Moving Around in Menus
- r\bre\bes\bse\ben\bnd\bd-\b-m\bme\bes\bss\bsa\bag\bge\be
- (default: ESC e)
+ Information is presented in menus, very similar to ELM. Here is a table showing the common keys used to navigate menus in Mutt-ng.
+j or Down next-entry move to the next entry
+k or Up previous-entry move to the previous entry
+z or PageDn page-down go to the next page
+Z or PageUp page-up go to the previous page
+= or Home first-entry jump to the first entry
+* or End last-entry jump to the last entry
+q quit exit the current menu
+? help list all key bindings for the current menu
- With resend-message, mutt takes the current message as a template for a new
- message. This function is best described as "recall from arbitrary folders".
- It can conveniently be used to forward MIME messages while preserving the orig-
- inal mail structure. Note that the amount of headers included here depends on
- the value of the _\b$_\bw_\be_\be_\bd (section 7.4.342 , page 172) variable.
+4. Editing Input Fields
- This function is also available from the attachment menu. You can use this to
- easily resend a message which was included with a bounce message as a mes-
- sage/rfc822 body part.
+ Mutt-ng has a builtin line editor which is used as the primary way to input textual data such as email addresses or filenames. The keys used to move around while editing are very similar to those of Emacs.
+^A or <Home> bol move to the start of the line
+^B or <Left> backward-char move back one char
+Esc B backward-word move back one word
+^D or <Delete> delete-char delete the char under the cursor
+^E or <End> eol move to the end of the line
+^F or <Right> forward-char move forward one char
+Esc F forward-word move forward one word
+<Tab> complete complete filename or alias
+^T complete-query complete address with query
+^K kill-eol delete to the end of the line
+ESC d kill-eow delete to the end of the word
+^W kill-word kill the word in front of the cursor
+^U kill-line delete entire line
+^V quote-char quote the next typed key
+<Up> history-up recall previous string from history
+<Down> history-down recall next string from history
+<BackSpace> backspace kill the char in front of the cursor
+Esc u upcase-word convert word to upper case
+Esc l downcase-word convert word to lower case
+Esc c capitalize-word capitalize the word
+^G n/a abort
+<Return> n/a finish editing
- s\bsh\bhe\bel\bll\bl-\b-e\bes\bsc\bca\bap\bpe\be
- (default: !)
+ You can remap the editor functions using the bind command. For example, to make the Delete key delete the character in front of the cursor rather than under, you could use
- Asks for an external Unix command and executes it. The _\b$_\bw_\ba_\bi_\bt_\b__\bk_\be_\by (section
- 7.4.341 , page 172) can be used to control whether Mutt-ng will wait for a key
- to be pressed when the command returns (presumably to let the user read the
- output of the command), based on the return status of the named command.
+ bind editor <delete> backspace
- t\bto\bog\bgg\bgl\ble\be-\b-q\bqu\buo\bot\bte\bed\bd
- (default: T)
+5. Reading Mail - The Index and Pager
- The _\bp_\ba_\bg_\be_\br uses the _\b$_\bq_\bu_\bo_\bt_\be_\b__\br_\be_\bg_\be_\bx_\bp (section 7.4.232 , page 145) variable to
- detect quoted text when displaying the body of the message. This function tog-
- gles the display of the quoted material in the message. It is particularly
- useful when are interested in just the response and there is a large amount of
- quoted text in the way.
-
- s\bsk\bki\bip\bp-\b-q\bqu\buo\bot\bte\bed\bd
- (default: S)
-
- This function will go to the next line of non-quoted text which come after a
- line of quoted text in the internal pager.
-

-
- _\b2_\b._\b6 _\bS_\be_\bn_\bd_\bi_\bn_\bg _\bM_\ba_\bi_\bl
-
- The following bindings are available in the _\bi_\bn_\bd_\be_\bx for sending messages.
-
- m compose compose a new message
- r reply reply to sender
- g group-reply reply to all recipients
- L list-reply reply to mailing list address
- f forward forward message
- b bounce bounce (remail) message
- ESC k mail-key mail a PGP public key to someone
-
- Bouncing a message sends the message as is to the recipient you specify. For-
- warding a message allows you to add comments or modify the message you are for-
- warding. These items are discussed in greater detail in the next chapter

-
- When you want to send an email using mutt-ng, simply press m on your keyboard.
- Then, mutt-ng asks for the recipient via a prompt in the last line:
-
- To:
-
- After you've finished entering the recipient(s), press return. If you want to
- send an email to more than one recipient, separate the email addresses using
- the comma ",". Mutt-ng then asks you for the email subject. Again, press return
- after you've entered it. After that, mutt-ng got the most important information
- from you, and starts up an editor where you can then enter your email.
-
- The editor that is called is selected in the following way: you can e.g. set it
- in the mutt-ng configuration:
-
- set editor = "vim +/^$/ -c ':set tw=72'"
- set editor = "nano"
- set editor = "emacs"
-
- If you don't set your preferred editor in your configuration, mutt-ng first
- looks whether the environment variable $VISUAL is set, and if so, it takes its
- value as editor command. Otherwise, it has a look at $EDITOR and takes its
- value if it is set. If no editor command can be found, mutt-ng simply assumes
- vi to be the default editor, since it's the most widespread editor in the Unix
- world and it's pretty safe to assume that it is installed and available.
-
- When you've finished entering your message, save it and quit your editor. Mutt-
- ng will then present you with a summary screen, the compose menu. On the top,
- you see a summary of the most important available key commands. Below that,
- you see the sender, the recipient(s), Cc and/or Bcc recipient(s), the subject,
-
- The Mutt Next Generation E-Mail Client 15
-
- the reply-to address, and optionally information where the sent email will be
- stored and whether it should be digitally signed and/or encrypted.
-
- Below that, you see a list of "attachments". The mail you've just entered
- before is also an attachment, but due to its special type (it's plain text), it
- will be displayed as the normal message on the receiver's side.
-
- At this point, you can add more attachments, pressing a, you can edit the

+ Similar to many other mail clients, there are two modes in which mail is read in Mutt-ng. The first is the index of messages in the mailbox, which is called the ``index'' in Mutt-ng. The second mode is the display of the message contents. This is called the ``pager.''
- Alternatively, you can configure mutt-ng in a way that most of the above set-
- tings can be edited using the editor. Therefore, you only need to add the fol-
- lowing to your configuration:

+ Furthermore, the following flags reflect who the message is addressed to. They can be customized with the $to_chars variable.

- to the message you are sending. Note that certain operations like composing a
- new mail, replying, forwarding, etc. are not permitted when you are in that
- folder. The %r in _\b$_\bs_\bt_\ba_\bt_\bu_\bs_\b__\bf_\bo_\br_\bm_\ba_\bt (section 7.4.315 , page 164) will change to a

- When you want to reply to an email message, select it in the index menu and
- then press r. Mutt-ng's behaviour is then similar to the behaviour when you
- compose a message: first, you will be asked for the recipient, then for the
- subject, and then, mutt-ng will start the editor with the quote attribution and
- the quoted message. This can e.g. look like the example below.
+5.2. The Pager

+ By default, Mutt-ng uses its builtin pager to display the body of messages. The pager is very similar to the Unix program less though not nearly as featureful.
+<Return> go down one line
+<Space> display the next page (or next message if at the end of a message)
+- go back to the previous page
+n search for next match
+S skip beyond quoted text
+T toggle display of quoted text
+? show key bindings
+/ search for a regular expression (pattern)
+ESC / search backwards for a regular expression
+\ toggle search pattern coloring
+^ jump to the top of the message
- You can start editing the email message. It is strongly recommended to put your
- answer _\bb_\be_\bl_\bo_\bw the quoted text and to only quote what is really necessary and
- that you refer to. Putting your answer on top of the quoted message, is,
- although very widespread, very often not considered to be a polite way to
- answer emails.
+ In addition, many of the functions from the index are available in the pager, such as delete-message or copy-message (this is one advantage over using an external pager to view messages).
- The quote attribution is configurable, by default it is set to
+ Also, the internal pager supports a couple other advanced features. For one, it will accept and translate the ``standard'' nroff sequences for bold and underline. These sequences are a series of either the letter, backspace (^H), the letter again for bold or the letter, backspace, ``_'' for denoting underline. Mutt-ng will attempt to display these in bold and underline respectively if your terminal supports them. If not, you can use the bold and underline color objects to specify a color or mono attribute for them.
- set attribution = "On %d, %n wrote:"
+ Additionally, the internal pager supports the ANSI escape sequences for character attributes. Mutt-ng translates them into the correct color and character settings. The sequences Mutt-ng supports are:
+ESC [ Ps;Ps;Ps;...;Ps m
+where Ps =
+0 All Attributes Off
+1 Bold on
+4 Underline on
+5 Blink on
+7 Reverse video on
+3x Foreground color is x
+4x Background color is x
- It can also be set to something more compact, e.g.
+Colors are
+0 black
+1 red
+2 green
+3 yellow
+4 blue
+5 magenta
+6 cyan
+7 white
- set attribution = "attribution="* %n <%a> [%(%y-%m-%d %H:%M)]:"
+ Mutt-ng uses these attributes for handling text/enriched messages, and they can also be used by an external autoview script for highlighting purposes. Note: If you change the colors for your display, for example by changing the color associated with color2 for your xterm, then that color will be used instead of green.
- The example above results in the following attribution:

+ When the mailbox is sorted by threads, there are a few additional functions available in the index and pager modes.
+^D delete-thread delete all messages in the current thread
+^U undelete-thread undelete all messages in the current thread
+^N next-thread jump to the start of the next thread
+^P previous-thread jump to the start of the previous thread
+^R read-thread mark the current thread as read
+ESC d delete-subthread delete all messages in the current subthread
+ESC u undelete-subthread undelete all messages in the current subthread
+ESC n next-subthread jump to the start of the next subthread
+ESC p previous-subthread jump to the start of the previous subthread
+ESC r read-subthread mark the current subthread as read
+ESC t tag-thread toggle the tag on the current thread
+ESC v collapse-thread toggle collapse for the current thread
+ESC V collapse-all toggle collapse for all threads
+P parent-message jump to parent message in thread
- Generally, try to keep your attribution short yet information-rich. It is _\bn_\bo_\bt
- the right place for witty quotes, long "attribution" novels or anything like
- that: the right place for such things is - if at all - the email signature at
- the very bottom of the message.
+ Note: Collapsing a thread displays only the first message in the thread and hides the others. This is useful when threads contain so many messages that you can only see a handful of threads on the screen. See %M in index-format. For example, you could use "%?M?(#%03M)&(%4l)?" in index-format to optionally display the number of hidden messages if the thread is collapsed.
- When you're done with writing your message, save and quit the editor. As
- before, you will return to the compose menu, which is used in the same way as

+ create-alias (default: a)
- _\b2_\b._\b6_\b._\b2_\b._\b2 _\bG_\br_\bo_\bu_\bp _\bR_\be_\bp_\bl_\bi_\be_\bs
+ Creates a new alias based upon the current message (or prompts for a new one). Once editing is complete, an alias command is added to the file specified by the alias-file variable for future use. Note: Specifying an alias-file does not add the aliases specified there-in, you must also source the file.
- In the situation where a group of people uses email as a discussion, most of
- the emails will have one or more recipients, and probably several "Cc:" recipi-
- ents. The group reply functionality ensures that when you press g instead of r
- to do a reply, each and every recipient that is contained in the original mes-
- sage will receive a copy of the message, either as normal recipient or as "Cc:"
- recipient.
+ check-traditional-pgp (default: ESC P)
- _\b2_\b._\b6_\b._\b2_\b._\b3 _\bL_\bi_\bs_\bt _\bR_\be_\bp_\bl_\bi_\be_\bs
+ This function will search the current message for content signed or encrypted with PGP the "traditional" way, that is, without proper MIME tagging. Technically, this function will temporarily change the MIME content types of the body parts containing PGP data; this is similar to the edit-type function's effect.
- When you use mailing lists, it's generally better to send your reply to a mes-
- sage only to the list instead of the list and the original author. To make this
- easy to use, mutt-ng features list replies.
+ display-toggle-weed (default: h)
- To do a list reply, simply press L. If the email contains a Mail-Followup-To:
- header, its value will be used as reply address. Otherwise, mutt-ng searches
- through all mail addresses in the original message and tries to match them a
- list of regular expressions which can be specified using the lists command. If
- any of the regular expression matches, a mailing list address has been found,
- and it will be used as reply address.
+ Toggles the weeding of message header fields specified by ignore commands.
- lists linuxevent@luga\.at vuln-dev@ mutt-ng-users@
+ edit (default: e)
- Nowadays, most mailing list software like GNU Mailman adds a Mail-Followup-To:
- header to their emails anyway, so setting lists is hardly ever necessary in
- practice.
+ This command (available in the ``index'' and ``pager'') allows you to edit the raw current message as it's present in the mail folder. After you have finished editing, the changed message will be appended to the current folder, and the original message will be marked for deletion.
- _\b2_\b._\b6_\b._\b3 _\bE_\bd_\bi_\bt_\bi_\bn_\bg _\bt_\bh_\be _\bm_\be_\bs_\bs_\ba_\bg_\be _\bh_\be_\ba_\bd_\be_\br
+ edit-type (default: ^E on the attachment menu, and in the pager and index menus; ^T on the compose menu)
- When editing the header of your outgoing message, there are a couple of special
- features available.
+ This command is used to temporarily edit an attachment's content type to fix, for instance, bogus character set parameters. When invoked from the index or from the pager, you'll have the opportunity to edit the top-level attachment's content type. On the attach-menu, you can change any attachment's content type. These changes are not persistent, and get lost upon changing folders.
- If you specify
+ Note that this command is also available on the compose-menu. There, it's used to fine-tune the properties of attachments you are going to send.
- Fcc: _\bf_\bi_\bl_\be_\bn_\ba_\bm_\be
+ enter-command (default: ``:'')
- Mutt-ng will pick up _\bf_\bi_\bl_\be_\bn_\ba_\bm_\be just as if you had used the _\be_\bd_\bi_\bt_\b-_\bf_\bc_\bc function in
- the _\bc_\bo_\bm_\bp_\bo_\bs_\be menu.
+ This command is used to execute any command you would normally put in a configuration file. A common use is to check the settings of variables, or in conjunction with macro to change settings on the fly.
- You can also attach files to your message by specifying
+ extract-keys (default: ^K)
- The Mutt Next Generation E-Mail Client 18
+ This command extracts PGP public keys from the current or tagged message(s) and adds them to your PGP public key ring.
- Attach: _\bf_\bi_\bl_\be_\bn_\ba_\bm_\be [ _\bd_\be_\bs_\bc_\br_\bi_\bp_\bt_\bi_\bo_\bn ]
+ forget-passphrase (default: ^F)
- where _\bf_\bi_\bl_\be_\bn_\ba_\bm_\be is the file to attach and _\bd_\be_\bs_\bc_\br_\bi_\bp_\bt_\bi_\bo_\bn is an optional string to
- use as the description of the attached file.
+ This command wipes the passphrase(s) from memory. It is useful, if you misspelled the passphrase.
- When replying to messages, if you remove the _\bI_\bn_\b-_\bR_\be_\bp_\bl_\by_\b-_\bT_\bo_\b: field from the header
- field, Mutt-ng will not generate a _\bR_\be_\bf_\be_\br_\be_\bn_\bc_\be_\bs_\b: field, which allows you to cre-
- ate a new message thread.
+ list-reply (default: L)
- Also see _\be_\bd_\bi_\bt_\b__\bh_\be_\ba_\bd_\be_\br_\bs (section 7.4.59 , page 102).
+ Reply to the current or tagged message(s) by extracting any addresses which match the regular expressions given by the lists commands, but also honor any Mail-Followup-To header(s) if the honor-followup-to configuration variable is set. Using this when replying to messages posted to mailing lists helps avoid duplicate copies being sent to the author of the message you are replying to.

+ pipe-message (default: |)
- If you want to use PGP, you can specify
+ Asks for an external Unix command and pipes the current or tagged message(s) to it. The variables pipe-decode, pipe-split, pipe-sep and wait-key control the exact behavior of this function.
- Pgp: [ E | S | S_\b<_\bi_\bd_\b> ]
+ resend-message (default: ESC e)
- ``E'' encrypts, ``S'' signs and ``S<id>'' signs with the given key, setting
- _\b$_\bp_\bg_\bp_\b__\bs_\bi_\bg_\bn_\b__\ba_\bs (section 7.4.199 , page 138) permanently.
+ With resend-message, mutt takes the current message as a template for a new message. This function is best described as "recall from arbitrary folders". It can conveniently be used to forward MIME messages while preserving the original mail structure. Note that the amount of headers included here depends on the value of the weed variable.
- If you have told mutt to PGP encrypt a message, it will guide you through a key
- selection process when you try to send the message. Mutt-ng will not ask you
- any questions about keys which have a certified user ID matching one of the
- message recipients' mail addresses. However, there may be situations in which
- there are several keys, weakly certified user ID fields, or where no matching
- keys can be found.
+ This function is also available from the attachment menu. You can use this to easily resend a message which was included with a bounce message as a message/rfc822 body part.
- In these cases, you are dropped into a menu with a list of keys from which you
- can select one. When you quit this menu, or mutt can't find any matching keys,
- you are prompted for a user ID. You can, as usually, abort this prompt using
- ^G. When you do so, mutt will return to the compose screen.
+ shell-escape (default: !)
- Once you have successfully finished the key selection, the message will be
- encrypted using the selected public keys, and sent out.
+ Asks for an external Unix command and executes it. The wait-key can be used to control whether Mutt-ng will wait for a key to be pressed when the command returns (presumably to let the user read the output of the command), based on the return status of the named command.
- Most fields of the entries in the key selection menu (see also _\b$_\bp_\bg_\bp_\b__\be_\bn_\bt_\br_\by_\b__\bf_\bo_\br_\b-
- _\bm_\ba_\bt (section 7.4.186 , page 134)) have obvious meanings. But some explana-
- tions on the capabilities, flags, and validity fields are in order.
+ toggle-quoted (default: T)
- The flags sequence (%f) will expand to one of the following flags:
+ The pager uses the quote-regexp variable to detect quoted text when displaying the body of the message. This function toggles the display of the quoted material in the message. It is particularly useful when are interested in just the response and there is a large amount of quoted text in the way.
- R The key has been revoked and can't be used.
- X The key is expired and can't be used.
- d You have marked the key as disabled.
- c There are unknown critical self-signature
- packets.
+ skip-quoted (default: S)
- The capabilities field (%c) expands to a two-character sequence representing a
- key's capabilities. The first character gives the key's encryption capabili-
- ties: A minus sign (-\b-) means that the key cannot be used for encryption. A dot
- (.\b.) means that it's marked as a signature key in one of the user IDs, but may

+g group-reply reply to all recipients
+L list-reply reply to mailing list address
+f forward forward message

+ESC k mail-key mail a PGP public key to someone
- The second character indicates the key's signing capabilities. Once again, a
- ``-\b-'' implies ``not for signing'', ``.\b.'' implies that the key is marked as an
- encryption key in one of the user-ids, and ``s\bs'' denotes a key which can be
- used for signing.
+ Bouncing a message sends the message as is to the recipient you specify. Forwarding a message allows you to add comments or modify the message you are forwarding. These items are discussed in greater detail in the next chapter forwarding-mail.
- Finally, the validity field (%t) indicates how well-certified a user-id is. A
- question mark (?\b?) indicates undefined validity, a minus character (-\b-) marks an
- untrusted association, a space character means a partially trusted association,
- and a plus character (+\b+) indicates complete validity.

+ When you want to send an email using mutt-ng, simply press m on your keyboard. Then, mutt-ng asks for the recipient via a prompt in the last line:
+To:
- You may also have configured mutt to co-operate with Mixmaster, an anonymous
- remailer. Mixmaster permits you to send your messages anonymously using a
- chain of remailers. Mixmaster support in mutt is for mixmaster version 2.04
- (beta 45 appears to be the latest) and 2.03. It does not support earlier ver-
- sions or the later so-called version 3 betas, of which the latest appears to be
- called 2.9b23.
+ After you've finished entering the recipient(s), press return. If you want to send an email to more than one recipient, separate the email addresses using the comma ",". Mutt-ng then asks you for the email subject. Again, press return after you've entered it. After that, mutt-ng got the most important information from you, and starts up an editor where you can then enter your email.
- To use it, you'll have to obey certain restrictions. Most important, you can-
- not use the Cc and Bcc headers. To tell Mutt-ng to use mixmaster, you have to
- select a remailer chain, using the mix function on the compose menu.
+ The editor that is called is selected in the following way: you can e.g. set it in the mutt-ng configuration:
+set editor = "vim +/^$/ -c ':set tw=72'"
+set editor = "nano"
+set editor = "emacs"
- The chain selection screen is divided into two parts. In the (larger) upper
- part, you get a list of remailers you may use. In the lower part, you see the
- currently selected chain of remailers.
+ If you don't set your preferred editor in your configuration, mutt-ng first looks whether the environment variable $VISUAL is set, and if so, it takes its value as editor command. Otherwise, it has a look at $EDITOR and takes its value if it is set. If no editor command can be found, mutt-ng simply assumes vi to be the default editor, since it's the most widespread editor in the Unix world and it's pretty safe to assume that it is installed and available.
- You can navigate in the chain using the chain-prev and chain-next functions,
- which are by default bound to the left and right arrows and to the h and l keys
- (think vi keyboard bindings). To insert a remailer at the current chain posi-
- tion, use the insert function. To append a remailer behind the current chain
- position, use select-entry or append. You can also delete entries from the
- chain, using the corresponding function. Finally, to abandon your changes,
- leave the menu, or accept them pressing (by default) the Return key.
+ When you've finished entering your message, save it and quit your editor. Mutt-ng will then present you with a summary screen, the compose menu. On the top, you see a summary of the most important available key commands. Below that, you see the sender, the recipient(s), Cc and/or Bcc recipient(s), the subject, the reply-to address, and optionally information where the sent email will be stored and whether it should be digitally signed and/or encrypted.
- Note that different remailers do have different capabilities, indicated in the
- %c entry of the remailer menu lines (see _\b$_\bm_\bi_\bx_\b__\be_\bn_\bt_\br_\by_\b__\bf_\bo_\br_\bm_\ba_\bt (section 7.4.146 ,
- page 124)). Most important is the ``middleman'' capability, indicated by a
- capital ``M'': This means that the remailer in question cannot be used as the
- final element of a chain, but will only forward messages to other mixmaster
- remailers. For details on the other capabilities, please have a look at the
- mixmaster documentation.
+ Below that, you see a list of "attachments". The mail you've just entered before is also an attachment, but due to its special type (it's plain text), it will be displayed as the normal message on the receiver's side.
- _\b2_\b._\b7 _\bF_\bo_\br_\bw_\ba_\br_\bd_\bi_\bn_\bg _\ba_\bn_\bd _\bB_\bo_\bu_\bn_\bc_\bi_\bn_\bg _\bM_\ba_\bi_\bl
+ At this point, you can add more attachments, pressing a, you can edit the recipient addresses, pressing t for the "To:" field, c for the "Cc:" field, and b for the "Bcc: field. You can also edit the subject the subject by simply pressing s or the email message that you've entered before by pressing e. You will then again return to the editor. You can even edit the sender, by pressing <esc>f, but this shall only be used with caution.

+ Alternatively, you can configure mutt-ng in a way that most of the above settings can be edited using the editor. Therefore, you only need to add the following to your configuration:
+set edit_headers
- Often, it is necessary to forward mails to other people. Therefore, mutt-ng
- supports forwarding messages in two different ways.
+ Once you have finished editing the body of your mail message, you are returned to the compose menu. The following options are available:
+a attach-file attach a file
+A attach-message attach message(s) to the message
+ESC k attach-key attach a PGP public key
+d edit-description edit description on attachment
+D detach-file detach a file
+t edit-to edit the To field
+ESC f edit-from edit the From field

+q quit quit (abort) sending the message
+w write-fcc write the message to a folder
+i ispell check spelling (if available on your system)

- The first one is regular forwarding, as you probably know it from other mail
- clients. You simply press f, enter the recipient email address, the subject of
- the forwarded email, and then you can edit the message to be forwarded in the
- editor. The forwarded message is separated from the rest of the message via the
- two following markers:
+ Note: The attach-message function will prompt you for a folder to attach messages from. You can now tag messages in that folder and they will be attached to the message you are sending. Note that certain operations like composing a new mail, replying, forwarding, etc. are not permitted when you are in that folder. The %r in status-format will change to a 'A' to indicate that you are in attach-message mode.

+ You can start editing the email message. It is strongly recommended to put your answer below the quoted text and to only quote what is really necessary and that you refer to. Putting your answer on top of the quoted message, is, although very widespread, very often not considered to be a polite way to answer emails.
- When you're done with editing the mail, save and quit the editor, and you will
- return to the compose menu, the same menu you also encounter when composing or
- replying to mails.
+ The quote attribution is configurable, by default it is set to
+set attribution = "On %d, %n wrote:"
- The second mode of forwarding emails with mutt-ng is the so-called _\bb_\bo_\bu_\bn_\bc_\bi_\bn_\bg:
- when you bounce an email to another address, it will be sent in practically the
- same format you send it (except for headers that are created during transport-
- ing the message). To bounce a message, press b and enter the recipient email
- address. By default, you are then asked whether you really want to bounce the
- message to the specified recipient. If you answer with yes, the message will
- then be bounced.
+ It can also be set to something more compact, e.g.
+set attribution = "attribution="* %n <%a> [%(%y-%m-%d %H:%M)]:"
- To the recipient, the bounced email will look as if he got it like a regular
- email where he was Bcc: recipient. The only possibility to find out whether it
- was a bounced email is to carefully study the email headers and to find out
- which host really sent the email.
+ The example above results in the following attribution:
+* Michael Svensson <svensson@foobar.com> [05-03-06 17:02]:
+> Bill, can you please send last month's progress report to Mr.
+> Morgan? We also urgently need the cost estimation for the new
+> production server that we want to set up before our customer's
+> project will go live.
- _\b2_\b._\b8 _\bP_\bo_\bs_\bt_\bp_\bo_\bn_\bi_\bn_\bg _\bM_\ba_\bi_\bl
+ Generally, try to keep your attribution short yet information-rich. It is not the right place for witty quotes, long "attribution" novels or anything like that: the right place for such things is - if at all - the email signature at the very bottom of the message.
- At times it is desirable to delay sending a message that you have already begun
- to compose. When the _\bp_\bo_\bs_\bt_\bp_\bo_\bn_\be_\b-_\bm_\be_\bs_\bs_\ba_\bg_\be function is used in the _\bc_\bo_\bm_\bp_\bo_\bs_\be menu,
- the body of your message and attachments are stored in the mailbox specified by
- the _\b$_\bp_\bo_\bs_\bt_\bp_\bo_\bn_\be_\bd (section 7.4.221 , page 142) variable. This means that you can
- recall the message even if you exit Mutt-ng and then restart it at a later
- time.
+ When you're done with writing your message, save and quit the editor. As before, you will return to the compose menu, which is used in the same way as before.
- Once a message is postponed, there are several ways to resume it. From the
- command line you can use the ``-p'' option, or if you _\bc_\bo_\bm_\bp_\bo_\bs_\be a new message
+6.2.2. Group Replies
- The Mutt Next Generation E-Mail Client 21
+ In the situation where a group of people uses email as a discussion, most of the emails will have one or more recipients, and probably several "Cc:" recipients. The group reply functionality ensures that when you press g instead of r to do a reply, each and every recipient that is contained in the original message will receive a copy of the message, either as normal recipient or as "Cc:" recipient.
- from the _\bi_\bn_\bd_\be_\bx or _\bp_\ba_\bg_\be_\br you will be prompted if postponed messages exist. If
- multiple messages are currently postponed, the _\bp_\bo_\bs_\bt_\bp_\bo_\bn_\be_\bd menu will pop up and
- you can select which message you would like to resume.
+6.2.3. List Replies
- N\bNo\bot\bte\be:\b: If you postpone a reply to a message, the reply setting of the message is
- only updated when you actually finish the message and send it. Also, you must
- be in the same folder with the message you replied to for the status of the
- message to be updated.
+ When you use mailing lists, it's generally better to send your reply to a message only to the list instead of the list and the original author. To make this easy to use, mutt-ng features list replies.
- See also the _\b$_\bp_\bo_\bs_\bt_\bp_\bo_\bn_\be (section 7.4.220 , page 142) quad-option.
+ To do a list reply, simply press L. If the email contains a Mail-Followup-To: header, its value will be used as reply address. Otherwise, mutt-ng searches through all mail addresses in the original message and tries to match them a list of regular expressions which can be specified using the lists command. If any of the regular expression matches, a mailing list address has been found, and it will be used as reply address.
+lists linuxevent@luga\.at vuln-dev@ mutt-ng-users@
- _\b3_\b. _\bC_\bo_\bn_\bf_\bi_\bg_\bu_\br_\ba_\bt_\bi_\bo_\bn
+ Nowadays, most mailing list software like GNU Mailman adds a Mail-Followup-To: header to their emails anyway, so setting lists is hardly ever necessary in practice.

+6.3. Editing the message header
- While the default configuration (or ``preferences'') make Mutt-ng usable right
- out of the box, it is often desirable to tailor Mutt-ng to suit your own
- tastes. When Mutt-ng is first invoked, it will attempt to read the ``system''
- configuration file (defaults set by your local system administrator), unless
- the ``-n'' _\bc_\bo_\bm_\bm_\ba_\bn_\bd _\bl_\bi_\bn_\be (section 7.1 , page 82) option is specified. This
- file is typically /usr/local/share/muttng/Muttngrc or /etc/Muttngrc, Mutt-ng
- users will find this file in /usr/local/share/muttng/Muttrc or /etc/Muttngrc.
- Mutt will next look for a file named .muttrc in your home directory, Mutt-ng
- will look for .muttngrc. If this file does not exist and your home directory
- has a subdirectory named .mutt, mutt try to load a file named .muttng/muttngrc.
+ When editing the header of your outgoing message, there are a couple of special features available.
- .muttrc (or .muttngrc for Mutt-ng) is the file where you will usually place
- your _\bc_\bo_\bm_\bm_\ba_\bn_\bd_\bs (section 7.3 , page 85) to configure Mutt-ng.
+ If you specify Fcc: filename Mutt-ng will pick up filename just as if you had used the edit-fcc function in the compose menu.
- _\b3_\b._\b2 _\bB_\ba_\bs_\bi_\bc _\bS_\by_\bn_\bt_\ba_\bx _\bo_\bf _\bI_\bn_\bi_\bt_\bi_\ba_\bl_\bi_\bz_\ba_\bt_\bi_\bo_\bn _\bF_\bi_\bl_\be_\bs
+ You can also attach files to your message by specifying Attach: filename [ description ] where filename is the file to attach and description is an optional string to use as the description of the attached file.
- An initialization file consists of a series of _\bc_\bo_\bm_\bm_\ba_\bn_\bd_\bs (section 7.3 , page
- 85). Each line of the file may contain one or more commands. When multiple
- commands are used, they must be separated by a semicolon (;).
+ When replying to messages, if you remove the In-Reply-To: field from the header field, Mutt-ng will not generate a References: field, which allows you to create a new message thread.
- set realname='Mutt-ng user' ; ignore x-
+ Also see edit-headers.
- The hash mark, or pound sign (``#''), is used as a ``comment'' character. You
- can use it to annotate your initialization file. All text after the comment
- character to the end of the line is ignored. For example,
+6.4. Using Mutt-ng with PGP
- my_hdr X-Disclaimer: Why are you listening to me? # This is a comment
+ If you want to use PGP, you can specify
- Single quotes (') and double quotes (') can be used to quote strings which
+ Pgp: [ E | S | S<id> ]
- The Mutt Next Generation E-Mail Client 22
+ ``E'' encrypts, ``S'' signs and ``S<id>'' signs with the given key, setting pgp-sign-as permanently.
- contain spaces or other special characters. The difference between the two
- types of quotes is similar to that of many popular shell programs, namely that
- a single quote is used to specify a literal string (one that is not interpreted
- for shell variables or quoting with a backslash [see next paragraph]), while
- double quotes indicate a string for which should be evaluated. For example,
- backtics are evaluated inside of double quotes, but n\bno\bot\bt for single quotes.
+ If you have told mutt to PGP encrypt a message, it will guide you through a key selection process when you try to send the message. Mutt-ng will not ask you any questions about keys which have a certified user ID matching one of the message recipients' mail addresses. However, there may be situations in which there are several keys, weakly certified user ID fields, or where no matching keys can be found.
- \ quotes the next character, just as in shells such as bash and zsh. For exam-
- ple, if want to put quotes ``''' inside of a string, you can use ``\'' to force
- the next character to be a literal instead of interpreted character.
+ In these cases, you are dropped into a menu with a list of keys from which you can select one. When you quit this menu, or mutt can't find any matching keys, you are prompted for a user ID. You can, as usually, abort this prompt using ^G. When you do so, mutt will return to the compose screen.
- set realname="Michael \"MuttDude\" Elkins"
+ Once you have successfully finished the key selection, the message will be encrypted using the selected public keys, and sent out.
- ``\\'' means to insert a literal ``\'' into the line. ``\n'' and ``\r'' have
- their usual C meanings of linefeed and carriage-return, respectively.
+ Most fields of the entries in the key selection menu (see also pgp-entry-format) have obvious meanings. But some explanations on the capabilities, flags, and validity fields are in order.
- A \ at the end of a line can be used to split commands over multiple lines,
- provided that the split points don't appear in the middle of command names.
+ The flags sequence (%f) will expand to one of the following flags:
+R The key has been revoked and can't be used.
+X The key is expired and can't be used.
+d You have marked the key as disabled.
+c There are unknown critical self-signature
+ packets.
- Please note that, unlike the various shells, mutt-ng interprets a ``\'' at the
- end of a line also in comments. This allows you to disable a command split over
- multiple lines with only one ``#''.
+ The capabilities field (%c) expands to a two-character sequence representing a key's capabilities. The first character gives the key's encryption capabilities: A minus sign (-) means that the key cannot be used for encryption. A dot (.) means that it's marked as a signature key in one of the user IDs, but may also be used for encryption. The letter e indicates that this key can be used for encryption.
- # folder-hook . \
- set realname="Michael \"MuttDude\" Elkins"
+ The second character indicates the key's signing capabilities. Once again, a ``-'' implies ``not for signing'', ``.'' implies that the key is marked as an encryption key in one of the user-ids, and ``s'' denotes a key which can be used for signing.
- When testing your config files, beware the following caveat. The backslash at
- the end of the commented line extends the current line with the next line -
- then referred to as a ``continuation line''. As the first line is commented
- with a hash (#) all following continuation lines are also part of a comment and
- therefore are ignored, too. So take care of comments when continuation lines
- are involved within your setup files!
+ Finally, the validity field (%t) indicates how well-certified a user-id is. A question mark (?) indicates undefined validity, a minus character (-) marks an untrusted association, a space character means a partially trusted association, and a plus character (+) indicates complete validity.
- Abstract example:
+6.5. Sending anonymous messages via mixmaster
- line1\
- line2a # line2b\
- line3\
- line4
- line5
+ You may also have configured mutt to co-operate with Mixmaster, an anonymous remailer. Mixmaster permits you to send your messages anonymously using a chain of remailers. Mixmaster support in mutt is for mixmaster version 2.04 (beta 45 appears to be the latest) and 2.03. It does not support earlier versions or the later so-called version 3 betas, of which the latest appears to be called 2.9b23.
- line1 ``continues'' until line4. however, the part after the # is a comment
- which includes line3 and line4. line5 is a new line of its own and thus is
- interpreted again.
+ To use it, you'll have to obey certain restrictions. Most important, you cannot use the Cc and Bcc headers. To tell Mutt-ng to use mixmaster, you have to select a remailer chain, using the mix function on the compose menu.
- The commands understood by mutt are explained in the next paragraphs. For a
- complete list, see the _\bc_\bo_\bm_\bm_\ba_\bn_\bd _\br_\be_\bf_\be_\br_\be_\bn_\bc_\be (section 7.3 , page 85).
+ The chain selection screen is divided into two parts. In the (larger) upper part, you get a list of remailers you may use. In the lower part, you see the currently selected chain of remailers.
- The Mutt Next Generation E-Mail Client 23
+ You can navigate in the chain using the chain-prev and chain-next functions, which are by default bound to the left and right arrows and to the h and l keys (think vi keyboard bindings). To insert a remailer at the current chain position, use the insert function. To append a remailer behind the current chain position, use select-entry or append. You can also delete entries from the chain, using the corresponding function. Finally, to abandon your changes, leave the menu, or accept them pressing (by default) the Return key.
- _\b3_\b._\b3 _\bV_\ba_\br_\bi_\ba_\bb_\bl_\be _\bE_\bx_\bp_\ba_\bn_\bs_\bi_\bo_\bn
+ Note that different remailers do have different capabilities, indicated in the %c entry of the remailer menu lines (see mix-entry-format). Most important is the ``middleman'' capability, indicated by a capital ``M'': This means that the remailer in question cannot be used as the final element of a chain, but will only forward messages to other mixmaster remailers. For details on the other capabilities, please have a look at the mixmaster documentation.

+7. Forwarding and Bouncing Mail
- It is possible to substitute the output of a Unix command in an initialization
- file. This is accomplished by enclosing the command in backquotes (``) as in,
- for example:
+ Often, it is necessary to forward mails to other people. Therefore, mutt-ng supports forwarding messages in two different ways.
- my_hdr X-Operating-System: `uname -a`
+ The first one is regular forwarding, as you probably know it from other mail clients. You simply press f, enter the recipient email address, the subject of the forwarded email, and then you can edit the message to be forwarded in the editor. The forwarded message is separated from the rest of the message via the two following markers:
+----- Forwarded message from Lucas User <luser@example.com> -----
- The output of the Unix command ``uname -a'' will be substituted before the line
- is parsed. Note that since initialization files are line oriented, only the
- first line of output from the Unix command will be substituted.
+From: Lucas User <luser@example.com>
+Date: Thu, 02 Dec 2004 03:08:34 +0100
+To: Michael Random <mrandom@example.com>
+Subject: Re: blackmail

+Pay me EUR 50,000.- cash or your favorite stuffed animal will die
+a horrible death.
- UNIX environments can be accessed like the way it is done in shells like sh and
- bash: Prepend the name of the environment by a ``$'' sign. For example,
- set record=+sent_on_$HOSTNAME
+----- End forwarded message -----
- sets the _\b$_\br_\be_\bc_\bo_\br_\bd (section 7.4.237 , page 146) variable to the string _\b+_\bs_\be_\bn_\bt_\b__\bo_\bn_\b_
- and appends the value of the evironment variable $HOSTNAME.
+ When you're done with editing the mail, save and quit the editor, and you will return to the compose menu, the same menu you also encounter when composing or replying to mails.
- N\bNo\bot\bte\be:\b: There will be no warning if an environment variable is not defined. The
- result will of the expansion will then be empty.
+ The second mode of forwarding emails with mutt-ng is the so-called bouncing: when you bounce an email to another address, it will be sent in practically the same format you send it (except for headers that are created during transporting the message). To bounce a message, press b and enter the recipient email address. By default, you are then asked whether you really want to bounce the message to the specified recipient. If you answer with yes, the message will then be bounced.
- _\b3_\b._\b3_\b._\b3 _\bC_\bo_\bn_\bf_\bi_\bg_\bu_\br_\ba_\bt_\bi_\bo_\bn _\bV_\ba_\br_\bi_\ba_\bb_\bl_\be_\bs
+ To the recipient, the bounced email will look as if he got it like a regular email where he was Bcc: recipient. The only possibility to find out whether it was a bounced email is to carefully study the email headers and to find out which host really sent the email.
- As for environment variables, the values of all configuration variables as
- string can be used in the same way, too. For example,
+8. Postponing Mail
- set imap_home_namespace = $folder
+ At times it is desirable to delay sending a message that you have already begun to compose. When the postpone-message function is used in the compose menu, the body of your message and attachments are stored in the mailbox specified by the postponed variable. This means that you can recall the message even if you exit Mutt-ng and then restart it at a later time.
- would set the value of _\b$_\bi_\bm_\ba_\bp_\b__\bh_\bo_\bm_\be_\b__\bn_\ba_\bm_\be_\bs_\bp_\ba_\bc_\be (section 7.4.101 , page 112) to
- the value to which _\b$_\bf_\bo_\bl_\bd_\be_\br (section 7.4.70 , page 104) is _\bc_\bu_\br_\br_\be_\bn_\bt_\bl_\by set to.
+ Once a message is postponed, there are several ways to resume it. From the command line you can use the ``-p'' option, or if you compose a new message from the index or pager you will be prompted if postponed messages exist. If multiple messages are currently postponed, the postponed menu will pop up and you can select which message you would like to resume.
- N\bNo\bot\bte\be:\b: There're no logical links established in such cases so that the the value
- for _\b$_\bi_\bm_\ba_\bp_\b__\bh_\bo_\bm_\be_\b__\bn_\ba_\bm_\be_\bs_\bp_\ba_\bc_\be (section 7.4.101 , page 112) won't change even if
- _\b$_\bf_\bo_\bl_\bd_\be_\br (section 7.4.70 , page 104) gets changed.
+ Note: If you postpone a reply to a message, the reply setting of the message is only updated when you actually finish the message and send it. Also, you must be in the same folder with the message you replied to for the status of the message to be updated.
- N\bNo\bot\bte\be:\b: There will be no warning if a configuration variable is not defined or is
- empty. The result will of the expansion will then be empty.

- Using this feature, arbitrary sequences can be defined once and recalled and
- reused where necessary. More advanced scenarios could include to save a vari-
- able's value at the beginning of macro sequence and restore it at end.
+ While the default configuration (or ``preferences'') make Mutt-ng usable right out of the box, it is often desirable to tailor Mutt-ng to suit your own tastes. When Mutt-ng is first invoked, it will attempt to read the ``system'' configuration file (defaults set by your local system administrator), unless the ``-n'' commandline option is specified. This file is typically /usr/local/share/muttng/Muttngrc or /etc/Muttngrc, Mutt-ng users will find this file in /usr/local/share/muttng/Muttrc or /etc/Muttngrc. Mutt will next look for a file named .muttrc in your home directory, Mutt-ng will look for .muttngrc. If this file does not exist and your home directory has a subdirectory named .mutt, mutt try to load a file named .muttng/muttngrc.
- When the variable is first defined, the first value it gets assigned is also
- the initial value to which it can be reset using the reset command.
+ .muttrc (or .muttngrc for Mutt-ng) is the file where you will usually place your commands to configure Mutt-ng.
- The complete removal is done via the unset keyword.
+2. Basic Syntax of Initialization Files
- After the following sequence:
+ An initialization file consists of a series of commands. Each line of the file may contain one or more commands. When multiple commands are used, they must be separated by a semicolon (;).
+set realname='Mutt-ng user' ; ignore x-
- set user_foo = 42
- set user_foo = 666
+ The hash mark, or pound sign (``#''), is used as a ``comment'' character. You can use it to annotate your initialization file. All text after the comment character to the end of the line is ignored. For example,
+my_hdr X-Disclaimer: Why are you listening to me? # This is a comment
- the variable $user_foo has a current value of 666 and an initial of 42. The
- query
+ Single quotes (') and double quotes (") can be used to quote strings which contain spaces or other special characters. The difference between the two types of quotes is similar to that of many popular shell programs, namely that a single quote is used to specify a literal string (one that is not interpreted for shell variables or quoting with a backslash [see next paragraph]), while double quotes indicate a string for which should be evaluated. For example, backtics are evaluated inside of double quotes, but not for single quotes.
- set ?user_foo
+ \ quotes the next character, just as in shells such as bash and zsh. For example, if want to put quotes ``"'' inside of a string, you can use ``\'' to force the next character to be a literal instead of interpreted character.
+set realname="Michael \"MuttDude\" Elkins"
- will show 666. After doing the reset via
+ ``\\'' means to insert a literal ``\'' into the line. ``\n'' and ``\r'' have their usual C meanings of linefeed and carriage-return, respectively.
- The Mutt Next Generation E-Mail Client 25
+ A \ at the end of a line can be used to split commands over multiple lines, provided that the split points don't appear in the middle of command names.
- reset user_foo
+ Please note that, unlike the various shells, mutt-ng interprets a ``\'' at the end of a line also in comments. This allows you to disable a command split over multiple lines with only one ``#''.
+# folder-hook . \
+ set realname="Michael \"MuttDude\" Elkins"
- a following query will give 42 as the result. After unsetting it via
+ When testing your config files, beware the following caveat. The backslash at the end of the commented line extends the current line with the next line - then referred to as a ``continuation line''. As the first line is commented with a hash (#) all following continuation lines are also part of a comment and therefore are ignored, too. So take care of comments when continuation lines are involved within your setup files!
- unset user_foo
+ Abstract example:
+line1\
+line2a # line2b\
+line3\
+line4
+line5
- any query or operation (except the noted expansion within other statements)
- will lead to an error message.
+ line1 ``continues'' until line4. however, the part after the # is a comment which includes line3 and line4. line5 is a new line of its own and thus is interpreted again.
- _\b3_\b._\b3_\b._\b5 _\bT_\by_\bp_\be _\bC_\bo_\bn_\bv_\be_\br_\bs_\bi_\bo_\bn_\bs
+ The commands understood by mutt are explained in the next paragraphs. For a complete list, see the commands.
- A note about variable's types during conversion: internally values are stored
- in internal types but for any dump/query or set operation they're converted to
- and from string. That means that there's no need to worry about types when ref-
- erencing any variable. As an example, the following can be used without harm
- (besides makeing muttng very likely behave strange):
+3. Expansion within variables
- set read_inc = 100
- set folder = $read_inc
- set read_inc = $folder
- set user_magic_number = 42
- set folder = $user_magic_number
+ Besides just assign static content to variables, there's plenty of ways of adding external and more or less dynamic content.
- _\b3_\b._\b4 _\bD_\be_\bf_\bi_\bn_\bi_\bn_\bg_\b/_\bU_\bs_\bi_\bn_\bg _\ba_\bl_\bi_\ba_\bs_\be_\bs
+3.1. Commands' Output
- Usage: alias _\bk_\be_\by _\ba_\bd_\bd_\br_\be_\bs_\bs [ , _\ba_\bd_\bd_\br_\be_\bs_\bs, ... ]
+ It is possible to substitute the output of a Unix command in an initialization file. This is accomplished by enclosing the command in backquotes (``) as in, for example:
+my_hdr X-Operating-System: `uname -a`
- It's usually very cumbersome to remember or type out the address of someone you
- are communicating with. Mutt-ng allows you to create ``aliases'' which map a
- short string to a full address.
+ The output of the Unix command ``uname -a'' will be substituted before the line is parsed. Note that since initialization files are line oriented, only the first line of output from the Unix command will be substituted.
- N\bNo\bot\bte\be:\b: if you want to create an alias for a group (by specifying more than one
- address), you m\bmu\bus\bst\bt separate the addresses with a comma (``,'').
+3.2. Environment Variables
- To remove an alias or aliases (``*'' means all aliases):
+ UNIX environments can be accessed like the way it is done in shells like sh and bash: Prepend the name of the environment by a ``$'' sign. For example,
+set record=+sent_on_$HOSTNAME
- unalias [ * | _\bk_\be_\by _\b._\b._\b. ]
+ sets the record variable to the string +sent_on_ and appends the value of the evironment variable $HOSTNAME.
- alias muttdude me@cs.hmc.edu (Michael Elkins)
- alias theguys manny, moe, jack
+ Note: There will be no warning if an environment variable is not defined. The result will of the expansion will then be empty.
- Unlike other mailers, Mutt-ng doesn't require aliases to be defined in a spe-
- cial file. The alias command can appear anywhere in a configuration file, as
- long as this file is _\bs_\bo_\bu_\br_\bc_\be_\bd (section 3.29 , page 45). Consequently, you can
- have multiple alias files, or you can have all aliases defined in your muttrc.
+3.3. Configuration Variables
- On the other hand, the _\bc_\br_\be_\ba_\bt_\be_\b-_\ba_\bl_\bi_\ba_\bs (section 2.5.4 , page 11) function can use
+ As for environment variables, the values of all configuration variables as string can be used in the same way, too. For example,
+set imap_home_namespace = $folder
- The Mutt Next Generation E-Mail Client 26
+ would set the value of imap-home-namespace to the value to which folder is currently set to.
- only one file, the one pointed to by the _\b$_\ba_\bl_\bi_\ba_\bs_\b__\bf_\bi_\bl_\be (section 7.4.5 , page 89)
- variable (which is ~/.muttrc by default). This file is not special either, in
- the sense that Mutt-ng will happily append aliases to any file, but in order
- for the new aliases to take effect you need to explicitly _\bs_\bo_\bu_\br_\bc_\be (section
- 3.29 , page 45) this file too.
+ Note: There're no logical links established in such cases so that the the value for imap-home-namespace won't change even if folder gets changed.
- For example:
+ Note: There will be no warning if a configuration variable is not defined or is empty. The result will of the expansion will then be empty.
- source /usr/local/share/Mutt-ng.aliases
- source ~/.mail_aliases
- set alias_file=~/.mail_aliases
+3.4. Self-Defined Variables
- To use aliases, you merely use the alias at any place in mutt where mutt
- prompts for addresses, such as the _\bT_\bo_\b: or _\bC_\bc_\b: prompt. You can also enter
- aliases in your editor at the appropriate headers if you have the _\b$_\be_\bd_\bi_\bt_\b__\bh_\be_\ba_\bd_\be_\br_\bs
- (section 7.4.59 , page 102) variable set.
+ Mutt-ng flexibly allows users to define their own variables. To avoid conflicts with the standard set and to prevent misleading error messages, there's a reserved namespace for them: all user-defined variables must be prefixed with user_ and can be used just like any ordinary configuration or environment variable.
- In addition, at the various address prompts, you can use the tab character to
- expand a partial alias to the full alias. If there are multiple matches, mutt
- will bring up a menu with the matching aliases. In order to be presented with
- the full list of aliases, you must hit tab with out a partial alias, such as at
- the beginning of the prompt or after a comma denoting multiple addresses.
+ For example, to view the manual, users can either define two macros like the following
+macro generic <F1> "!less -r /path/to/manual" "Show manual"
+macro pager <F1> "!less -r /path/to/manual" "Show manual"
- In the alias menu, you can select as many aliases as you want with the _\bs_\be_\bl_\be_\bc_\bt_\b-
- _\be_\bn_\bt_\br_\by key (default: RET), and use the _\be_\bx_\bi_\bt key (default: q) to return to the
- address prompt.
+ for generic, pager and index. The alternative is to define a custom variable like so:
+set user_manualcmd = "!less -r /path/to_manual"
+macro generic <F1> "$user_manualcmd<enter>" "Show manual"
+macro pager <F1> "$user_manualcmd<enter>" "Show manual"
+macro index <F1> "$user_manualcmd<enter>" "Show manual"
- _\b3_\b._\b5 _\bC_\bh_\ba_\bn_\bg_\bi_\bn_\bg _\bt_\bh_\be _\bd_\be_\bf_\ba_\bu_\bl_\bt _\bk_\be_\by _\bb_\bi_\bn_\bd_\bi_\bn_\bg_\bs
+ to re-use the command sequence as in:
+macro index <F2> "$user_manualcmd | grep '\^[ ]\\+~. '" "Show Patterns"
- Usage: bind _\bm_\ba_\bp _\bk_\be_\by _\bf_\bu_\bn_\bc_\bt_\bi_\bo_\bn
+ Using this feature, arbitrary sequences can be defined once and recalled and reused where necessary. More advanced scenarios could include to save a variable's value at the beginning of macro sequence and restore it at end.
- This command allows you to change the default key bindings (operation invoked
- when pressing a key).
+ When the variable is first defined, the first value it gets assigned is also the initial value to which it can be reset using the reset command.
- _\bm_\ba_\bp specifies in which menu the binding belongs. Multiple maps may be speci-
- fied by separating them with commas (no additional whitespace is allowed). The
- currently defined maps are:
+ The complete removal is done via the unset keyword.
- generic
- This is not a real menu, but is used as a fallback for all of the
- other menus except for the pager and editor modes. If a key is not
- defined in another menu, Mutt-ng will look for a binding to use in
- this menu. This allows you to bind a key to a certain function in
- multiple menus instead of having multiple bind statements to accom-
- plish the same task.
+ After the following sequence:
+set user_foo = 42
+set user_foo = 666
- alias
- The alias menu is the list of your personal aliases as defined in
+ the variable $user_foo has a current value of 666 and an initial of 42. The query
+set ?user_foo
- The Mutt Next Generation E-Mail Client 27
+ will show 666. After doing the reset via
+reset user_foo
- your muttrc. It is the mapping from a short alias name to the full
- email address(es) of the recipient(s).
+ a following query will give 42 as the result. After unsetting it via
+unset user_foo
- attach
- The attachment menu is used to access the attachments on received
- messages.
+ any query or operation (except the noted expansion within other statements) will lead to an error message.
- browser
- The browser is used for both browsing the local directory struc-
- ture, and for listing all of your incoming mailboxes.
+3.5. Pre-Defined Variables
- editor
- The editor is the line-based editor the user enters text data.
+ In order to allow users to share one setup over a number of different machines without having to change its contents, there's a number of pre-defined variables. These are prefixed with muttng_ and are read-only, i.e. they cannot be set, unset or reset. The reference chapter lists all available variables.
- index
- The index is the list of messages contained in a mailbox.
+ Please consult the local copy of your manual for their values as they may differ from different manual sources. Where the manual is installed in can be queried (already using such a variable) by running:
+muttng -Q muttng_docdir
- compose
- The compose menu is the screen used when sending a new message.
+ To extend the example for viewing the manual via self-defined variables, it can be made more readable and more portable by changing the real path in:
+set user_manualcmd = '!less -r /path/to_manual'
- pager
- The pager is the mode used to display message/attachment data, and
- help listings.
+ to:
+set user_manualcmd = "!less -r $muttng_docdir/manual.txt"
- pgp
- The pgp menu is used to select the OpenPGP keys used for encrypting
- outgoing messages.
+ which works everywhere if a manual is installed.
- postpone
- The postpone menu is similar to the index menu, except is used when
- recalling a message the user was composing, but saved until later.
+ Please note that by the type of quoting, muttng determines when to expand these values: when it finds double quotes, the value will be expanded during reading the setup files but when it finds single quotes, it'll expand it at runtime as needed.
- _\bk_\be_\by is the key (or key sequence) you wish to bind. To specify a control char-
- acter, use the sequence _\b\_\bC_\bx, where _\bx is the letter of the control character
- (for example, to specify control-A use ``\Ca''). Note that the case of _\bx as
- well as _\b\_\bC is ignored, so that _\b\_\bC_\bA, _\b\_\bC_\ba, _\b\_\bc_\bA and _\b\_\bc_\ba are all equivalent. An
- alternative form is to specify the key as a three digit octal number prefixed
- with a ``\'' (for example _\b\_\b1_\b7_\b7 is equivalent to _\b\_\bc_\b?).
+ For example, the statement
+folder-hook . "set user_current_folder = $muttng_folder_name"
- In addition, _\bk_\be_\by may consist of:
+ will be already be translated to the following when reading the startup files:
+folder-hook . "set user_current_folder = some_folder"
- The Mutt Next Generation E-Mail Client 28
+ with some_folder being the name of the first folder muttng opens. On the contrary,
+folder-hook . 'set user_current_folder = $muttng_folder_name'
- \t tab
- <tab> tab
- <backtab> backtab / shift-tab
- \r carriage return
- \n newline
- \e escape
- <esc> escape
- <up> up arrow
- <down> down arrow
- <left> left arrow
- <right> right arrow
- <pageup> Page Up
- <pagedown> Page Down
- <backspace> Backspace
- <delete> Delete
- <insert> Insert
- <enter> Enter
- <return> Return
- <home> Home
- <end> End
- <space> Space bar
- <f1> function key 1
- <f10> function key 10
+ will be executed at runtime because of the single quotes so that user_current_folder will always have the value of the currently opened folder.
- _\bk_\be_\by does not need to be enclosed in quotes unless it contains a space (`` '').
+ A more practical example is:
+folder-hook . 'source ~/.mutt/score-$muttng_folder_name'
- _\bf_\bu_\bn_\bc_\bt_\bi_\bo_\bn specifies which action to take when _\bk_\be_\by is pressed. For a complete
- list of functions, see the _\br_\be_\bf_\be_\br_\be_\bn_\bc_\be (section 7.5 , page 174). The special
- function noop unbinds the specified key sequence.
+ which can be used to source files containing score commands depending on the folder the user enters.
- _\b3_\b._\b6 _\bD_\be_\bf_\bi_\bn_\bi_\bn_\bg _\ba_\bl_\bi_\ba_\bs_\be_\bs _\bf_\bo_\br _\bc_\bh_\ba_\br_\ba_\bc_\bt_\be_\br _\bs_\be_\bt_\bs
+3.6. Type Conversions
- Usage: charset-hook _\ba_\bl_\bi_\ba_\bs _\bc_\bh_\ba_\br_\bs_\be_\bt
+ A note about variable's types during conversion: internally values are stored in internal types but for any dump/query or set operation they're converted to and from string. That means that there's no need to worry about types when referencing any variable. As an example, the following can be used without harm (besides makeing muttng very likely behave strange):
+set read_inc = 100
+set folder = $read_inc
+set read_inc = $folder
+set user_magic_number = 42
+set folder = $user_magic_number
- Usage: iconv-hook _\bc_\bh_\ba_\br_\bs_\be_\bt _\bl_\bo_\bc_\ba_\bl_\b-_\bc_\bh_\ba_\br_\bs_\be_\bt
+4. Defining/Using aliases
- The charset-hook command defines an alias for a character set. This is useful
- to properly display messages which are tagged with a character set name not
- known to mutt.
+ Usage: alias key address [ , address, ... ]
- The iconv-hook command defines a system-specific name for a character set.
- This is helpful when your systems character conversion library insists on using
- strange, system-specific names for character sets.
+ It's usually very cumbersome to remember or type out the address of someone you are communicating with. Mutt-ng allows you to create ``aliases'' which map a short string to a full address.
- _\b3_\b._\b7 _\bS_\be_\bt_\bt_\bi_\bn_\bg _\bv_\ba_\br_\bi_\ba_\bb_\bl_\be_\bs _\bb_\ba_\bs_\be_\bd _\bu_\bp_\bo_\bn _\bm_\ba_\bi_\bl_\bb_\bo_\bx
+ Note: if you want to create an alias for a group (by specifying more than one address), you must separate the addresses with a comma (``,'').
- Usage: folder-hook [!]_\br_\be_\bg_\be_\bx_\bp _\bc_\bo_\bm_\bm_\ba_\bn_\bd
+ To remove an alias or aliases (``*'' means all aliases):
- It is often desirable to change settings based on which mailbox you are
+ unalias [ * | key ... ]
+alias muttdude me@cs.hmc.edu (Michael Elkins)
+alias theguys manny, moe, jack
- The Mutt Next Generation E-Mail Client 29
+ Unlike other mailers, Mutt-ng doesn't require aliases to be defined in a special file. The alias command can appear anywhere in a configuration file, as long as this file is source. Consequently, you can have multiple alias files, or you can have all aliases defined in your muttrc.
- reading. The folder-hook command provides a method by which you can execute
- any configuration command. _\br_\be_\bg_\be_\bx_\bp is a regular expression specifying in which
- mailboxes to execute _\bc_\bo_\bm_\bm_\ba_\bn_\bd before loading. If a mailbox matches multiple
- folder-hook's, they are executed in the order given in the muttrc.
+ On the other hand, the create-alias function can use only one file, the one pointed to by the alias-file variable (which is ˜/.muttrc by default). This file is not special either, in the sense that Mutt-ng will happily append aliases to any file, but in order for the new aliases to take effect you need to explicitly source this file too.
- N\bNo\bot\bte\be:\b: if you use the ``!'' shortcut for _\b$_\bs_\bp_\bo_\bo_\bl_\bf_\bi_\bl_\be (section 7.4.304 , page
- 162) at the beginning of the pattern, you must place it inside of double or
- single quotes in order to distinguish it from the logical _\bn_\bo_\bt operator for the
- expression.
+ For example:
+source /usr/local/share/Mutt-ng.aliases
+source ~/.mail_aliases
+set alias_file=~/.mail_aliases
- Note that the settings are _\bn_\bo_\bt restored when you leave the mailbox. For exam-
- ple, a command action to perform is to change the sorting method based upon the
- mailbox being read:
+ To use aliases, you merely use the alias at any place in mutt where mutt prompts for addresses, such as the To: or Cc: prompt. You can also enter aliases in your editor at the appropriate headers if you have the edit-headers variable set.
- folder-hook mutt set sort=threads
+ In addition, at the various address prompts, you can use the tab character to expand a partial alias to the full alias. If there are multiple matches, mutt will bring up a menu with the matching aliases. In order to be presented with the full list of aliases, you must hit tab with out a partial alias, such as at the beginning of the prompt or after a comma denoting multiple addresses.
- However, the sorting method is not restored to its previous value when reading
- a different mailbox. To specify a _\bd_\be_\bf_\ba_\bu_\bl_\bt command, use the pattern ``.'':
+ In the alias menu, you can select as many aliases as you want with the select-entry key (default: RET), and use the exit key (default: q) to return to the address prompt.
- folder-hook . set sort=date-sent
+5. Changing the default key bindings
- _\b3_\b._\b8 _\bK_\be_\by_\bb_\bo_\ba_\br_\bd _\bm_\ba_\bc_\br_\bo_\bs
+ Usage: bind map key function
- Usage: macro _\bm_\be_\bn_\bu _\bk_\be_\by _\bs_\be_\bq_\bu_\be_\bn_\bc_\be [ _\bd_\be_\bs_\bc_\br_\bi_\bp_\bt_\bi_\bo_\bn ]
+ This command allows you to change the default key bindings (operation invoked when pressing a key).
- Macros are useful when you would like a single key to perform a series of
- actions. When you press _\bk_\be_\by in menu _\bm_\be_\bn_\bu, Mutt-ng will behave as if you had
- typed _\bs_\be_\bq_\bu_\be_\bn_\bc_\be. So if you have a common sequence of commands you type, you can
- create a macro to execute those commands with a single key.
+ map specifies in which menu the binding belongs. Multiple maps may be specified by separating them with commas (no additional whitespace is allowed). The currently defined maps are:
- _\bm_\be_\bn_\bu is the _\bm_\ba_\bp (section 3.5 , page 26) which the macro will be bound. Multi-
- ple maps may be specified by separating multiple menu arguments by commas.
- Whitespace may not be used in between the menu arguments and the commas sepa-
- rating them.
+ generic
+ This is not a real menu, but is used as a fallback for all of the other menus except for the pager and editor modes. If a key is not defined in another menu, Mutt-ng will look for a binding to use in this menu. This allows you to bind a key to a certain function in multiple menus instead of having multiple bind statements to accomplish the same task.
- _\bk_\be_\by and _\bs_\be_\bq_\bu_\be_\bn_\bc_\be are expanded by the same rules as the _\bk_\be_\by _\bb_\bi_\bn_\bd_\bi_\bn_\bg_\bs (section
- 3.5 , page 26). There are some additions however. The first is that control
- characters in _\bs_\be_\bq_\bu_\be_\bn_\bc_\be can also be specified as _\b^_\bx. In order to get a caret
- (`^'') you need to use _\b^_\b^. Secondly, to specify a certain key such as _\bu_\bp or to
- invoke a function directly, you can use the format _\b<_\bk_\be_\by _\bn_\ba_\bm_\be_\b> and _\b<_\bf_\bu_\bn_\bc_\bt_\bi_\bo_\bn
- _\bn_\ba_\bm_\be_\b>. For a listing of key names see the section on _\bk_\be_\by _\bb_\bi_\bn_\bd_\bi_\bn_\bg_\bs (section
- 3.5 , page 26). Functions are listed in the _\bf_\bu_\bn_\bc_\bt_\bi_\bo_\bn _\br_\be_\bf_\be_\br_\be_\bn_\bc_\be (section
- 7.5 , page 174).
+ alias
+ The alias menu is the list of your personal aliases as defined in your muttrc. It is the mapping from a short alias name to the full email address(es) of the recipient(s).
- The advantage with using function names directly is that the macros will work
- regardless of the current key bindings, so they are not dependent on the user
- having particular key definitions. This makes them more robust and portable,
- and also facilitates defining of macros in files used by more than one user
+ attach
+ The attachment menu is used to access the attachments on received messages.
- The Mutt Next Generation E-Mail Client 30
+ browser
+ The browser is used for both browsing the local directory structure, and for listing all of your incoming mailboxes.
- (eg. the system Muttngrc).

+ The editor is the line-based editor the user enters text data.
- Optionally you can specify a descriptive text after _\bs_\be_\bq_\bu_\be_\bn_\bc_\be, which is shown in
- the help screens.
+ index
+ The index is the list of messages contained in a mailbox.
- N\bNo\bot\bte\be:\b: Macro definitions (if any) listed in the help screen(s), are silently
- truncated at the screen width, and are not wrapped.

+ pager
+ The pager is the mode used to display message/attachment data, and help listings.
- Usage: color _\bo_\bb_\bj_\be_\bc_\bt _\bf_\bo_\br_\be_\bg_\br_\bo_\bu_\bn_\bd _\bb_\ba_\bc_\bk_\bg_\br_\bo_\bu_\bn_\bd [ _\br_\be_\bg_\be_\bx_\bp ]
+ pgp
+ The pgp menu is used to select the OpenPGP keys used for encrypting outgoing messages.
- Usage: color index _\bf_\bo_\br_\be_\bg_\br_\bo_\bu_\bn_\bd _\bb_\ba_\bc_\bk_\bg_\br_\bo_\bu_\bn_\bd _\bp_\ba_\bt_\bt_\be_\br_\bn
+ postpone
+ The postpone menu is similar to the index menu, except is used when recalling a message the user was composing, but saved until later.
- Usage: uncolor index _\bp_\ba_\bt_\bt_\be_\br_\bn [ _\bp_\ba_\bt_\bt_\be_\br_\bn ... ]
+ key is the key (or key sequence) you wish to bind. To specify a control character, use the sequence \Cx, where x is the letter of the control character (for example, to specify control-A use ``\Ca''). Note that the case of x as well as \C is ignored, so that \CA, \Ca, \cA and \ca are all equivalent. An alternative form is to specify the key as a three digit octal number prefixed with a ``\'' (for example \177 is equivalent to \c?).
- If your terminal supports color, you can spice up Mutt-ng by creating your own
- color scheme. To define the color of an object (type of information), you must
- specify both a foreground color a\ban\bnd\bd a background color (it is not possible to
- only specify one or the other).
+ In addition, key may consist of:
+\t tab
+<tab> tab
+<backtab> backtab / shift-tab

+6. Defining aliases for character sets
- +\bo bold (highlighting bold patterns in the body of messages)
+ Usage: charset-hook alias charset Usage: iconv-hook charset local-charset
- +\bo error (error messages printed by Mutt-ng)
+ The charset-hook command defines an alias for a character set. This is useful to properly display messages which are tagged with a character set name not known to mutt.
- +\bo header (match _\br_\be_\bg_\be_\bx_\bp in the message header)
+ The iconv-hook command defines a system-specific name for a character set. This is helpful when your systems character conversion library insists on using strange, system-specific names for character sets.
- +\bo hdrdefault (default color of the message header in the pager)
+7. Setting variables based upon mailbox
- +\bo index (match _\bp_\ba_\bt_\bt_\be_\br_\bn in the message index)
+ Usage: folder-hook [!]regexp command
- +\bo indicator (arrow or bar used to indicate the current item in a menu)
+ It is often desirable to change settings based on which mailbox you are reading. The folder-hook command provides a method by which you can execute any configuration command. regexp is a regular expression specifying in which mailboxes to execute command before loading. If a mailbox matches multiple folder-hook's, they are executed in the order given in the muttrc.
- +\bo markers (the ``+'' markers at the beginning of wrapped lines in the pager)
+ Note: if you use the ``!'' shortcut for spoolfile at the beginning of the pattern, you must place it inside of double or single quotes in order to distinguish it from the logical not operator for the expression.
- +\bo message (informational messages)
+ Note that the settings are not restored when you leave the mailbox. For example, a command action to perform is to change the sorting method based upon the mailbox being read:
+folder-hook mutt set sort=threads
- +\bo normal
+ However, the sorting method is not restored to its previous value when reading a different mailbox. To specify a default command, use the pattern ``.'':
+folder-hook . set sort=date-sent
- +\bo quoted (text matching _\b$_\bq_\bu_\bo_\bt_\be_\b__\br_\be_\bg_\be_\bx_\bp (section 7.4.232 , page 145) in the
- body of a message)
+8. Keyboard macros
- +\bo quoted1, quoted2, ..., quotedN\bN (higher levels of quoting)
+ Usage: macro menu key sequence [ description ]
- +\bo search (highlighting of words in the pager)
+ Macros are useful when you would like a single key to perform a series of actions. When you press key in menu menu, Mutt-ng will behave as if you had typed sequence. So if you have a common sequence of commands you type, you can create a macro to execute those commands with a single key.
- The Mutt Next Generation E-Mail Client 31
+ menu is the maps which the macro will be bound. Multiple maps may be specified by separating multiple menu arguments by commas. Whitespace may not be used in between the menu arguments and the commas separating them.
- +\bo signature
+ key and sequence are expanded by the same rules as the bind. There are some additions however. The first is that control characters in sequence can also be specified as ^x. In order to get a caret (`^'') you need to use ^^. Secondly, to specify a certain key such as up or to invoke a function directly, you can use the format <key name> and <function name>. For a listing of key names see the section on bind. Functions are listed in the functions.
- +\bo status (mode lines used to display info about the mailbox or message)
+ The advantage with using function names directly is that the macros will work regardless of the current key bindings, so they are not dependent on the user having particular key definitions. This makes them more robust and portable, and also facilitates defining of macros in files used by more than one user (eg. the system Muttngrc).
- +\bo tilde (the ``~'' used to pad blank lines in the pager)
+ Optionally you can specify a descriptive text after sequence, which is shown in the help screens.
- +\bo tree (thread tree drawn in the message index and attachment menu)
+ Note: Macro definitions (if any) listed in the help screen(s), are silently truncated at the screen width, and are not wrapped.
- +\bo underline (highlighting underlined patterns in the body of messages)
+9. Using color and mono video attributes
- _\bf_\bo_\br_\be_\bg_\br_\bo_\bu_\bn_\bd and _\bb_\ba_\bc_\bk_\bg_\br_\bo_\bu_\bn_\bd can be one of the following:
+ Usage: color object foreground background [ regexp ] Usage: color index foreground background pattern Usage: uncolor index pattern [ pattern ... ]
- +\bo white
+ If your terminal supports color, you can spice up Mutt-ng by creating your own color scheme. To define the color of an object (type of information), you must specify both a foreground color and a background color (it is not possible to only specify one or the other).

+12.1. Introduction
- +\bo standout
+ Mutt-ng contains support for so-called format=flowed messages. In the beginning of email, each message had a fixed line width, and it was enough for displaying them on fixed-size terminals. But times changed, and nowadays hardly anybody still uses fixed-size terminals: more people nowaydays use graphical user interfaces, with dynamically resizable windows. This led to the demand of a new email format that makes it possible for the email client to make the email look nice in a resizable window without breaking quoting levels and creating an incompatible email format that can also be displayed nicely on old fixed-size terminals.

- Usage: [un]ignore _\bp_\ba_\bt_\bt_\be_\br_\bn [ _\bp_\ba_\bt_\bt_\be_\br_\bn ... ]
+12.2. Receiving: Display Setup
- Messages often have many header fields added by automatic processing systems,
- or which may not seem useful to display on the screen. This command allows you
- to specify header fields which you don't normally want to see.
+ When you receive emails that are marked as format=flowed messages, and is formatted correctly, mutt-ng will try to reformat the message to optimally fit on your terminal. If you want a fixed margin on the right side of your terminal, you can set the following:
+ set wrapmargin = 10
- You do not need to specify the full header field name. For example, ``ignore
- content-'' will ignore all header fields that begin with the pattern ``con-
- tent-''. ``ignore *'' will ignore all headers.
+ The code above makes the line break 10 columns before the right side of the terminal.
- To remove a previously added token from the list, use the ``unignore'' command.
- The ``unignore'' command will make Mutt-ng display headers with the given pat-
- tern. For example, if you do ``ignore x-'' it is possible to ``unignore x-
- mailer''.
+ If your terminal is so wide that the lines are embarrassingly long, you can also set a maximum line length:
+ set max_line_length = 120
- ``unignore *'' will remove all tokens from the ignore list.
+ The example above will give you lines not longer than 120 characters.
- For example:
+ When you view at format=flowed messages, you will often see the quoting hierarchy like in the following example:
+ >Bill, can you please send last month's progress report to Mr.
+ >Morgan? We also urgently need the cost estimation for the new
+ >production server that we want to set up before our customer's
+ >project will go live.
- # Sven's draconian header weeding
- ignore *
- unignore from date subject to cc
- unignore organization organisation x-mailer: x-newsreader: x-mailing-list:
- unignore posted-to:
+ This obviously doesn't look very nice, and it makes it very hard to differentiate between text and quoting character. The solution is to configure mutt-ng to "stuff" the quoting:
+ set stuff_quoted
- The Mutt Next Generation E-Mail Client 33
+ This will lead to a nicer result that is easier to read:
+ > Bill, can you please send last month's progress report to Mr.
+ > Morgan? We also urgently need the cost estimation for the new
+ > production server that we want to set up before our customer's
+ > project will go live.

+12.3. Sending
- Usage: [un]alternates _\br_\be_\bg_\be_\bx_\bp [ _\br_\be_\bg_\be_\bx_\bp ... ]
+ If you want mutt-ng to send emails with format=flowed set, you need to explicitly set it:
+ set text_flowed
- With various functions, mutt will treat messages differently, depending on
- whether you sent them or whether you received them from someone else. For
- instance, when replying to a message that you sent to a different party, mutt
- will automatically suggest to send the response to the original message's
- recipients -- responding to yourself won't make much sense in many cases. (See
- _\b$_\br_\be_\bp_\bl_\by_\b__\bt_\bo (section 7.4.240 , page 147).)
+ Additionally, you have to use an editor which supports writing format=flowed-conforming emails. For vim, this is done by adding w to the formatoptions (see :h formatoptions and :h fo-table) when writing emails.
- Many users receive e-mail under a number of different addresses. To fully use
- mutt's features here, the program must be able to recognize what e-mail
- addresses you receive mail under. That's the purpose of the alternates command:
- It takes a list of regular expressions, each of which can identify an address
- under which you receive e-mail.
+ Also note that format=flowed knows about ``space-stuffing'', that is, when sending messages, some kinds of lines have to be indented with a single space on the sending side. On the receiving side, the first space (if any) is removed. As a consequence and in addition to the above simple setting, please keep this in mind when making manual formattings within the editor. Also note that mutt-ng currently violates the standard (RfC 3676) as it does not space-stuff lines starting with:
+ * > This is not the quote character but a right angle used for other reasons
+ * From with a trailing space.
+ * just a space for formatting reasons
- The unalternates command can be used to write exceptions to alternates pat-
- terns. If an address matches something in an alternates command, but you none-
- theless do not think it is from you, you can list a more precise pattern under
- an unalternates command.
+ Please make sure that you manually prepend a space to each of them.
- To remove a regular expression from the alternates list, use the unalternates
- command with exactly the same _\br_\be_\bg_\be_\bx_\bp. Likewise, if the _\br_\be_\bg_\be_\bx_\bp for a alternates
- command matches an entry on the unalternates list, that unalternates entry will
- be removed. If the _\br_\be_\bg_\be_\bx_\bp for unalternates is ``*'', _\ba_\bl_\bl _\be_\bn_\bt_\br_\bi_\be_\bs on alternates
- will be removed.
+12.4. Additional Notes
- _\b3_\b._\b1_\b2 _\bF_\bo_\br_\bm_\ba_\bt _\b= _\bF_\bl_\bo_\bw_\be_\bd
+ For completeness, the delete-space variable provides the mechanism to generate a DelSp=yes parameter on outgoing messages. According to the standard, clients receiving a format=flowed messages should delete the last space of a flowed line but still interpret the line as flowed. Because flowed lines usually contain only one space at the end, this parameter would make the receiving client concatenate the last word of the previous with the first of the current line without a space. This makes ordinary text unreadable and is intended for languages rarely using spaces. So please use this setting only if you're sure what you're doing.

+13. Mailing lists
- Mutt-ng contains support for so-called format=flowed messages. In the begin-
- ning of email, each message had a fixed line width, and it was enough for dis-
- playing them on fixed-size terminals. But times changed, and nowadays hardly
- anybody still uses fixed-size terminals: more people nowaydays use graphical
- user interfaces, with dynamically resizable windows. This led to the demand of
- a new email format that makes it possible for the email client to make the
- email look nice in a resizable window without breaking quoting levels and cre-
- ating an incompatible email format that can also be displayed nicely on old
- fixed-size terminals.
+ Usage: [un]lists regexp [ regexp ... ] Usage: [un]subscribe regexp [ regexp ... ]
- For introductory information on format=flowed messages, see
- <http://www.joeclark.org/ffaq.html>.
+ Mutt-ng has a few nice features for using-lists. In order to take advantage of them, you must specify which addresses belong to mailing lists, and which mailing lists you are subscribed to. Once you have done this, the list-reply function will work for all known lists. Additionally, when you send a message to a subscribed list, mutt will add a Mail-Followup-To header to tell other users' mail user agents not to send copies of replies to your personal address. Note that the Mail-Followup-To header is a non-standard extension which is not supported by all mail user agents. Adding it is not bullet-proof against receiving personal CCs of list messages. Also note that the generation of the Mail-Followup-To header is controlled by the followup-to configuration variable.
- _\b3_\b._\b1_\b2_\b._\b2 _\bR_\be_\bc_\be_\bi_\bv_\bi_\bn_\bg_\b: _\bD_\bi_\bs_\bp_\bl_\ba_\by _\bS_\be_\bt_\bu_\bp
+ More precisely, Mutt-ng maintains lists of patterns for the addresses of known and subscribed mailing lists. Every subscribed mailing list is known. To mark a mailing list as known, use the ``lists'' command. To mark it as subscribed, use ``subscribe''.
- When you receive emails that are marked as format=flowed messages, and is for-
- matted correctly, mutt-ng will try to reformat the message to optimally fit on
- your terminal. If you want a fixed margin on the right side of your terminal,
- you can set the following:
+ You can use regular expressions with both commands. To mark all messages sent to a specific bug report's address on mutt's bug tracking system as list mail, for instance, you could say ``subscribe [0-9]*@bugs.guug.de''. Often, it's sufficient to just give a portion of the list's e-mail address.
- The Mutt Next Generation E-Mail Client 34
+ Specify as much of the address as you need to to remove ambiguity. For example, if you've subscribed to the Mutt-ng mailing list, you will receive mail addressed to mutt-users@mutt.org. So, to tell Mutt-ng that this is a mailing list, you could add ``lists mutt-users'' to your initialization file. To tell mutt that you are subscribed to it, add ``subscribe mutt-users'' to your initialization file instead. If you also happen to get mail from someone whose address is mutt-users@example.com, you could use ``lists mutt-users@mutt\\.org'' or ``subscribe mutt-users@mutt\\.org'' to match only mail from the actual list.
- set wrapmargin = 10
+ The ``unlists'' command is used to remove a token from the list of known and subscribed mailing-lists. Use ``unlists *'' to remove all tokens.
- The code above makes the line break 10 columns before the right side of the
- terminal.
+ To remove a mailing list from the list of subscribed mailing lists, but keep it on the list of known mailing lists, use ``unsubscribe''.
- If your terminal is so wide that the lines are embarrassingly long, you can
- also set a maximum line length:
+14. Using Multiple spool mailboxes
- set max_line_length = 120
+ Usage: mbox-hook [!]pattern mailbox
- The example above will give you lines not longer than 120 characters.
+ This command is used to move read messages from a specified mailbox to a different mailbox automatically when you quit or change folders. pattern is a regular expression specifying the mailbox to treat as a ``spool'' mailbox and mailbox specifies where mail should be saved when read.
- When you view at format=flowed messages, you will often see the quoting hierar-
- chy like in the following example:
+ Unlike some of the other hook commands, only the first matching pattern is used (it is not possible to save read mail in more than a single mailbox).
- >Bill, can you please send last month's progress report to Mr.
- >Morgan? We also urgently need the cost estimation for the new
- >production server that we want to set up before our customer's
- >project will go live.
+15. Defining mailboxes which receive mail
- This obviously doesn't look very nice, and it makes it very hard to differenti-
- ate between text and quoting character. The solution is to configure mutt-ng to
- "stuff" the quoting:
+ Usage: [un]mailboxes [!]filename [ filename ... ]
- set stuff_quoted
+ This command specifies folders which can receive mail and which will be checked for new messages. By default, the main menu status bar displays how many of these folders have new messages.
- This will lead to a nicer result that is easier to read:
+ When changing folders, pressing space will cycle through folders with new mail.
- > Bill, can you please send last month's progress report to Mr.
- > Morgan? We also urgently need the cost estimation for the new
- > production server that we want to set up before our customer's
- > project will go live.
+ Pressing TAB in the directory browser will bring up a menu showing the files specified by the mailboxes command, and indicate which contain new messages. Mutt-ng will automatically enter this mode when invoked from the command line with the -y option.
- _\b3_\b._\b1_\b2_\b._\b3 _\bS_\be_\bn_\bd_\bi_\bn_\bg
+ The ``unmailboxes'' command is used to remove a token from the list of folders which receive mail. Use ``unmailboxes *'' to remove all tokens.
- If you want mutt-ng to send emails with format=flowed set, you need to explic-
- itly set it:
+ Note: new mail is detected by comparing the last modification time to the last access time. Utilities like biff or frm or any other program which accesses the mailbox might cause Mutt-ng to never detect new mail for that mailbox if they do not properly reset the access time. Backup tools are another common reason for updated access times.
- set text_flowed
+ Note: the filenames in the mailboxes command are resolved when the command is executed, so if these names contain shortcuts (such as ``='' and ``!''), any variable definition that affect these characters (like folder and spoolfile) should be executed before the mailboxes command.
- The Mutt Next Generation E-Mail Client 35
+16. User defined headers
- Additionally, you have to use an editor which supports writing format=flowed-
- conforming emails. For vim, this is done by adding w to the formatoptions (see
- :h formatoptions and :h fo-table) when writing emails.
+ Usage: my_hdr string unmy_hdr field [ field ... ]
- Also note that _\bf_\bo_\br_\bm_\ba_\bt_\b=_\bf_\bl_\bo_\bw_\be_\bd knows about ``space-stuffing'', that is, when
- sending messages, some kinds of lines have to be indented with a single space
- on the sending side. On the receiving side, the first space (if any) is
- removed. As a consequence and in addition to the above simple setting, please
- keep this in mind when making manual formattings within the editor. Also note
- that mutt-ng currently violates the standard (RfC 3676) as it does not space-
- stuff lines starting with:
+ The ``my_hdr'' command allows you to create your own header fields which will be added to every message you send.
- +\bo > This is _\bn_\bo_\bt the quote character but a right angle used for other reasons
+ For example, if you would like to add an ``Organization:'' header field to all of your outgoing messages, you can put the command
+my_hdr Organization: A Really Big Company, Anytown, USA
- +\bo From with a trailing space.
+ in your .muttrc.
- +\bo just a space for formatting reasons
+ Note: space characters are not allowed between the keyword and the colon (``:''). The standard for electronic mail (RFC822) says that space is illegal there, so Mutt-ng enforces the rule.
- Please make sure that you manually prepend a space to each of them.
+ If you would like to add a header field to a single message, you should either set the edit-headers variable, or use the edit-headers function (default: ``E'') in the send-menu so that you can edit the header of your message along with the body.
- _\b3_\b._\b1_\b2_\b._\b4 _\bA_\bd_\bd_\bi_\bt_\bi_\bo_\bn_\ba_\bl _\bN_\bo_\bt_\be_\bs
+ To remove user defined header fields, use the ``unmy_hdr'' command. You may specify an asterisk (``*'') to remove all header fields, or the fields to remove. For example, to remove all ``To'' and ``Cc'' header fields, you could use:
+unmy_hdr to cc
- "
+17. Defining the order of headers when viewing messages
- For completeness, the _\b$_\bd_\be_\bl_\be_\bt_\be_\b__\bs_\bp_\ba_\bc_\be (section 7.4.51 , page 100) variable pro-
- vides the mechanism to generate a DelSp=yes parameter on _\bo_\bu_\bt_\bg_\bo_\bi_\bn_\bg messages.
- According to the standard, clients receiving a format=flowed messages should
- delete the last space of a flowed line but still interpret the line as flowed.
- Because flowed lines usually contain only one space at the end, this parameter
- would make the receiving client concatenate the last word of the previous with
- the first of the current line _\bw_\bi_\bt_\bh_\bo_\bu_\bt a space. This makes ordinary text unread-
- able and is intended for languages rarely using spaces. So please use this set-
- ting only if you're sure what you're doing.
+ Usage: hdr_order header1 header2 header3
- _\b3_\b._\b1_\b3 _\bM_\ba_\bi_\bl_\bi_\bn_\bg _\bl_\bi_\bs_\bt_\bs
+ With this command, you can specify an order in which mutt will attempt to present headers to you when viewing messages.
- Usage: [un]lists _\br_\be_\bg_\be_\bx_\bp [ _\br_\be_\bg_\be_\bx_\bp ... ]
+ ``unhdr_order *'' will clear all previous headers from the order list, thus removing the header order effects set by the system-wide startup file.
+hdr_order From Date: From: To: Cc: Subject:
- Usage: [un]subscribe _\br_\be_\bg_\be_\bx_\bp [ _\br_\be_\bg_\be_\bx_\bp ... ]
+18. Specify default save filename
- Mutt-ng has a few nice features for _\bh_\ba_\bn_\bd_\bl_\bi_\bn_\bg _\bm_\ba_\bi_\bl_\bi_\bn_\bg _\bl_\bi_\bs_\bt_\bs (section 4.10 ,
- page 60). In order to take advantage of them, you must specify which addresses
- belong to mailing lists, and which mailing lists you are subscribed to. Once
- you have done this, the _\bl_\bi_\bs_\bt_\b-_\br_\be_\bp_\bl_\by (section 2.5.4 , page 12) function will
- work for all known lists. Additionally, when you send a message to a sub-
- scribed list, mutt will add a Mail-Followup-To header to tell other users' mail
- user agents not to send copies of replies to your personal address. Note that
- the Mail-Followup-To header is a non-standard extension which is not supported
- by all mail user agents. Adding it is not bullet-proof against receiving per-
- sonal CCs of list messages. Also note that the generation of the Mail-Fol-
- lowup-To header is controlled by the _\b$_\bf_\bo_\bl_\bl_\bo_\bw_\bu_\bp_\b__\bt_\bo (section 7.4.72 , page 105)
- configuration variable.
+ Usage: save-hook [!]pattern filename
- The Mutt Next Generation E-Mail Client 36
+ This command is used to override the default filename used when saving messages. filename will be used as the default filename if the message is From: an address matching regexp or if you are the author and the message is addressed to: something matching regexp.
- More precisely, Mutt-ng maintains lists of patterns for the addresses of known
- and subscribed mailing lists. Every subscribed mailing list is known. To mark
- a mailing list as known, use the ``lists'' command. To mark it as subscribed,
- use ``subscribe''.
+ See pattern-hook for information on the exact format of pattern.
- You can use regular expressions with both commands. To mark all messages sent
- to a specific bug report's address on mutt's bug tracking system as list mail,
- for instance, you could say ``subscribe [0-9]*@bugs.guug.de''. Often, it's
- sufficient to just give a portion of the list's e-mail address.
+ Examples:
+save-hook me@(turing\\.)?cs\\.hmc\\.edu$ +elkins
+save-hook aol\\.com$ +spam
- Specify as much of the address as you need to to remove ambiguity. For exam-
- ple, if you've subscribed to the Mutt-ng mailing list, you will receive mail
- addressed to _\bm_\bu_\bt_\bt_\b-_\bu_\bs_\be_\br_\bs_\b@_\bm_\bu_\bt_\bt_\b._\bo_\br_\bg. So, to tell Mutt-ng that this is a mailing
- list, you could add ``lists mutt-users'' to your initialization file. To tell
- mutt that you are subscribed to it, add ``subscribe mutt-users'' to your ini-
- tialization file instead. If you also happen to get mail from someone whose
- address is _\bm_\bu_\bt_\bt_\b-_\bu_\bs_\be_\br_\bs_\b@_\be_\bx_\ba_\bm_\bp_\bl_\be_\b._\bc_\bo_\bm, you could use ``lists mutt-
- users@mutt\\.org'' or ``subscribe mutt-users@mutt\\.org'' to match only mail
- from the actual list.
+ Also see the fcc-save-hook command.
- The ``unlists'' command is used to remove a token from the list of known and
- subscribed mailing-lists. Use ``unlists *'' to remove all tokens.
+19. Specify default Fcc: mailbox when composing
- To remove a mailing list from the list of subscribed mailing lists, but keep it
- on the list of known mailing lists, use ``unsubscribe''.
+ Usage: fcc-hook [!]pattern mailbox
- _\b3_\b._\b1_\b4 _\bU_\bs_\bi_\bn_\bg _\bM_\bu_\bl_\bt_\bi_\bp_\bl_\be _\bs_\bp_\bo_\bo_\bl _\bm_\ba_\bi_\bl_\bb_\bo_\bx_\be_\bs
+ This command is used to save outgoing mail in a mailbox other than record. Mutt-ng searches the initial list of message recipients for the first matching regexp and uses mailbox as the default Fcc: mailbox. If no match is found the message will be saved to record mailbox.
- Usage: mbox-hook [!]_\bp_\ba_\bt_\bt_\be_\br_\bn _\bm_\ba_\bi_\bl_\bb_\bo_\bx
+ See pattern-hook for information on the exact format of pattern.
- This command is used to move read messages from a specified mailbox to a dif-
- ferent mailbox automatically when you quit or change folders. _\bp_\ba_\bt_\bt_\be_\br_\bn is a
- regular expression specifying the mailbox to treat as a ``spool'' mailbox and
- _\bm_\ba_\bi_\bl_\bb_\bo_\bx specifies where mail should be saved when read.
+ Example: fcc-hook [@.]aol\\.com$ +spammers
- Unlike some of the other _\bh_\bo_\bo_\bk commands, only the _\bf_\bi_\br_\bs_\bt matching pattern is used
- (it is not possible to save read mail in more than a single mailbox).

+20. Specify default save filename and default Fcc: mailbox at once
- Usage: [un]mailboxes [!]_\bf_\bi_\bl_\be_\bn_\ba_\bm_\be [ _\bf_\bi_\bl_\be_\bn_\ba_\bm_\be ... ]
+ Usage: fcc-save-hook [!]pattern mailbox
- This command specifies folders which can receive mail and which will be checked
- for new messages. By default, the main menu status bar displays how many of
- these folders have new messages.
+ This command is a shortcut, equivalent to doing both a fcc-hook and a save-hook with its arguments.
- When changing folders, pressing _\bs_\bp_\ba_\bc_\be will cycle through folders with new mail.
+21. Change settings based upon message recipients
- Pressing TAB in the directory browser will bring up a menu showing the files
- specified by the mailboxes command, and indicate which contain new messages.
+ Usage: reply-hook [!]pattern command Usage: send-hook [!]pattern command Usage: send2-hook [!]pattern command
- The Mutt Next Generation E-Mail Client 37
+ These commands can be used to execute arbitrary configuration commands based upon recipients of the message. pattern is a regular expression matching the desired address. command is executed when regexp matches recipients of the message.
- Mutt-ng will automatically enter this mode when invoked from the command line
- with the -y option.
+ reply-hook is matched against the message you are replying to, instead of the message you are sending. send-hook is matched against all messages, both new and replies. Note: reply-hooks are matched before the send-hook, regardless of the order specified in the users's configuration file.
- The ``unmailboxes'' command is used to remove a token from the list of folders
- which receive mail. Use ``unmailboxes *'' to remove all tokens.
+ send2-hook is matched every time a message is changed, either by editing it, or by using the compose menu to change its recipients or subject. send2-hook is executed after send-hook, and can, e.g., be used to set parameters such as the sendmail variable depending on the message's sender address.
- N\bNo\bot\bte\be:\b: new mail is detected by comparing the last modification time to the last
- access time. Utilities like biff or frm or any other program which accesses
- the mailbox might cause Mutt-ng to never detect new mail for that mailbox if
- they do not properly reset the access time. Backup tools are another common
- reason for updated access times.
+ For each type of send-hook or reply-hook, when multiple matches occur, commands are executed in the order they are specified in the muttrc (for that type of hook).
- N\bNo\bot\bte\be:\b: the filenames in the mailboxes command are resolved when the command is
- executed, so if these names contain _\bs_\bh_\bo_\br_\bt_\bc_\bu_\bt _\bc_\bh_\ba_\br_\ba_\bc_\bt_\be_\br_\bs (section 4.9 , page
- 60) (such as ``='' and ``!''), any variable definition that affect these char-
- acters (like _\b$_\bf_\bo_\bl_\bd_\be_\br (section 7.4.70 , page 104) and _\b$_\bs_\bp_\bo_\bo_\bl_\bf_\bi_\bl_\be (section
- 7.4.304 , page 162)) should be executed before the mailboxes command.
+ See pattern-hook for information on the exact format of pattern.
- _\b3_\b._\b1_\b6 _\bU_\bs_\be_\br _\bd_\be_\bf_\bi_\bn_\be_\bd _\bh_\be_\ba_\bd_\be_\br_\bs
+ Example: send-hook mutt "set mime_forward signature=''"
- Usage:
+ Another typical use for this command is to change the values of the attribution, signature and locale variables in order to change the language of the attributions and signatures based upon the recipients.
- my_hdr _\bs_\bt_\br_\bi_\bn_\bg
+ Note: the send-hook's are only executed ONCE after getting the initial list of recipients. Adding a recipient after replying or editing the message will NOT cause any send-hook to be executed. Also note that my_hdr commands which modify recipient headers, or the message's subject, don't have any effect on the current message when executed from a send-hook.
- unmy_hdr _\bf_\bi_\be_\bl_\bd [ _\bf_\bi_\be_\bl_\bd ... ]
+22. Change settings before formatting a message
- The ``my_hdr'' command allows you to create your own header fields which will
- be added to every message you send.
+ Usage: message-hook [!]pattern command
- For example, if you would like to add an ``Organization:'' header field to all
- of your outgoing messages, you can put the command
+ This command can be used to execute arbitrary configuration commands before viewing or formatting a message based upon information about the message. command is executed if the pattern matches the message to be displayed. When multiple matches occur, commands are executed in the order they are specified in the muttrc.
- my_hdr Organization: A Really Big Company, Anytown, USA
+ See pattern-hook for information on the exact format of pattern.
- in your .muttrc.
+ Example:
+message-hook ~A 'set pager=builtin'
+message-hook '~f freshmeat-news' 'set pager="less \"+/^ subject: .*\""'
- N\bNo\bot\bte\be:\b: space characters are _\bn_\bo_\bt allowed between the keyword and the colon
- (``:''). The standard for electronic mail (RFC822) says that space is illegal
- there, so Mutt-ng enforces the rule.
+23. Choosing the cryptographic key of the recipient
- If you would like to add a header field to a single message, you should either
- set the _\be_\bd_\bi_\bt_\b__\bh_\be_\ba_\bd_\be_\br_\bs (section 7.4.59 , page 102) variable, or use the _\be_\bd_\bi_\bt_\b-
- _\bh_\be_\ba_\bd_\be_\br_\bs function (default: ``E'') in the send-menu so that you can edit the
- header of your message along with the body.
+ Usage: crypt-hook pattern keyid
- To remove user defined header fields, use the ``unmy_hdr'' command. You may
- specify an asterisk (``*'') to remove all header fields, or the fields to
- remove. For example, to remove all ``To'' and ``Cc'' header fields, you could
- use:
+ When encrypting messages with PGP or OpenSSL, you may want to associate a certain key with a given e-mail address automatically, either because the recipient's public key can't be deduced from the destination address, or because, for some reasons, you need to override the key Mutt-ng would normally use. The crypt-hook command provides a method by which you can specify the ID of the public key to be used when encrypting messages to a certain recipient.
- The Mutt Next Generation E-Mail Client 38
+ The meaning of "key id" is to be taken broadly in this context: You can either put a numerical key ID here, an e-mail address, or even just a real name.

- _\b3_\b._\b1_\b7 _\bD_\be_\bf_\bi_\bn_\bi_\bn_\bg _\bt_\bh_\be _\bo_\br_\bd_\be_\br _\bo_\bf _\bh_\be_\ba_\bd_\be_\br_\bs _\bw_\bh_\be_\bn _\bv_\bi_\be_\bw_\bi_\bn_\bg _\bm_\be_\bs_\bs_\ba_\bg_\be_\bs
+ Usage: push string
- Usage: hdr_order _\bh_\be_\ba_\bd_\be_\br_\b1 _\bh_\be_\ba_\bd_\be_\br_\b2 _\bh_\be_\ba_\bd_\be_\br_\b3
+ This command adds the named string to the keyboard buffer. The string may contain control characters, key names and function names like the sequence string in the macro command. You may use it to automatically run a sequence of commands at startup, or when entering certain folders.
- With this command, you can specify an order in which mutt will attempt to
- present headers to you when viewing messages.
+25. Executing functions
- ``unhdr_order *'' will clear all previous headers from the order list, thus
- removing the header order effects set by the system-wide startup file.
+ Usage: exec function [ function ... ]
- hdr_order From Date: From: To: Cc: Subject:
+ This command can be used to execute any function. Functions are listed in the functions. ``exec function'' is equivalent to ``push <function>''.

+26. Message Scoring
- Usage: save-hook [!]_\bp_\ba_\bt_\bt_\be_\br_\bn _\bf_\bi_\bl_\be_\bn_\ba_\bm_\be
+ Usage: score pattern value Usage: unscore pattern [ pattern ... ]
- This command is used to override the default filename used when saving mes-
- sages. _\bf_\bi_\bl_\be_\bn_\ba_\bm_\be will be used as the default filename if the message is _\bF_\br_\bo_\bm_\b:
- an address matching _\br_\be_\bg_\be_\bx_\bp or if you are the author and the message is
- addressed _\bt_\bo_\b: something matching _\br_\be_\bg_\be_\bx_\bp.
+ In situations where you have to cope with a lot of emails, e.g. when you read many different mailing lists, and take part in discussions, it is always useful to have the important messages marked and the annoying messages or the ones that you aren't interested in deleted. For this purpose, mutt-ng features a mechanism called ``scoring''.
- See _\bM_\be_\bs_\bs_\ba_\bg_\be _\bM_\ba_\bt_\bc_\bh_\bi_\bn_\bg _\bi_\bn _\bH_\bo_\bo_\bk_\bs (section 4.5.1 , page 57) for information on the
- exact format of _\bp_\ba_\bt_\bt_\be_\br_\bn.
+ When you use scoring, every message has a base score of 0. You can then use the score command to define patterns and a positive or negative value associated with it. When a pattern matches a message, the message's score will be raised or lowered by the amount of the value associated with the pattern.
+score "~f nion@muttng\.org" 50
+score "~f @sco\.com" -100
- Examples:
+ If the pattern matches, it is also possible to set the score value of the current message to a certain value and then stop evaluation:
+score "~f santaclaus@northpole\.int" =666
- save-hook me@(turing\\.)?cs\\.hmc\\.edu$ +elkins
- save-hook aol\\.com$ +spam
+ What is important to note is that negative score values will be rounded up to 0.
- Also see the _\bf_\bc_\bc_\b-_\bs_\ba_\bv_\be_\b-_\bh_\bo_\bo_\bk (section 3.20 , page 39) command.
+ To make scoring actually useful, the score must be applied in some way. That's what the score thresholds are for. Currently, there are three score thresholds:
+ * flag threshold: when a message has a score value equal or higher than the flag threshold, it will be flagged.
+ * read threshold: when a message has a score value equal or lower than the read threshold, it will be marked as read.
+ * delete threshold: when a message has a score value equal or lower than the delete threshold, it will be marked as deleted.
- _\b3_\b._\b1_\b9 _\bS_\bp_\be_\bc_\bi_\bf_\by _\bd_\be_\bf_\ba_\bu_\bl_\bt _\bF_\bc_\bc_\b: _\bm_\ba_\bi_\bl_\bb_\bo_\bx _\bw_\bh_\be_\bn _\bc_\bo_\bm_\bp_\bo_\bs_\bi_\bn_\bg
+ These three thresholds can be set via the variables score-threshold-flag, score-threshold-read, score-threshold-delete and. By default, score-threshold-read and score-threshold-delete are set to -1, which means that in the default threshold configuration no message will ever get marked as read or deleted.
- Usage: fcc-hook [!]_\bp_\ba_\bt_\bt_\be_\br_\bn _\bm_\ba_\bi_\bl_\bb_\bo_\bx
+ Scoring gets especially interesting when combined with the color command and the ˜n pattern:
+color index black yellow "~n 10-"
+color index red yellow "~n 100-"
- This command is used to save outgoing mail in a mailbox other than _\b$_\br_\be_\bc_\bo_\br_\bd
- (section 7.4.237 , page 146). Mutt-ng searches the initial list of message
- recipients for the first matching _\br_\be_\bg_\be_\bx_\bp and uses _\bm_\ba_\bi_\bl_\bb_\bo_\bx as the default Fcc:
- mailbox. If no match is found the message will be saved to _\b$_\br_\be_\bc_\bo_\br_\bd (section
- 7.4.237 , page 146) mailbox.
+ The rules above mark all messages with a score between 10 and 99 with black and yellow, and messages with a score greater or equal 100 with red and yellow. This might be unusual to you if you're used to e.g. slrn's scoring mechanism, but it is more flexible, as it visually marks different scores.

+27. Spam detection
- See _\bM_\be_\bs_\bs_\ba_\bg_\be _\bM_\ba_\bt_\bc_\bh_\bi_\bn_\bg _\bi_\bn _\bH_\bo_\bo_\bk_\bs (section 4.5.1 , page 57) for information on the
- exact format of _\bp_\ba_\bt_\bt_\be_\br_\bn.
+ Usage: spam pattern format Usage: nospam pattern
- Example: fcc-hook [@.]aol\\.com$ +spammers
+ Mutt-ng has generalized support for external spam-scoring filters. By defining your spam patterns with the spam and nospam commands, you can limit, search, and sort your mail based on its spam attributes, as determined by the external filter. You also can display the spam attributes in your index display using the %H selector in the index-format variable. (Tip: try %?H?[%H] ? to display spam tags only when they are defined for a given message.)
- The above will save a copy of all messages going to the aol.com domain to the
- `+spammers' mailbox by default. Also see the _\bf_\bc_\bc_\b-_\bs_\ba_\bv_\be_\b-_\bh_\bo_\bo_\bk (section 3.20 ,
- page 39) command.
+ Your first step is to define your external filter's spam patterns using the spam command. pattern should be a regular expression that matches a header in a mail message. If any message in the mailbox matches this regular expression, it will receive a ``spam tag'' or ``spam attribute'' (unless it also matches a nospam pattern -- see below.) The appearance of this attribute is entirely up to you, and is governed by the format parameter. format can be any static text, but it also can include back-references from the pattern expression. (A regular expression ``back-reference'' refers to a sub-expression contained within parentheses.) %1 is replaced with the first back-reference in the regex, %2 with the second, etc.
- _\b3_\b._\b2_\b0 _\bS_\bp_\be_\bc_\bi_\bf_\by _\bd_\be_\bf_\ba_\bu_\bl_\bt _\bs_\ba_\bv_\be _\bf_\bi_\bl_\be_\bn_\ba_\bm_\be _\ba_\bn_\bd _\bd_\be_\bf_\ba_\bu_\bl_\bt _\bF_\bc_\bc_\b: _\bm_\ba_\bi_\bl_\bb_\bo_\bx _\ba_\bt _\bo_\bn_\bc_\be
+ If you're using multiple spam filters, a message can have more than one spam-related header. You can define spam patterns for each filter you use. If a message matches two or more of these patterns, and the $spam_separator variable is set to a string, then the message's spam tag will consist of all the format strings joined together, with the value of $spam_separator separating them.
- Usage: fcc-save-hook [!]_\bp_\ba_\bt_\bt_\be_\br_\bn _\bm_\ba_\bi_\bl_\bb_\bo_\bx
+ For example, suppose I use DCC, SpamAssassin, and PureMessage. I might define these spam settings:
+spam "X-DCC-.*-Metrics:.*(....)=many" "90+/DCC-%1"
+spam "X-Spam-Status: Yes" "90+/SA"
+spam "X-PerlMX-Spam: .*Probability=([0-9]+)%" "%1/PM"
+set spam_separator=", "
- This command is a shortcut, equivalent to doing both a _\bf_\bc_\bc_\b-_\bh_\bo_\bo_\bk (section
- 3.19 , page 38) and a _\bs_\ba_\bv_\be_\b-_\bh_\bo_\bo_\bk (section 3.18 , page 38) with its arguments.
+ If I then received a message that DCC registered with ``many'' hits under the ``Fuz2'' checksum, and that PureMessage registered with a 97% probability of being spam, that message's spam tag would read 90+/DCC-Fuz2, 97/PM. (The four characters before ``=many'' in a DCC report indicate the checksum used -- in this case, ``Fuz2''.)
- _\b3_\b._\b2_\b1 _\bC_\bh_\ba_\bn_\bg_\be _\bs_\be_\bt_\bt_\bi_\bn_\bg_\bs _\bb_\ba_\bs_\be_\bd _\bu_\bp_\bo_\bn _\bm_\be_\bs_\bs_\ba_\bg_\be _\br_\be_\bc_\bi_\bp_\bi_\be_\bn_\bt_\bs
+ If the $spam_separator variable is unset, then each spam pattern match supersedes the previous one. Instead of getting joined format strings, you'll get only the last one to match.
- Usage: reply-hook [!]_\bp_\ba_\bt_\bt_\be_\br_\bn _\bc_\bo_\bm_\bm_\ba_\bn_\bd
+ The spam tag is what will be displayed in the index when you use %H in the $index_format variable. It's also the string that the ˜H pattern-matching expression matches against for search and limit functions. And it's what sorting by spam attribute will use as a sort key.
- Usage: send-hook [!]_\bp_\ba_\bt_\bt_\be_\br_\bn _\bc_\bo_\bm_\bm_\ba_\bn_\bd
+ That's a pretty complicated example, and most people's actual environments will have only one spam filter. The simpler your configuration, the more effective mutt can be, especially when it comes to sorting.
- Usage: send2-hook [!]_\bp_\ba_\bt_\bt_\be_\br_\bn _\bc_\bo_\bm_\bm_\ba_\bn_\bd
+ Generally, when you sort by spam tag, mutt will sort lexically -- that is, by ordering strings alphnumerically. However, if a spam tag begins with a number, mutt will sort numerically first, and lexically only when two numbers are equal in value. (This is like UNIX's sort -n.) A message with no spam attributes at all -- that is, one that didn't match any of your spam patterns -- is sorted at lowest priority. Numbers are sorted next, beginning with 0 and ranging upward. Finally, non-numeric strings are sorted, with ``a'' taking lower priority than ``z''. Clearly, in general, sorting by spam tags is most effective when you can coerce your filter to give you a raw number. But in case you can't, mutt can still do something useful.
- These commands can be used to execute arbitrary configuration commands based
- upon recipients of the message. _\bp_\ba_\bt_\bt_\be_\br_\bn is a regular expression matching the
- desired address. _\bc_\bo_\bm_\bm_\ba_\bn_\bd is executed when _\br_\be_\bg_\be_\bx_\bp matches recipients of the
- message.
+ The nospam command can be used to write exceptions to spam patterns. If a header pattern matches something in a spam command, but you nonetheless do not want it to receive a spam tag, you can list a more precise pattern under a nospam command.
- reply-hook is matched against the message you are _\br_\be_\bp_\bl_\by_\bi_\bn_\bg t\bto\bo, instead of the
- message you are _\bs_\be_\bn_\bd_\bi_\bn_\bg. send-hook is matched against all messages, both _\bn_\be_\bw
- and _\br_\be_\bp_\bl_\bi_\be_\bs. N\bNo\bot\bte\be:\b: reply-hooks are matched b\bbe\bef\bfo\bor\bre\be the send-hook, r\bre\beg\bga\bar\brd\bdl\ble\bes\bss\bs of
- the order specified in the users's configuration file.
+ If the pattern given to nospam is exactly the same as the pattern on an existing spam list entry, the effect will be to remove the entry from the spam list, instead of adding an exception. Likewise, if the pattern for a spam command matches an entry on the nospam list, that nospam entry will be removed. If the pattern for nospam is ``*'', all entries on both lists will be removed. This might be the default action if you use spam and nospam in conjunction with a folder-hook.
- send2-hook is matched every time a message is changed, either by editing it, or
- by using the compose menu to change its recipients or subject. send2-hook is
- executed after send-hook, and can, e.g., be used to set parameters such as the
- _\b$_\bs_\be_\bn_\bd_\bm_\ba_\bi_\bl (section 7.4.254 , page 150) variable depending on the message's
- sender address.
+ You can have as many spam or nospam commands as you like. You can even do your own primitive spam detection within mutt -- for example, if you consider all mail from MAILER-DAEMON to be spam, you can use a spam command like this:
+spam "^From: .*MAILER-DAEMON" "999"
- For each type of send-hook or reply-hook, when multiple matches occur, commands
- are executed in the order they are specified in the muttrc (for that type of
- hook).
+28. Setting variables
- See _\bM_\be_\bs_\bs_\ba_\bg_\be _\bM_\ba_\bt_\bc_\bh_\bi_\bn_\bg _\bi_\bn _\bH_\bo_\bo_\bk_\bs (section 4.5.1 , page 57) for information on the
- exact format of _\bp_\ba_\bt_\bt_\be_\br_\bn.
+ Usage: set [no|inv]variable[=value] [ variable ... ] Usage: toggle variable [variable ... ] Usage: unset variable [variable ... ] Usage: reset variable [variable ... ]
- Example: send-hook mutt 'set mime_forward signature='''
+ This command is used to set (and unset) variables. There are four basic types of variables: boolean, number, string and quadoption. boolean variables can be set (true) or unset (false). number variables can be assigned a positive integer value.
- Another typical use for this command is to change the values of the
+ string variables consist of any number of printable characters. strings must be enclosed in quotes if they contain spaces or tabs. You may also use the ``C'' escape sequences \n and \t for newline and tab, respectively.
- The Mutt Next Generation E-Mail Client 40
+ quadoption variables are used to control whether or not to be prompted for certain actions, or to specify a default action. A value of yes will cause the action to be carried out automatically as if you had answered yes to the question. Similarly, a value of no will cause the the action to be carried out as if you had answered ``no.'' A value of ask-yes will cause a prompt with a default answer of ``yes'' and ask-no will provide a default answer of ``no.''
- _\b$_\ba_\bt_\bt_\br_\bi_\bb_\bu_\bt_\bi_\bo_\bn (section 7.4.18 , page 93), _\b$_\bs_\bi_\bg_\bn_\ba_\bt_\bu_\br_\be (section 7.4.266 , page
- 153) and _\b$_\bl_\bo_\bc_\ba_\bl_\be (section 7.4.120 , page 119) variables in order to change the
- language of the attributions and signatures based upon the recipients.
+ Prefixing a variable with ``no'' will unset it. Example: set noaskbcc.
- N\bNo\bot\bte\be:\b: the send-hook's are only executed ONCE after getting the initial list of
- recipients. Adding a recipient after replying or editing the message will NOT
- cause any send-hook to be executed. Also note that my_hdr commands which mod-
- ify recipient headers, or the message's subject, don't have any effect on the
- current message when executed from a send-hook.
+ For boolean variables, you may optionally prefix the variable name with inv to toggle the value (on or off). This is useful when writing macros. Example: set invsmart_wrap.
- _\b3_\b._\b2_\b2 _\bC_\bh_\ba_\bn_\bg_\be _\bs_\be_\bt_\bt_\bi_\bn_\bg_\bs _\bb_\be_\bf_\bo_\br_\be _\bf_\bo_\br_\bm_\ba_\bt_\bt_\bi_\bn_\bg _\ba _\bm_\be_\bs_\bs_\ba_\bg_\be
+ The toggle command automatically prepends the inv prefix to all specified variables.
- Usage: message-hook [!]_\bp_\ba_\bt_\bt_\be_\br_\bn _\bc_\bo_\bm_\bm_\ba_\bn_\bd
+ The unset command automatically prepends the no prefix to all specified variables.
- This command can be used to execute arbitrary configuration commands before
- viewing or formatting a message based upon information about the message. _\bc_\bo_\bm_\b-
- _\bm_\ba_\bn_\bd is executed if the _\bp_\ba_\bt_\bt_\be_\br_\bn matches the message to be displayed. When mul-
- tiple matches occur, commands are executed in the order they are specified in
- the muttrc.
+ Using the enter-command function in the index menu, you can query the value of a variable by prefixing the name of the variable with a question mark:
+set ?allow_8bit
- See _\bM_\be_\bs_\bs_\ba_\bg_\be _\bM_\ba_\bt_\bc_\bh_\bi_\bn_\bg _\bi_\bn _\bH_\bo_\bo_\bk_\bs (section 4.5.1 , page 57) for information on the
- exact format of _\bp_\ba_\bt_\bt_\be_\br_\bn.
+ The question mark is actually only required for boolean and quadoption variables.
- Example:
+ The reset command resets all given variables to the compile time defaults (hopefully mentioned in this manual). If you use the command set and prefix the variable with ``&'' this has the same behavior as the reset command.
- message-hook ~A 'set pager=builtin'
- message-hook '~f freshmeat-news' 'set pager="less \"+/^ subject: .*\""'
+ With the reset command there exists the special variable ``all'', which allows you to reset all variables to their system defaults.

+29. Reading initialization commands from another file
- Usage: crypt-hook _\bp_\ba_\bt_\bt_\be_\br_\bn _\bk_\be_\by_\bi_\bd
+ Usage: source filename [ filename ... ]
- When encrypting messages with PGP or OpenSSL, you may want to associate a cer-
- tain key with a given e-mail address automatically, either because the recipi-
- ent's public key can't be deduced from the destination address, or because, for
- some reasons, you need to override the key Mutt-ng would normally use. The
- crypt-hook command provides a method by which you can specify the ID of the
- public key to be used when encrypting messages to a certain recipient.
+ This command allows the inclusion of initialization commands from other files. For example, I place all of my aliases in ˜/.mail_aliases so that I can make my ˜/.muttrc readable and keep my aliases private.
- The meaning of "key id" is to be taken broadly in this context: You can either
- put a numerical key ID here, an e-mail address, or even just a real name.
+ If the filename begins with a tilde (``˜''), it will be expanded to the path of your home directory.
- _\b3_\b._\b2_\b4 _\bA_\bd_\bd_\bi_\bn_\bg _\bk_\be_\by _\bs_\be_\bq_\bu_\be_\bn_\bc_\be_\bs _\bt_\bo _\bt_\bh_\be _\bk_\be_\by_\bb_\bo_\ba_\br_\bd _\bb_\bu_\bf_\bf_\be_\br
+ If the filename ends with a vertical bar (|), then filename is considered to be an executable program from which to read input (eg. source ˜/bin/myscript|).
- Usage: push _\bs_\bt_\br_\bi_\bn_\bg
+30. Removing hooks
- This command adds the named string to the keyboard buffer. The string may
+ Usage: unhook [ * | hook-type ]
- The Mutt Next Generation E-Mail Client 41
+ This command permits you to flush hooks you have previously defined. You can either remove all hooks by giving the ``*'' character as an argument, or you can remove all hooks of a specific type by saying something like unhook send-hook.
- contain control characters, key names and function names like the sequence
- string in the _\bm_\ba_\bc_\br_\bo (section 3.8 , page 29) command. You may use it to auto-
- matically run a sequence of commands at startup, or when entering certain fold-
- ers.
+31. Sharing Setups
- _\b3_\b._\b2_\b5 _\bE_\bx_\be_\bc_\bu_\bt_\bi_\bn_\bg _\bf_\bu_\bn_\bc_\bt_\bi_\bo_\bn_\bs
+31.1. Character Sets
- Usage: exec _\bf_\bu_\bn_\bc_\bt_\bi_\bo_\bn [ _\bf_\bu_\bn_\bc_\bt_\bi_\bo_\bn ... ]
+ As users may run mutt-ng on different systems, the configuration must be maintained because it's likely that people want to use the setup everywhere they use mutt-ng. And mutt-ng tries to help where it can.
- This command can be used to execute any function. Functions are listed in the
- _\bf_\bu_\bn_\bc_\bt_\bi_\bo_\bn _\br_\be_\bf_\be_\br_\be_\bn_\bc_\be (section 7.5 , page 174). ``exec function'' is equivalent
- to ``push <function>''.
+ To not produce conflicts with different character sets, mutt-ng allows users to specify in which character set their configuration files are encoded. Please note that while reading the configuration files, this is only respected after the corresponding declaration appears. It's advised to put the following at the very beginning of a users muttngrc:
+set config_charset = "..."
- _\b3_\b._\b2_\b6 _\bM_\be_\bs_\bs_\ba_\bg_\be _\bS_\bc_\bo_\br_\bi_\bn_\bg
+ and replacing the dots with the actual character set. To avoid problems while maintaining the setup, vim user's may want to use modelines as show in:
+# vim:fileencoding=...:
- Usage: score _\bp_\ba_\bt_\bt_\be_\br_\bn _\bv_\ba_\bl_\bu_\be
+ while, again, replacing the dots with the appropriate name. This tells vim as which character set to read and save the file.
- Usage: unscore _\bp_\ba_\bt_\bt_\be_\br_\bn [ _\bp_\ba_\bt_\bt_\be_\br_\bn ... ]
+31.2. Modularization
- In situations where you have to cope with a lot of emails, e.g. when you read
- many different mailing lists, and take part in discussions, it is always useful
- to have the important messages marked and the annoying messages or the ones
- that you aren't interested in deleted. For this purpose, mutt-ng features a
- mechanism called ``scoring''.
+ ``Modularization'' means to divide the setup into several files while sorting the options or commands by topic. Especially for longer setups (e.g. with many hooks), this helps maintaining it and solving trouble.
- When you use scoring, every message has a base score of 0. You can then use the
- score command to define patterns and a positive or negative value associated
- with it. When a pattern matches a message, the message's score will be raised
- or lowered by the amount of the value associated with the pattern.
+ When using separation, setups may be, as a whole or in fractions, shared over different systems.
- score "~f nion@muttng\.org" 50
- score "~f @sco\.com" -100
+31.3. Conditional parts
- If the pattern matches, it is also possible to set the score value of the cur-
- rent message to a certain value and then stop evaluation:
+ When using a configuration on different systems, the user may not always have influence on how mutt-ng is installed and which features it includes.
- score "~f santaclaus@northpole\.int" =666
+ To solve this, mutt-ng contain a feature based on the ``ifdef'' patch written for mutt. Its basic syntax is:
+ifdef <item> <command>
+ifndef <item> <command>
- What is important to note is that negative score values will be rounded up to
- 0.
+ ...whereby <item> can be one of:
+ * a function name
+ * a variable name
+ * a menu name
+ * a feature name
- To make scoring actually useful, the score must be applied in some way. That's
- what the _\bs_\bc_\bo_\br_\be _\bt_\bh_\br_\be_\bs_\bh_\bo_\bl_\bd_\bs are for. Currently, there are three score thresholds:
+ All available functions, variables and menus are documented elsewhere in this manual but ``features'' is specific to these two commands. To test for one, prefix one of the following keywords with feature_:
+ncurses, slang, iconv, idn, dotlock, standalone, pop, nntp, imap, ssl,
+gnutls, sasl, sasl2, libesmtp, compressed, color, classic_pgp,
+classic_smime, gpgme, header_cache
- +\bo flag threshold: when a message has a score value equal or higher than the
- flag threshold, it will be flagged.
+ As an example, one can use the following in ˜/.muttngrc:
+ifdef feature_imap 'source ~/.mutt-ng/setup-imap'
+ifdef feature_pop 'source ~/.mutt-ng/setup-pop'
+ifdef feature_nntp 'source ~/.mutt-ng/setup-nntp'
- The Mutt Next Generation E-Mail Client 42
+ ...to only source ˜/.mutt-ng/setup-imap if IMAP support is built in, only source ˜/.mutt-ng/setup-pop if POP support is built in and only source ˜/.mutt-ng/setup-nntp if NNTP support is built in.
- +\bo read threshold: when a message has a score value equal or lower than the
- read threshold, it will be marked as read.
+ An example for testing for variable names can be used if users use different revisions of mutt-ng whereby the older one may not have a certain variable. To test for the availability of imap-mail-check, use:
+ifdef imap_mail_check 'set imap_mail_check = 300'
- +\bo delete threshold: when a message has a score value equal or lower than the
- delete threshold, it will be marked as deleted.
+ Provided for completeness is the test for menu names. To set pager-index-lines only if the pager menu is available, use:
+ifdef pager 'set pager_index_lines = 10'
- These three thresholds can be set via the variables _\b$_\bs_\bc_\bo_\br_\be_\b__\bt_\bh_\br_\be_\bs_\bh_\bo_\bl_\bd_\b__\bf_\bl_\ba_\bg (sec-
- tion 7.4.251 , page 149), _\b$_\bs_\bc_\bo_\br_\be_\b__\bt_\bh_\br_\be_\bs_\bh_\bo_\bl_\bd_\b__\br_\be_\ba_\bd (section 7.4.252 , page 150),
- _\b$_\bs_\bc_\bo_\br_\be_\b__\bt_\bh_\br_\be_\bs_\bh_\bo_\bl_\bd_\b__\bd_\be_\bl_\be_\bt_\be (section 7.4.250 , page 149) and. By default,
- _\b$_\bs_\bc_\bo_\br_\be_\b__\bt_\bh_\br_\be_\bs_\bh_\bo_\bl_\bd_\b__\br_\be_\ba_\bd (section 7.4.252 , page 150) and _\b$_\bs_\bc_\bo_\br_\be_\b__\bt_\bh_\br_\be_\bs_\bh_\bo_\bl_\bd_\b__\bd_\be_\bl_\be_\bt_\be
- (section 7.4.250 , page 149) are set to -1, which means that in the default
- threshold configuration no message will ever get marked as read or deleted.
+ For completeness, too, the opposite of ifdef is provided: ifndef which only executes the command if the test fails. For example, the following two examples are equivalent:
+ifdef feature_ncurses 'source ~/.mutt-ng/setup-ncurses'
+ifndef feature_ncurses 'source ~/.mutt-ng/setup-slang'
- Scoring gets especially interesting when combined with the color command and
- the ~n pattern:
+ ...and...
+ifdef feature_slang 'source ~/.mutt-ng/setup-slang'
+ifndef feature_slang 'source ~/.mutt-ng/setup-ncurses'
- color index black yellow "~n 10-"
- color index red yellow "~n 100-"
+32. Obsolete Variables
- The rules above mark all messages with a score between 10 and 99 with black and
- yellow, and messages with a score greater or equal 100 with red and yellow.
- This might be unusual to you if you're used to e.g. slrn's scoring mechanism,
- but it is more flexible, as it visually marks different scores.
+ In the process of ensuring and creating more consistency, many variables have been renamed and some of the old names were already removed. Please see sect-obsolete for a complete list.

+ Table of Contents
- Usage: nospam _\bp_\ba_\bt_\bt_\be_\br_\bn
+ 1. Regular Expressions
+ 2. Patterns
- Mutt-ng has generalized support for external spam-scoring filters. By defining
- your spam patterns with the spam and nospam commands, you can _\bl_\bi_\bm_\bi_\bt, _\bs_\be_\ba_\br_\bc_\bh,
- and _\bs_\bo_\br_\bt your mail based on its spam attributes, as determined by the external
- filter. You also can display the spam attributes in your index display using
- the %H selector in the _\b$_\bi_\bn_\bd_\be_\bx_\b__\bf_\bo_\br_\bm_\ba_\bt (section 7.4.116 , page 115) variable.
- (Tip: try %?H?[%H] ? to display spam tags only when they are defined for a
- given message.)
+ 2.1. Complex Patterns
+ 2.2. Patterns and Dates
- Your first step is to define your external filter's spam patterns using the
- spam command. _\bp_\ba_\bt_\bt_\be_\br_\bn should be a regular expression that matches a header in a
- mail message. If any message in the mailbox matches this regular expression, it
- will receive a ``spam tag'' or ``spam attribute'' (unless it also matches a
- nospam pattern -- see below.) The appearance of this attribute is entirely up
- to you, and is governed by the _\bf_\bo_\br_\bm_\ba_\bt parameter. _\bf_\bo_\br_\bm_\ba_\bt can be any static text,
- but it also can include back-references from the _\bp_\ba_\bt_\bt_\be_\br_\bn expression. (A regular
- expression ``back-reference'' refers to a sub-expression contained within
- parentheses.) %1 is replaced with the first back-reference in the regex, %2
- with the second, etc.
+ 3. Format Strings
- If you're using multiple spam filters, a message can have more than one spam-

+ 3.2. Conditional Expansion
+ 3.3. Modifications and Padding
- The Mutt Next Generation E-Mail Client 43
+ 4. Using Tags
+ 5. Using Hooks
- related header. You can define spam patterns for each filter you use. If a mes-
- sage matches two or more of these patterns, and the $spam_separator variable is
- set to a string, then the message's spam tag will consist of all the _\bf_\bo_\br_\bm_\ba_\bt
- strings joined together, with the value of $spam_separator separating them.
+ 5.1. Message Matching in Hooks
- For example, suppose I use DCC, SpamAssassin, and PureMessage. I might define
- these spam settings:
+ 6. Using the sidebar
+ 7. External Address Queries
+ 8. Mailbox Formats
+ 9. Mailbox Shortcuts
+ 10. Handling Mailing Lists
+ 11. Editing threads
- spam "X-DCC-.*-Metrics:.*(....)=many" "90+/DCC-%1"
- spam "X-Spam-Status: Yes" "90+/SA"
- spam "X-PerlMX-Spam: .*Probability=([0-9]+)%" "%1/PM"
- set spam_separator=", "
+ 11.1. Linking threads
+ 11.2. Breaking threads
- If I then received a message that DCC registered with ``many'' hits under the
- ``Fuz2'' checksum, and that PureMessage registered with a 97% probability of
- being spam, that message's spam tag would read 90+/DCC-Fuz2, 97/PM. (The four
- characters before ``=many'' in a DCC report indicate the checksum used -- in
- this case, ``Fuz2''.)
+ 12. Delivery Status Notification (DSN) Support
+ 13. POP3 Support (OPTIONAL)
+ 14. IMAP Support (OPTIONAL)
- If the $spam_separator variable is unset, then each spam pattern match super-
- sedes the previous one. Instead of getting joined _\bf_\bo_\br_\bm_\ba_\bt strings, you'll get
- only the last one to match.
+ 14.1. The Folder Browser
+ 14.2. Authentication
- The spam tag is what will be displayed in the index when you use %H in the
- $index_format variable. It's also the string that the ~H pattern-matching
- expression matches against for _\bs_\be_\ba_\br_\bc_\bh and _\bl_\bi_\bm_\bi_\bt functions. And it's what sort-
- ing by spam attribute will use as a sort key.
+ 15. NNTP Support (OPTIONAL)
- That's a pretty complicated example, and most people's actual environments will
- have only one spam filter. The simpler your configuration, the more effective
- mutt can be, especially when it comes to sorting.
+ 15.1. Again: Scoring
- Generally, when you sort by spam tag, mutt will sort _\bl_\be_\bx_\bi_\bc_\ba_\bl_\bl_\by -- that is, by
- ordering strings alphnumerically. However, if a spam tag begins with a number,
- mutt will sort numerically first, and lexically only when two numbers are equal
- in value. (This is like UNIX's sort -n.) A message with no spam attributes at
- all -- that is, one that didn't match _\ba_\bn_\by of your spam patterns -- is sorted at
- lowest priority. Numbers are sorted next, beginning with 0 and ranging upward.
- Finally, non-numeric strings are sorted, with ``a'' taking lower priority than
- ``z''. Clearly, in general, sorting by spam tags is most effective when you can
- coerce your filter to give you a raw number. But in case you can't, mutt can
- still do something useful.
+ 16. SMTP Support (OPTIONAL)
+ 17. Managing multiple IMAP/POP/NNTP accounts (OPTIONAL)
+ 18. Start a WWW Browser on URLs (EXTERNAL)
+ 19. Compressed folders Support (OPTIONAL)
- The nospam command can be used to write exceptions to spam patterns. If a
- header pattern matches something in a spam command, but you nonetheless do not
- want it to receive a spam tag, you can list a more precise pattern under a
- nospam command.
+ 19.1. Open a compressed mailbox for reading
+ 19.2. Write a compressed mailbox
+ 19.3. Append a message to a compressed mailbox
+ 19.4. Encrypted folders
- If the _\bp_\ba_\bt_\bt_\be_\br_\bn given to nospam is exactly the same as the _\bp_\ba_\bt_\bt_\be_\br_\bn on an exist-
- ing spam list entry, the effect will be to remove the entry from the spam list,
- instead of adding an exception. Likewise, if the _\bp_\ba_\bt_\bt_\be_\br_\bn for a spam command
- matches an entry on the nospam list, that nospam entry will be removed. If the
- _\bp_\ba_\bt_\bt_\be_\br_\bn for nospam is ``*'', _\ba_\bl_\bl _\be_\bn_\bt_\br_\bi_\be_\bs _\bo_\bn _\bb_\bo_\bt_\bh _\bl_\bi_\bs_\bt_\bs will be removed. This
+1. Regular Expressions
- The Mutt Next Generation E-Mail Client 44
+ All string patterns in Mutt-ng including those in more complex patterns must be specified using regular expressions (regexp) in the ``POSIX extended'' syntax (which is more or less the syntax used by egrep and GNU awk). For your convenience, we have included below a brief description of this syntax.
- might be the default action if you use spam and nospam in conjunction with a
- folder-hook.
+ The search is case sensitive if the pattern contains at least one upper case letter, and case insensitive otherwise. Note that ``\'' must be quoted if used for a regular expression in an initialization command: ``\\''.
- You can have as many spam or nospam commands as you like. You can even do your
- own primitive spam detection within mutt -- for example, if you consider all
- mail from MAILER-DAEMON to be spam, you can use a spam command like this:
+ A regular expression is a pattern that describes a set of strings. Regular expressions are constructed analogously to arithmetic expressions, by using various operators to combine smaller expressions.
- spam "^From: .*MAILER-DAEMON" "999"
+ Note that the regular expression can be enclosed/delimited by either " or ' which is useful if the regular expression includes a white-space character. See muttrc-syntax for more information on " and ' delimiter processing. To match a literal " or ' you must preface it with \ (backslash).
- _\b3_\b._\b2_\b8 _\bS_\be_\bt_\bt_\bi_\bn_\bg _\bv_\ba_\br_\bi_\ba_\bb_\bl_\be_\bs
+ The fundamental building blocks are the regular expressions that match a single character. Most characters, including all letters and digits, are regular expressions that match themselves. Any metacharacter with special meaning may be quoted by preceding it with a backslash.
- Usage: set [no|inv]_\bv_\ba_\br_\bi_\ba_\bb_\bl_\be[=_\bv_\ba_\bl_\bu_\be] [ _\bv_\ba_\br_\bi_\ba_\bb_\bl_\be ... ]
+ The period ``.'' matches any single character. The caret ``^'' and the dollar sign ``$'' are metacharacters that respectively match the empty string at the beginning and end of a line.
- Usage: toggle _\bv_\ba_\br_\bi_\ba_\bb_\bl_\be [_\bv_\ba_\br_\bi_\ba_\bb_\bl_\be ... ]
+ A list of characters enclosed by ``['' and ``]'' matches any single character in that list; if the first character of the list is a caret ``^'' then it matches any character not in the list. For example, the regular expression [0123456789] matches any single digit. A range of ASCII characters may be specified by giving the first and last characters, separated by a hyphen ``-''. Most metacharacters lose their special meaning inside lists. To include a literal ``]'' place it first in the list. Similarly, to include a literal ``^'' place it anywhere but first. Finally, to include a literal hyphen ``-'' place it last.
- Usage: unset _\bv_\ba_\br_\bi_\ba_\bb_\bl_\be [_\bv_\ba_\br_\bi_\ba_\bb_\bl_\be ... ]
+ Certain named classes of characters are predefined. Character classes consist of ``[:'', a keyword denoting the class, and ``:]''. The following classes are defined by the POSIX standard:
- Usage: reset _\bv_\ba_\br_\bi_\ba_\bb_\bl_\be [_\bv_\ba_\br_\bi_\ba_\bb_\bl_\be ... ]
+ [:alnum:]
+ Alphanumeric characters.
- This command is used to set (and unset) _\bc_\bo_\bn_\bf_\bi_\bg_\bu_\br_\ba_\bt_\bi_\bo_\bn _\bv_\ba_\br_\bi_\ba_\bb_\bl_\be_\bs (section 7.4 ,
- page 87). There are four basic types of variables: boolean, number, string and
- quadoption. _\bb_\bo_\bo_\bl_\be_\ba_\bn variables can be _\bs_\be_\bt (true) or _\bu_\bn_\bs_\be_\bt (false). _\bn_\bu_\bm_\bb_\be_\br
- variables can be assigned a positive integer value.
+ [:alpha:]
+ Alphabetic characters.
- _\bs_\bt_\br_\bi_\bn_\bg variables consist of any number of printable characters. _\bs_\bt_\br_\bi_\bn_\bg_\bs must
- be enclosed in quotes if they contain spaces or tabs. You may also use the
- ``C'' escape sequences \\b\n\bn and \\b\t\bt for newline and tab, respectively.
+ [:blank:]
+ Space or tab characters.
- _\bq_\bu_\ba_\bd_\bo_\bp_\bt_\bi_\bo_\bn variables are used to control whether or not to be prompted for cer-
- tain actions, or to specify a default action. A value of _\by_\be_\bs will cause the
- action to be carried out automatically as if you had answered yes to the ques-
- tion. Similarly, a value of _\bn_\bo will cause the the action to be carried out as
- if you had answered ``no.'' A value of _\ba_\bs_\bk_\b-_\by_\be_\bs will cause a prompt with a
- default answer of ``yes'' and _\ba_\bs_\bk_\b-_\bn_\bo will provide a default answer of ``no.''
+ [:cntrl:]
+ Control characters.
- Prefixing a variable with ``no'' will unset it. Example: set noaskbcc.
+ [:digit:]
+ Numeric characters.
- For _\bb_\bo_\bo_\bl_\be_\ba_\bn variables, you may optionally prefix the variable name with inv to
- toggle the value (on or off). This is useful when writing macros. Example:
- set invsmart_wrap.
+ [:graph:]
+ Characters that are both printable and visible. (A space is printable, but not visible, while an ``a'' is both.)
- The toggle command automatically prepends the inv prefix to all specified vari-
- ables.
+ [:lower:]
+ Lower-case alphabetic characters.
- The unset command automatically prepends the no prefix to all specified vari-
- ables.
+ [:print:]
+ Printable characters (characters that are not control characters.)
- Using the enter-command function in the _\bi_\bn_\bd_\be_\bx menu, you can query the value of
- a variable by prefixing the name of the variable with a question mark:
+ [:punct:]
+ Punctuation characters (characters that are not letter, digits, control characters, or space characters).
- The Mutt Next Generation E-Mail Client 45
+ [:space:]
+ Space characters (such as space, tab and formfeed, to name a few).
- set ?allow_8bit
+ [:upper:]
+ Upper-case alphabetic characters.
- The question mark is actually only required for boolean and quadoption vari-
- ables.
+ [:xdigit:]
+ Characters that are hexadecimal digits.
- The reset command resets all given variables to the compile time defaults
- (hopefully mentioned in this manual). If you use the command set and prefix the
- variable with ``&'' this has the same behavior as the reset command.
+ A character class is only valid in a regular expression inside the brackets of a character list. Note that the brackets in these class names are part of the symbolic names, and must be included in addition to the brackets delimiting the bracket list. For example, [[:digit:]] is equivalent to [0-9].
- With the reset command there exists the special variable ``all'', which allows
- you to reset all variables to their system defaults.
+ Two additional special sequences can appear in character lists. These apply to non-ASCII character sets, which can have single symbols (called collating elements) that are represented with more than one character, as well as several characters that are equivalent for collating or sorting purposes:
- _\b3_\b._\b2_\b9 _\bR_\be_\ba_\bd_\bi_\bn_\bg _\bi_\bn_\bi_\bt_\bi_\ba_\bl_\bi_\bz_\ba_\bt_\bi_\bo_\bn _\bc_\bo_\bm_\bm_\ba_\bn_\bd_\bs _\bf_\br_\bo_\bm _\ba_\bn_\bo_\bt_\bh_\be_\br _\bf_\bi_\bl_\be
+ Collating Symbols
+ A collating symbol is a multi-character collating element enclosed in ``[.'' and ``.]''. For example, if ``ch'' is a collating element, then [[.ch.]] is a regexp that matches this collating element, while [ch] is a regexp that matches either ``c'' or ``h''.
- Usage: source _\bf_\bi_\bl_\be_\bn_\ba_\bm_\be [ _\bf_\bi_\bl_\be_\bn_\ba_\bm_\be ... ]
+ Equivalence Classes
+ An equivalence class is a locale-specific name for a list of characters that are equivalent. The name is enclosed in ``[='' and ``=]''. For example, the name ``e'' might be used to represent all of ``è'' ``é'' and ``e''. In this case, [[=e=]] is a regexp that matches any of ``è'', ``é'' and ``e''.
- This command allows the inclusion of initialization commands from other files.
- For example, I place all of my aliases in ~/.mail_aliases so that I can make my
- ~/.muttrc readable and keep my aliases private.
+ A regular expression matching a single character may be followed by one of several repetition operators:
- If the filename begins with a tilde (``~''), it will be expanded to the path of
- your home directory.
+ ?
+ The preceding item is optional and matched at most once.
- If the filename ends with a vertical bar (|), then _\bf_\bi_\bl_\be_\bn_\ba_\bm_\be is considered to be
- an executable program from which to read input (eg. source ~/bin/myscript|).
+ *
+ The preceding item will be matched zero or more times.
- _\b3_\b._\b3_\b0 _\bR_\be_\bm_\bo_\bv_\bi_\bn_\bg _\bh_\bo_\bo_\bk_\bs
+ +
+ The preceding item will be matched one or more times.
- Usage: unhook [ * | _\bh_\bo_\bo_\bk_\b-_\bt_\by_\bp_\be ]
+ {n}
+ The preceding item is matched exactly n times.
- This command permits you to flush hooks you have previously defined. You can
- either remove all hooks by giving the ``*'' character as an argument, or you
- can remove all hooks of a specific type by saying something like unhook send-
- hook.
+ {n,}
+ The preceding item is matched n or more times.
- _\b3_\b._\b3_\b1 _\bS_\bh_\ba_\br_\bi_\bn_\bg _\bS_\be_\bt_\bu_\bp_\bs
+ {,m}
+ The preceding item is matched at most m times.
- _\b3_\b._\b3_\b1_\b._\b1 _\bC_\bh_\ba_\br_\ba_\bc_\bt_\be_\br _\bS_\be_\bt_\bs
+ {n,m}
+ The preceding item is matched at least n times, but no more than m times.
- As users may run mutt-ng on different systems, the configuration must be main-
- tained because it's likely that people want to use the setup everywhere they
- use mutt-ng. And mutt-ng tries to help where it can.
+ Two regular expressions may be concatenated; the resulting regular expression matches any string formed by concatenating two substrings that respectively match the concatenated subexpressions.
- To not produce conflicts with different character sets, mutt-ng allows users to
- specify in which character set their configuration files are encoded. Please
- note that while reading the configuration files, this is only respected after
- the corresponding declaration appears. It's advised to put the following at the

+ Note: If you compile Mutt-ng with the GNU rx package, the following operators may also be used in regular expressions:
- set config_charset = "..."
+ \\y
+ Matches the empty string at either the beginning or the end of a word.
- and replacing the dots with the actual character set. To avoid problems while
- maintaining the setup, vim user's may want to use modelines as show in:
+ \\B
+ Matches the empty string within a word.
- # vim:fileencoding=...:

+ Matches the empty string at the beginning of a word.
- while, again, replacing the dots with the appropriate name. This tells vim as

+ Matches the empty string at the end of a word.
- _\b3_\b._\b3_\b1_\b._\b2 _\bM_\bo_\bd_\bu_\bl_\ba_\br_\bi_\bz_\ba_\bt_\bi_\bo_\bn
+ \\w
+ Matches any word-constituent character (letter, digit, or underscore).
- ``Modularization'' means to divide the setup into several files while sorting
- the options or commands by topic. Especially for longer setups (e.g. with many

+ \\W
+ Matches any character that is not word-constituent.
- When using separation, setups may be, as a whole or in fractions, shared over

- _\b3_\b._\b3_\b1_\b._\b3 _\bC_\bo_\bn_\bd_\bi_\bt_\bi_\bo_\bn_\ba_\bl _\bp_\ba_\br_\bt_\bs
+ \\'
+ Matches the empty string at the end of a buffer.
- When using a configuration on different systems, the user may not always have
- influence on how mutt-ng is installed and which features it includes.
+ Please note however that these operators are not defined by POSIX, so they may or may not be available in stock libraries on various systems.
- To solve this, mutt-ng contain a feature based on the ``ifdef'' patch written
- for mutt. Its basic syntax is:
+2. Patterns
- ifdef <item> <command>
- ifndef <item> <command>
+ Mutt-ng's pattern language provides a simple yet effective way to set up rules to match messages, e.g. for operations like tagging and scoring. A pattern consists of one or more sub-pattern, which can be logically grouped, ORed, and negated. For a complete listing of these patterns, please refer to table patterns in the Reference chapter.
- ...whereby <item> can be one of:
+ It must be noted that in this table, EXPR, USER, ID and SUBJECT are regular expressions. For ranges, the forms <[MAX], >>[MIN], [MIN]- and -[MAX] are also possible.
- +\bo a function name
+2.1. Complex Patterns
- +\bo a variable name
+ It is possible to combine several sub-patterns to a more complex pattern. The most simple possibility is to logically AND several patterns by stringing them together:
+~s 'SPAM' ~U
- +\bo a menu name
+ The pattern above matches all messages that contain ``SPAM'' in the subject and are unread.
- +\bo a feature name
+ To logical OR patterns, simply use the | operator. This one especially useful when using local groups:
+~f ("nion@muttng\.org"|"ak@muttng\.org"|"pdmef@muttng\.org")
+(~b mutt-ng|~s Mutt-ng)
+!~x '@synflood\.at'
- All available functions, variables and menus are documented elsewhere in this
- manual but ``features'' is specific to these two commands. To test for one,
+ The first pattern matches all messages that were sent by one of the mutt-ng maintainers, while the seconds pattern matches all messages that contain ``mutt-ng'' in the message body or ``Mutt-ng'' in the subject. The third pattern matches all messages that do not contain ``@synflood\.at'' in the References: header, i.e. messages that are not an (indirect) reply to one of my messages. A pattern can be logicall negated using the ! operator.

+2.2. Patterns and Dates
- prefix one of the following keywords with feature_:
+ When using dates in patterns, the dates must be specified in a special format, i.e. DD/MM/YYYY. If you don't specify month or year, they default to the current month or year. When using date ranges, and you specify only the minimum or the maximum, the specified date will be excluded, e.g. 01/06/2005- matches against all messages after Juni 1st, 2005.
- ncurses, slang, iconv, idn, dotlock, standalone, pop, nntp, imap, ssl,
- gnutls, sasl, sasl2, libesmtp, compressed, color, classic_pgp,
- classic_smime, gpgme, header_cache
+ It is also possible to use so-called ``error margins'' when specifying date ranges. You simply specify a date, and then the error margin. This margin needs to contain the information whether it goes ``forth'' or ``back'' in time, by using + and -. Then follows a number and a unit, i.e. y for years, m for months, w for weeks and d for days. If you use the special * sign, it means that the error margin goes to both ``directions'' in time.
+~d 01/01/2005+1y
+~d 18/10/2004-2w
+~d 28/12/2004*1d
- As an example, one can use the following in ~/.muttngrc:
+ The first pattern matches all dates between January 1st, 2005 and January 1st 2006. The second pattern matches all dates between October 18th, 2004 and October 4th 2004 (2 weeks before 18/10/2004), while the third pattern matches all dates 1 day around December 28th, 2004 (i.e. Dec 27th, 28th and 29th).
- ifdef feature_imap 'source ~/.mutt-ng/setup-imap'
- ifdef feature_pop 'source ~/.mutt-ng/setup-pop'
- ifdef feature_nntp 'source ~/.mutt-ng/setup-nntp'
+ Relative dates are also very important, as they make it possible to specify date ranges between a fixed number of units and the current date. How this works can be seen in the following example:
+~d >2w # messages older than two weeks
+~d <3d # messages newer than 3 days
+~d =1m # messages that are exactly one month old
- ...to only source ~/.mutt-ng/setup-imap if IMAP support is built in, only
- source ~/.mutt-ng/setup-pop if POP support is built in and only source ~/.mutt-
- ng/setup-nntp if NNTP support is built in.
+3. Format Strings
- An example for testing for variable names can be used if users use different
- revisions of mutt-ng whereby the older one may not have a certain variable. To
- test for the availability of _\b$_\bi_\bm_\ba_\bp_\b__\bm_\ba_\bi_\bl_\b__\bc_\bh_\be_\bc_\bk (section 7.4.105 , page 113),
- use:
+3.1. Introduction
- ifdef imap_mail_check 'set imap_mail_check = 300'
+ The so called Format Strings offer great flexibility when configuring mutt-ng. In short, they describe what items to print out how in menus and status messages.
- Provided for completeness is the test for menu names. To set _\b$_\bp_\ba_\bg_\be_\br_\b__\bi_\bn_\bd_\be_\bx_\b__\bl_\bi_\bn_\be_\bs
- (section 7.4.176 , page 132) only if the pager menu is available, use:
+ Basically, they work as this: for different menus and bars, there's a variable specifying the layout. For every item available, there is a so called expando.
- ifdef pager 'set pager_index_lines = 10'
+ For example, when running mutt-ng on different machines or different versions for testing purposes, it may be interesting to have the following information always printed on screen when one is in the index:
+ * the current hostname
+ * the current mutt-ng version number
- For completeness, too, the opposite of ifdef is provided: ifndef which only
- executes the command if the test fails. For example, the following two examples
- are equivalent:
+ The setting for the status bar of the index is controlled via the status-format variable. For the hostname and version string, there's an expando for $status_format: %h expands to the hostname and %v to the version string. When just configuring:
+set status_format = "%v on %h: ..."
- ifdef feature_ncurses 'source ~/.mutt-ng/setup-ncurses'
- ifndef feature_ncurses 'source ~/.mutt-ng/setup-slang'
+ mutt-ng will replace the sequence %v with the version string and %h with the host's name. When you are, for example, running mutt-ng version 1.5.9i on host mailhost, you'll see the following when you're in the index:
+Mutt-ng 1.5.9i on mailhost: ...
- ...and...
+ In the index, there're more useful information one could want to see:
+ * which mailbox is open
+ * how man new, flagged or postponed messages
+ * ...
- ifdef feature_slang 'source ~/.mutt-ng/setup-slang'
- ifndef feature_slang 'source ~/.mutt-ng/setup-ncurses'
+ To include the mailbox' name is as easy as:
+set status_format = "%v on %h: %B: ...
- The Mutt Next Generation E-Mail Client 48
+ When the currently opened mailbox is Inbox, this will be expanded to:
+Mutt-ng 1.5.9i on mailhost: Inbox: ...
- _\b3_\b._\b3_\b2 _\bO_\bb_\bs_\bo_\bl_\be_\bt_\be _\bV_\ba_\br_\bi_\ba_\bb_\bl_\be_\bs
+ For the number of certain types of messages, one more feature of the format strings is extremely useful. If there aren't messages of a certain type, it may not be desired to print just that there aren't any but instead only print something if there are any.
- In the process of ensuring and creating more consistency, many variables have
- been renamed and some of the old names were already removed. Please see _\bO_\bb_\bs_\bo_\b-
- _\bl_\be_\bt_\be _\bV_\ba_\br_\bi_\ba_\bb_\bl_\be_\bs (section 7.4 , page 87) for a complete list.
+3.2. Conditional Expansion
- _\b4_\b. _\bA_\bd_\bv_\ba_\bn_\bc_\be_\bd _\bU_\bs_\ba_\bg_\be
+ To only print the number of messages if there are new messages in the current mailbox, further extend $status_format to:
+set status_format = "%v on %h: %B %?n?%n new? ...
- _\b4_\b._\b1 _\bR_\be_\bg_\bu_\bl_\ba_\br _\bE_\bx_\bp_\br_\be_\bs_\bs_\bi_\bo_\bn_\bs
+ This feature is called nonzero-printing and works as this: some expandos may be optionally printed nonzero, i.e. a portion of the format string is only evaluated if the value of the expando is different from zero. The basic syntax is:
+%?<item>?<string if nonzero>?
- All string patterns in Mutt-ng including those in more complex _\bp_\ba_\bt_\bt_\be_\br_\bn_\bs (sec-
- tion 7.2 , page 83) must be specified using regular expressions (regexp) in
- the ``POSIX extended'' syntax (which is more or less the syntax used by egrep
- and GNU awk). For your convenience, we have included below a brief description
- of this syntax.
+ which tells mutt-ng to only look at <string if nonzero> if the value of the %<item%gt; expando is different from zero. In our example, we used n as the expando to check for and %n new as the optional nonzero string.
- The search is case sensitive if the pattern contains at least one upper case
- letter, and case insensitive otherwise. Note that ``\'' must be quoted if used
- for a regular expression in an initialization command: ``\\''.
+ But this is not all: this feature only offers one alternative: ``print something if not zero.'' Mutt-ng does, as you might guess, also provide a logically complete version: ``if zero, print something and else print something else.'' This is achieved by the following syntax for those expandos which may be printed nonzero:
+%?<item>?<string if nonzero>&<string if zero>?
- A regular expression is a pattern that describes a set of strings. Regular
- expressions are constructed analogously to arithmetic expressions, by using
- various operators to combine smaller expressions.
+ Using this we can make mutt-ng to do the following:
+ * make it print ``n new messages'' whereby n is the count but only if there new ones
+ * and make it print ``no new messages'' if there aren't any
- Note that the regular expression can be enclosed/delimited by either ' or '
- which is useful if the regular expression includes a white-space character.
- See _\bS_\by_\bn_\bt_\ba_\bx _\bo_\bf _\bI_\bn_\bi_\bt_\bi_\ba_\bl_\bi_\bz_\ba_\bt_\bi_\bo_\bn _\bF_\bi_\bl_\be_\bs (section 3.2 , page 21) for more informa-
- tion on ' and ' delimiter processing. To match a literal ' or ' you must pref-
- ace it with \ (backslash).
+ The corresponding configuration is:
+set status_format = "%v on %h: %B: %?n?%n new messages&no new messages? ...
- The fundamental building blocks are the regular expressions that match a single
- character. Most characters, including all letters and digits, are regular
- expressions that match themselves. Any metacharacter with special meaning may
- be quoted by preceding it with a backslash.
+ This doubles the use of the ``new messages'' string because it'll get always printed. Thus, it can be shortened to:
+set status_format = "%v on %h: %B: %?n?%n&no? new messages ...
- The period ``.'' matches any single character. The caret ``^'' and the dollar
- sign ``$'' are metacharacters that respectively match the empty string at the
- beginning and end of a line.
+ As you might see from this rather simple example, one can create very complex but fancy status messages. Please see the reference chapter for expandos and those which may be printed nonzero.
- A list of characters enclosed by ``['' and ``]'' matches any single character
- in that list; if the first character of the list is a caret ``^'' then it
- matches any character n\bno\bot\bt in the list. For example, the regular expression
- [\b[0\b01\b12\b23\b34\b45\b56\b67\b78\b89\b9]\b] matches any single digit. A range of ASCII characters may be
- specified by giving the first and last characters, separated by a hyphen ``-''.
- Most metacharacters lose their special meaning inside lists. To include a lit-
- eral ``]'' place it first in the list. Similarly, to include a literal ``^''
- place it anywhere but first. Finally, to include a literal hyphen ``-'' place
- it last.
+3.3. Modifications and Padding
- The Mutt Next Generation E-Mail Client 49
+ Besides the information given so far, there're even more features of format strings:
+ * When specifying %_<item> instead of just %<item>, mutt-ng will convert all characters in the expansion of <item> to lowercase.
+ * When specifying %:<item> instead of just %<item>, mutt-ng will convert all dots in the expansion of <item> to underscores (_).
- Certain named classes of characters are predefined. Character classes consist
- of ``[:'', a keyword denoting the class, and ``:]''. The following classes are
- defined by the POSIX standard:
+ Also, there's a feature called Padding supplied by the following two expandos: %|X and %>X.
- [:alnum:]
- Alphanumeric characters.
+ %|X
+ When this occurs, mutt-ng will fill the rest of the line with the character X. In our example, filling the rest of the line with dashes is done by setting:
- [:alpha:]
- Alphabetic characters.
+set status_format = "%v on %h: %B: %?n?%n&no? new messages %|-"
- [:blank:]
- Space or tab characters.
+ %>X
+ Since the previous expando stops at the end of line, there must be a way to fill the gap between two items via the %>X expando: it puts as many characters X in between two items so that the rest of the line will be right-justified. For example, to not put the version string and hostname of our example on the left but on the right and fill the gap with spaces, one might use (note the space after %>):
- [:cntrl:]
- Control characters.
+set status_format = "%B: %?n?%n&no? new messages %> (%v on %h)"
- [:digit:]
- Numeric characters.
+4. Using Tags
- [:graph:]
- Characters that are both printable and visible. (A space is print-
- able, but not visible, while an ``a'' is both.)
+ Sometimes it is desirable to perform an operation on a group of messages all at once rather than one at a time. An example might be to save messages to a mailing list to a separate folder, or to delete all messages with a given subject. To tag all messages matching a pattern, use the tag-pattern function, which is bound to ``shift-T'' by default. Or you can select individual messages by hand using the ``tag-message'' function, which is bound to ``t'' by default. See patterns for Mutt-ng's pattern matching syntax.
- [:lower:]
- Lower-case alphabetic characters.
+ Once you have tagged the desired messages, you can use the ``tag-prefix'' operator, which is the ``;'' (semicolon) key by default. When the ``tag-prefix'' operator is used, the next operation will be applied to all tagged messages if that operation can be used in that manner. If the auto-tag variable is set, the next operation applies to the tagged messages automatically, without requiring the ``tag-prefix''.
- [:print:]
- Printable characters (characters that are not control characters.)
+ In macro or push commands, you can use the ``tag-prefix-cond'' operator. If there are no tagged messages, mutt will "eat" the rest of the macro to abort it's execution. Mutt-ng will stop "eating" the macro when it encounters the ``end-cond'' operator; after this operator the rest of the macro will be executed as normal.
- [:punct:]
- Punctuation characters (characters that are not letter, digits,
- control characters, or space characters).
+5. Using Hooks
- [:space:]
- Space characters (such as space, tab and formfeed, to name a few).
+ A hook is a concept borrowed from the EMACS editor which allows you to execute arbitrary commands before performing some operation. For example, you may wish to tailor your configuration based upon which mailbox you are reading, or to whom you are sending mail. In the Mutt-ng world, a hook consists of a regexp or patterns along with a configuration option/command. See
+ * folder-hook
+ * send-hook
+ * message-hook
+ * save-hook
+ * mbox-hook
+ * fcc-hook
+ * fcc-save-hook
- [:upper:]
- Upper-case alphabetic characters.
+ for specific details on each type of hook available.
- [:xdigit:]
- Characters that are hexadecimal digits.
+ Note: if a hook changes configuration settings, these changes remain effective until the end of the current mutt session. As this is generally not desired, a default hook needs to be added before all other hooks to restore configuration defaults. Here is an example with send-hook and the my_hdr directive:
+send-hook . 'unmy_hdr From:'
+send-hook ~C'^b@b\.b$' my_hdr from: c@c.c
- A character class is only valid in a regular expression inside the brackets of
- a character list. Note that the brackets in these class names are part of the
- symbolic names, and must be included in addition to the brackets delimiting the
- bracket list. For example, [\b[[\b[:\b:d\bdi\big\bgi\bit\bt:\b:]\b]]\b] is equivalent to [\b[0\b0-\b-9\b9]\b].
+5.1. Message Matching in Hooks
- Two additional special sequences can appear in character lists. These apply to
- non-ASCII character sets, which can have single symbols (called collating ele-
- ments) that are represented with more than one character, as well as several
- characters that are equivalent for collating or sorting purposes:
+ Hooks that act upon messages (send-hook, save-hook, fcc-hook, message-hook) are evaluated in a slightly different manner. For the other types of hooks, a regexp is sufficient. But in dealing with messages a finer grain of control is needed for matching since for different purposes you want to match different criteria.
- Collating Symbols
- A collating symbol is a multi-character collating element enclosed
+ Mutt-ng allows the use of the patterns language for matching messages in hook commands. This works in exactly the same way as it would when limiting or searching the mailbox, except that you are restricted to those operators which match information mutt extracts from the header of the message (i.e. from, to, cc, date, subject, etc.).
- The Mutt Next Generation E-Mail Client 50
+ For example, if you wanted to set your return address based upon sending mail to a specific address, you could do something like:
+send-hook '~t ^me@cs\.hmc\.edu$' 'my_hdr From: Mutt-ng User <user@host>'
- in ``[.'' and ``.]''. For example, if ``ch'' is a collating ele-
- ment, then [\b[[\b[.\b.c\bch\bh.\b.]\b]]\b] is a regexp that matches this collating ele-
- ment, while [\b[c\bch\bh]\b] is a regexp that matches either ``c'' or ``h''.
+ which would execute the given command when sending mail to me@cs.hmc.edu.
- Equivalence Classes
- An equivalence class is a locale-specific name for a list of char-
- acters that are equivalent. The name is enclosed in ``[='' and
- ``=]''. For example, the name ``e'' might be used to represent all
- of ``'' ``'' and ``e''. In this case, [\b[[\b[=\b=e\be=\b=]\b]]\b] is a regexp that
- matches any of ``'', ``'' and ``e''.
+ However, it is not required that you write the pattern to match using the full searching language. You can still specify a simple regular expression like the other hooks, in which case Mutt-ng will translate your pattern into the full language, using the translation specified by the default-hook variable. The pattern is translated at the time the hook is declared, so the value of default-hook that is in effect at that time will be used.
- A regular expression matching a single character may be followed by one of sev-
- eral repetition operators:
+6. Using the sidebar
- ?
- The preceding item is optional and matched at most once.
+ The sidebar, a feature specific to Mutt-ng, allows you to use a mailbox listing which looks very similar to the ones you probably know from GUI mail clients. The sidebar lists all specified mailboxes, shows the number in each and highlights the ones with new email Use the following configuration commands:
+set sidebar_visible="yes"
+set sidebar_width=25
- *
- The preceding item will be matched zero or more times.
+ If you want to specify the mailboxes you can do so with:
+set mbox='=INBOX'
+mailboxes INBOX \
+ MBOX1 \
+ MBOX2 \
+ ...
- +
- The preceding item will be matched one or more times.
+ You can also specify the colors for mailboxes with new mails by using:
+color sidebar_new red black
+color sidebar white black
- {n}
- The preceding item is matched exactly _\bn times.
+ The available functions are:
+sidebar-scroll-up Scrolls the mailbox list up 1 page
+sidebar-scroll-down Scrolls the mailbox list down 1 page
+sidebar-next Highlights the next mailbox
+sidebar-next-new Highlights the next mailbox with new mail
+sidebar-previous Highlights the previous mailbox
+sidebar-open Opens the currently highlighted mailbox
- {n,}
- The preceding item is matched _\bn or more times.
+ Reasonable key bindings look e.g. like this:
+bind index \Cp sidebar-prev
+bind index \Cn sidebar-next
+bind index \Cb sidebar-open
+bind pager \Cp sidebar-prev
+bind pager \Cn sidebar-next
+bind pager \Cb sidebar-open
- {,m}
- The preceding item is matched at most _\bm times.
+macro index B ':toggle sidebar_visible^M'
+macro pager B ':toggle sidebar_visible^M'
- {n,m}
- The preceding item is matched at least _\bn times, but no more than _\bm
- times.
+ You can then go up and down by pressing Ctrl-P and Ctrl-N, and switch on and off the sidebar simply by pressing 'B'.
- Two regular expressions may be concatenated; the resulting regular expression
- matches any string formed by concatenating two substrings that respectively
- match the concatenated subexpressions.
+7. External Address Queries
- Two regular expressions may be joined by the infix operator ``|''; the result-
- ing regular expression matches any string matching either subexpression.
+ Mutt-ng supports connecting to external directory databases such as LDAP, ph/qi, bbdb, or NIS through a wrapper script which connects to mutt using a simple interface. Using the query-command variable, you specify the wrapper command to use. For example:
+set query_command = "mutt_ldap_query.pl '%s'"
- Repetition takes precedence over concatenation, which in turn takes precedence
- over alternation. A whole subexpression may be enclosed in parentheses to
- override these precedence rules.
+ The wrapper script should accept the query on the command-line. It should return a one line message, then each matching response on a single line, each line containing a tab separated address then name then some other optional information. On error, or if there are no matching addresses, return a non-zero exit code and a one line error message.
- N\bNo\bot\bte\be:\b: If you compile Mutt-ng with the GNU _\br_\bx package, the following operators
- may also be used in regular expressions:
+ An example multiple response output:
+Searching database ... 20 entries ... 3 matching:
+me@cs.hmc.edu Michael Elkins mutt dude
+blong@fiction.net Brandon Long mutt and more
+roessler@guug.de Thomas Roessler mutt pgp
- \\y
- Matches the empty string at either the beginning or the end of a
- word.
+ There are two mechanisms for accessing the query function of mutt. One is to do a query from the index menu using the query function (default: Q). This will prompt for a query, then bring up the query menu which will list the matching responses. From the query menu, you can select addresses to create aliases, or to mail. You can tag multiple addresses to mail, start a new query, or have a new query appended to the current responses.
- The Mutt Next Generation E-Mail Client 51
+ The other mechanism for accessing the query function is for address completion, similar to the alias completion. In any prompt for address entry, you can use the complete-query function (default: ^T) to run a query based on the current address you have typed. Like aliases, mutt will look for what you have typed back to the last space or comma. If there is a single response for that query, mutt will expand the address in place. If there are multiple responses, mutt will activate the query menu. At the query menu, you can select one or more addresses to be added to the prompt.
- \\B
- Matches the empty string within a word.
+8. Mailbox Formats
- \\<
- Matches the empty string at the beginning of a word.
+ Mutt-ng supports reading and writing of four different mailbox formats: mbox, MMDF, MH and Maildir. The mailbox type is autodetected, so there is no need to use a flag for different mailbox types. When creating new mailboxes, Mutt-ng uses the default specified with the mbox-type variable.
- \\>
- Matches the empty string at the end of a word.
+ mbox. This is the most widely used mailbox format for UNIX. All messages are stored in a single file. Each message has a line of the form:
+From me@cs.hmc.edu Fri, 11 Apr 1997 11:44:56 PST
- \\w
- Matches any word-constituent character (letter, digit, or under-
- score).
+ to denote the start of a new message (this is often referred to as the ``From_'' line).
- \\W
- Matches any character that is not word-constituent.
+ MMDF. This is a variant of the mbox format. Each message is surrounded by lines containing ``^A^A^A^A'' (four control-A's).
- \\`
- Matches the empty string at the beginning of a buffer (string).
+ MH. A radical departure from mbox and MMDF, a mailbox consists of a directory and each message is stored in a separate file. The filename indicates the message number (however, this is may not correspond to the message number Mutt-ng displays). Deleted messages are renamed with a comma (,) prepended to the filename. Note: Mutt detects this type of mailbox by looking for either .mh_sequences or .xmhcache (needed to distinguish normal directories from MH mailboxes).
- \\'
- Matches the empty string at the end of a buffer.
+ Maildir. The newest of the mailbox formats, used by the Qmail MTA (a replacement for sendmail). Similar to MH, except that it adds three subdirectories of the mailbox: tmp, new and cur. Filenames for the messages are chosen in such a way they are unique, even when two programs are writing the mailbox over NFS, which means that no file locking is needed.
- Please note however that these operators are not defined by POSIX, so they may
- or may not be available in stock libraries on various systems.
+9. Mailbox Shortcuts
- _\b4_\b._\b2 _\bP_\ba_\bt_\bt_\be_\br_\bn_\bs
+ There are a number of built in shortcuts which refer to specific mailboxes. These shortcuts can be used anywhere you are prompted for a file or mailbox path.
+ * ! -- refers to your spoolfile (incoming) mailbox
+ * > -- refers to your mbox file
+ * < -- refers to your record file
+ * ^ -- refers to the current mailbox
+ * - or !! -- refers to the file you've last visited
+ * ˜ -- refers to your home directory
+ * = or + -- refers to your folder directory
+ * @alias -- refers to the save-hook as determined by the address of the alias
- Mutt-ng's pattern language provides a simple yet effective way to set up rules
- to match messages, e.g. for operations like tagging and scoring. A pattern con-
- sists of one or more sub-pattern, which can be logically grouped, ORed, and
- negated. For a complete listing of these patterns, please refer to table _\bP_\ba_\bt_\b-
- _\bt_\be_\br_\bn_\bs (section 7.2 , page 83) in the Reference chapter.
+10. Handling Mailing Lists
- It must be noted that in this table, EXPR, USER, ID and SUBJECT are regular
- expressions. For ranges, the forms <[MAX], >>[MIN], [MIN]- and -[MAX] are also
- possible.
+ Mutt-ng has a few configuration options that make dealing with large amounts of mail easier. The first thing you must do is to let Mutt know what addresses you consider to be mailing lists (technically this does not have to be a mailing list, but that is what it is most often used for), and what lists you are subscribed to. This is accomplished through the use of the lists commands in your muttrc.
- _\b4_\b._\b2_\b._\b1 _\bC_\bo_\bm_\bp_\bl_\be_\bx _\bP_\ba_\bt_\bt_\be_\br_\bn_\bs
+ Now that Mutt-ng knows what your mailing lists are, it can do several things, the first of which is the ability to show the name of a list through which you received a message (i.e., of a subscribed list) in the index menu display. This is useful to distinguish between personal and list mail in the same mailbox. In the index-format variable, the escape ``%L'' will return the string ``To <list>'' when ``list'' appears in the ``To'' field, and ``Cc <list>'' when it appears in the ``Cc'' field (otherwise it returns the name of the author).
- It is possible to combine several sub-patterns to a more complex pattern. The
- most simple possibility is to logically AND several patterns by stringing them
- together:
+ Often times the ``To'' and ``Cc'' fields in mailing list messages tend to get quite large. Most people do not bother to remove the author of the message they are reply to from the list, resulting in two or more copies being sent to that person. The ``list-reply'' function, which by default is bound to ``L'' in the index menu and pager, helps reduce the clutter by only replying to the known mailing list addresses instead of all recipients (except as specified by Mail-Followup-To, see below).
- ~s 'SPAM' ~U
+ Mutt-ng also supports the Mail-Followup-To header. When you send a message to a list of recipients which includes one or several subscribed mailing lists, and if the followup-to option is set, mutt will generate a Mail-Followup-To header which contains all the recipients to whom you send this message, but not your address. This indicates that group-replies or list-replies (also known as ``followups'') to this message should only be sent to the original recipients of the message, and not separately to you - you'll receive your copy through one of the mailing lists you are subscribed to.
- The pattern above matches all messages that contain ``SPAM'' in the subject and
- are unread.
+ Conversely, when group-replying or list-replying to a message which has a Mail-Followup-To header, mutt will respect this header if the honor-followup-to configuration variable is set. Using list-reply will in this case also make sure that the reply goes to the mailing list, even if it's not specified in the list of recipients in the Mail-Followup-To.
- To logical OR patterns, simply use the | operator. This one especially useful
- when using local groups:
+ Note that, when header editing is enabled, you can create a Mail-Followup-To header manually. Mutt-ng will only auto-generate this header if it doesn't exist when you send the message.
- The Mutt Next Generation E-Mail Client 52
+ The other method some mailing list admins use is to generate a ``Reply-To'' field which points back to the mailing list address rather than the author of the message. This can create problems when trying to reply directly to the author in private, since most mail clients will automatically reply to the address given in the ``Reply-To'' field. Mutt-ng uses the reply-to variable to help decide which address to use. If set to ask-yes or ask-no, you will be prompted as to whether or not you would like to use the address given in the ``Reply-To'' field, or reply directly to the address given in the ``From'' field. When set to yes, the ``Reply-To'' field will be used when present.
- ~f ("nion@muttng\.org"|"ak@muttng\.org"|"pdmef@muttng\.org")
- (~b mutt-ng|~s Mutt-ng)
- !~x '@synflood\.at'
+ The ``X-Label:'' header field can be used to further identify mailing lists or list subject matter (or just to annotate messages individually). The index-format variable's ``%y'' and ``%Y'' escapes can be used to expand ``X-Label:'' fields in the index, and Mutt-ng's pattern-matcher can match regular expressions to ``X-Label:'' fields with the ``˜y'' selector. ``X-Label:'' is not a standard message header field, but it can easily be inserted by procmail and other mail filtering agents.
- The first pattern matches all messages that were sent by one of the mutt-ng
- maintainers, while the seconds pattern matches all messages that contain
- ``mutt-ng'' in the message body or ``Mutt-ng'' in the subject. The third pat-
- tern matches all messages that do not contain ``@synflood\.at'' in the Refer-
- ences: header, i.e. messages that are not an (indirect) reply to one of my
- messages. A pattern can be logicall negated using the ! operator.
+ Lastly, Mutt-ng has the ability to sort the mailbox into threads. A thread is a group of messages which all relate to the same subject. This is usually organized into a tree-like structure where a message and all of its replies are represented graphically. If you've ever used a threaded news client, this is the same concept. It makes dealing with large volume mailing lists easier because you can easily delete uninteresting threads and quickly find topics of value.

+11. Editing threads
- When using dates in patterns, the dates must be specified in a special format,
- i.e. DD/MM/YYYY. If you don't specify month or year, they default to the cur-
- rent month or year. When using date ranges, and you specify only the minimum or
- the maximum, the specified date will be excluded, e.g. 01/06/2005- matches
- against all messages _\ba_\bf_\bt_\be_\br Juni 1st, 2005.
+ Mutt-ng has the ability to dynamically restructure threads that are broken either by misconfigured software or bad behavior from some correspondents. This allows to clean your mailboxes formats) from these annoyances which make it hard to follow a discussion.
- It is also possible to use so-called ``error margins'' when specifying date
- ranges. You simply specify a date, and then the error margin. This margin
- needs to contain the information whether it goes ``forth'' or ``back'' in time,
- by using + and -. Then follows a number and a unit, i.e. y for years, m for
- months, w for weeks and d for days. If you use the special * sign, it means
- that the error margin goes to both ``directions'' in time.
+11.1. Linking threads
- ~d 01/01/2005+1y
- ~d 18/10/2004-2w
- ~d 28/12/2004*1d
+ Some mailers tend to "forget" to correctly set the "In-Reply-To:" and "References:" headers when replying to a message. This results in broken discussions because Mutt-ng has not enough information to guess the correct threading. You can fix this by tagging the reply, then moving to the parent message and using the ``link-threads'' function (bound to & by default). The reply will then be connected to this "parent" message.
- The first pattern matches all dates between January 1st, 2005 and January 1st
- 2006. The second pattern matches all dates between October 18th, 2004 and
- October 4th 2004 (2 weeks before 18/10/2004), while the third pattern matches
- all dates 1 day around December 28th, 2004 (i.e. Dec 27th, 28th and 29th).
+ You can also connect multiple children at once, tagging them and using the tag-prefix command (';') or the auto_tag option.
- Relative dates are also very important, as they make it possible to specify
- date ranges between a fixed number of units and the current date. How this
- works can be seen in the following example:
+11.2. Breaking threads
- ~d >2w # messages older than two weeks
- ~d <3d # messages newer than 3 days
- ~d =1m # messages that are exactly one month old
+ On mailing lists, some people are in the bad habit of starting a new discussion by hitting "reply" to any message from the list and changing the subject to a totally unrelated one. You can fix such threads by using the ``break-thread'' function (bound by default to #), which will turn the subthread starting from the current message into a whole different thread.

+12. Delivery Status Notification (DSN) Support
- _\b4_\b._\b3_\b._\b1 _\bI_\bn_\bt_\br_\bo_\bd_\bu_\bc_\bt_\bi_\bo_\bn
+ RFC1894 defines a set of MIME content types for relaying information about the status of electronic mail messages. These can be thought of as ``return receipts.''
- The Mutt Next Generation E-Mail Client 53
+ Users can make use of it in one of the following two ways:
+ * Berkeley sendmail 8.8.x currently has some command line options in which the mail client can make requests as to what type of status messages should be returned.
+ * The SMTP support via libESMTP supports it, too.
- The so called _\bF_\bo_\br_\bm_\ba_\bt _\bS_\bt_\br_\bi_\bn_\bg_\bs offer great flexibility when configuring mutt-ng.
- In short, they describe what items to print out how in menus and status mes-
- sages.
+ To support this, there are two variables:
+ * dsn-notify is used to request receipts for different results (such as failed message, message delivered, etc.).
+ * dsn-return requests how much of your message should be returned with the receipt (headers or full message).
- Basically, they work as this: for different menus and bars, there's a variable
- specifying the layout. For every item available, there is a so called _\be_\bx_\bp_\ba_\bn_\bd_\bo.
+ Please see the reference chapter for possible values.
- For example, when running mutt-ng on different machines or different versions
- for testing purposes, it may be interesting to have the following information
- always printed on screen when one is in the index:
+13. POP3 Support (OPTIONAL)
- +\bo the current hostname
+ If Mutt-ng was compiled with POP3 support (by running the configure script with the --enable-pop flag), it has the ability to work with mailboxes located on a remote POP3 server and fetch mail for local browsing.
- +\bo the current mutt-ng version number
+ You can access the remote POP3 mailbox by selecting the folder pop://popserver/.
- The setting for the status bar of the index is controlled via the _\b$_\bs_\bt_\ba_\bt_\bu_\bs_\b__\bf_\bo_\br_\b-
- _\bm_\ba_\bt (section 7.4.315 , page 164) variable. For the hostname and version
- string, there's an expando for $status_format: %h expands to the hostname and
- %v to the version string. When just configuring:
+ You can select an alternative port by specifying it with the server, i.e.: pop://popserver:port/.
- set status_format = "%v on %h: ..."
+ You can also specify different username for each folder, i.e.: pop://username@popserver[:port]/.
- mutt-ng will replace the sequence %v with the version string and %h with the
- host's name. When you are, for example, running mutt-ng version 1.5.9i on host
- mailhost, you'll see the following when you're in the index:
+ Polling for new mail is more expensive over POP3 than locally. For this reason the frequency at which Mutt-ng will check for mail remotely can be controlled by the pop-mail-check variable, which defaults to every 60 seconds.
- Mutt-ng 1.5.9i on mailhost: ...
+ If Mutt-ng was compiled with SSL support (by running the configure script with the --with-ssl flag), connections to POP3 servers can be encrypted. This naturally requires that the server supports SSL encrypted connections. To access a folder with POP3/SSL, you should use pops: prefix, ie: pops://[username@]popserver[:port]/.
- In the index, there're more useful information one could want to see:
+ Another way to access your POP3 mail is the fetch-mail function (default: G). It allows to connect to pop-host, fetch all your new mail and place it in the local spoolfile. After this point, Mutt-ng runs exactly as if the mail had always been local.
- +\bo which mailbox is open
+ Note: If you only need to fetch all messages to local mailbox you should consider using a specialized program, such as fetchmail
- +\bo how man new, flagged or postponed messages
+14. IMAP Support (OPTIONAL)
- +\bo ...
+ If Mutt-ng was compiled with IMAP support (by running the configure script with the --enable-imap flag), it has the ability to work with folders located on a remote IMAP server.
- To include the mailbox' name is as easy as:
+ You can access the remote inbox by selecting the folder imap://imapserver/INBOX, where imapserver is the name of the IMAP server and INBOX is the special name for your spool mailbox on the IMAP server. If you want to access another mail folder at the IMAP server, you should use imap://imapserver/path/to/folder where path/to/folder is the path of the folder you want to access.
- set status_format = "%v on %h: %B: ...
+ You can select an alternative port by specifying it with the server, i.e.: imap://imapserver:port/INBOX.
- When the currently opened mailbox is Inbox, this will be expanded to:
+ You can also specify different username for each folder, i.e.: imap://username@imapserver[:port]/INBOX.
- Mutt-ng 1.5.9i on mailhost: Inbox: ...
+ If Mutt-ng was compiled with SSL support (by running the configure script with the --with-ssl flag), connections to IMAP servers can be encrypted. This naturally requires that the server supports SSL encrypted connections. To access a folder with IMAP/SSL, you should use imaps://[username@]imapserver[:port]/path/to/folder as your folder path.
- For the number of certain types of messages, one more feature of the format
- strings is extremely useful. If there aren't messages of a certain type, it may
+ Pine-compatible notation is also supported, i.e. {[username@]imapserver[:port][/ssl]}path/to/folder
- The Mutt Next Generation E-Mail Client 54
+ Note that not all servers use / as the hierarchy separator. Mutt-ng should correctly notice which separator is being used by the server and convert paths accordingly.
- not be desired to print just that there aren't any but instead only print some-
- thing if there are any.
+ When browsing folders on an IMAP server, you can toggle whether to look at only the folders you are subscribed to, or all folders with the toggle-subscribed command. See also the imap-list-subscribed variable.
- _\b4_\b._\b3_\b._\b2 _\bC_\bo_\bn_\bd_\bi_\bt_\bi_\bo_\bn_\ba_\bl _\bE_\bx_\bp_\ba_\bn_\bs_\bi_\bo_\bn
+ Polling for new mail on an IMAP server can cause noticeable delays. So, you'll want to carefully tune the imap-mail-check and timeout variables.
- To only print the number of messages if there are new messages in the current
- mailbox, further extend $status_format to:
+ Note that if you are using mbox as the mail store on UW servers prior to v12.250, the server has been reported to disconnect a client if another client selects the same folder.
- set status_format = "%v on %h: %B %?n?%n new? ...
+14.1. The Folder Browser
- This feature is called _\bn_\bo_\bn_\bz_\be_\br_\bo_\b-_\bp_\br_\bi_\bn_\bt_\bi_\bn_\bg and works as this: some expandos may be
- optionally printed nonzero, i.e. a portion of the format string is only evalu-
- ated if the value of the expando is different from zero. The basic syntax is:
+ As of version 1.2, mutt supports browsing mailboxes on an IMAP server. This is mostly the same as the local file browser, with the following differences:
+ * Instead of file permissions, mutt displays the string "IMAP", possibly followed by the symbol "+", indicating that the entry contains both messages and subfolders. On Cyrus-like servers folders will often contain both messages and subfolders.
+ * For the case where an entry can contain both messages and subfolders, the selection key (bound to enter by default) will choose to descend into the subfolder view. If you wish to view the messages in that folder, you must use view-file instead (bound to space by default).
+ * You can create, delete and rename mailboxes with the create-mailbox, delete-mailbox, and rename-mailbox commands (default bindings: C, d and r, respectively). You may also subscribe and unsubscribe to mailboxes (normally these are bound to s and u, respectively).
- %?<item>?<string if nonzero>?
+14.2. Authentication
- which tells mutt-ng to only look at <string if nonzero> if the value of the
- %<item%gt; expando is different from zero. In our example, we used n as the
- expando to check for and %n new as the optional nonzero string.
+ Mutt-ng supports four authentication methods with IMAP servers: SASL, GSSAPI, CRAM-MD5, and LOGIN (there is a patch by Grant Edwards to add NTLM authentication for you poor exchange users out there, but it has yet to be integrated into the main tree). There is also support for the pseudo-protocol ANONYMOUS, which allows you to log in to a public IMAP server without having an account. To use ANONYMOUS, simply make your username blank or "anonymous".
- But this is not all: this feature only offers one alternative: ``print some-
- thing if not zero.'' Mutt-ng does, as you might guess, also provide a logically
- complete version: ``if zero, print something and else print something else.''
- This is achieved by the following syntax for those expandos which may be
- printed nonzero:
+ SASL is a special super-authenticator, which selects among several protocols (including GSSAPI, CRAM-MD5, ANONYMOUS, and DIGEST-MD5) the most secure method available on your host and the server. Using some of these methods (including DIGEST-MD5 and possibly GSSAPI), your entire session will be encrypted and invisible to those teeming network snoops. It is the best option if you have it. To use it, you must have the Cyrus SASL library installed on your system and compile mutt with the --with-sasl flag.
- %?<item>?<string if nonzero>&<string if zero>?
+ Mutt-ng will try whichever methods are compiled in and available on the server, in the following order: SASL, ANONYMOUS, GSSAPI, CRAM-MD5, LOGIN.
- Using this we can make mutt-ng to do the following:
+ There are a few variables which control authentication:
+ * imap-user - controls the username under which you request authentication on the IMAP server, for all authenticators. This is overridden by an explicit username in the mailbox path (i.e. by using a mailbox name of the form {user@host}).
+ * imap-pass - a password which you may preset, used by all authentication methods where a password is needed.
+ * imap-authenticators - a colon-delimited list of IMAP authentication methods to try, in the order you wish to try them. If specified, this overrides mutt's default (attempt everything, in the order listed above).
- +\bo make it print ``_\bn new messages'' whereby _\bn is the count but only if there
- new ones
+15. NNTP Support (OPTIONAL)
- +\bo and make it print ``no new messages'' if there aren't any
+ If compiled with ``--enable-nntp'' option, Mutt-ng can read news from a newsserver via NNTP. You can open a newsgroup with the ``change-newsgroup'' function from the index/pager which is by default bound to i.
- The corresponding configuration is:
+ The Default newsserver can be obtained from the $NNTPSERVER environment variable. Like other news readers, info about subscribed newsgroups is saved in a file as specified by the nntp-newsrc variable. Article headers are cached and can be loaded from a file when a newsgroup is entered instead loading from newsserver; currently, this caching mechanism still is different from the header caching for maildir/IMAP.
- set status_format = "%v on %h: %B: %?n?%n new messages&no new messages? ...
+15.1. Again: Scoring
- This doubles the use of the ``new messages'' string because it'll get always
- printed. Thus, it can be shortened to:
+ Especially for Usenet, people often ask for advanced filtering and scoring functionality. Of course, mutt-ng has scoring and allows a killfile, too. How to use a killfile has been discussed in score-command.
- set status_format = "%v on %h: %B: %?n?%n&no? new messages ...
+ What has not been discusses in detail is mutt-ng's built-in realname filter. For may newsreaders including those for ``advanced users'' like slrn or tin, there are frequent request for such functionality. The solutions offered often are complicated regular expressions.
- The Mutt Next Generation E-Mail Client 55
+ In mutt-ng this is as easy as
+score ~* =42
- As you might see from this rather simple example, one can create very complex
- but fancy status messages. Please see the reference chapter for expandos and
- those which may be printed nonzero.
+ This tells mutt-ng to apply a score of 42 to all messages whose sender specified a valid realname and a valid email address. Using
+score !~* =42
- _\b4_\b._\b3_\b._\b3 _\bM_\bo_\bd_\bi_\bf_\bi_\bc_\ba_\bt_\bi_\bo_\bn_\bs _\ba_\bn_\bd _\bP_\ba_\bd_\bd_\bi_\bn_\bg
+ on the contrary applies a score of 42 to all messages not matching those criteria which are very strict:
+ * Email addresses must be valid according to RFC 2822, see <ftp://ftp.rfc-editor.org/in-notes/rfc2822.txt>
+ * the name must consist of at least 2 fields whereby a field must not end in a dot. This means that ``Joe User'' and ``Joe A. User'' are valid while ``J. User'' and ``J. A. User'' aren't.
+ * it's assumed that users are interested in reading their own mail and mail from people who they have defined an alias for so that those 2 groups of messages are excluded from the strict rules.
- Besides the information given so far, there're even more features of format
- strings:
+16. SMTP Support (OPTIONAL)
- +\bo When specifying %_<item> instead of just %<item>, mutt-ng will convert all
- characters in the expansion of <item> to lowercase.
+ Mutt-ng can be built using a library called ``libESMTP'' which provides SMTP functionality. When configure was called with --with-libesmtp or the output muttng -v contains +USE_LIBESMTP, this will be or is the case already. The SMTP support includes support for Delivery Status Notification (see dsn section) as well as handling the 8BITMIME flag controlled via use-8bitmime.
- +\bo When specifying %:<item> instead of just %<item>, mutt-ng will convert all
- dots in the expansion of <item> to underscores (_).
+ To enable sending mail directly via SMTP without an MTA such as Postfix or SSMTP and the like, simply set the smtp-host variable pointing to your SMTP server.
- Also, there's a feature called _\bP_\ba_\bd_\bd_\bi_\bn_\bg supplied by the following two expandos:
- %|X and %>X.
+ Authentication mechanisms are available via the smtp-user and smtp-pass variables.
- %|X
- When this occurs, mutt-ng will fill the rest of the line with the
- character X. In our example, filling the rest of the line with
- dashes is done by setting:
+ Transport Encryption via the StartTLS command is also available. For this to work, first of all Mutt-ng must be built with SSL or GNUTLS. Secondly, the smtp-use-tls variable must be either set to ``enabled'' or ``required.'' In both cases, StartTLS will be used if the server supports it: for the second case, the connection will fail if it doesn't while switching back to unencrypted communication for the first one.
- set status_format = "%v on %h: %B: %?n?%n&no? new messages %|-"
+ Some mail providers require user's to set a particular envelope sender, i.e. they allow for only one value which may not be what the user wants to send as the From: header. In this case, the variable smtp-envelope may be used to set the envelope different from the From: header.
- %>X
- Since the previous expando stops at the end of line, there must be
- a way to fill the gap between two items via the %>X expando: it
- puts as many characters X in between two items so that the rest of
- the line will be right-justified. For example, to not put the ver-
- sion string and hostname of our example on the left but on the
- right and fill the gap with spaces, one might use (note the space
- after %>):
+17. Managing multiple IMAP/POP/NNTP accounts (OPTIONAL)
- set status_format = "%B: %?n?%n&no? new messages %> (%v on %h)"
+ If you happen to have accounts on multiple IMAP and/or POP servers, you may find managing all the authentication settings inconvenient and error-prone. The account-hook command may help. This hook works like folder-hook but is invoked whenever you access a remote mailbox (including inside the folder browser), not just when you open the mailbox.
- _\b4_\b._\b4 _\bU_\bs_\bi_\bn_\bg _\bT_\ba_\bg_\bs
+ Some examples:
+account-hook . 'unset imap_user; unset imap_pass; unset tunnel'
+account-hook imap://host1/ 'set imap_user=me1 imap_pass=foo'
+account-hook imap://host2/ 'set tunnel="ssh host2 /usr/libexec/imapd"'
- Sometimes it is desirable to perform an operation on a group of messages all at
- once rather than one at a time. An example might be to save messages to a
- mailing list to a separate folder, or to delete all messages with a given sub-
- ject. To tag all messages matching a pattern, use the tag-pattern function,
- which is bound to ``shift-T'' by default. Or you can select individual mes-
- sages by hand using the ``tag-message'' function, which is bound to ``t'' by
+18. Start a WWW Browser on URLs (EXTERNAL)
- The Mutt Next Generation E-Mail Client 56
+ If a message contains URLs (unified resource locator = address in the WWW space like http://www.mutt.org/), it is efficient to get a menu with all the URLs and start a WWW browser on one of them. This functionality is provided by the external urlview program which can be retrieved at ftp://ftp.mutt.org/mutt/contrib/ and the configuration commands:
+macro index \cb |urlview\n
+macro pager \cb |urlview\n
- default. See _\bp_\ba_\bt_\bt_\be_\br_\bn_\bs (section 7.2 , page 83) for Mutt-ng's pattern matching
- syntax.
+19. Compressed folders Support (OPTIONAL)
- Once you have tagged the desired messages, you can use the ``tag-prefix'' oper-
- ator, which is the ``;'' (semicolon) key by default. When the ``tag-prefix''
- operator is used, the n\bne\bex\bxt\bt operation will be applied to all tagged messages if
- that operation can be used in that manner. If the _\b$_\ba_\bu_\bt_\bo_\b__\bt_\ba_\bg (section 7.4.19 ,
- page 93) variable is set, the next operation applies to the tagged messages
- automatically, without requiring the ``tag-prefix''.
+ If Mutt-ng was compiled with compressed folders support (by running the configure script with the --enable-compressed flag), Mutt can open folders stored in an arbitrary format, provided that the user has a script to convert from/to this format to one of the accepted.
- In _\bm_\ba_\bc_\br_\bo_\bs (section 3.8 , page 29) or _\bp_\bu_\bs_\bh (section 3.24 , page 40) commands,
- you can use the ``tag-prefix-cond'' operator. If there are no tagged messages,
- mutt will "eat" the rest of the macro to abort it's execution. Mutt-ng will
- stop "eating" the macro when it encounters the ``end-cond'' operator; after
- this operator the rest of the macro will be executed as normal.
+ The most common use is to open compressed archived folders e.g. with gzip.
- _\b4_\b._\b5 _\bU_\bs_\bi_\bn_\bg _\bH_\bo_\bo_\bk_\bs
+ In addition, the user can provide a script that gets a folder in an accepted format and appends its context to the folder in the user-defined format, which may be faster than converting the entire folder to the accepted format, appending to it and converting back to the user-defined format.
- A _\bh_\bo_\bo_\bk is a concept borrowed from the EMACS editor which allows you to execute
- arbitrary commands before performing some operation. For example, you may wish
- to tailor your configuration based upon which mailbox you are reading, or to
- whom you are sending mail. In the Mutt-ng world, a _\bh_\bo_\bo_\bk consists of a _\br_\be_\bg_\bu_\bl_\ba_\br
- _\be_\bx_\bp_\br_\be_\bs_\bs_\bi_\bo_\bn (section 4.1 , page 48) or _\bp_\ba_\bt_\bt_\be_\br_\bn (section 7.2 , page 83) along
- with a configuration option/command. See
+ There are three hooks defined (open-hook, close-hook and append-hook) which define commands to uncompress and compress a folder and to append messages to an existing compressed folder respectively.
- +\bo _\bf_\bo_\bl_\bd_\be_\br_\b-_\bh_\bo_\bo_\bk (section 3.7 , page 28)
+ For example:
+open-hook \\.gz$ "gzip -cd %f > %t"
+close-hook \\.gz$ "gzip -c %t > %f"
+append-hook \\.gz$ "gzip -c %t >> %f"
- +\bo _\bs_\be_\bn_\bd_\b-_\bh_\bo_\bo_\bk (section 3.21 , page 39)
+ You do not have to specify all of the commands. If you omit append-hook, the folder will be open and closed again each time you will add to it. If you omit close-hook (or give empty command) , the folder will be open in the mode. If you specify append-hook though you'll be able to append to the folder.
- +\bo _\bm_\be_\bs_\bs_\ba_\bg_\be_\b-_\bh_\bo_\bo_\bk (section 3.22 , page 40)
+ Note that Mutt-ng will only try to use hooks if the file is not in one of the accepted formats. In particular, if the file is empty, mutt supposes it is not compressed. This is important because it allows the use of programs that do not have well defined extensions. Just use "." as a regexp. But this may be surprising if your compressing script produces empty files. In this situation, unset save-empty, so that the compressed file will be removed if you delete all of the messages.

+ Usage: open-hook regexp "command"

+ The command is the command that can be used for opening the folders whose names match regexp.
- +\bo _\bf_\bc_\bc_\b-_\bs_\ba_\bv_\be_\b-_\bh_\bo_\bo_\bk (section 3.20 , page 39)
+ The command string is the printf-like format string, and it should accept two parameters: %f, which is replaced with the (compressed) folder name, and %t which is replaced with the name of the temporary folder to which to write.
- for specific details on each type of _\bh_\bo_\bo_\bk available.
+ %f and %t can be repeated any number of times in the command string, and all of the entries are replaced with the appropriate folder name. In addition, %% is replaced by %, as in printf, and any other %anything is left as is.
- N\bNo\bot\bte\be:\b: if a hook changes configuration settings, these changes remain effective
- until the end of the current mutt session. As this is generally not desired, a
- default hook needs to be added before all other hooks to restore configuration
- defaults. Here is an example with send-hook and the my_hdr directive:
+ The command should not remove the original compressed file. The command should return non-zero exit status if it fails, so mutt knows something's wrong.
- send-hook . 'unmy_hdr From:'
- send-hook ~C'^b@b\.b$' my_hdr from: c@c.c
+ Example:
+open-hook \\.gz$ "gzip -cd %f > %t"
- The Mutt Next Generation E-Mail Client 57
+ If the command is empty, this operation is disabled for this file type.

+19.2. Write a compressed mailbox
- Hooks that act upon messages (send-hook, save-hook, fcc-hook, message-hook) are
- evaluated in a slightly different manner. For the other types of hooks, a _\br_\be_\bg_\b-
- _\bu_\bl_\ba_\br _\be_\bx_\bp_\br_\be_\bs_\bs_\bi_\bo_\bn (section 4.1 , page 48) is sufficient. But in dealing with
- messages a finer grain of control is needed for matching since for different
- purposes you want to match different criteria.
+ Usage: close-hook regexp "command"
- Mutt-ng allows the use of the _\bs_\be_\ba_\br_\bc_\bh _\bp_\ba_\bt_\bt_\be_\br_\bn (section 7.2 , page 83) language
- for matching messages in hook commands. This works in exactly the same way as
- it would when _\bl_\bi_\bm_\bi_\bt_\bi_\bn_\bg or _\bs_\be_\ba_\br_\bc_\bh_\bi_\bn_\bg the mailbox, except that you are restricted
- to those operators which match information mutt extracts from the header of the
- message (i.e. from, to, cc, date, subject, etc.).
+ This is used to close the folder that was open with the open-hook command after some changes were made to it.
- For example, if you wanted to set your return address based upon sending mail
- to a specific address, you could do something like:
+ The command string is the command that can be used for closing the folders whose names match regexp. It has the same format as in the open-hook command. Temporary folder in this case is the folder previously produced by the <open-hook command.
- send-hook '~t ^me@cs\.hmc\.edu$' 'my_hdr From: Mutt-ng User <user@host>'
+ The command should not remove the decompressed file. The command should return non-zero exit status if it fails, so mutt knows something's wrong.
- which would execute the given command when sending mail to _\bm_\be_\b@_\bc_\bs_\b._\bh_\bm_\bc_\b._\be_\bd_\bu.
+ Example:
+close-hook \\.gz$ "gzip -c %t > %f"
- However, it is not required that you write the pattern to match using the full
- searching language. You can still specify a simple _\br_\be_\bg_\bu_\bl_\ba_\br _\be_\bx_\bp_\br_\be_\bs_\bs_\bi_\bo_\bn like the
- other hooks, in which case Mutt-ng will translate your pattern into the full
- language, using the translation specified by the _\b$_\bd_\be_\bf_\ba_\bu_\bl_\bt_\b__\bh_\bo_\bo_\bk (section
- 7.4.49 , page 100) variable. The pattern is translated at the time the hook
- is declared, so the value of _\b$_\bd_\be_\bf_\ba_\bu_\bl_\bt_\b__\bh_\bo_\bo_\bk (section 7.4.49 , page 100) that is
- in effect at that time will be used.
+ If the command is empty, this operation is disabled for this file type, and the file can only be open in the readonly mode.
- _\b4_\b._\b6 _\bU_\bs_\bi_\bn_\bg _\bt_\bh_\be _\bs_\bi_\bd_\be_\bb_\ba_\br
+ close-hook is not called when you exit from the folder if the folder was not changed.
- The sidebar, a feature specific to Mutt-ng, allows you to use a mailbox listing
- which looks very similar to the ones you probably know from GUI mail clients.
- The sidebar lists all specified mailboxes, shows the number in each and high-
- lights the ones with new email Use the following configuration commands:
+19.3. Append a message to a compressed mailbox
- set sidebar_visible="yes"
- set sidebar_width=25
+ Usage: append-hook regexp "command"
- If you want to specify the mailboxes you can do so with:
+ This command is used for saving to an existing compressed folder. The command is the command that can be used for appending to the folders whose names match regexp. It has the same format as in the open-hook command. The temporary folder in this case contains the messages that are being appended.
- set mbox='=INBOX'
- mailboxes INBOX \
- MBOX1 \
- MBOX2 \
- ...
+ The command should not remove the decompressed file. The command should return non-zero exit status if it fails, so mutt knows something's wrong.
- You can also specify the colors for mailboxes with new mails by using:
+ Example:
+append-hook \\.gz$ "gzip -c %t >> %f"
- The Mutt Next Generation E-Mail Client 58
+ When append-hook is used, the folder is not opened, which saves time, but this means that we can not find out what the folder type is. Thus the default (mbox-type) type is always supposed (i.e. this is the format used for the temporary folder).
- color sidebar_new red black
- color sidebar white black
+ If the file does not exist when you save to it, close-hook is called, and not append-hook. append-hook is only for appending to existing folders.
- The available functions are:
+ If the command is empty, this operation is disabled for this file type. In this case, the folder will be open and closed again (using open-hook and close-hookrespectively) each time you will add to it.
- sidebar-scroll-up Scrolls the mailbox list up 1 page
- sidebar-scroll-down Scrolls the mailbox list down 1 page
- sidebar-next Highlights the next mailbox
- sidebar-next-new Highlights the next mailbox with new mail
- sidebar-previous Highlights the previous mailbox
- sidebar-open Opens the currently highlighted mailbox
+19.4. Encrypted folders
- Reasonable key bindings look e.g. like this:
+ The compressed folders support can also be used to handle encrypted folders. If you want to encrypt a folder with PGP, you may want to use the following hooks:
+open-hook \\.pgp$ "pgp -f < %f > %t"
+close-hook \\.pgp$ "pgp -fe YourPgpUserIdOrKeyId < %t > %f"
- bind index \Cp sidebar-prev
- bind index \Cn sidebar-next
- bind index \Cb sidebar-open
- bind pager \Cp sidebar-prev
- bind pager \Cn sidebar-next
- bind pager \Cb sidebar-open
+ Please note, that PGP does not support appending to an encrypted folder, so there is no append-hook defined.
- macro index B ':toggle sidebar_visible^M'
- macro pager B ':toggle sidebar_visible^M'
+ Note: the folder is temporary stored decrypted in the /tmp directory, where it can be read by your system administrator. So think about the security aspects of this.
- You can then go up and down by pressing Ctrl-P and Ctrl-N, and switch on and
- off the sidebar simply by pressing 'B'.

- simple interface. Using the _\b$_\bq_\bu_\be_\br_\by_\b__\bc_\bo_\bm_\bm_\ba_\bn_\bd (section 7.4.228 , page 144) vari-

+ Quite a bit of effort has been made to make Mutt-ng the premier text-mode MIME MUA. Every effort has been made to provide the functionality that the discerning MIME user requires, and the conformance to the standards wherever possible. When configuring Mutt-ng for MIME, there are two extra types of configuration files which Mutt-ng uses. One is the mime.types file, which contains the mapping of file extensions to IANA MIME types. The other is the mailcap file, which specifies the external commands to use for handling specific MIME types.
- roessler@guug.de Thomas Roessler mutt pgp
+1. Using MIME in Mutt
- There are two mechanisms for accessing the query function of mutt. One is to
- do a query from the index menu using the query function (default: Q). This
- will prompt for a query, then bring up the query menu which will list the
- matching responses. From the query menu, you can select addresses to create
- aliases, or to mail. You can tag multiple addresses to mail, start a new
- query, or have a new query appended to the current responses.
+ There are three areas/menus in Mutt-ng which deal with MIME, they are the pager (while viewing a message), the attachment menu and the compose menu.
- The other mechanism for accessing the query function is for address completion,
- similar to the alias completion. In any prompt for address entry, you can use
- the complete-query function (default: ^T) to run a query based on the current
- address you have typed. Like aliases, mutt will look for what you have typed
- back to the last space or comma. If there is a single response for that query,
- mutt will expand the address in place. If there are multiple responses, mutt
- will activate the query menu. At the query menu, you can select one or more
- addresses to be added to the prompt.
+1.1. Viewing MIME messages in the pager
- _\b4_\b._\b8 _\bM_\ba_\bi_\bl_\bb_\bo_\bx _\bF_\bo_\br_\bm_\ba_\bt_\bs
+ When you select a message from the index and view it in the pager, Mutt decodes the message to a text representation. Mutt-ng internally supports a number of MIME types, including text/plain, text/enriched, message/rfc822, and message/news. In addition, the export controlled version of Mutt-ng recognizes a variety of PGP MIME types, including PGP/MIME and application/pgp.
- Mutt-ng supports reading and writing of four different mailbox formats: mbox,
- MMDF, MH and Maildir. The mailbox type is autodetected, so there is no need to
- use a flag for different mailbox types. When creating new mailboxes, Mutt-ng
- uses the default specified with the _\b$_\bm_\bb_\bo_\bx_\b__\bt_\by_\bp_\be (section 7.4.132 , page 121)
- variable.
+ Mutt-ng will denote attachments with a couple lines describing them. These lines are of the form:
+[-- Attachment #1: Description --]
+[-- Type: text/plain, Encoding: 7bit, Size: 10000 --]
- m\bmb\bbo\box\bx. This is the most widely used mailbox format for UNIX. All messages are
- stored in a single file. Each message has a line of the form:
+ Where the Description is the description or filename given for the attachment, and the Encoding is one of 7bit/8bit/quoted-printable/base64/binary.
- From me@cs.hmc.edu Fri, 11 Apr 1997 11:44:56 PST
+ If Mutt-ng cannot deal with a MIME type, it will display a message like:
+[-- image/gif is unsupported (use 'v' to view this part) --]
- to denote the start of a new message (this is often referred to as the
- ``From_'' line).
+1.2. The Attachment Menu
- M\bMM\bMD\bDF\bF. This is a variant of the _\bm_\bb_\bo_\bx format. Each message is surrounded by
- lines containing ``^A^A^A^A'' (four control-A's).
+ The default binding for view-attachments is `v', which displays the attachment menu for a message. The attachment menu displays a list of the attachments in a message. From the attachment menu, you can save, print, pipe, delete, and view attachments. You can apply these operations to a group of attachments at once, by tagging the attachments and by using the ``tag-prefix'' operator. You can also reply to the current message from this menu, and only the current attachment (or the attachments tagged) will be quoted in your reply. You can view attachments as text, or view them using the mailcap viewer definition.
- M\bMH\bH. A radical departure from _\bm_\bb_\bo_\bx and _\bM_\bM_\bD_\bF, a mailbox consists of a directory
- and each message is stored in a separate file. The filename indicates the mes-
- sage number (however, this is may not correspond to the message number Mutt-ng
- displays). Deleted messages are renamed with a comma (,) prepended to the file-
- name. N\bNo\bot\bte\be:\b: Mutt detects this type of mailbox by looking for either
- .mh_sequences or .xmhcache (needed to distinguish normal directories from MH
- mailboxes).
+ Finally, you can apply the usual message-related functions (like resend-message, and the reply and forward functions) to attachments of type message/rfc822.
- M\bMa\bai\bil\bld\bdi\bir\br. The newest of the mailbox formats, used by the Qmail MTA (a replace-
- ment for sendmail). Similar to _\bM_\bH, except that it adds three subdirectories of
- the mailbox: _\bt_\bm_\bp, _\bn_\be_\bw and _\bc_\bu_\br. Filenames for the messages are chosen in such a
- way they are unique, even when two programs are writing the mailbox over NFS,
-
- The Mutt Next Generation E-Mail Client 60
-
- which means that no file locking is needed.
-
- _\b4_\b._\b9 _\bM_\ba_\bi_\bl_\bb_\bo_\bx _\bS_\bh_\bo_\br_\bt_\bc_\bu_\bt_\bs
-
- There are a number of built in shortcuts which refer to specific mailboxes.
- These shortcuts can be used anywhere you are prompted for a file or mailbox
- path.
+ See the help on the attachment menu for more information.
- +\bo ! -- refers to your _\b$_\bs_\bp_\bo_\bo_\bl_\bf_\bi_\bl_\be (section 7.4.304 , page 162) (incoming)

-
- +\bo < -- refers to your _\b$_\br_\be_\bc_\bo_\br_\bd (section 7.4.237 , page 146) file
+1.3. The Compose Menu
- +\bo ^ -- refers to the current mailbox
+ The compose menu is the menu you see before you send a message. It allows you to edit the recipient list, the subject, and other aspects of your message. It also contains a list of the attachments of your message, including the main body. From this menu, you can print, copy, filter, pipe, edit, compose, review, and rename an attachment or a list of tagged attachments. You can also modifying the attachment information, notably the type, encoding and description.
- +\bo - or !! -- refers to the file you've last visited
+ Attachments appear as follows:
+- 1 [text/plain, 7bit, 1K] /tmp/mutt-euler-8082-0 <no description>
+ 2 [applica/x-gunzip, base64, 422K] ~/src/mutt-0.85.tar.gz <no description>
- +\bo ~ -- refers to your home directory
+ The '-' denotes that Mutt-ng will delete the file after sending (or postponing, or canceling) the message. It can be toggled with the toggle-unlink command (default: u). The next field is the MIME content-type, and can be changed with the edit-type command (default: ^T). The next field is the encoding for the attachment, which allows a binary message to be encoded for transmission on 7bit links. It can be changed with the edit-encoding command (default: ^E). The next field is the size of the attachment, rounded to kilobytes or megabytes. The next field is the filename, which can be changed with the rename-file command (default: R). The final field is the description of the attachment, and can be changed with the edit-description command (default: d).
- +\bo = or + -- refers to your _\b$_\bf_\bo_\bl_\bd_\be_\br (section 7.4.70 , page 104) directory

- determined by the address of the alias
+2. MIME Type configuration with mime.types
- _\b4_\b._\b1_\b0 _\bH_\ba_\bn_\bd_\bl_\bi_\bn_\bg _\bM_\ba_\bi_\bl_\bi_\bn_\bg _\bL_\bi_\bs_\bt_\bs
-
- Mutt-ng has a few configuration options that make dealing with large amounts of
- mail easier. The first thing you must do is to let Mutt know what addresses
- you consider to be mailing lists (technically this does not have to be a mail-
- ing list, but that is what it is most often used for), and what lists you are
- subscribed to. This is accomplished through the use of the _\bl_\bi_\bs_\bt_\bs _\ba_\bn_\bd _\bs_\bu_\bb_\bs_\bc_\br_\bi_\bb_\be
- (section 3.13 , page 35) commands in your muttrc.
-
- Now that Mutt-ng knows what your mailing lists are, it can do several things,
- the first of which is the ability to show the name of a list through which you
- received a message (i.e., of a subscribed list) in the _\bi_\bn_\bd_\be_\bx menu display.
- This is useful to distinguish between personal and list mail in the same mail-
- box. In the _\b$_\bi_\bn_\bd_\be_\bx_\b__\bf_\bo_\br_\bm_\ba_\bt (section 7.4.116 , page 115) variable, the escape
- ``%L'' will return the string ``To <list>'' when ``list'' appears in the ``To''
- field, and ``Cc <list>'' when it appears in the ``Cc'' field (otherwise it
- returns the name of the author).
+ When you add an attachment to your mail message, Mutt-ng searches your personal mime.types file at ${HOME}/.mime.types, and then the system mime.types file at /usr/local/share/mutt/mime.types or /etc/mime.types
- Often times the ``To'' and ``Cc'' fields in mailing list messages tend to get
- quite large. Most people do not bother to remove the author of the message they
- are reply to from the list, resulting in two or more copies being sent to that
- person. The ``list-reply'' function, which by default is bound to ``L'' in the
- _\bi_\bn_\bd_\be_\bx menu and _\bp_\ba_\bg_\be_\br, helps reduce the clutter by only replying to the known
- mailing list addresses instead of all recipients (except as specified by Mail-
+ The mime.types file consist of lines containing a MIME type and a space separated list of extensions. For example:
+application/postscript ps eps
+application/pgp pgp
+audio/x-aiff aif aifc aiff
- The Mutt Next Generation E-Mail Client 61
+ A sample mime.types file comes with the Mutt-ng distribution, and should contain most of the MIME types you are likely to use.
- Followup-To, see below).
+ If Mutt-ng can not determine the mime type by the extension of the file you attach, it will look at the file. If the file is free of binary information, Mutt-ng will assume that the file is plain text, and mark it as text/plain. If the file contains binary information, then Mutt-ng will mark it as application/octet-stream. You can change the MIME type that Mutt-ng assigns to an attachment by using the edit-type command from the compose menu (default: ^T). The MIME type is actually a major mime type followed by the sub-type, separated by a '/'. 6 major types: application, text, image, video, audio, and model have been approved after various internet discussions. Mutt-ng recognises all of these if the appropriate entry is found in the mime.types file. It also recognises other major mime types, such as the chemical type that is widely used in the molecular modelling community to pass molecular data in various forms to various molecular viewers. Non-recognised mime types should only
+ be used if the recipient of the message is likely to be expecting such attachments.
- Mutt-ng also supports the Mail-Followup-To header. When you send a message to
- a list of recipients which includes one or several subscribed mailing lists,
- and if the _\b$_\bf_\bo_\bl_\bl_\bo_\bw_\bu_\bp_\b__\bt_\bo (section 7.4.72 , page 105) option is set, mutt will
- generate a Mail-Followup-To header which contains all the recipients to whom
- you send this message, but not your address. This indicates that group-replies
- or list-replies (also known as ``followups'') to this message should only be
- sent to the original recipients of the message, and not separately to you -
- you'll receive your copy through one of the mailing lists you are subscribed
- to.
+3. MIME Viewer configuration with mailcap
- Conversely, when group-replying or list-replying to a message which has a Mail-
- Followup-To header, mutt will respect this header if the _\b$_\bh_\bo_\bn_\bo_\br_\b__\bf_\bo_\bl_\bl_\bo_\bw_\bu_\bp_\b__\bt_\bo
- (section 7.4.94 , page 110) configuration variable is set. Using list-reply
- will in this case also make sure that the reply goes to the mailing list, even
- if it's not specified in the list of recipients in the Mail-Followup-To.
+ Mutt-ng supports RFC 1524 MIME Configuration, in particular the Unix specific format specified in Appendix A of RFC 1524. This file format is commonly referred to as the mailcap format. Many MIME compliant programs utilize the mailcap format, allowing you to specify handling for all MIME types in one place for all programs. Programs known to use this format include Netscape, XMosaic, lynx and metamail.
- Note that, when header editing is enabled, you can create a Mail-Followup-To
- header manually. Mutt-ng will only auto-generate this header if it doesn't
- exist when you send the message.
+ In order to handle various MIME types that Mutt-ng can not handle internally, Mutt-ng parses a series of external configuration files to find an external handler. The default search string for these files is a colon delimited list set to
+${HOME}/.mailcap:/usr/local/share/mutt/mailcap:/etc/mailcap:/etc/mailcap:/usr/etc/mailcap:/usr/local/etc/mailcap
- The other method some mailing list admins use is to generate a ``Reply-To''
- field which points back to the mailing list address rather than the author of
- the message. This can create problems when trying to reply directly to the
- author in private, since most mail clients will automatically reply to the
- address given in the ``Reply-To'' field. Mutt-ng uses the _\b$_\br_\be_\bp_\bl_\by_\b__\bt_\bo (section
- 7.4.240 , page 147) variable to help decide which address to use. If set to
- _\ba_\bs_\bk_\b-_\by_\be_\bs or _\ba_\bs_\bk_\b-_\bn_\bo, you will be prompted as to whether or not you would like to
- use the address given in the ``Reply-To'' field, or reply directly to the
- address given in the ``From'' field. When set to _\by_\be_\bs, the ``Reply-To'' field
- will be used when present.
+ where $HOME is your home directory.
- The ``X-Label:'' header field can be used to further identify mailing lists or
- list subject matter (or just to annotate messages individually). The
- _\b$_\bi_\bn_\bd_\be_\bx_\b__\bf_\bo_\br_\bm_\ba_\bt (section 7.4.116 , page 115) variable's ``%y'' and ``%Y''
- escapes can be used to expand ``X-Label:'' fields in the index, and Mutt-ng's
- pattern-matcher can match regular expressions to ``X-Label:'' fields with the
- ``~y'' selector. ``X-Label:'' is not a standard message header field, but it
- can easily be inserted by procmail and other mail filtering agents.
+ In particular, the metamail distribution will install a mailcap file, usually as /usr/local/etc/mailcap, which contains some baseline entries.
- Lastly, Mutt-ng has the ability to _\bs_\bo_\br_\bt (section 7.4.298 , page 160) the mail-
- box into _\bt_\bh_\br_\be_\ba_\bd_\bs (section 2.5.3 , page 11). A thread is a group of messages
- which all relate to the same subject. This is usually organized into a tree-
- like structure where a message and all of its replies are represented graphi-
- cally. If you've ever used a threaded news client, this is the same concept.
- It makes dealing with large volume mailing lists easier because you can easily
- delete uninteresting threads and quickly find topics of value.
+3.1. The Basics of the mailcap file
- _\b4_\b._\b1_\b1 _\bE_\bd_\bi_\bt_\bi_\bn_\bg _\bt_\bh_\br_\be_\ba_\bd_\bs
+ A mailcap file consists of a series of lines which are comments, blank, or definitions.
- Mutt-ng has the ability to dynamically restructure threads that are broken
+ A comment line consists of a # character followed by anything you want.
- The Mutt Next Generation E-Mail Client 62
+ A blank line is blank.
- either by misconfigured software or bad behavior from some correspondents. This
- allows to clean your mailboxes formats) from these annoyances which make it
- hard to follow a discussion.
+ A definition line consists of a content type, a view command, and any number of optional fields. Each field of a definition line is divided by a semicolon ';' character.
- _\b4_\b._\b1_\b1_\b._\b1 _\bL_\bi_\bn_\bk_\bi_\bn_\bg _\bt_\bh_\br_\be_\ba_\bd_\bs
+ The content type is specified in the MIME standard type/subtype method. For example, text/plain, text/html, image/gif, etc. In addition, the mailcap format includes two formats for wildcards, one using the special '*' subtype, the other is the implicit wild, where you only include the major type. For example, image/*, or video, will match all image types and video types, respectively.
- Some mailers tend to "forget" to correctly set the "In-Reply-To:" and "Refer-
- ences:" headers when replying to a message. This results in broken discussions
- because Mutt-ng has not enough information to guess the correct threading. You
- can fix this by tagging the reply, then moving to the parent message and using
- the ``link-threads'' function (bound to & by default). The reply will then be
- connected to this "parent" message.
+ The view command is a Unix command for viewing the type specified. There are two different types of commands supported. The default is to send the body of the MIME message to the command on stdin. You can change this behavior by using %s as a parameter to your view command. This will cause Mutt-ng to save the body of the MIME message to a temporary file, and then call the view command with the %s replaced by the name of the temporary file. In both cases, Mutt-ng will turn over the terminal to the view program until the program quits, at which time Mutt will remove the temporary file if it exists.
- You can also connect multiple children at once, tagging them and using the tag-
- prefix command (';') or the auto_tag option.
+ So, in the simplest form, you can send a text/plain message to the external pager more on stdin:
+text/plain; more
- _\b4_\b._\b1_\b1_\b._\b2 _\bB_\br_\be_\ba_\bk_\bi_\bn_\bg _\bt_\bh_\br_\be_\ba_\bd_\bs
+ Or, you could send the message as a file:
+text/plain; more %s
- On mailing lists, some people are in the bad habit of starting a new discussion
- by hitting "reply" to any message from the list and changing the subject to a
- totally unrelated one. You can fix such threads by using the ``break-thread''
- function (bound by default to #), which will turn the subthread starting from
- the current message into a whole different thread.
+ Perhaps you would like to use lynx to interactively view a text/html message:
+text/html; lynx %s
- _\b4_\b._\b1_\b2 _\bD_\be_\bl_\bi_\bv_\be_\br_\by _\bS_\bt_\ba_\bt_\bu_\bs _\bN_\bo_\bt_\bi_\bf_\bi_\bc_\ba_\bt_\bi_\bo_\bn _\b(_\bD_\bS_\bN_\b) _\bS_\bu_\bp_\bp_\bo_\br_\bt
+ In this case, lynx does not support viewing a file from stdin, so you must use the %s syntax. Note: Some older versions of lynx contain a bug where they will check the mailcap file for a viewer for text/html. They will find the line which calls lynx, and run it. This causes lynx to continuously spawn itself to view the object.
- RFC1894 defines a set of MIME content types for relaying information about the
- status of electronic mail messages. These can be thought of as ``return
- receipts.''
+ On the other hand, maybe you don't want to use lynx interactively, you just want to have it convert the text/html to text/plain, then you can use:
+text/html; lynx -dump %s | more
- Users can make use of it in one of the following two ways:
+ Perhaps you wish to use lynx to view text/html files, and a pager on all other text formats, then you would use the following:
+text/html; lynx %s
+text/*; more
- +\bo Berkeley sendmail 8.8.x currently has some command line options in which
- the mail client can make requests as to what type of status messages
- should be returned.
+ This is the simplest form of a mailcap file.
- +\bo The SMTP support via libESMTP supports it, too.
+3.2. Secure use of mailcap
- To support this, there are two variables:
+ The interpretation of shell meta-characters embedded in MIME parameters can lead to security problems in general. Mutt-ng tries to quote parameters in expansion of %s syntaxes properly, and avoids risky characters by substituting them, see the mailcap-sanitize variable.
- +\bo _\b$_\bd_\bs_\bn_\b__\bn_\bo_\bt_\bi_\bf_\by (section 7.4.56 , page 101) is used to request receipts for
- different results (such as failed message, message delivered, etc.).
+ Although mutt's procedures to invoke programs with mailcap seem to be safe, there are other applications parsing mailcap, maybe taking less care of it. Therefore you should pay attention to the following rules:
- +\bo _\b$_\bd_\bs_\bn_\b__\br_\be_\bt_\bu_\br_\bn (section 7.4.57 , page 102) requests how much of your message
- should be returned with the receipt (headers or full message).
+ Keep the %-expandos away from shell quoting. Don't quote them with single or double quotes. Mutt-ng does this for you, the right way, as should any other program which interprets mailcap. Don't put them into backtick expansions. Be highly careful with eval statements, and avoid them if possible at all. Trying to fix broken behaviour with quotes introduces new leaks - there is no alternative to correct quoting in the first place.
- Please see the reference chapter for possible values.
+ If you have to use the %-expandos' values in context where you need quoting or backtick expansions, put that value into a shell variable and reference the shell variable where necessary, as in the following example (using $charset inside the backtick expansion is safe, since it is not itself subject to any further expansion):
+text/test-mailcap-bug; cat %s; copiousoutput; test=charset=%{charset} \
+ && test "`echo $charset | tr '[A-Z]' '[a-z]'`" != iso-8859-1
- _\b4_\b._\b1_\b3 _\bP_\bO_\bP_\b3 _\bS_\bu_\bp_\bp_\bo_\br_\bt _\b(_\bO_\bP_\bT_\bI_\bO_\bN_\bA_\bL_\b)
+3.3. Advanced mailcap Usage
- The Mutt Next Generation E-Mail Client 63
+3.3.1. Optional Fields
- If Mutt-ng was compiled with POP3 support (by running the _\bc_\bo_\bn_\bf_\bi_\bg_\bu_\br_\be script with
- the _\b-_\b-_\be_\bn_\ba_\bb_\bl_\be_\b-_\bp_\bo_\bp flag), it has the ability to work with mailboxes located on a
- remote POP3 server and fetch mail for local browsing.
+ In addition to the required content-type and view command fields, you can add semi-colon ';' separated fields to set flags and other options. Mutt-ng recognizes the following optional fields:
- You can access the remote POP3 mailbox by selecting the folder
- pop://popserver/.
+ copiousoutput
+ This flag tells Mutt-ng that the command passes possibly large amounts of text on stdout. This causes Mutt-ng to invoke a pager (either the internal pager or the external pager defined by the pager variable) on the output of the view command. Without this flag, Mutt-ng assumes that the command is interactive. One could use this to replace the pipe to more in the lynx -dump example in the Basic section:
- You can select an alternative port by specifying it with the server, i.e.:
- pop://popserver:port/.
+text/html; lynx -dump %s ; copiousoutput
- You can also specify different username for each folder, i.e.: pop://user-
- name@popserver[:port]/.
+ This will cause lynx to format the text/html output as text/plain and Mutt-ng will use your standard pager to display the results.
- Polling for new mail is more expensive over POP3 than locally. For this reason
- the frequency at which Mutt-ng will check for mail remotely can be controlled
- by the _\b$_\bp_\bo_\bp_\b__\bm_\ba_\bi_\bl_\b__\bc_\bh_\be_\bc_\bk (section 7.4.215 , page 141) variable, which defaults
- to every 60 seconds.
+ needsterminal
+ Mutt-ng uses this flag when viewing attachments with auto-view, in order to decide whether it should honor the setting of the wait-key variable or not. When an attachment is viewed using an interactive program, and the corresponding mailcap entry has a needsterminal flag, Mutt-ng will use wait-key and the exit status of the program to decide if it will ask you to press a key after the external program has exited. In all other situations it will not prompt you for a key.
- If Mutt-ng was compiled with SSL support (by running the _\bc_\bo_\bn_\bf_\bi_\bg_\bu_\br_\be script with
- the _\b-_\b-_\bw_\bi_\bt_\bh_\b-_\bs_\bs_\bl flag), connections to POP3 servers can be encrypted. This natu-
- rally requires that the server supports SSL encrypted connections. To access a
- folder with POP3/SSL, you should use pops: prefix, ie: pops://[user-
- name@]popserver[:port]/.
+ compose=<command>
+ This flag specifies the command to use to create a new attachment of a specific MIME type. Mutt-ng supports this from the compose menu.
- Another way to access your POP3 mail is the _\bf_\be_\bt_\bc_\bh_\b-_\bm_\ba_\bi_\bl function (default: G).
- It allows to connect to _\bp_\bo_\bp_\b__\bh_\bo_\bs_\bt (section 7.4.213 , page 141), fetch all your
- new mail and place it in the local _\bs_\bp_\bo_\bo_\bl_\bf_\bi_\bl_\be (section 7.4.304 , page 162).
- After this point, Mutt-ng runs exactly as if the mail had always been local.
+ composetyped=<command>
+ This flag specifies the command to use to create a new attachment of a specific MIME type. This command differs from the compose command in that mutt will expect standard MIME headers on the data. This can be used to specify parameters, filename, description, etc. for a new attachment. Mutt-ng supports this from the compose menu.
- N\bNo\bot\bte\be:\b: If you only need to fetch all messages to local mailbox you should con-
- sider using a specialized program, such as fetchmail
+ print=<command>
+ This flag specifies the command to use to print a specific MIME type. Mutt-ng supports this from the attachment and compose menus.
- _\b4_\b._\b1_\b4 _\bI_\bM_\bA_\bP _\bS_\bu_\bp_\bp_\bo_\br_\bt _\b(_\bO_\bP_\bT_\bI_\bO_\bN_\bA_\bL_\b)
+ edit=<command>
+ This flag specifies the command to use to edit a specific MIME type. Mutt-ng supports this from the compose menu, and also uses it to compose new attachments. Mutt-ng will default to the defined editor for text attachments.
- If Mutt-ng was compiled with IMAP support (by running the _\bc_\bo_\bn_\bf_\bi_\bg_\bu_\br_\be script with
- the _\b-_\b-_\be_\bn_\ba_\bb_\bl_\be_\b-_\bi_\bm_\ba_\bp flag), it has the ability to work with folders located on a
- remote IMAP server.
+ nametemplate=<template>
+ This field specifies the format for the file denoted by %s in the command fields. Certain programs will require a certain file extension, for instance, to correctly view a file. For instance, lynx will only interpret a file as text/html if the file ends in .html. So, you would specify lynx as a text/html viewer with a line in the mailcap file like:
- You can access the remote inbox by selecting the folder
- imap://imapserver/INBOX, where imapserver is the name of the IMAP server and
- INBOX is the special name for your spool mailbox on the IMAP server. If you
- want to access another mail folder at the IMAP server, you should use
- imap://imapserver/path/to/folder where path/to/folder is the path of the folder
- you want to access.
+text/html; lynx %s; nametemplate=%s.html
- You can select an alternative port by specifying it with the server, i.e.:
- imap://imapserver:port/INBOX.
+ test=<command>
+ This field specifies a command to run to test whether this mailcap entry should be used. The command is defined with the command expansion rules defined in the next section. If the command returns 0, then the test passed, and Mutt-ng uses this entry. If the command returns non-zero, then the test failed, and Mutt-ng continues searching for the right entry. Note: the content-type must match before Mutt-ng performs the test. For example:
- You can also specify different username for each folder, i.e.: imap://user-
- name@imapserver[:port]/INBOX.
+text/html; netscape -remote 'openURL(%s)' ; test=RunningX
+text/html; lynx %s
- If Mutt-ng was compiled with SSL support (by running the _\bc_\bo_\bn_\bf_\bi_\bg_\bu_\br_\be script with
+ In this example, Mutt-ng will run the program RunningX which will return 0 if the X Window manager is running, and non-zero if it isn't. If RunningX returns 0, then Mutt-ng will call netscape to display the text/html object. If RunningX doesn't return 0, then Mutt-ng will go on to the next entry and use lynx to display the text/html object.

+3.3.2. Search Order
- the _\b-_\b-_\bw_\bi_\bt_\bh_\b-_\bs_\bs_\bl flag), connections to IMAP servers can be encrypted. This natu-
- rally requires that the server supports SSL encrypted connections. To access a
- folder with IMAP/SSL, you should use imaps://[user-
- name@]imapserver[:port]/path/to/folder as your folder path.
+ When searching for an entry in the mailcap file, Mutt-ng will search for the most useful entry for its purpose. For instance, if you are attempting to print an image/gif, and you have the following entries in your mailcap file, Mutt-ng will search for an entry with the print command:
+image/*; xv %s
+image/gif; ; print= anytopnm %s | pnmtops | lpr; \
+ nametemplate=%s.gif
- Pine-compatible notation is also supported, i.e. {[user-
- name@]imapserver[:port][/ssl]}path/to/folder
+ Mutt-ng will skip the image/* entry and use the image/gif entry with the print command.
- Note that not all servers use / as the hierarchy separator. Mutt-ng should
- correctly notice which separator is being used by the server and convert paths
- accordingly.
+ In addition, you can use this with auto-view to denote two commands for viewing an attachment, one to be viewed automatically, the other to be viewed interactively from the attachment menu. In addition, you can then use the test feature to determine which viewer to use interactively depending on your environment.
+text/html; netscape -remote 'openURL(%s)' ; test=RunningX
+text/html; lynx %s; nametemplate=%s.html
+text/html; lynx -dump %s; nametemplate=%s.html; copiousoutput
- When browsing folders on an IMAP server, you can toggle whether to look at only
- the folders you are subscribed to, or all folders with the _\bt_\bo_\bg_\bg_\bl_\be_\b-_\bs_\bu_\bb_\bs_\bc_\br_\bi_\bb_\be_\bd
- command. See also the _\b$_\bi_\bm_\ba_\bp_\b__\bl_\bi_\bs_\bt_\b__\bs_\bu_\bb_\bs_\bc_\br_\bi_\bb_\be_\bd (section 7.4.103 , page 113)
- variable.
+ For auto-view, Mutt-ng will choose the third entry because of the copiousoutput tag. For interactive viewing, Mutt will run the program RunningX to determine if it should use the first entry. If the program returns non-zero, Mutt-ng will use the second entry for interactive viewing.
- Polling for new mail on an IMAP server can cause noticeable delays. So, you'll
- want to carefully tune the _\b$_\bi_\bm_\ba_\bp_\b__\bm_\ba_\bi_\bl_\b__\bc_\bh_\be_\bc_\bk (section 7.4.105 , page 113) and
- _\b$_\bt_\bi_\bm_\be_\bo_\bu_\bt (section 7.4.328 , page 169) variables.
+3.3.3. Command Expansion
- Note that if you are using mbox as the mail store on UW servers prior to
- v12.250, the server has been reported to disconnect a client if another client
- selects the same folder.
+ The various commands defined in the mailcap files are passed to the /bin/sh shell using the system() function. Before the command is passed to /bin/sh -c, it is parsed to expand various special parameters with information from Mutt-ng. The keywords Mutt-ng expands are:
- _\b4_\b._\b1_\b4_\b._\b1 _\bT_\bh_\be _\bF_\bo_\bl_\bd_\be_\br _\bB_\br_\bo_\bw_\bs_\be_\br
+ %s
+ As seen in the basic mailcap section, this variable is expanded to a filename specified by the calling program. This file contains the body of the message to view/print/edit or where the composing program should place the results of composition. In addition, the use of this keyword causes Mutt-ng to not pass the body of the message to the view/print/edit program on stdin.
- As of version 1.2, mutt supports browsing mailboxes on an IMAP server. This is
- mostly the same as the local file browser, with the following differences:
+ %t
+ Mutt-ng will expand %t to the text representation of the content type of the message in the same form as the first parameter of the mailcap definition line, ie text/html or image/gif.
- +\bo Instead of file permissions, mutt displays the string "IMAP", possibly
- followed by the symbol "+", indicating that the entry contains both mes-
- sages and subfolders. On Cyrus-like servers folders will often contain
- both messages and subfolders.
+ %{<parameter>}
+ Mutt-ng will expand this to the value of the specified parameter from the Content-Type: line of the mail message. For instance, if Your mail message contains:
- +\bo For the case where an entry can contain both messages and subfolders, the
- selection key (bound to enter by default) will choose to descend into the
- subfolder view. If you wish to view the messages in that folder, you must
- use view-file instead (bound to space by default).
+Content-Type: text/plain; charset=iso-8859-1
- +\bo You can create, delete and rename mailboxes with the create-mailbox,
- delete-mailbox, and rename-mailbox commands (default bindings: C, d and r,
- respectively). You may also subscribe and unsubscribe to mailboxes (nor-
- mally these are bound to s and u, respectively).
+ then Mutt-ng will expand %{charset} to iso-8859-1. The default metamail mailcap file uses this feature to test the charset to spawn an xterm using the right charset to view the message.
- _\b4_\b._\b1_\b4_\b._\b2 _\bA_\bu_\bt_\bh_\be_\bn_\bt_\bi_\bc_\ba_\bt_\bi_\bo_\bn
+ \%
+ This will be replaced by a %
- Mutt-ng supports four authentication methods with IMAP servers: SASL, GSSAPI,
- CRAM-MD5, and LOGIN (there is a patch by Grant Edwards to add NTLM authentica-
- tion for you poor exchange users out there, but it has yet to be integrated
- into the main tree). There is also support for the pseudo-protocol ANONYMOUS,
- which allows you to log in to a public IMAP server without having an account.
- To use ANONYMOUS, simply make your username blank or "anonymous".
+ Mutt-ng does not currently support the %F and %n keywords specified in RFC 1524. The main purpose of these parameters is for multipart messages, which is handled internally by Mutt-ng.
- The Mutt Next Generation E-Mail Client 65
+3.4. Example mailcap files
- SASL is a special super-authenticator, which selects among several protocols
- (including GSSAPI, CRAM-MD5, ANONYMOUS, and DIGEST-MD5) the most secure method
- available on your host and the server. Using some of these methods (including
- DIGEST-MD5 and possibly GSSAPI), your entire session will be encrypted and
- invisible to those teeming network snoops. It is the best option if you have
- it. To use it, you must have the Cyrus SASL library installed on your system
- and compile mutt with the _\b-_\b-_\bw_\bi_\bt_\bh_\b-_\bs_\ba_\bs_\bl flag.
+ This mailcap file is fairly simple and standard:
+>
+# I'm always running X :)
+video/*; xanim %s > /dev/null
+image/*; xv %s > /dev/null
- Mutt-ng will try whichever methods are compiled in and available on the server,
- in the following order: SASL, ANONYMOUS, GSSAPI, CRAM-MD5, LOGIN.
+# I'm always running netscape (if my computer had more memory, maybe)
+text/html; netscape -remote 'openURL(%s)'
- There are a few variables which control authentication:
+ This mailcap file shows quite a number of examples:
+# Use xanim to view all videos Xanim produces a header on startup,
+# send that to /dev/null so I don't see it
+video/*; xanim %s > /dev/null
- +\bo _\b$_\bi_\bm_\ba_\bp_\b__\bu_\bs_\be_\br (section 7.4.111 , page 114) - controls the username under
- which you request authentication on the IMAP server, for all authentica-
- tors. This is overridden by an explicit username in the mailbox path (i.e.
- by using a mailbox name of the form {user@host}).
+# Send html to a running netscape by remote
+text/html; netscape -remote 'openURL(%s)'; test=RunningNetscape
- +\bo _\b$_\bi_\bm_\ba_\bp_\b__\bp_\ba_\bs_\bs (section 7.4.106 , page 113) - a password which you may pre-
- set, used by all authentication methods where a password is needed.
+# If I'm not running netscape but I am running X, start netscape on the
+# object
+text/html; netscape %s; test=RunningX
- +\bo _\b$_\bi_\bm_\ba_\bp_\b__\ba_\bu_\bt_\bh_\be_\bn_\bt_\bi_\bc_\ba_\bt_\bo_\br_\bs (section 7.4.97 , page 111) - a colon-delimited list
- of IMAP authentication methods to try, in the order you wish to try them.
- If specified, this overrides mutt's default (attempt everything, in the
- order listed above).

- If compiled with ``--enable-nntp'' option, Mutt-ng can read news from a
- newsserver via NNTP. You can open a newsgroup with the ``change-newsgroup''
- function from the index/pager which is by default bound to i.
+# I use enscript to print text in two columns to a page
+text/*; more %s; print=enscript -2Gr %s
- The Default newsserver can be obtained from the $NNTPSERVER environment vari-
- able. Like other news readers, info about subscribed newsgroups is saved in a
- file as specified by the _\b$_\bn_\bn_\bt_\bp_\b__\bn_\be_\bw_\bs_\br_\bc (section 7.4.163 , page 129) variable.
- Article headers are cached and can be loaded from a file when a newsgroup is
- entered instead loading from newsserver; currently, this caching mechanism
- still is different from the header caching for maildir/IMAP.

- Especially for Usenet, people often ask for advanced filtering and scoring
- functionality. Of course, mutt-ng has scoring and allows a killfile, too. How
- to use a killfile has been discussed in _\bM_\be_\bs_\bs_\ba_\bg_\be _\bs_\bc_\bo_\br_\bi_\bn_\bg (section 3.26 , page
- 41).

- What has not been discusses in detail is mutt-ng's built-in realname filter.
- For may newsreaders including those for ``advanced users'' like _\bs_\bl_\br_\bn or _\bt_\bi_\bn,
- there are frequent request for such functionality. The solutions offered often
- are complicated regular expressions.

+4. MIME Autoview
- The Mutt Next Generation E-Mail Client 66
+ In addition to explicitly telling Mutt-ng to view an attachment with the MIME viewer defined in the mailcap file, Mutt-ng has support for automatically viewing MIME attachments while in the pager.
- score ~* =42
+ To work, you must define a viewer in the mailcap file which uses the copiousoutput option to denote that it is non-interactive. Usually, you also use the entry to convert the attachment to a text representation which you can view in the pager.
- This tells mutt-ng to apply a score of 42 to all messages whose sender speci-
- fied a valid realname and a valid email address. Using
+ You then use the auto_view muttrc command to list the content-types that you wish to view automatically.
- score !~* =42
+ For instance, if you set auto_view to:
+auto_view text/html application/x-gunzip application/postscript image/gif application/x-tar-gz
- on the contrary applies a score of 42 to all messages _\bn_\bo_\bt matching those crite-
- ria which are very strict:
+ Mutt-ng could use the following mailcap entries to automatically view attachments of these types.
+text/html; lynx -dump %s; copiousoutput; nametemplate=%s.html
+image/*; anytopnm %s | pnmscale -xsize 80 -ysize 50 | ppmtopgm | pgmtopbm | pbmtoascii ; copiousoutput
+application/x-gunzip; gzcat; copiousoutput
+application/x-tar-gz; gunzip -c %s | tar -tf - ; copiousoutput
+application/postscript; ps2ascii %s; copiousoutput
- +\bo Email addresses must be valid according to RFC 2822, see <ftp://ftp.rfc-
- editor.org/in-notes/rfc2822.txt>
+ ``unauto_view'' can be used to remove previous entries from the autoview list. This can be used with message-hook to autoview messages based on size, etc. ``unauto_view *'' will remove all previous entries.
- +\bo the name must consist of at least 2 fields whereby a field must not end in
- a dot. This means that ``Joe User'' and ``Joe A. User'' are valid while
- ``J. User'' and ``J. A. User'' aren't.
+5. MIME Multipart/Alternative
- +\bo it's assumed that users are interested in reading their own mail and mail
- from people who they have defined an alias for so that those 2 groups of
- messages are excluded from the strict rules.
+ Mutt-ng has some heuristics for determining which attachment of a multipart/alternative type to display. First, mutt will check the alternative_order list to determine if one of the available types is preferred. The alternative_order list consists of a number of MIME types in order, including support for implicit and explicit wildcards, for example:
+alternative_order text/enriched text/plain text application/postscript image/*
- _\b4_\b._\b1_\b6 _\bS_\bM_\bT_\bP _\bS_\bu_\bp_\bp_\bo_\br_\bt _\b(_\bO_\bP_\bT_\bI_\bO_\bN_\bA_\bL_\b)
+ Next, mutt will check if any of the types have a defined auto-view, and use that. Failing that, Mutt-ng will look for any text type. As a last attempt, mutt will look for any type it knows how to handle.
- Mutt-ng can be built using a library called ``libESMTP'' which provides SMTP
- functionality. When configure was called with --with-libesmtp or the output
- muttng -v contains +USE_LIBESMTP, this will be or is the case already. The SMTP
- support includes support for Delivery Status Notification (see _\bD_\be_\bl_\bi_\bv_\be_\br_\by _\bS_\bt_\ba_\bt_\bu_\bs
- _\bN_\bo_\bt_\bi_\bf_\bi_\bc_\ba_\bt_\bi_\bo_\bn (section 4.12 , page 62) section) as well as handling the 8BIT-
- MIME flag controlled via _\b$_\bu_\bs_\be_\b__\b8_\bb_\bi_\bt_\bm_\bi_\bm_\be (section 7.4.335 , page 171).
+ To remove a MIME type from the alternative_order list, use the unalternative_order command.
- To enable sending mail directly via SMTP without an MTA such as Postfix or
- SSMTP and the like, simply set the _\b$_\bs_\bm_\bt_\bp_\b__\bh_\bo_\bs_\bt (section 7.4.293 , page 159)
- variable pointing to your SMTP server.
+6. MIME Lookup
- Authentication mechanisms are available via the _\b$_\bs_\bm_\bt_\bp_\b__\bu_\bs_\be_\br (section 7.4.297 ,
- page 160) and _\b$_\bs_\bm_\bt_\bp_\b__\bp_\ba_\bs_\bs (section 7.4.294 , page 159) variables.
+ Mutt-ng's mime_lookup list specifies a list of mime-types that should not be treated according to their mailcap entry. This option is designed to deal with binary types such as application/octet-stream. When an attachment's mime-type is listed in mime_lookup, then the extension of the filename will be compared to the list of extensions in the mime.types file. The mime-type associated with this extension will then be used to process the attachment according to the rules in the mailcap file and according to any other configuration options (such as auto_view) specified. Common usage would be:
+mime_lookup application/octet-stream application/X-Lotus-Manuscript
- Transport Encryption via the StartTLS command is also available. For this to
- work, first of all Mutt-ng must be built with SSL or GNUTLS. Secondly, the
- _\b$_\bs_\bm_\bt_\bp_\b__\bu_\bs_\be_\b__\bt_\bl_\bs (section 7.4.296 , page 160) variable must be either set to
- ``enabled'' or ``required.'' In both cases, StartTLS will be used if the server
- supports it: for the second case, the connection will fail if it doesn't while
- switching back to unencrypted communication for the first one.
+ In addition, the unmime_lookup command may be used to disable this feature for any particular mime-type if it had been set, for example, in a global muttrc.
- Some mail providers require user's to set a particular envelope sender, i.e.
+Chapter 6. Security Considerations

- they allow for only one value which may not be what the user wants to send as
- the From: header. In this case, the variable _\b$_\bs_\bm_\bt_\bp_\b__\be_\bn_\bv_\be_\bl_\bo_\bp_\be (section 7.4.292 ,
- page 159) may be used to set the envelope different from the From: header.

- If a message contains URLs (_\bu_\bn_\bi_\bf_\bi_\be_\bd _\br_\be_\bs_\bo_\bu_\br_\bc_\be _\bl_\bo_\bc_\ba_\bt_\bo_\br = address in the WWW space
- like _\bh_\bt_\bt_\bp_\b:_\b/_\b/_\bw_\bw_\bw_\b._\bm_\bu_\bt_\bt_\b._\bo_\br_\bg_\b/), it is efficient to get a menu with all the URLs and
- start a WWW browser on one of them. This functionality is provided by the
- external urlview program which can be retrieved at ftp://ftp.mutt.org/mutt/con-
- trib/ and the configuration commands:
+ When configuring mutt-ng, there're some points to note about secure setups.
- macro index \cb |urlview\n
- macro pager \cb |urlview\n
+ In practice, mutt-ng can be easily made as vulnerable as even the most insecure mail user agents (in their default configuration) just by changing mutt-ng's configuration files: it then can execute arbitrary programs and scripts attached to messages, send out private data on its own, etc. Although this is not believed to the common type of setup, please read this chapter carefully.
- _\b4_\b._\b1_\b9 _\bC_\bo_\bm_\bp_\br_\be_\bs_\bs_\be_\bd _\bf_\bo_\bl_\bd_\be_\br_\bs _\bS_\bu_\bp_\bp_\bo_\br_\bt _\b(_\bO_\bP_\bT_\bI_\bO_\bN_\bA_\bL_\b)
+1. Passwords
- If Mutt-ng was compiled with compressed folders support (by running the _\bc_\bo_\bn_\bf_\bi_\bg_\b-
- _\bu_\br_\be script with the _\b-_\b-_\be_\bn_\ba_\bb_\bl_\be_\b-_\bc_\bo_\bm_\bp_\br_\be_\bs_\bs_\be_\bd flag), Mutt can open folders stored in
- an arbitrary format, provided that the user has a script to convert from/to
- this format to one of the accepted.
+ Although mutt-ng can be told the various passwords for accounts, please never store passwords in configuration files. Besides the fact that the system's operator can always read them, you could forget to replace the actual password with asterisks when reporting a bug or asking for help via, for example, a mailing list so that your mail including your password could be archived by internet search engines, etc. Please never store passwords on disk.
- The most common use is to open compressed archived folders e.g. with gzip.
+2. Temporary Files
- In addition, the user can provide a script that gets a folder in an accepted
- format and appends its context to the folder in the user-defined format, which
- may be faster than converting the entire folder to the accepted format, append-
- ing to it and converting back to the user-defined format.
+ Mutt-ng uses many temporary files for viewing messages, verifying digital signatures, etc. The umask variable can be used to change the default permissions of these files. Please only change it if you really know what you are doing. Also, a different location for these files may be desired which can be changed via the tmpdir variable.
- There are three hooks defined (_\bo_\bp_\be_\bn_\b-_\bh_\bo_\bo_\bk (section 4.19.1 , page 68), _\bc_\bl_\bo_\bs_\be_\b-
- _\bh_\bo_\bo_\bk (section 4.19.2 , page 68) and _\ba_\bp_\bp_\be_\bn_\bd_\b-_\bh_\bo_\bo_\bk (section 4.19.3 , page 69))
- which define commands to uncompress and compress a folder and to append mes-
- sages to an existing compressed folder respectively.
+3. Information Leaks
- The Mutt Next Generation E-Mail Client 68
+3.1. Message-ID: headers
- For example:
+ In the default configuration, mutt-ng will leak some information to the outside world when sending messages: the generation of Message-ID: headers includes a step counter which is increased (and rotated) with every message sent. If you'd like to hide this information probably telling others how many mail you sent in which time, you at least need to remove the %P expando from the default setting of the msgid-format variable. Please make sure that you really know how local parts of these Message-ID: headers are composed.
- open-hook \\.gz$ "gzip -cd %f > %t"
- close-hook \\.gz$ "gzip -c %t > %f"
- append-hook \\.gz$ "gzip -c %t >> %f"
+3.2. mailto:-style links
- You do not have to specify all of the commands. If you omit _\ba_\bp_\bp_\be_\bn_\bd_\b-_\bh_\bo_\bo_\bk (sec-
- tion 4.19.3 , page 69), the folder will be open and closed again each time you
- will add to it. If you omit _\bc_\bl_\bo_\bs_\be_\b-_\bh_\bo_\bo_\bk (section 4.19.2 , page 68) (or give
- empty command) , the folder will be open in the mode. If you specify _\ba_\bp_\bp_\be_\bn_\bd_\b-
- _\bh_\bo_\bo_\bk (section 4.19.3 , page 69) though you'll be able to append to the folder.
+ As mutt-ng be can be set up to be the mail client to handle mailto: style links in websites, there're security considerations, too. To keep the old behavior by default, mutt-ng will be strict in interpreting them which means that arbitrary header fields can be embedded in these links which could override existing header fields or attach arbitrary files. This may be problematic if the edit-headers variable is unset, i.e. the user doesn't want to see header fields while editing the message.
- Note that Mutt-ng will only try to use hooks if the file is not in one of the
- accepted formats. In particular, if the file is empty, mutt supposes it is not
- compressed. This is important because it allows the use of programs that do not
- have well defined extensions. Just use '.' as a regexp. But this may be sur-
- prising if your compressing script produces empty files. In this situation,
- unset _\b$_\bs_\ba_\bv_\be_\b__\be_\bm_\bp_\bt_\by (section 7.4.247 , page 148), so that the compressed file
- will be removed if you delete all of the messages.
+ For example, following a link like
+mailto:joe@host?Attach=~/.gnupg/secring.gpg
- _\b4_\b._\b1_\b9_\b._\b1 _\bO_\bp_\be_\bn _\ba _\bc_\bo_\bm_\bp_\br_\be_\bs_\bs_\be_\bd _\bm_\ba_\bi_\bl_\bb_\bo_\bx _\bf_\bo_\br _\br_\be_\ba_\bd_\bi_\bn_\bg
+ will send out the user's private gnupg keyring to joe@host if the user doesn't follow the information on screen carefully enough.
- Usage: open-hook _\br_\be_\bg_\be_\bx_\bp '_\bc_\bo_\bm_\bm_\ba_\bn_\bd'
+ When unsetting the strict-mailto variable, mutt-ng will
+ * be less strict when interpreting these links by prepending a X-Mailto- string to all header fields embedded in such a link and
+ * turn on the edit-headers variable by force to let the user see all the headers (because they still may leak information.)
- The _\bc_\bo_\bm_\bm_\ba_\bn_\bd is the command that can be used for opening the folders whose names
- match _\br_\be_\bg_\be_\bx_\bp.
+4. External applications
- The _\bc_\bo_\bm_\bm_\ba_\bn_\bd string is the printf-like format string, and it should accept two
- parameters: %f, which is replaced with the (compressed) folder name, and %t
- which is replaced with the name of the temporary folder to which to write.
+ Mutt-ng in many places has to rely on external applications or for convenience supports mechanisms involving external applications.
- %f and %t can be repeated any number of times in the command string, and all of
- the entries are replaced with the appropriate folder name. In addition, %% is
- replaced by %, as in printf, and any other %anything is left as is.
+4.1. mailcap
- The _\bc_\bo_\bm_\bm_\ba_\bn_\bd should n\bno\bot\bt remove the original compressed file. The _\bc_\bo_\bm_\bm_\ba_\bn_\bd should
- return non-zero exit status if it fails, so mutt knows something's wrong.
+ One of these is the mailcap mechanism as defined by RfC 1524. Mutt-ng can be set up to automatically execute any given utility as listed in one of the mailcap files (see the mailcap-path variable for details.)
- Example:
+ These utilities may have a variety of security vulnerabilities, including overwriting of arbitrary files, information leaks or other exploitable bugs. These vulnerabilities may go unnoticed by the user, especially when they are called automatically (and without interactive prompting) from the mailcap file(s). When using mutt-ng's autoview mechanism in combination with mailcap files, please be sure to...
+ * manually select trustworth applications with a reasonable calling sequence
+ * periodically check the contents of mailcap files, especially after software installations or upgrades
+ * keep the software packages referenced in the mailcap file up to date
+ * leave the mailcap-sanitize variable in its default state to restrict mailcap expandos to a safe set of characters
- open-hook \\.gz$ "gzip -cd %f > %t"
+4.2. Other
- If the _\bc_\bo_\bm_\bm_\ba_\bn_\bd is empty, this operation is disabled for this file type.
+ Besides the mailcap mechanism, mutt-ng uses a number of other external utilities for operation.
- _\b4_\b._\b1_\b9_\b._\b2 _\bW_\br_\bi_\bt_\be _\ba _\bc_\bo_\bm_\bp_\br_\be_\bs_\bs_\be_\bd _\bm_\ba_\bi_\bl_\bb_\bo_\bx
+ The same security considerations apply for these as for tools involved via mailcap (for example, mutt-ng is vulnerable to Denial of Service Attacks with compressed folders support if the uncompressed mailbox is too large for the disk it is saved to.)
- Usage: close-hook _\br_\be_\bg_\be_\bx_\bp '_\bc_\bo_\bm_\bm_\ba_\bn_\bd'
+ As already noted, most of these problems are not built in but caused by wrong configuration, so please check your configuration.
- This is used to close the folder that was open with the _\bo_\bp_\be_\bn_\b-_\bh_\bo_\bo_\bk (section
- 4.19.1 , page 68) command after some changes were made to it.

- close-hook \\.gz$ "gzip -c %t > %f"
+ Running mutt with no arguments will make Mutt-ng attempt to read your spool mailbox. However, it is possible to read other mailboxes and to send messages from the command line as well.
+-A expand an alias
+-a attach a file to a message
+-b specify a blind carbon-copy (BCC) address
+-c specify a carbon-copy (Cc) address
+-e specify a config command to be run after initialization files are read
+-f specify a mailbox to load
+-F specify an alternate file to read initialization commands
+-h print help on command line options
+-H specify a draft file from which to read a header and body
+-i specify a file to include in a message composition
+-m specify a default mailbox type
+-n do not read the system Muttngrc
+-p recall a postponed message
+-Q query a configuration variable
+-R open mailbox in read-only mode
+-s specify a subject (enclose in quotes if it contains spaces)
+-t dump the value of all variables to stdout
+-T dump the value of all changed variables to stdout
+-v show version number and compile-time definitions
+-x simulate the mailx(1) compose mode
+-y show a menu containing the files specified by the mailboxes command
+-z exit immediately if there are no messages in the mailbox
+-Z open the first folder with new message,exit immediately if none
+
+ To read messages in a mailbox
+
+ mutt [ -nz ] [ -F muttrc ] [ -m type ] [ -f mailbox ]
+
+ To compose a new message
+
+ mutt [ -n ] [ -F muttrc ] [ -a file ] [ -c address ] [ -i filename ] [ -s subject ] address [ address ... ]
+
+ Mutt-ng also supports a ``batch'' mode to send prepared messages. Simply redirect input from the file you wish to send. For example,
+
+ mutt -s "data set for run #2" professor@bigschool.edu < ˜/run2.dat
+
+ This command will send a message to ``professor@bigschool.edu'' with a subject of ``data set for run #2''. In the body of the message will be the contents of the file ``˜/run2.dat''.
+
+2. Patterns
+
+~A all messages
+~b EXPR messages which contain EXPR in the message body
+~B EXPR messages which contain EXPR in the whole message
+~c USER messages carbon-copied to USER
+~C EXPR message is either to: or cc: EXPR
+~D deleted messages
+~d [MIN]-[MAX] messages with ``date-sent'' in a Date range
+~E expired messages
+~e EXPR message which contains EXPR in the ``Sender'' field
+~F flagged messages
+~f USER messages originating from USER
+~g cryptographically signed messages
+~G cryptographically encrypted messages
+~H EXPR messages with a spam attribute matching EXPR
+~h EXPR messages which contain EXPR in the message header
+~k message contains PGP key material
+~i ID message which match ID in the ``Message-ID'' field
+~L EXPR message is either originated or received by EXPR
+~l message is addressed to a known mailing list
+~m [MIN]-[MAX] message in the range MIN to MAX *)
+~M multipart messages
+~n [MIN]-[MAX] messages with a score in the range MIN to MAX *)
+~N new messages
+~O old messages
+~p message is addressed to you (consults alternates)
+~P message is from you (consults alternates)
+~Q messages which have been replied to
+~R read messages
+~r [MIN]-[MAX] messages with ``date-received'' in a Date range
+~S superseded messages
+~s SUBJECT messages having SUBJECT in the ``Subject'' field.
+~T tagged messages
+~t USER messages addressed to USER
+~U unread messages
+~v message is part of a collapsed thread.
+~V cryptographically verified messages
+~w EXPR messages which contain EXPR in the `Newsgroups' field
+ (if compiled with NNTP support)
+~x EXPR messages which contain EXPR in the `References' field
+~y EXPR messages which contain EXPR in the `X-Label' field
+~z [MIN]-[MAX] messages with a size in the range MIN to MAX *)
+~= duplicated messages (see $duplicate_threads)
+~$ unreferenced messages (requires threaded view)
+~* ``From'' contains realname and (syntactically) valid
+ address (excluded are addresses matching against
+ alternates or any alias)
+
+ Where EXPR, USER, ID, and SUBJECT are regexp. Special attention has to be made when using regular expressions inside of patterns. Specifically, Mutt-ng's parser for these patterns will strip one level of backslash (\), which is normally used for quoting. If it is your intention to use a backslash in the regular expression, you will need to use two backslashes instead (\\).
+
+ *) The forms <[MAX], >[MIN], [MIN]- and -[MAX] are allowed, too.
+
+3. Configuration Commands
+
+ The following are the commands understood by mutt.

- If the _\bc_\bo_\bm_\bm_\ba_\bn_\bd is empty, this operation is disabled for this file type, and the
- file can only be open in the readonly mode.
+ The contrib subdirectory contains a script named update-config.pl which eases migration.
- _\bc_\bl_\bo_\bs_\be_\b-_\bh_\bo_\bo_\bk (section 4.19.2 , page 68) is not called when you exit from the

+1. abort_noattach
- Usage: append-hook _\br_\be_\bg_\be_\bx_\bp '_\bc_\bo_\bm_\bm_\ba_\bn_\bd'
+ Type: quadoption
- This command is used for saving to an existing compressed folder. The _\bc_\bo_\bm_\bm_\ba_\bn_\bd
- is the command that can be used for appending to the folders whose names match
- _\br_\be_\bg_\be_\bx_\bp. It has the same format as in the _\bo_\bp_\be_\bn_\b-_\bh_\bo_\bo_\bk (section 4.19.1 , page 68)
- command. The temporary folder in this case contains the messages that are
- being appended.
+ Default: no
- The _\bc_\bo_\bm_\bm_\ba_\bn_\bd should n\bno\bot\bt remove the decompressed file. The _\bc_\bo_\bm_\bm_\ba_\bn_\bd should return
- non-zero exit status if it fails, so mutt knows something's wrong.
+ This variable specifies whether to abort sending if no attachment was made but the content references them, i.e. the content matches the regular expression given in $attach_remind_regexp. If a match was found and this variable is set to yes, message sending will be aborted but the mail will be send nevertheless if set to no.
- Example:
+ This variable and $attach_remind_regexp are intended to remind the user to attach files if the message's text references them.
- append-hook \\.gz$ "gzip -c %t >> %f"
+ See also the $attach_remind_regexp variable.
- When _\ba_\bp_\bp_\be_\bn_\bd_\b-_\bh_\bo_\bo_\bk (section 4.19.3 , page 69) is used, the folder is not opened,
- which saves time, but this means that we can not find out what the folder type
- is. Thus the default (_\b$_\bm_\bb_\bo_\bx_\b__\bt_\by_\bp_\be (section 7.4.132 , page 121)) type is always
- supposed (i.e. this is the format used for the temporary folder).
+2. abort_nosubject
- If the file does not exist when you save to it, _\bc_\bl_\bo_\bs_\be_\b-_\bh_\bo_\bo_\bk (section 4.19.2 ,
- page 68) is called, and not _\ba_\bp_\bp_\be_\bn_\bd_\b-_\bh_\bo_\bo_\bk (section 4.19.3 , page 69). _\ba_\bp_\bp_\be_\bn_\bd_\b-
- _\bh_\bo_\bo_\bk (section 4.19.3 , page 69) is only for appending to existing folders.
+ Type: quadoption
- If the _\bc_\bo_\bm_\bm_\ba_\bn_\bd is empty, this operation is disabled for this file type. In this
- case, the folder will be open and closed again (using _\bo_\bp_\be_\bn_\b-_\bh_\bo_\bo_\bk (section
- 4.19.1 , page 68) and _\bc_\bl_\bo_\bs_\be_\b-_\bh_\bo_\bo_\bk (section 4.19.2 , page 68)respectively) each
- time you will add to it.
+ Default: ask-yes
- The Mutt Next Generation E-Mail Client 70

+3. abort_unmodified
- The compressed folders support can also be used to handle encrypted folders. If
- you want to encrypt a folder with PGP, you may want to use the following hooks:
+ Type: quadoption
- open-hook \\.pgp$ "pgp -f < %f > %t"
- close-hook \\.pgp$ "pgp -fe YourPgpUserIdOrKeyId < %t > %f"
+ Default: yes
- Please note, that PGP does not support appending to an encrypted folder, so
- there is no append-hook defined.
+ If set to yes, composition will automatically abort after editing the message body if no changes are made to the file (this check only happens after the first edit of the file). When set to no, composition will never be aborted.
- N\bNo\bot\bte\be:\b: the folder is temporary stored decrypted in the /tmp directory, where it
- can be read by your system administrator. So think about the security aspects
- of this.
+4. agent_string
- _\b5_\b. _\bM_\bu_\bt_\bt_\b-_\bn_\bg_\b'_\bs _\bM_\bI_\bM_\bE _\bS_\bu_\bp_\bp_\bo_\br_\bt
+ Type: boolean
- Quite a bit of effort has been made to make Mutt-ng the premier text-mode MIME
- MUA. Every effort has been made to provide the functionality that the discern-
- ing MIME user requires, and the conformance to the standards wherever possible.
- When configuring Mutt-ng for MIME, there are two extra types of configuration
- files which Mutt-ng uses. One is the mime.types file, which contains the map-
- ping of file extensions to IANA MIME types. The other is the mailcap file,
- which specifies the external commands to use for handling specific MIME types.
+ Default: yes
- _\b5_\b._\b1 _\bU_\bs_\bi_\bn_\bg _\bM_\bI_\bM_\bE _\bi_\bn _\bM_\bu_\bt_\bt
+ When set, Mutt-ng will add a ``User-Agent:'' header to outgoing messages, indicating which version of Mutt-ng was used for composing them.
- There are three areas/menus in Mutt-ng which deal with MIME, they are the pager
- (while viewing a message), the attachment menu and the compose menu.
+5. alias_file
- _\b5_\b._\b1_\b._\b1 _\bV_\bi_\be_\bw_\bi_\bn_\bg _\bM_\bI_\bM_\bE _\bm_\be_\bs_\bs_\ba_\bg_\be_\bs _\bi_\bn _\bt_\bh_\be _\bp_\ba_\bg_\be_\br
+ Type: path
- When you select a message from the index and view it in the pager, Mutt decodes
- the message to a text representation. Mutt-ng internally supports a number of
- MIME types, including text/plain, text/enriched, message/rfc822, and mes-
- sage/news. In addition, the export controlled version of Mutt-ng recognizes a
- variety of PGP MIME types, including PGP/MIME and application/pgp.
+ Default: "˜/.muttngrc"
- Mutt-ng will denote attachments with a couple lines describing them. These
- lines are of the form:
+ The default file in which to save aliases created by the ``create-alias'' function.
- [-- Attachment #1: Description --]
- [-- Type: text/plain, Encoding: 7bit, Size: 10000 --]
+ Note: Mutt-ng will not automatically source this file; you must explicitly use the `` source'' command for it to be executed.
- Where the Description is the description or filename given for the attachment,
- and the Encoding is one of 7bit/8bit/quoted-printable/base64/binary.
+6. alias_format
- The Mutt Next Generation E-Mail Client 71
+ Type: string
- If Mutt-ng cannot deal with a MIME type, it will display a message like:
+ Default: "%4n %2f %t %-10a %r"
- [-- image/gif is unsupported (use 'v' to view this part) --]
+ Specifies the format of the data displayed for the ``alias'' menu. The following printf(3)-style sequences are available:
- _\b5_\b._\b1_\b._\b2 _\bT_\bh_\be _\bA_\bt_\bt_\ba_\bc_\bh_\bm_\be_\bn_\bt _\bM_\be_\bn_\bu
+ %a
+ alias name
- The default binding for view-attachments is `v', which displays the attachment

- The compose menu is the menu you see before you send a message. It allows you
- to edit the recipient list, the subject, and other aspects of your message. It
- also contains a list of the attachments of your message, including the main
- body. From this menu, you can print, copy, filter, pipe, edit, compose,
- review, and rename an attachment or a list of tagged attachments. You can also
- modifying the attachment information, notably the type, encoding and descrip-
- tion.
+7. allow_8bit
- Attachments appear as follows:
+ Type: boolean
- - 1 [text/plain, 7bit, 1K] /tmp/mutt-euler-8082-0 <no description>
- 2 [applica/x-gunzip, base64, 422K] ~/src/mutt-0.85.tar.gz <no description>
+ Default: yes
- The '-' denotes that Mutt-ng will delete the file after sending (or postponing,
- or canceling) the message. It can be toggled with the toggle-unlink command
- (default: u). The next field is the MIME content-type, and can be changed with
- the edit-type command (default: ^T). The next field is the encoding for the
- attachment, which allows a binary message to be encoded for transmission on
- 7bit links. It can be changed with the edit-encoding command (default: ^E).
- The next field is the size of the attachment, rounded to kilobytes or
- megabytes. The next field is the filename, which can be changed with the
- rename-file command (default: R). The final field is the description of the
- attachment, and can be changed with the edit-description command (default: d).

+ Default: no
- mime.types file at ${HOME}/.mime.types, and then the system mime.types file at
- /usr/local/share/mutt/mime.types or /etc/mime.types
+ Controls whether ANSI color codes in messages (and color tags in rich text messages) are to be interpreted. Messages containing these codes are rare, but if this option is set, their text will be colored accordingly. Note that this may override your color choices, and even present a security problem, since a message could include a line like ``[-- PGP output follows ..." and give it the same color as your attachment color.
- The mime.types file consist of lines containing a MIME type and a space sepa-
- rated list of extensions. For example:
+9. arrow_cursor
- application/postscript ps eps
- application/pgp pgp
- audio/x-aiff aif aifc aiff
+ Type: boolean
- A sample mime.types file comes with the Mutt-ng distribution, and should con-
- tain most of the MIME types you are likely to use.
+ Default: no
- If Mutt-ng can not determine the mime type by the extension of the file you
- attach, it will look at the file. If the file is free of binary information,
- Mutt-ng will assume that the file is plain text, and mark it as text/plain. If
- the file contains binary information, then Mutt-ng will mark it as applica-
- tion/octet-stream. You can change the MIME type that Mutt-ng assigns to an
- attachment by using the edit-type command from the compose menu (default: ^T).
- The MIME type is actually a major mime type followed by the sub-type, separated
- by a '/'. 6 major types: application, text, image, video, audio, and model have
- been approved after various internet discussions. Mutt-ng recognises all of
- these if the appropriate entry is found in the mime.types file. It also recog-
- nises other major mime types, such as the chemical type that is widely used in
- the molecular modelling community to pass molecular data in various forms to
- various molecular viewers. Non-recognised mime types should only be used if the
- recipient of the message is likely to be expecting such attachments.
+ When set, an arrow (``->'') will be used to indicate the current entry in menus instead of highlighting the whole line. On slow network or modem links this will make response faster because there is less that has to be redrawn on the screen when moving to the next or previous entries in the menu.

+10. ascii_chars
- Mutt-ng supports RFC 1524 MIME Configuration, in particular the Unix specific
- format specified in Appendix A of RFC 1524. This file format is commonly
- referred to as the mailcap format. Many MIME compliant programs utilize the
- mailcap format, allowing you to specify handling for all MIME types in one
- place for all programs. Programs known to use this format include Netscape,
- XMosaic, lynx and metamail.
+ Type: boolean
- In order to handle various MIME types that Mutt-ng can not handle internally,
- Mutt-ng parses a series of external configuration files to find an external
- handler. The default search string for these files is a colon delimited list
- set to
+ Default: no
- ${HOME}/.mailcap:/usr/local/share/mutt/mailcap:/etc/mailcap:/etc/mailcap:/usr/etc/mailcap:/usr/local/etc/mailcap
+ If set, Mutt-ng will use plain ASCII characters when displaying thread and attachment trees, instead of the default ACS characters.
- where $HOME is your home directory.
+11. askbcc
- In particular, the metamail distribution will install a mailcap file, usually
- as /usr/local/etc/mailcap, which contains some baseline entries.
+ Type: boolean
- The Mutt Next Generation E-Mail Client 73
+ Default: no
- _\b5_\b._\b3_\b._\b1 _\bT_\bh_\be _\bB_\ba_\bs_\bi_\bc_\bs _\bo_\bf _\bt_\bh_\be _\bm_\ba_\bi_\bl_\bc_\ba_\bp _\bf_\bi_\bl_\be
+ If set, Mutt-ng will prompt you for blind-carbon-copy (Bcc) recipients before editing an outgoing message.
- A mailcap file consists of a series of lines which are comments, blank, or def-
- initions.
+12. askcc
- A comment line consists of a # character followed by anything you want.
+ Type: boolean
- A blank line is blank.
+ Default: no
- A definition line consists of a content type, a view command, and any number of
- optional fields. Each field of a definition line is divided by a semicolon ';'
- character.
+ If set, Mutt-ng will prompt you for carbon-copy (Cc) recipients before editing the body of an outgoing message.
- The content type is specified in the MIME standard type/subtype method. For
- example, text/plain, text/html, image/gif, etc. In addition, the mailcap for-
- mat includes two formats for wildcards, one using the special '*' subtype, the
- other is the implicit wild, where you only include the major type. For exam-
- ple, image/*, or video, will match all image types and video types, respec-
- tively.
+13. assumed_charset
- The view command is a Unix command for viewing the type specified. There are
- two different types of commands supported. The default is to send the body of
- the MIME message to the command on stdin. You can change this behavior by using
- %s as a parameter to your view command. This will cause Mutt-ng to save the
- body of the MIME message to a temporary file, and then call the view command
- with the %s replaced by the name of the temporary file. In both cases, Mutt-ng
- will turn over the terminal to the view program until the program quits, at
- which time Mutt will remove the temporary file if it exists.
+ Type: string
- So, in the simplest form, you can send a text/plain message to the external
- pager more on stdin:
+ Default: "us-ascii"
- text/plain; more
+ This variable is a colon-separated list of character encoding schemes for messages without character encoding indication. Header field values and message body content without character encoding indication would be assumed that they are written in one of this list. By default, all the header fields and message body without any charset indication are assumed to be in us-ascii.
- Or, you could send the message as a file:
+ For example, Japanese users might prefer this:
- text/plain; more %s
+ set assumed_charset="iso-2022-jp:euc-jp:shift_jis:utf-8"
- Perhaps you would like to use lynx to interactively view a text/html message:
+ However, only the first content is valid for the message body. This variable is valid only if $strict_mime is unset.
- text/html; lynx %s
+14. attach_format
- In this case, lynx does not support viewing a file from stdin, so you must use
- the %s syntax. N\bNo\bot\bte\be:\b: _\bS_\bo_\bm_\be _\bo_\bl_\bd_\be_\br _\bv_\be_\br_\bs_\bi_\bo_\bn_\bs _\bo_\bf _\bl_\by_\bn_\bx _\bc_\bo_\bn_\bt_\ba_\bi_\bn _\ba _\bb_\bu_\bg _\bw_\bh_\be_\br_\be _\bt_\bh_\be_\by _\bw_\bi_\bl_\bl

- _\bw_\bh_\bi_\bc_\bh _\bc_\ba_\bl_\bl_\bs _\bl_\by_\bn_\bx_\b, _\ba_\bn_\bd _\br_\bu_\bn _\bi_\bt_\b. _\bT_\bh_\bi_\bs _\bc_\ba_\bu_\bs_\be_\bs _\bl_\by_\bn_\bx _\bt_\bo _\bc_\bo_\bn_\bt_\bi_\bn_\bu_\bo_\bu_\bs_\bl_\by _\bs_\bp_\ba_\bw_\bn _\bi_\bt_\bs_\be_\bl_\bf _\bt_\bo
- _\bv_\bi_\be_\bw _\bt_\bh_\be _\bo_\bb_\bj_\be_\bc_\bt_\b.
+ Type: string
- On the other hand, maybe you don't want to use lynx interactively, you just
- want to have it convert the text/html to text/plain, then you can use:
+ Default: "%u%D%I %t%4n %T%.40d%> [%.7m/%.10M, %.6e%?C?, %C?, %s] "
- The Mutt Next Generation E-Mail Client 74
+ This variable describes the format of the ``attachment'' menu. The following printf(3)-style sequences are understood:
- text/html; lynx -dump %s | more
+ %C
+ charset
- Perhaps you wish to use lynx to view text/html files, and a pager on all other
- text formats, then you would use the following:
+ %c
+ requires charset conversion (n or c)
- text/html; lynx %s
- text/*; more
+ %D
+ deleted flag
- This is the simplest form of a mailcap file.

+ %e
+ MIME Content-Transfer-Encoding: header field
- The interpretation of shell meta-characters embedded in MIME parameters can
- lead to security problems in general. Mutt-ng tries to quote parameters in
- expansion of %s syntaxes properly, and avoids risky characters by substituting
- them, see the _\bm_\ba_\bi_\bl_\bc_\ba_\bp_\b__\bs_\ba_\bn_\bi_\bt_\bi_\bz_\be (section 7.4.123 , page 119) variable.
+ %f
+ filename
- Although mutt's procedures to invoke programs with mailcap seem to be safe,
- there are other applications parsing mailcap, maybe taking less care of it.
- Therefore you should pay attention to the following rules:
+ %I
+ MIME Content-Disposition: header field (I=inline, A=attachment)
- _\bK_\be_\be_\bp _\bt_\bh_\be _\b%_\b-_\be_\bx_\bp_\ba_\bn_\bd_\bo_\bs _\ba_\bw_\ba_\by _\bf_\br_\bo_\bm _\bs_\bh_\be_\bl_\bl _\bq_\bu_\bo_\bt_\bi_\bn_\bg_\b. Don't quote them with single or
- double quotes. Mutt-ng does this for you, the right way, as should any other
- program which interprets mailcap. Don't put them into backtick expansions. Be
- highly careful with eval statements, and avoid them if possible at all. Trying
- to fix broken behaviour with quotes introduces new leaks - there is no alterna-
- tive to correct quoting in the first place.
+ %m
+ major MIME type
- If you have to use the %-expandos' values in context where you need quoting or
- backtick expansions, put that value into a shell variable and reference the
- shell variable where necessary, as in the following example (using $charset
- inside the backtick expansion is safe, since it is not itself subject to any
- further expansion):
+ %M
+ MIME subtype
- text/test-mailcap-bug; cat %s; copiousoutput; test=charset=%{charset} \

+ %t
+ tagged flag
- In addition to the required content-type and view command fields, you can add
- semi-colon ';' separated fields to set flags and other options. Mutt-ng recog-
- nizes the following optional fields:
+ %T
+ graphic tree characters
- copiousoutput
- This flag tells Mutt-ng that the command passes possibly large
- amounts of text on stdout. This causes Mutt-ng to invoke a pager
- (either the internal pager or the external pager defined by the
- pager variable) on the output of the view command. Without this
+ %u
+ unlink (=to delete) flag
- The Mutt Next Generation E-Mail Client 75
-
- flag, Mutt-ng assumes that the command is interactive. One could
- use this to replace the pipe to more in the lynx -dump example in
- the Basic section:
-
- text/html; lynx -dump %s ; copiousoutput
-
- This will cause lynx to format the text/html output as text/plain
- and Mutt-ng will use your standard pager to display the results.
+ %>X
+ right justify the rest of the string and pad with character "X"
- needsterminal
- Mutt-ng uses this flag when viewing attachments with _\ba_\bu_\bt_\bo_\bv_\bi_\be_\bw (sec-
- tion 5.4 , page 78), in order to decide whether it should honor
- the setting of the _\b$_\bw_\ba_\bi_\bt_\b__\bk_\be_\by (section 7.4.341 , page 172) variable
- or not. When an attachment is viewed using an interactive program,
- and the corresponding mailcap entry has a _\bn_\be_\be_\bd_\bs_\bt_\be_\br_\bm_\bi_\bn_\ba_\bl flag, Mutt-
- ng will use _\b$_\bw_\ba_\bi_\bt_\b__\bk_\be_\by (section 7.4.341 , page 172) and the exit
- status of the program to decide if it will ask you to press a key
- after the external program has exited. In all other situations it
- will not prompt you for a key.
+ %|X
+ pad to the end of the line with character "X"
- compose=<command>
- This flag specifies the command to use to create a new attachment
- of a specific MIME type. Mutt-ng supports this from the compose
- menu.
+15. attach_remind_regexp
- composetyped=<command>
- This flag specifies the command to use to create a new attachment
- of a specific MIME type. This command differs from the compose
- command in that mutt will expect standard MIME headers on the data.
- This can be used to specify parameters, filename, description, etc.
- for a new attachment. Mutt-ng supports this from the compose
- menu.
-
- print=<command>
- This flag specifies the command to use to print a specific MIME
- type. Mutt-ng supports this from the attachment and compose menus.
-
- edit=<command>
- This flag specifies the command to use to edit a specific MIME
- type. Mutt-ng supports this from the compose menu, and also uses
- it to compose new attachments. Mutt-ng will default to the defined
- editor for text attachments.
-
- nametemplate=<template>
- This field specifies the format for the file denoted by %s in the
- command fields. Certain programs will require a certain file
- extension, for instance, to correctly view a file. For instance,
- lynx will only interpret a file as text/html if the file ends in
- .html. So, you would specify lynx as a text/html viewer with a
- line in the mailcap file like:
-
- text/html; lynx %s; nametemplate=%s.html
-
- The Mutt Next Generation E-Mail Client 76
-
- test=<command>
- This field specifies a command to run to test whether this mailcap
- entry should be used. The command is defined with the command
- expansion rules defined in the next section. If the command
- returns 0, then the test passed, and Mutt-ng uses this entry. If
- the command returns non-zero, then the test failed, and Mutt-ng
- continues searching for the right entry. N\bNo\bot\bte\be:\b: _\bt_\bh_\be _\bc_\bo_\bn_\bt_\be_\bn_\bt_\b-_\bt_\by_\bp_\be
- _\bm_\bu_\bs_\bt _\bm_\ba_\bt_\bc_\bh _\bb_\be_\bf_\bo_\br_\be _\bM_\bu_\bt_\bt_\b-_\bn_\bg _\bp_\be_\br_\bf_\bo_\br_\bm_\bs _\bt_\bh_\be _\bt_\be_\bs_\bt_\b. For example:
-
- text/html; netscape -remote 'openURL(%s)' ; test=RunningX
- text/html; lynx %s
-
- In this example, Mutt-ng will run the program RunningX which will
- return 0 if the X Window manager is running, and non-zero if it
- isn't. If RunningX returns 0, then Mutt-ng will call netscape to
- display the text/html object. If RunningX doesn't return 0, then
- Mutt-ng will go on to the next entry and use lynx to display the
- text/html object.
+ Type: regular expression
- _\b5_\b._\b3_\b._\b3_\b._\b2 _\bS_\be_\ba_\br_\bc_\bh _\bO_\br_\bd_\be_\br
+ Default: "attach"
- When searching for an entry in the mailcap file, Mutt-ng will search for the
- most useful entry for its purpose. For instance, if you are attempting to
- print an image/gif, and you have the following entries in your mailcap file,
- Mutt-ng will search for an entry with the print command:
+ If this variable is non-empty, muttng will scan a message's contents before sending for this regular expression. If it is found, it will ask for what to do depending on the setting of $abort_noattach.
- image/*; xv %s
- image/gif; ; print= anytopnm %s | pnmtops | lpr; \
- nametemplate=%s.gif
+ This variable and $abort_noattach are intended to remind the user to attach files if the message's text references them.
- Mutt-ng will skip the image/* entry and use the image/gif entry with the print
- command.
+16. attach_sep
- In addition, you can use this with _\bA_\bu_\bt_\bo_\bv_\bi_\be_\bw (section 5.4 , page 78) to denote
- two commands for viewing an attachment, one to be viewed automatically, the
- other to be viewed interactively from the attachment menu. In addition, you
- can then use the test feature to determine which viewer to use interactively
- depending on your environment.
-
- text/html; netscape -remote 'openURL(%s)' ; test=RunningX
- text/html; lynx %s; nametemplate=%s.html
- text/html; lynx -dump %s; nametemplate=%s.html; copiousoutput
+ Type: string
- For _\bA_\bu_\bt_\bo_\bv_\bi_\be_\bw (section 5.4 , page 78), Mutt-ng will choose the third entry
- because of the copiousoutput tag. For interactive viewing, Mutt will run the
- program RunningX to determine if it should use the first entry. If the program
- returns non-zero, Mutt-ng will use the second entry for interactive viewing.
+ Default: "\n"

- it is parsed to expand various special parameters with information from Mutt-
- ng. The keywords Mutt-ng expands are:
+17. attach_split
- %s
- As seen in the basic mailcap section, this variable is expanded to
- a filename specified by the calling program. This file contains
- the body of the message to view/print/edit or where the composing
- program should place the results of composition. In addition, the
- use of this keyword causes Mutt-ng to not pass the body of the mes-
- sage to the view/print/edit program on stdin.
+ Type: boolean
- %t
- Mutt-ng will expand %t to the text representation of the content
- type of the message in the same form as the first parameter of the
- mailcap definition line, ie text/html or image/gif.
+ Default: yes
- %{<parameter>}
- Mutt-ng will expand this to the value of the specified parameter
- from the Content-Type: line of the mail message. For instance, if
- Your mail message contains:
+ If this variable is unset, when operating (saving, printing, piping, etc) on a list of tagged attachments, Mutt-ng will concatenate the attachments and will operate on them as a single attachment. The ``$attach_sep'' separator is added after each attachment. When set, Mutt-ng will operate on the attachments one by one.
- Content-Type: text/plain; charset=iso-8859-1
+18. attribution
- then Mutt-ng will expand %{charset} to iso-8859-1. The default
- metamail mailcap file uses this feature to test the charset to
- spawn an xterm using the right charset to view the message.
+ Type: string
- \%
- This will be replaced by a %
+ Default: "On %d, %n wrote:"
- Mutt-ng does not currently support the %F and %n keywords specified in RFC
- 1524. The main purpose of these parameters is for multipart messages, which is
- handled internally by Mutt-ng.

- This mailcap file is fairly simple and standard:
+ Type: boolean
- # I'm always running X :)
- video/*; xanim %s > /dev/null
- image/*; xv %s > /dev/null
+ Default: no
- # I'm always running netscape (if my computer had more memory, maybe)
- text/html; netscape -remote 'openURL(%s)'
+ When set, functions in the index menu which affect a message will be applied to all tagged messages (if there are any). When unset, you must first use the ``tag-prefix'' function (default: ";") to make the next function apply to all tagged messages.
- This mailcap file shows quite a number of examples:
+20. autoedit
- The Mutt Next Generation E-Mail Client 78
+ Type: boolean
- # Use xanim to view all videos Xanim produces a header on startup,
- # send that to /dev/null so I don't see it

+ Default: no
- # Send html to a running netscape by remote
- text/html; netscape -remote 'openURL(%s)'; test=RunningNetscape
+ When set along with ``$edit_headers'', Mutt-ng will skip the initial send-menu and allow you to immediately begin editing the body of your message. The send-menu may still be accessed once you have finished editing the body of your message.
- # If I'm not running netscape but I am running X, start netscape on the
- # object

+ When this variable is set, Mutt-ng will beep whenever it prints a message notifying you of new mail. This is independent of the setting of the ``$beep'' variable.
- In addition to explicitly telling Mutt-ng to view an attachment with the MIME
- viewer defined in the mailcap file, Mutt-ng has support for automatically view-
- ing MIME attachments while in the pager.
+23. bounce
- To work, you must define a viewer in the mailcap file which uses the copi-
- ousoutput option to denote that it is non-interactive. Usually, you also use
- the entry to convert the attachment to a text representation which you can view
- in the pager.
+ Type: quadoption
- You then use the auto_view muttrc command to list the content-types that you
- wish to view automatically.
+ Default: ask-yes
- For instance, if you set auto_view to:
+ Controls whether you will be asked to confirm bouncing messages. If set to yes you don't get asked if you want to bounce a message. Setting this variable to no is not generally useful, and thus not recommended, because you are unable to bounce messages.

+ Type: boolean
- Mutt-ng has some heuristics for determining which attachment of a multi-
- part/alternative type to display. First, mutt will check the alternative_order
- list to determine if one of the available types is preferred. The alterna-
- tive_order list consists of a number of MIME types in order, including support
- for implicit and explicit wildcards, for example:
+ Default: no
- alternative_order text/enriched text/plain text application/postscript image/*
+ When this variable is set, mutt will place the cursor at the beginning of the current line in menus, even when the arrow_cursor variable is unset, making it easier for blind persons using Braille displays to follow these menus. The option is disabled by default because many visual terminals don't permit making the cursor invisible.
- Next, mutt will check if any of the types have a defined _\ba_\bu_\bt_\bo_\b__\bv_\bi_\be_\bw (section
- 5.4 , page 78), and use that. Failing that, Mutt-ng will look for any text
- type. As a last attempt, mutt will look for any type it knows how to handle.
+26. certificate_file
- To remove a MIME type from the alternative_order list, use the unalterna-

+ Type: path
- _\b5_\b._\b6 _\bM_\bI_\bM_\bE _\bL_\bo_\bo_\bk_\bu_\bp
+ Default: "˜/.mutt_certificates"
- Mutt-ng's mime_lookup list specifies a list of mime-types that should not be
- treated according to their mailcap entry. This option is designed to deal with
- binary types such as application/octet-stream. When an attachment's mime-type
- is listed in mime_lookup, then the extension of the filename will be compared
- to the list of extensions in the mime.types file. The mime-type associated
- with this extension will then be used to process the attachment according to
- the rules in the mailcap file and according to any other configuration options
- (such as auto_view) specified. Common usage would be:
+ Availability: SSL or GNUTLS
- mime_lookup application/octet-stream application/X-Lotus-Manuscript
+ This variable specifies the file where the certificates you trust are saved. When an unknown certificate is encountered, you are asked if you accept it or not. If you accept it, the certificate can also be saved in this file and further connections are automatically accepted.
- In addition, the unmime_lookup command may be used to disable this feature for
+ You can also manually add CA certificates in this file. Any server certificate that is signed with one of these CA certificates are also automatically accepted.

- When configuring mutt-ng, there're some points to note about secure setups.
+28. check_new
- In practice, mutt-ng can be easily made as vulnerable as even the most insecure
- mail user agents (in their default configuration) just by changing mutt-ng's
- configuration files: it then can execute arbitrary programs and scripts
- attached to messages, send out private data on its own, etc. Although this is
- not believed to the common type of setup, please read this chapter carefully.
+ Type: boolean
- _\b6_\b._\b1 _\bP_\ba_\bs_\bs_\bw_\bo_\br_\bd_\bs
+ Default: yes
- Although mutt-ng can be told the various passwords for accounts, please never
- store passwords in configuration files. Besides the fact that the system's
- operator can always read them, you could forget to replace the actual password
- with asterisks when reporting a bug or asking for help via, for example, a
- mailing list so that your mail including your password could be archived by
- internet search engines, etc. Please never store passwords on disk.
+ Note: this option only affects maildir and MH style mailboxes.
- _\b6_\b._\b2 _\bT_\be_\bm_\bp_\bo_\br_\ba_\br_\by _\bF_\bi_\bl_\be_\bs
+ When set, Mutt-ng will check for new mail delivered while the mailbox is open. Especially with MH mailboxes, this operation can take quite some time since it involves scanning the directory and checking each file to see if it has already been looked at. If it's unset, no check for new mail is performed while the mailbox is open.
- Mutt-ng uses many temporary files for viewing messages, verifying digital sig-
- natures, etc. The _\b$_\bu_\bm_\ba_\bs_\bk (section 7.4.333 , page 170) variable can be used to
- change the default permissions of these files. Please only change it if you
- really know what you are doing. Also, a different location for these files may
- be desired which can be changed via the _\b$_\bt_\bm_\bp_\bd_\bi_\br (section 7.4.329 , page 169)

+ Default: yes
- In the default configuration, mutt-ng will leak some information to the outside
- world when sending messages: the generation of Message-ID: headers includes a
- step counter which is increased (and rotated) with every message sent. If you'd
- like to hide this information probably telling others how many mail you sent in

- of the _\b$_\bm_\bs_\bg_\bi_\bd_\b__\bf_\bo_\br_\bm_\ba_\bt (section 7.4.149 , page 124) variable. Please make sure

- As mutt-ng be can be set up to be the mail client to handle mailto: style links
- in websites, there're security considerations, too. To keep the old behavior by
- default, mutt-ng will be strict in interpreting them which means that arbitrary
- header fields can be embedded in these links which could override existing
- header fields or attach arbitrary files. This may be problematic if the
- _\b$_\be_\bd_\bi_\bt_\b__\bh_\be_\ba_\bd_\be_\br_\bs (section 7.4.59 , page 102) variable is _\bu_\bn_\bs_\be_\bt, i.e. the user

- this option is set, their text will be colored accordingly. Note that this may
- override your color choices, and even present a security problem, since a mes-
- sage could include a line like ``[-- PGP output follows ...' and give it the
- same color as your attachment color.
+ This option allows you to edit the header of your outgoing messages along with the body of your message.
- _\b7_\b._\b4_\b._\b9 _\ba_\br_\br_\bo_\bw_\b__\bc_\bu_\br_\bs_\bo_\br
+ Which empty header fields to show is controlled by the $editor_headers option.

+60. editor
- Default: no
+ Type: path
- When _\bs_\be_\bt, an arrow (``->'') will be used to indicate the current entry in menus
- instead of highlighting the whole line. On slow network or modem links this
- will make response faster because there is less that has to be redrawn on the
- screen when moving to the next or previous entries in the menu.
+ Default: ""

- If _\bs_\be_\bt, Mutt-ng will use plain ASCII characters when displaying thread and
- attachment trees, instead of the default ACS characters.
+ If $edit_headers is set, this space-separated list specifies which non-empty header fields to edit in addition to user-defined headers.
- _\b7_\b._\b4_\b._\b1_\b1 _\ba_\bs_\bk_\bb_\bc_\bc
+ Note: if $edit_headers had to be turned on by force because $strict_mailto is unset, this option has no effect.
- Type: boolean
+62. encode_from
- Default: no
+ Type: boolean
- If _\bs_\be_\bt, Mutt-ng will prompt you for blind-carbon-copy (Bcc) recipients before
- editing an outgoing message.
+ Default: no
- _\b7_\b._\b4_\b._\b1_\b2 _\ba_\bs_\bk_\bc_\bc
+ When set, Mutt-ng will quoted-printable encode messages when they contain the string ``From '' (note the trailing space) in the beginning of a line. Useful to avoid the tampering certain mail delivery and transport agents tend to do with messages.
- Type: boolean
+ Note: as mutt-ng currently violates RfC3676 defining format=flowed, it's <em/strongly/ advised to set this option although discouraged by the standard. Alternatively, you must take care of space-stuffing <tt/From / lines (with a trailing space) yourself.
- Default: no
+63. entropy_file
- If _\bs_\be_\bt, Mutt-ng will prompt you for carbon-copy (Cc) recipients before editing
- the body of an outgoing message.
+ Type: path

- Type: string
+ Availability: SSL
- Default: 'us-ascii'
+ The file which includes random data that is used to initialize SSL library functions.
- This variable is a colon-separated list of character encoding schemes for mes-
- sages without character encoding indication. Header field values and message
- body content without character encoding indication would be assumed that they
- are written in one of this list. By default, all the header fields and message
- body without any charset indication are assumed to be in us-ascii.
+64. envelope_from
- For example, Japanese users might prefer this:
+ Type: boolean
- set assumed_charset='iso-2022-jp:euc-jp:shift_jis:utf-8'
+ Default: no
- However, only the first content is valid for the message body. This variable
- is valid only if _\b$_\bs_\bt_\br_\bi_\bc_\bt_\b__\bm_\bi_\bm_\be (section 7.4.318 , page 167) is unset.
+ When set, Mutt-ng will try to derive the message's envelope sender from the ``From:'' header field. Note that this information is passed to the sendmail command using the ``-f" command line switch, so don't set this option if you are using that switch in $sendmail yourself, or if the sendmail on your machine doesn't support that command line switch.

- %M
- MIME subtype
+68. fcc_clear
- %n
- attachment number
+ Type: boolean
- %s
- size
+ Default: no
- %t
- tagged flag
+ When this variable is set, FCCs will be stored unencrypted and unsigned, even when the actual message is encrypted and/or signed. (PGP only)
- %T
- graphic tree characters
+69. file_charset
- %u
- unlink (=to delete) flag
+ Type: string

- right justify the rest of the string and pad with character 'X'
+ Default: ""
- %|X
- pad to the end of the line with character 'X'
+ This variable is a colon-separated list of character encoding schemes for text file attatchments. If unset, $charset value will be used instead. For example, the following configuration would work for Japanese text handling:
- _\b7_\b._\b4_\b._\b1_\b5 _\ba_\bt_\bt_\ba_\bc_\bh_\b__\br_\be_\bm_\bi_\bn_\bd_\b__\br_\be_\bg_\be_\bx_\bp

- Type: regular expression
+ Note: ``iso-2022-*'' must be put at the head of the value as shown above if included.
- Default: 'attach'
+70. folder
- The Mutt Next Generation E-Mail Client 93
+ Type: path
- If this variable is non-empty, muttng will scan a message's contents before
- sending for this regular expression. If it is found, it will ask for what to do
- depending on the setting of _\b$_\ba_\bb_\bo_\br_\bt_\b__\bn_\bo_\ba_\bt_\bt_\ba_\bc_\bh (section 7.4.1 , page 88).
+ Default: "˜/Mail"
- This variable and _\b$_\ba_\bb_\bo_\br_\bt_\b__\bn_\bo_\ba_\bt_\bt_\ba_\bc_\bh (section 7.4.1 , page 88) are intended to
- remind the user to attach files if the message's text references them.
+ Specifies the default location of your mailboxes. A ``+'' or ``='' at the beginning of a pathname will be expanded to the value of this variable. Note that if you change this variable from the default value you need to make sure that the assignment occurs before you use ``+'' or ``='' for any other variables since expansion takes place during the ``set'' command.

- The separator to add between attachments when operating (saving, printing, pip-
- ing, etc) on a list of tagged attachments.
+ This variable allows you to customize the file browser display to your personal taste. This string is similar to ``$index_format'', but has its own set of printf(3)-like sequences:
- _\b7_\b._\b4_\b._\b1_\b7 _\ba_\bt_\bt_\ba_\bc_\bh_\b__\bs_\bp_\bl_\bi_\bt
+ %C
+ current file number
- Type: boolean
+ %d
+ date/time folder was last modified
- Default: yes
+ %f
+ filename
- If this variable is _\bu_\bn_\bs_\be_\bt, when operating (saving, printing, piping, etc) on a
- list of tagged attachments, Mutt-ng will concatenate the attachments and will
- operate on them as a single attachment. The ``_\b$_\ba_\bt_\bt_\ba_\bc_\bh_\b__\bs_\be_\bp (section 7.4.16 ,
- page 93)'' separator is added after each attachment. When _\bs_\be_\bt, Mutt-ng will
- operate on the attachments one by one.

- Type: string
+ %l
+ number of hard links
- Default: 'On %d, %n wrote:'
+ %N
+ N if folder has new mail, blank otherwise
- This is the string that will precede a message which has been included in a

- Type: boolean
+ Type: boolean
- Default: no
+ Default: yes
- The Mutt Next Generation E-Mail Client 94
+ Controls whether or not the Mail-Followup-To: header field is generated when sending mail. When set, Mutt-ng will generate this field when you are replying to a known mailing list, specified with the ``subscribe'' or ``lists'' commands or detected by common mailing list headers.
- When _\bs_\be_\bt along with ``_\b$_\be_\bd_\bi_\bt_\b__\bh_\be_\ba_\bd_\be_\br_\bs (section 7.4.59 , page 102)'', Mutt-ng
- will skip the initial send-menu and allow you to immediately begin editing the
- body of your message. The send-menu may still be accessed once you have fin-
- ished editing the body of your message.
+ This field has two purposes. First, preventing you from receiving duplicate copies of replies to messages which you send to mailing lists. Second, ensuring that you do get a reply separately for any messages sent to known lists to which you are not subscribed. The header will contain only the list's address for subscribed lists, and both the list address and your own email address for unsubscribed lists. Without this header, a group reply to your message sent to a subscribed list will be sent to both the list and your address, resulting in two copies of the same email for you.

+ Default: no
- When this variable is _\bs_\be_\bt, Mutt-ng will beep whenever it prints a message noti-
- fying you of new mail. This is independent of the setting of the ``_\b$_\bb_\be_\be_\bp (sec-
- tion 7.4.21 , page 94)'' variable.
+ This variable is similar to ``$save_name'', except that Mutt-ng will store a copy of your outgoing message by the username of the address you are sending to even if that mailbox does not exist.

+ Type: boolean
- Controls whether you will be asked to confirm bouncing messages. If set to _\by_\be_\bs
- you don't get asked if you want to bounce a message. Setting this variable to
- _\bn_\bo is not generally useful, and thus not recommended, because you are unable to

- Type: boolean
+76. forward_decrypt
- Default: yes
+ Type: boolean
- When this variable is _\bs_\be_\bt, Mutt-ng will include Delivered-To: header fields
- when bouncing messages. Postfix users may wish to _\bu_\bn_\bs_\be_\bt this variable.
+ Default: yes
- _\b7_\b._\b4_\b._\b2_\b5 _\bb_\br_\ba_\bi_\bl_\bl_\be_\b__\bf_\br_\bi_\be_\bn_\bd_\bl_\by

- Type: boolean
+77. forward_edit

- Default: '~/.mutt_certificates'
+ This variable controls the default subject when forwarding a message. It uses the same format sequences as the ``$index_format'' variable.
- Availability: SSL or GNUTLS
+79. forward_quote
- This variable specifies the file where the certificates you trust are saved.
- When an unknown certificate is encountered, you are asked if you accept it or
- not. If you accept it, the certificate can also be saved in this file and fur-
- ther connections are automatically accepted.
+ Type: boolean
- You can also manually add CA certificates in this file. Any server certificate
- that is signed with one of these CA certificates are also automatically
- accepted.
+ Default: no
- Example: set certificate_file=~/.muttng/certificates
+ When set forwarded messages included in the main body of the message (when ``$mime_forward'' is unset) will be quoted using ``$indent_string''.

+80. from
- Type: string
+ Type: e-mail address
- Default: ''
+ Default: ""
- Character set your terminal uses to display and enter textual data.
+ This variable contains a default from address. It can be overridden using my_hdr (including from send-hooks) and ``$reverse_name''. This variable is ignored if ``$use_from'' is unset.
- _\b7_\b._\b4_\b._\b2_\b8 _\bc_\bh_\be_\bc_\bk_\b__\bn_\be_\bw
+ E.g. you can use send-hook Mutt-ng-devel@lists.berlios.de 'my_hdr From: Foo Bar <foo@bar.fb>' when replying to the mutt-ng developer's mailing list and Mutt-ng takes this email address.
- Type: boolean
+ Defaults to the contents of the environment variable $EMAIL.
- Default: yes
+81. gecos_mask
- N\bNo\bot\bte\be:\b: this option only affects _\bm_\ba_\bi_\bl_\bd_\bi_\br and _\bM_\bH style mailboxes.
+ Type: regular expression
- When _\bs_\be_\bt, Mutt-ng will check for new mail delivered while the mailbox is open.
- Especially with MH mailboxes, this operation can take quite some time since it
- involves scanning the directory and checking each file to see if it has already
- been looked at. If it's _\bu_\bn_\bs_\be_\bt, no check for new mail is performed while the
- mailbox is open.
+ Default: "^[^,]*"
- _\b7_\b._\b4_\b._\b2_\b9 _\bc_\bo_\bl_\bl_\ba_\bp_\bs_\be_\b__\bu_\bn_\br_\be_\ba_\bd
+ A regular expression used by Mutt-ng to parse the GECOS field of a password entry when expanding the alias. By default the regular expression is set to ``^[^,]*'' which will return the string up to the first ``,'' encountered. If the GECOS field contains a string like "lastname, firstname" then you should do: set gecos_mask=".*".
- Type: boolean
+ This can be useful if you see the following behavior: you address a e-mail to user ID stevef whose full name is Steve Franklin. If Mutt-ng expands stevef to ``Franklin'' stevef@foo.bar then you should set the gecos_mask to a regular expression that will match the whole name so Mutt-ng will expand ``Franklin'' to ``Franklin, Steve''.
- Default: yes
+82. hdrs
- When _\bu_\bn_\bs_\be_\bt, Mutt-ng will not collapse a thread if it contains any unread mes-
- sages.

+ Default: yes
- _\b7_\b._\b4_\b._\b3_\b0 _\bc_\bo_\bm_\bp_\bo_\bs_\be_\b__\bf_\bo_\br_\bm_\ba_\bt
+ When unset, the header fields normally added by the ``my_hdr'' command are not created. This variable must be unset before composing a new message or replying in order to take effect. If set, the user defined header fields are added to every new message.
- Type: string
+83. header
- Default: '-- Mutt-ng: Compose [Approx. msg size: %l Atts: %a]%>-'
+ Type: boolean
- Controls the format of the status line displayed in the ``compose'' menu. This
- string is similar to ``_\b$_\bs_\bt_\ba_\bt_\bu_\bs_\b__\bf_\bo_\br_\bm_\ba_\bt (section 7.4.315 , page 164)'', but has
- its own set of printf(3)-like sequences:
+ Default: no
- %a
- total number of attachments
+ When set, this variable causes Mutt-ng to include the header of the message you are replying to into the edit buffer. The ``$weed'' setting applies.
- %h
- local hostname
+84. header_cache
- %l
- approximate size (in bytes) of the current message
+ Type: path

+ Availability: Header Cache
- _\b7_\b._\b4_\b._\b3_\b1 _\bc_\bo_\bn_\bf_\bi_\bg_\b__\bc_\bh_\ba_\br_\bs_\be_\bt
+ The $header_cache variable points to the header cache database.
- Type: string
+ If $header_cache points to a directory it will contain a header cache database per folder. If $header_cache points to a file that file will be a single global header cache. By default it is unset so no header caching will be used.
- Default: ''
+85. header_cache_compress
- When defined, Mutt-ng will recode commands in rc files from this encoding.
+ Type: boolean
- _\b7_\b._\b4_\b._\b3_\b2 _\bc_\bo_\bn_\bf_\bi_\br_\bm_\ba_\bp_\bp_\be_\bn_\bd
+ Default: no
- Type: boolean
+ If enabled the header cache will be compressed. So only one fifth of the usual diskspace is used, but the uncompression can result in a slower open of the cached folder.
- Default: yes
+86. help
- When _\bs_\be_\bt, Mutt-ng will prompt for confirmation when appending messages to an
- existing mailbox.
+ Type: boolean
- _\b7_\b._\b4_\b._\b3_\b3 _\bc_\bo_\bn_\bf_\bi_\br_\bm_\bc_\br_\be_\ba_\bt_\be
+ Default: yes
- Type: boolean
+ When set, help lines describing the bindings for the major functions provided by each menu are displayed on the first line of the screen.
- Default: yes
+ Note: The binding will not be displayed correctly if the function is bound to a sequence rather than a single keystroke. Also, the help line may not be updated if a binding is changed while Mutt-ng is running. Since this variable is primarily aimed at new users, neither of these should present a major problem.
- When _\bs_\be_\bt, Mutt-ng will prompt for confirmation when saving messages to a mail-
- box which does not yet exist before creating it.

- The Mutt Next Generation E-Mail Client 97
+ Default: no
- Type: number
+ When set, Mutt-ng will skip the host name part of ``$hostname'' variable when adding the domain part to addresses. This variable does not affect the generation of Message-ID: header fields, and it will not lead to the cut-off of first-level domains.
- Default: 30
+88. hide_limited
- Causes Mutt-ng to timeout a network connection (for IMAP or POP) after this
- many seconds if the connection is not able to be established. A negative value
- causes Mutt-ng to wait indefinitely for the connection to succeed.
+ Type: boolean
- _\b7_\b._\b4_\b._\b3_\b5 _\bc_\bo_\bn_\bt_\be_\bn_\bt_\b__\bt_\by_\bp_\be
+ Default: no
- Type: string
+ When set, Mutt-ng will not show the presence of messages that are hidden by limiting, in the thread tree.

- Type: boolean
+ When set, Mutt-ng will not show the subject of messages in the thread tree that have the same subject as their parent or closest previously displayed sibling.
- Default: no
+91. hide_top_limited
- Setting this variable will cause Mutt-ng to always attempt to PGP encrypt out-
- going messages. This is probably only useful in connection to the _\bs_\be_\bn_\bd_\b-_\bh_\bo_\bo_\bk
- command. It can be overridden by use of the _\bp_\bg_\bp_\b-_\bm_\be_\bn_\bu, when encryption is not

+ Affects the behaviour of the reply function when replying to messages from mailing lists. When set, if the ``Reply-To:'' header field is set to the same value as the ``To:'' header field, Mutt-ng assumes that the ``Reply-To:'' header field was set by the mailing list to automate responses to the list, and will ignore this field. To direct a response to the mailing list when this option is set, use the list-reply function; group-reply will reply to both the sender and the list.

- Default: yes
+ Note: Mutt-ng will only fall back to other authentication methods if the previous methods are unavailable. If a method is available but authentication fails, Mutt-ng will not connect to the IMAP server.
- If _\bs_\be_\bt, Mutt-ng will include a time stamp in the lines surrounding PGP or

- Default: '~f %s !~P | (~P ~C %s)'
+ This variable specifies the maximum amount of time in seconds that Mutt-ng will wait before polling open IMAP connections, to prevent the server from closing them before Mutt-ng has finished with them.
- This variable controls how send-hooks, message-hooks, save-hooks, and fcc-hooks
- will be interpreted if they are specified with only a simple regexp, instead of
- a matching pattern. The hooks are expanded when they are declared, so a hook
- will be interpreted according to the value of this variable at the time the
- hook is declared. The default value matches if the message is either from a
- user matching the regular expression given, or if it is from you (if the from
- address matches ``alternates'') and is to or cc'ed to a user matching the given
- regular expression.
+ The default is well within the RFC-specified minimum amount of time (30 minutes) before a server is allowed to do this, but in practice the RFC does get violated every now and then.

+ Default: "C"
- This field has two purposes. First, preventing you from receiving duplicate
- copies of replies to messages which you send to mailing lists. Second, ensuring
- that you do get a reply separately for any messages sent to known lists to
- which you are not subscribed. The header will contain only the list's address
- for subscribed lists, and both the list address and your own email address for
- unsubscribed lists. Without this header, a group reply to your message sent to
- a subscribed list will be sent to both the list and your address, resulting in

- This quadoption controls whether or not the user is automatically placed in the
- editor when forwarding messages. For those who always want to forward with no
- modification, use a setting of _\bn_\bo.
+ NOTE: this only applies to maildir-style mailboxes. Setting it will have no effect on other mailbox types.
- _\b7_\b._\b4_\b._\b7_\b8 _\bf_\bo_\br_\bw_\ba_\br_\bd_\b__\bf_\bo_\br_\bm_\ba_\bt
+ It is similiar to the trash option.
- Type: string
+126. mark_old
- Default: '[%a: %s]'
+ Type: boolean
- This variable controls the default subject when forwarding a message. It uses
- the same format sequences as the ``_\b$_\bi_\bn_\bd_\be_\bx_\b__\bf_\bo_\br_\bm_\ba_\bt (section 7.4.116 , page
- 115)'' variable.
+ Default: yes
- _\b7_\b._\b4_\b._\b7_\b9 _\bf_\bo_\br_\bw_\ba_\br_\bd_\b__\bq_\bu_\bo_\bt_\be
+ Controls whether or not Mutt-ng marks new unread messages as old if you exit a mailbox without reading them.
- Type: boolean
+ With this option set, the next time you start Mutt-ng, the messages will show up with an "O" next to them in the ``index'' menu, indicating that they are old.
- Default: no
+127. markers
- When _\bs_\be_\bt forwarded messages included in the main body of the message (when
- ``_\b$_\bm_\bi_\bm_\be_\b__\bf_\bo_\br_\bw_\ba_\br_\bd (section 7.4.143 , page 123)'' is _\bu_\bn_\bs_\be_\bt) will be quoted using
- ``_\b$_\bi_\bn_\bd_\be_\bn_\bt_\b__\bs_\bt_\br_\bi_\bn_\bg (section 7.4.115 , page 115)''.
+ Type: boolean
- _\b7_\b._\b4_\b._\b8_\b0 _\bf_\br_\bo_\bm
+ Default: yes
- Type: e-mail address
+ Controls the display of wrapped lines in the internal pager. If set, a ``+'' marker is displayed at the beginning of wrapped lines. Also see the ``$smart_wrap'' variable.
- Default: ''
+128. mask
- This variable contains a default from address. It can be overridden using
- my_hdr (including from send-hooks) and ``_\b$_\br_\be_\bv_\be_\br_\bs_\be_\b__\bn_\ba_\bm_\be (section 7.4.243 , page
- 147)''. This variable is ignored if ``_\b$_\bu_\bs_\be_\b__\bf_\br_\bo_\bm (section 7.4.337 , page
- 171)'' is unset.
+ Type: regular expression
- The Mutt Next Generation E-Mail Client 108
+ Default: "!^\.[^.]"
- E.g. you can use send-hook Mutt-ng-devel@lists.berlios.de 'my_hdr From: Foo Bar
- <foo@bar.fb>' when replying to the mutt-ng developer's mailing list and Mutt-ng
- takes this email address.
+ A regular expression used in the file browser, optionally preceded by the not operator ``!''. Only files whose names match this mask will be shown. The match is always case-sensitive.
- Defaults to the contents of the environment variable $EMAIL.
+129. max_display_recips
- _\b7_\b._\b4_\b._\b8_\b1 _\bg_\be_\bc_\bo_\bs_\b__\bm_\ba_\bs_\bk
+ Type: number
- Type: regular expression
+ Default: 0
- Default: '^[^,]*'
+ When set non-zero, this specifies the maximum number of recipient header lines (To:, Cc: and Bcc:) to display in the pager if header weeding is turned on. In case the number of lines exeeds its value, the last line will have 3 dots appended.
- A regular expression used by Mutt-ng to parse the GECOS field of a password
- entry when expanding the alias. By default the regular expression is set to
- ``^[^,]*'' which will return the string up to the first ``,'' encountered. If
- the GECOS field contains a string like 'lastname, firstname' then you should
- do: set gecos_mask='.*'.
+130. max_line_length
- This can be useful if you see the following behavior: you address a e-mail to
- user ID stevef whose full name is Steve Franklin. If Mutt-ng expands stevef to
- ``Franklin'' stevef@foo.bar then you should set the gecos_mask to a regular
- expression that will match the whole name so Mutt-ng will expand ``Franklin''
- to ``Franklin, Steve''.
+ Type: number
- _\b7_\b._\b4_\b._\b8_\b2 _\bh_\bd_\br_\bs
+ Default: 0
- Type: boolean
+ When set, the maximum line length for displaying ``format = flowed'' messages is limited to this length. A value of 0 (which is also the default) means that the maximum line length is determined by the terminal width and $wrapmargin.
- Default: yes
+131. mbox
- When _\bu_\bn_\bs_\be_\bt, the header fields normally added by the ``_\bm_\by_\b__\bh_\bd_\br (section 3.16 ,
- page 37)'' command are not created. This variable _\bm_\bu_\bs_\bt be _\bu_\bn_\bs_\be_\bt before compos-
- ing a new message or replying in order to take effect. If _\bs_\be_\bt, the user
- defined header fields are added to every new message.
+ Type: path
- _\b7_\b._\b4_\b._\b8_\b3 _\bh_\be_\ba_\bd_\be_\br
+ Default: "˜/mbox"
- Type: boolean
+ This specifies the folder into which read mail in your ``$spoolfile'' folder will be appended.
- Default: no
+132. mbox_type
- When _\bs_\be_\bt, this variable causes Mutt-ng to include the header of the message you
- are replying to into the edit buffer. The ``_\b$_\bw_\be_\be_\bd (section 7.4.342 , page
- 172)'' setting applies.
+ Type: folder magic
- _\b7_\b._\b4_\b._\b8_\b4 _\bh_\be_\ba_\bd_\be_\br_\b__\bc_\ba_\bc_\bh_\be
+ Default: mbox
- Type: path
+ The default mailbox type used when creating new folders. May be any of mbox, MMDF, MH and Maildir.

- The Mutt Next Generation E-Mail Client 109
+ This variable controls the number of lines of context that are given when scrolling through menus. (Similar to ``$pager_context''.)
- cache database.
+134. menu_move_off
- If _\b$_\bh_\be_\ba_\bd_\be_\br_\b__\bc_\ba_\bc_\bh_\be (section 7.4.84 , page 108) points to a directory it will
- contain a header cache database per folder. If _\b$_\bh_\be_\ba_\bd_\be_\br_\b__\bc_\ba_\bc_\bh_\be (section
- 7.4.84 , page 108) points to a file that file will be a single global header
- cache. By default it is _\bu_\bn_\bs_\be_\bt so no header caching will be used.
+ Type: boolean
- _\b7_\b._\b4_\b._\b8_\b5 _\bh_\be_\ba_\bd_\be_\br_\b__\bc_\ba_\bc_\bh_\be_\b__\bc_\bo_\bm_\bp_\br_\be_\bs_\bs
+ Default: yes
- Type: boolean
+ When unset, the bottom entry of menus will never scroll up past the bottom of the screen, unless there are less entries than lines. When set, the bottom entry may move off the bottom.
- Default: no
+135. menu_scroll
- If enabled the header cache will be compressed. So only one fifth of the usual
- diskspace is used, but the uncompression can result in a slower open of the
- cached folder.
+ Type: boolean
- _\b7_\b._\b4_\b._\b8_\b6 _\bh_\be_\bl_\bp
+ Default: no
- Type: boolean
+ When set, menus will be scrolled up or down one line when you attempt to move across a screen boundary. If unset, the screen is cleared and the next or previous page of the menu is displayed (useful for slow links to avoid many redraws).
- Default: yes
+136. message_format
- When _\bs_\be_\bt, help lines describing the bindings for the major functions provided
- by each menu are displayed on the first line of the screen.
+ Type: string
- N\bNo\bot\bte\be:\b: The binding will not be displayed correctly if the function is bound to a
- sequence rather than a single keystroke. Also, the help line may not be
- updated if a binding is changed while Mutt-ng is running. Since this variable
- is primarily aimed at new users, neither of these should present a major prob-
- lem.
+ Default: "%s"
- _\b7_\b._\b4_\b._\b8_\b7 _\bh_\bi_\bd_\bd_\be_\bn_\b__\bh_\bo_\bs_\bt
+ This is the string displayed in the ``attachment'' menu for attachments of type message/rfc822. For a full listing of defined printf(3)-like sequences see the section on ``$index_format''.
- Type: boolean
+137. meta_key
- Default: no
+ Type: boolean
- When _\bs_\be_\bt, Mutt-ng will skip the host name part of ``_\b$_\bh_\bo_\bs_\bt_\bn_\ba_\bm_\be (section
- 7.4.95 , page 110)'' variable when adding the domain part to addresses. This
- variable does not affect the generation of Message-ID: header fields, and it
- will not lead to the cut-off of first-level domains.
+ Default: no
- _\b7_\b._\b4_\b._\b8_\b8 _\bh_\bi_\bd_\be_\b__\bl_\bi_\bm_\bi_\bt_\be_\bd
+ If set, forces Mutt-ng to interpret keystrokes with the high bit (bit 8) set as if the user had pressed the ESC key and whatever key remains after having the high bit removed. For example, if the key pressed has an ASCII value of 0xf4, then this is treated as if the user had pressed ESC then ``x''. This is because the result of removing the high bit from ``0xf4'' is ``0x74'', which is the ASCII character ``x''.
- Type: boolean
+138. metoo
- Default: no
+ Type: boolean
- When _\bs_\be_\bt, Mutt-ng will not show the presence of messages that are hidden by
- limiting, in the thread tree.
+ Default: no
- _\b7_\b._\b4_\b._\b8_\b9 _\bh_\bi_\bd_\be_\b__\bm_\bi_\bs_\bs_\bi_\bn_\bg
+ If unset, Mutt-ng will remove your address (see the ``alternates'' command) from the list of recipients when replying to a message.
- The Mutt Next Generation E-Mail Client 110
+139. mh_purge
- Type: boolean
+ Type: boolean
- Default: yes
+ Default: no
- When _\bs_\be_\bt, Mutt-ng will not show the presence of missing messages in the thread
- tree.
+ When unset, Mutt-ng will mimic mh's behaviour and rename deleted messages to ,<old file name> in mh folders instead of really deleting them. If the variable is set, the message files will simply be deleted.

+ Type: string
- Default: no
+ Default: "replied"
- When _\bs_\be_\bt, Mutt-ng will not show the presence of messages that are hidden by
- limiting, at the top of threads in the thread tree. Note that when _\b$_\bh_\bi_\bd_\be_\b__\bm_\bi_\bs_\bs_\b-

+142. mh_seq_unseen
- Type: boolean
+ Type: string
- Default: yes
+ Default: "unseen"
- When _\bs_\be_\bt, Mutt-ng will not show the presence of missing messages at the top of
- threads in the thread tree. Note that when _\b$_\bh_\bi_\bd_\be_\b__\bl_\bi_\bm_\bi_\bt_\be_\bd (section 7.4.88 ,
- page 109) is _\bs_\be_\bt, this option will have no effect.
+ The name of the MH sequence used for unseen messages.

+143. mime_forward
- Type: number
+ Type: quadoption
- Default: 10
+ Default: no
- This variable controls the size (in number of strings remembered) of the string
- history buffer. The buffer is cleared each time the variable is changed.
+ When set, the message you are forwarding will be attached as a separate MIME part instead of included in the main body of the message.
- _\b7_\b._\b4_\b._\b9_\b4 _\bh_\bo_\bn_\bo_\br_\b__\bf_\bo_\bl_\bl_\bo_\bw_\bu_\bp_\b__\bt_\bo
+ This is useful for forwarding MIME messages so the receiver can properly view the message as it was delivered to you. If you like to switch between MIME and not MIME from mail to mail, set this variable to ask-no or ask-yes.
- Type: quadoption
+ Also see ``$forward_decode'' and ``$mime_forward_decode''.
- Default: yes
+144. mime_forward_decode
- This variable controls whether or not a Mail-Followup-To: header field is hon-
- ored when group-replying to a message.
+ Type: boolean
- The Mutt Next Generation E-Mail Client 111
+ Default: no
- _\b7_\b._\b4_\b._\b9_\b5 _\bh_\bo_\bs_\bt_\bn_\ba_\bm_\be
+ Controls the decoding of complex MIME messages into text/plain when forwarding a message while ``$mime_forward'' is set. Otherwise ``$forward_decode'' is used instead.
- Type: string
+145. mime_forward_rest
- Default: ''
+ Type: quadoption
- Specifies the hostname to use after the ``@'' in local e-mail addresses and
- during generation of Message-Id: headers.
+ Default: yes
- Please be sure to really know what you are doing when changing this variable to
- configure a custom domain part of Message-IDs.

- Type: boolean
+ Type: string
- Default: no
+ Default: "%4n %c %-16s %a"
- Affects the behaviour of the _\br_\be_\bp_\bl_\by function when replying to messages from
- mailing lists. When _\bs_\be_\bt, if the ``Reply-To:'' header field is set to the same
- value as the ``To:'' header field, Mutt-ng assumes that the ``Reply-To:''
- header field was set by the mailing list to automate responses to the list, and
- will ignore this field. To direct a response to the mailing list when this
- option is set, use the _\bl_\bi_\bs_\bt_\b-_\br_\be_\bp_\bl_\by function; _\bg_\br_\bo_\bu_\bp_\b-_\br_\be_\bp_\bl_\by will reply to both the
- sender and the list.

- tication methods are either ``login'' or the right side of an IMAP ``AUTH=''
- capability string, e.g. ``digest-md5'', ``gssapi'' or ``cram-md5''. This param-
- eter is case-insensitive.
+ %a

+ Default: no
- Default: yes
+ Availability: NNTP
- Availability: IMAP
+ If set, Mutt-ng will prompt you for the Followup-To: header field before editing the body of an outgoing news article.
- When _\bs_\be_\bt, Mutt-ng will display warning messages from the IMAP server as error
- messages. Since these messages are often harmless, or generated due to configu-
- ration problems on the server which are out of the users' hands, you may wish
- to suppress them at some point.

- Type: boolean
+ This variable points to directory where Mutt-ng will cache news article headers. If unset, headers will not be saved at all and will be reloaded each time when you enter a newsgroup.
- Default: no
+ As for the header caching in connection with IMAP and/or Maildir, this drastically increases speed and lowers traffic.
- If _\bs_\be_\bt, Mutt-ng will look for a mailcap entry with the ``copiousoutput'' flag
- set for _\be_\bv_\be_\br_\by MIME attachment it doesn't have an internal viewer defined for.

- Default: yes
+183. pager_context
- Controls the display of wrapped lines in the internal pager. If set, a ``+''

- case the number of lines exeeds its value, the last line will have 3 dots
- appended.
+ Determines the number of lines of a mini-index which is shown when in the pager. The current message, unless near the top or bottom of the folder, will be roughly one third of the way down this mini-index, giving the reader the context of a few messages before and after the message. This is useful, for example, to determine how many messages remain to be read in the current thread. One of the lines is reserved for the status bar from the index, so a pager_index_lines of 6 will only show 5 lines of the actual index. A value of 0 results in no index being shown. If the number of messages in the current folder is less than pager_index_lines, then the index will only use as many lines as it needs.

+ If set, Mutt-ng will automatically attempt to decrypt traditional PGP messages whenever the user performs an operation which ordinarily would result in the contents of the message being operated on. For example, if the user displays a pgp-traditional message which has not been manually checked with the check-traditional-pgp function, Mutt-ng will automatically check the message for traditional pgp.

- If _\bs_\be_\bt, forces Mutt-ng to interpret keystrokes with the high bit (bit 8) set as
- if the user had pressed the ESC key and whatever key remains after having the
- high bit removed. For example, if the key pressed has an ASCII value of 0xf4,
- then this is treated as if the user had pressed ESC then ``x''. This is
- because the result of removing the high bit from ``0xf4'' is ``0x74'', which is
- the ASCII character ``x''.

+230. postponed
- Type: boolean
+ Type: path
- Default: no
+ Default: "˜/postponed"
- Availability: NNTP
+ Mutt-ng allows you to indefinitely ``postpone sending a message'' which you are editing. When you choose to postpone a message, Mutt-ng saves it in the mailbox specified by this variable. Also see the ``$postpone'' variable.
- If _\bs_\be_\bt, only subscribed newsgroups that contain unread articles will be dis-
- played in the newsgroup browser.
+231. preconnect
- _\b7_\b._\b4_\b._\b1_\b7_\b0 _\bn_\bn_\bt_\bp_\b__\bu_\bs_\be_\br
+ Type: string
- Type: string
+ Default: ""
- Default: ''
+ If set, a shell command to be executed if Mutt-ng fails to establish a connection to the server. This is useful for setting up secure connections, e.g. with ssh(1). If the command returns a nonzero status, Mutt-ng gives up opening the server. Example:
- Availability: NNTP
+ preconnect="ssh -f -q -L 1234:mailhost.net:143 mailhost.net sleep 20 < /dev/null > /dev/null"
- Your login name on the NNTP server. If _\bu_\bn_\bs_\be_\bt and the server requires authen-
- tification, Mutt-ng will prompt you for your account name.
+ Mailbox ``foo'' on mailhost.net can now be reached as ``{localhost:1234}foo''.
- _\b7_\b._\b4_\b._\b1_\b7_\b1 _\bn_\bn_\bt_\bp_\b__\bx_\b__\bc_\bo_\bm_\bm_\be_\bn_\bt_\b__\bt_\bo
+ Note: For this example to work, you must be able to log in to the remote machine without having to enter a password.
- Type: boolean
+232. print
- Default: no
+ Type: quadoption
- Availability: NNTP
+ Default: ask-no
- If _\bs_\be_\bt, Mutt-ng will add a ``X-Comment-To:'' header field (that contains full
- name of the original article author) to articles that you followup to.
+ Controls whether or not Mutt-ng really prints messages. This is set to ask-no by default, because some people accidentally hit ``p'' often.

+233. print_command
- Type: string
+ Type: path
- Default: ''
+ Default: "lpr"
- This specifies the operating system name for the User-Agent: header field. If
- this is _\bu_\bn_\bs_\be_\bt, it will be set to the operating system name that uname(2)
- returns. If uname(2) fails, ``UNIX'' will be used.
+ This specifies the command pipe that should be used to print messages.
- It may, for example, look as: ``mutt-ng 1.5.9i (Linux)''.
+234. print_decode
- _\b7_\b._\b4_\b._\b1_\b7_\b3 _\bp_\ba_\bg_\be_\br
+ Type: boolean
- Type: path
+ Default: yes
- Default: 'builtin'
+ Used in connection with the print-message command. If this option is set, the message is decoded before it is passed to the external command specified by $print_command. If this option is unset, no processing will be applied to the message when printing it. The latter setting may be useful if you are using some advanced printer filter which is able to properly format e-mail messages for printing.
- The Mutt Next Generation E-Mail Client 132
+235. print_split
- This variable specifies which pager you would like to use to view messages.
- ``builtin'' means to use the builtin pager, otherwise this variable should
- specify the pathname of the external pager you would like to use.
+ Type: boolean
- Using an external pager may have some disadvantages: Additional keystrokes are
- necessary because you can't call Mutt-ng functions directly from the pager, and
- screen resizes cause lines longer than the screen width to be badly formatted
- in the help menu.
+ Default: no
- _\b7_\b._\b4_\b._\b1_\b7_\b4 _\bp_\ba_\bg_\be_\br_\b__\bc_\bo_\bn_\bt_\be_\bx_\bt
+ Used in connection with the print-message command. If this option is set, the command specified by $print_command is executed once for each message which is to be printed. If this option is unset, the command specified by $print_command is executed only once, and all the messages are concatenated, with a form feed as the message separator.
- Type: number
+ Those who use the enscript(1) program's mail-printing mode will most likely want to set this option.
- Default: 0
+236. prompt_after
- This variable controls the number of lines of context that are given when dis-
- playing the next or previous page in the internal pager. By default, Mutt-ng
- will display the line after the last one on the screen at the top of the next
- page (0 lines of context).
+ Type: boolean
- _\b7_\b._\b4_\b._\b1_\b7_\b5 _\bp_\ba_\bg_\be_\br_\b__\bf_\bo_\br_\bm_\ba_\bt
+ Default: yes
- Type: string
+ If you use an external ``$pager'', setting this variable will cause Mutt-ng to prompt you for a command when the pager exits rather than returning to the index menu. If unset, Mutt-ng will return to the index menu when the external pager exits.
- Default: '-%Z- %C/%m: %-20.20n %s'
+237. query_command
- This variable controls the format of the one-line message ``status'' displayed
- before each message in either the internal or an external pager. The valid
- sequences are listed in the ``_\b$_\bi_\bn_\bd_\be_\bx_\b__\bf_\bo_\br_\bm_\ba_\bt (section 7.4.116 , page 115)''
- section.
+ Type: path
- _\b7_\b._\b4_\b._\b1_\b7_\b6 _\bp_\ba_\bg_\be_\br_\b__\bi_\bn_\bd_\be_\bx_\b__\bl_\bi_\bn_\be_\bs
+ Default: ""
- Type: number
+ This specifies the command that Mutt-ng will use to make external address queries. The string should contain a %s, which will be substituted with the query string the user types. See ``query'' for more information.
- Default: 0
+238. quit
- Determines the number of lines of a mini-index which is shown when in the
- pager. The current message, unless near the top or bottom of the folder, will
- be roughly one third of the way down this mini-index, giving the reader the
- context of a few messages before and after the message. This is useful, for
- example, to determine how many messages remain to be read in the current
- thread. One of the lines is reserved for the status bar from the index, so a
- _\bp_\ba_\bg_\be_\br_\b__\bi_\bn_\bd_\be_\bx_\b__\bl_\bi_\bn_\be_\bs of 6 will only show 5 lines of the actual index. A value of
- 0 results in no index being shown. If the number of messages in the current
- folder is less than _\bp_\ba_\bg_\be_\br_\b__\bi_\bn_\bd_\be_\bx_\b__\bl_\bi_\bn_\be_\bs, then the index will only use as many
- lines as it needs.
+ Type: quadoption
- _\b7_\b._\b4_\b._\b1_\b7_\b7 _\bp_\ba_\bg_\be_\br_\b__\bs_\bt_\bo_\bp
+ Default: yes
- Type: boolean
+ This variable controls whether ``quit'' and ``exit'' actually quit from Mutt-ng. If it set to yes, they do quit, if it is set to no, they have no effect, and if it is set to ask-yes or ask-no, you are prompted for confirmation when you try to quit.
- Default: no
+239. quote_empty
- The Mutt Next Generation E-Mail Client 133
+ Type: boolean
- When _\bs_\be_\bt, the internal-pager will n\bno\bot\bt move to the next message when you are at
- the end of a message and invoke the _\bn_\be_\bx_\bt_\b-_\bp_\ba_\bg_\be function.
+ Default: yes
- _\b7_\b._\b4_\b._\b1_\b7_\b8 _\bp_\bg_\bp_\b__\ba_\bu_\bt_\bo_\b__\bd_\be_\bc_\bo_\bd_\be
+ Controls whether or not empty lines will be quoted using ``indent_string''.
- Type: boolean
+240. quote_quoted
- Default: no
+ Type: boolean
- If _\bs_\be_\bt, Mutt-ng will automatically attempt to decrypt traditional PGP messages
- whenever the user performs an operation which ordinarily would result in the
- contents of the message being operated on. For example, if the user displays a
- pgp-traditional message which has not been manually checked with the check-tra-
- ditional-pgp function, Mutt-ng will automatically check the message for tradi-
- tional pgp.
+ Default: no
- _\b7_\b._\b4_\b._\b1_\b7_\b9 _\bp_\bg_\bp_\b__\ba_\bu_\bt_\bo_\bi_\bn_\bl_\bi_\bn_\be
+ Controls how quoted lines will be quoted. If set, one quote character will be added to the end of existing prefix. Otherwise, quoted lines will be prepended by ``indent_string''.
- Type: boolean
+241. quote_regexp
- Default: no
+ Type: regular expression
- This option controls whether Mutt-ng generates old-style inline (traditional)
- PGP encrypted or signed messages under certain circumstances. This can be
- overridden by use of the _\bp_\bg_\bp_\b-_\bm_\be_\bn_\bu, when inline is not required.
+ Default: "^([ \t]*[|>:}#])+"
- Note that Mutt-ng might automatically use PGP/MIME for messages which consist
- of more than a single MIME part. Mutt-ng can be configured to ask before send-
- ing PGP/MIME messages when inline (traditional) would not work. See also:
- ``_\b$_\bp_\bg_\bp_\b__\bm_\bi_\bm_\be_\b__\ba_\bu_\bt_\bo (section 7.4.195 , page 137)''.
+ A regular expression used in the internal-pager to determine quoted sections of text in the body of a message.
- Also note that using the old-style PGP message format is s\bst\btr\bro\bon\bng\bgl\bly\by d\bde\bep\bpr\bre\bec\bca\bat\bte\bed\bd.
- (PGP only)
+ Note: In order to use the quotedx patterns in the internal pager, you need to set this to a regular expression that matches exactly the quote characters at the beginning of quoted lines.

+242. read_inc
- Type: boolean
+ Type: number
- Default: yes
+ Default: 10
- If _\bs_\be_\bt, Mutt-ng will check the exit code of the PGP subprocess when signing or
- encrypting. A non-zero exit code means that the subprocess failed. (PGP only)
+ If set to a value greater than 0, Mutt-ng will display which message it is currently on when reading a mailbox. The message is printed after read_inc messages have been read (e.g., if set to 25, Mutt-ng will print a message when it reads message 25, and then again when it gets to message 50). This variable is meant to indicate progress when reading large mailboxes which may take some time. When set to 0, only a single message will appear before the reading the mailbox.
- _\b7_\b._\b4_\b._\b1_\b8_\b1 _\bp_\bg_\bp_\b__\bc_\bl_\be_\ba_\br_\bs_\bi_\bg_\bn_\b__\bc_\bo_\bm_\bm_\ba_\bn_\bd
+ Also see the ``$write_inc'' variable.
- Type: string
+243. read_only
- Default: ''
+ Type: boolean
- This format is used to create a old-style ``clearsigned'' PGP message.
+ Default: no
- Note that the use of this format is s\bst\btr\bro\bon\bng\bgl\bly\by d\bde\bep\bpr\bre\bec\bca\bat\bte\bed\bd. (PGP only)
+ If set, all folders are opened in read-only mode.

+ Type: string
- Type: string
+ Default: ""
- Default: ''
+ This variable specifies what ``real'' or ``personal'' name should be used when sending messages.
- This format strings specifies a command which is used to decode application/pgp
- attachments.
+ By default, this is the GECOS field from /etc/passwd.
- The PGP command formats have their own set of printf(3)-like sequences:
+ Note: This variable will not be used when the user has set a real name in the $from variable.
- %p
- Expands to PGPPASSFD=0 when a pass phrase is needed, to an empty
- string otherwise. Note: This may be used with a %? construct.
+245. recall
- %f
- Expands to the name of a file containing a message.
+ Type: quadoption
- %s
- Expands to the name of a file containing the signature part of a
- multipart/signed attachment when verifying it.
+ Default: ask-yes
- %a
- The value of _\b$_\bp_\bg_\bp_\b__\bs_\bi_\bg_\bn_\b__\ba_\bs (section 7.4.199 , page 138).
+ Controls whether or not Mutt-ng recalls postponed messages when composing a new message. Also see ``$postponed''.
- %r
- One or more key IDs.
+ Setting this variable to yes is not generally useful, and thus not recommended.
- For examples on how to configure these formats for the various versions of PGP
- which are floating around, see the pgp*.rc and gpg.rc files in the samples/
- subdirectory which has been installed on your system alongside the documenta-

+ Type: path
- Type: string
+ Default: ""
- Default: ''
+ This specifies the file into which your outgoing messages should be appended. (This is meant as the primary method for saving a copy of your messages, but another way to do this is using the ``my_hdr'' command to create a Bcc: header field with your email address in it.)
- This command is used to decrypt a PGP encrypted message. (PGP only)
+ The value of $record is overridden by the ``$force_name'' and ``$save_name'' variables, and the ``fcc-hook'' command.

+ Type: regular expression
- Default: ''
+ Default: "^(re([\[0-9\]+])*|aw):[ \t]*"
- This command is used to encrypt a body part without signing it. (PGP only)

+248. reply_self
- Type: string
+ Type: boolean
- Default: ''
+ Default: no
- The Mutt Next Generation E-Mail Client 135
+ If unset and you are replying to a message sent by you, Mutt-ng will assume that you want to reply to the recipients of that message rather than to yourself.
- This command is used to both sign and encrypt a body part. (PGP only)
+249. reply_to
- _\b7_\b._\b4_\b._\b1_\b8_\b6 _\bp_\bg_\bp_\b__\be_\bn_\bt_\br_\by_\b__\bf_\bo_\br_\bm_\ba_\bt
+ Type: quadoption
- Type: string
+ Default: ask-yes
- Default: '%4n %t%f %4l/0x%k %-4a %2c %u'
+ If set, when replying to a message, Mutt-ng will use the address listed in the ``Reply-To:'' header field as the recipient of the reply. If unset, it will use the address in the ``From:'' header field instead.
- This variable allows you to customize the PGP key selection menu to your per-
- sonal taste. This string is similar to ``_\b$_\bi_\bn_\bd_\be_\bx_\b__\bf_\bo_\br_\bm_\ba_\bt (section 7.4.116 , page
- 115)'', but has its own set of printf(3)-like sequences:
+ This option is useful for reading a mailing list that sets the ``Reply-To:'' header field to the list address and you want to send a private message to the author of a message.
- %n
- number
+250. resolve
- %k
- key id
+ Type: boolean
- %u
- user id
+ Default: yes

- %l
- key length
+251. reverse_alias
- %f
- flags
+ Type: boolean
- %c
- capabilities
+ Default: no
- %t
- trust/validity of the key-uid association
+ This variable controls whether or not Mutt-ng will display the ``personal'' name from your aliases in the index menu if it finds an alias that matches the message's sender. For example, if you have the following alias:
- %[<s>]
- date of the key where <s> is an strftime(3) expression
+ alias juser abd30425@somewhere.net (Joe User)
- (PGP only)
+ and then you receive mail which contains the following header:
- _\b7_\b._\b4_\b._\b1_\b8_\b7 _\bp_\bg_\bp_\b__\be_\bx_\bp_\bo_\br_\bt_\b__\bc_\bo_\bm_\bm_\ba_\bn_\bd
+ From: abd30425@somewhere.net
- Type: string
+ It would be displayed in the index menu as ``Joe User'' instead of ``abd30425@somewhere.net.'' This is useful when the person's e-mail address is not human friendly (like CompuServe addresses).
- Default: ''
+252. reverse_name
- This command is used to export a public key from the user's key ring. (PGP
- only)
+ Type: boolean
- _\b7_\b._\b4_\b._\b1_\b8_\b8 _\bp_\bg_\bp_\b__\bg_\be_\bt_\bk_\be_\by_\bs_\b__\bc_\bo_\bm_\bm_\ba_\bn_\bd
+ Default: no
- Type: string
+ It may sometimes arrive that you receive mail to a certain machine, move the messages to another machine, and reply to some the messages from there. If this variable is set, the default From: line of the reply messages is built using the address where you received the messages you are replying to if that address matches your alternates. If the variable is unset, or the address that would be used doesn't match your alternates, the From: line will use your address on the current machine.
- The Mutt Next Generation E-Mail Client 136
+253. reverse_realname
- Default: ''
+ Type: boolean
- This command is invoked whenever Mutt-ng will need public key information. %r
- is the only printf(3)-like sequence used with this format. (PGP only)
+ Default: yes
- _\b7_\b._\b4_\b._\b1_\b8_\b9 _\bp_\bg_\bp_\b__\bg_\bo_\bo_\bd_\b__\bs_\bi_\bg_\bn
+ This variable fine-tunes the behaviour of the reverse_name feature. When it is set, Mutt-ng will use the address from incoming messages as-is, possibly including eventual real names. When it is unset, Mutt-ng will override any such real names with the setting of the realname variable.
- Type: regular expression
+254. rfc2047_parameters
- Default: ''
+ Type: boolean
- If you assign a text to this variable, then a PGP signature is only considered
- verified if the output from _\b$_\bp_\bg_\bp_\b__\bv_\be_\br_\bi_\bf_\by_\b__\bc_\bo_\bm_\bm_\ba_\bn_\bd (section 7.4.205 , page 139)
- contains the text. Use this variable if the exit code from the command is 0

- _\b7_\b._\b4_\b._\b1_\b9_\b0 _\bp_\bg_\bp_\b__\bi_\bg_\bn_\bo_\br_\be_\b__\bs_\bu_\bb_\bk_\be_\by_\bs
+ When this variable is set, Mutt-ng will decode RFC-2047-encoded MIME parameters. You want to set this variable when Mutt-ng suggests you to save attachments to files named like this:
- Type: boolean
+ =?iso-8859-1?Q?file=5F=E4=5F991116=2Ezip?=
- Default: yes
+ When this variable is set interactively, the change doesn't have the desired effect before you have changed folders.
- Setting this variable will cause Mutt-ng to ignore OpenPGP subkeys. Instead,
- the principal key will inherit the subkeys' capabilities. _\bU_\bn_\bs_\be_\bt this if you
- want to play interesting key selection games. (PGP only)
+ Note that this use of RFC 2047's encoding is explicitly, prohibited by the standard, but nevertheless encountered in the wild.
- _\b7_\b._\b4_\b._\b1_\b9_\b1 _\bp_\bg_\bp_\b__\bi_\bm_\bp_\bo_\br_\bt_\b__\bc_\bo_\bm_\bm_\ba_\bn_\bd
+ Also note that setting this parameter will not have the effect that Mutt-ng generates this kind of encoding. Instead, Mutt-ng will unconditionally use the encoding specified in RFC 2231.
- Type: string

- The Mutt Next Generation E-Mail Client 137
+ This variable controls how copies of outgoing messages are saved. When set, a check is made to see if a mailbox specified by the recipient address exists (this is done by searching for a mailbox in the ``$folder'' directory with the username part of the recipient address). If the mailbox exists, the outgoing message will be saved to that mailbox, otherwise the message is saved to the ``$record'' mailbox.

- Type: boolean
+268. sidebar_newmail_only
- Default: yes
+ Type: boolean
- If _\bs_\be_\bt, Mutt-ng will automatically encode PGP/MIME signed messages as quoted-

+ When set, the ``hierarchy'' of the sidebar entries will be shortened only if they cannot be printed in full length (because ``$sidebar_width'' is set to a too low value). For example, if the newsgroup name ``de.alt.sysadmin.recovery'' doesn't fit on the screen, it'll get shortened ``d.a.s.recovery'' while ``de.alt.d0'' still would and thus will not get shortened.
- Type: boolean
+ At which characters this compression is done is controled via the $sidebar_boundary variable.
- The Mutt Next Generation E-Mail Client 140
+271. sidebar_visible
- Default: no
+ Type: boolean
- Used in connection with the _\bp_\bi_\bp_\be_\b-_\bm_\be_\bs_\bs_\ba_\bg_\be command. When _\bu_\bn_\bs_\be_\bt, Mutt-ng will
- pipe the messages without any preprocessing. When _\bs_\be_\bt, Mutt-ng will weed head-
- ers and will attempt to PGP/MIME decode the messages first.
+ Default: no

- Used in connection with the _\bp_\bi_\bp_\be_\b-_\bm_\be_\bs_\bs_\ba_\bg_\be command and the ``tag- prefix'' or
- ``tag-prefix-cond'' operators. If this variable is _\bu_\bn_\bs_\be_\bt, when piping a list
- of tagged messages Mutt-ng will concatenate the messages and will pipe them as
- a single folder. When _\bs_\be_\bt, Mutt-ng will pipe the messages one by one. In both
- cases the messages are piped in the current sorted order, and the ``_\b$_\bp_\bi_\bp_\be_\b__\bs_\be_\bp
- (section 7.4.208 , page 139)'' separator is added after each message.
+ Default: yes
- _\b7_\b._\b4_\b._\b2_\b1_\b0 _\bp_\bo_\bp_\b__\ba_\bu_\bt_\bh_\b__\bt_\br_\by_\b__\ba_\bl_\bl
+ If set, a line containing ``-- '' (dash, dash, space) will be inserted before your ``$signature''. It is strongly recommended that you not unset this variable unless your ``signature'' contains just your name. The reason for this is because many software packages use ``-- \n'' to detect your signature.
- Type: boolean
+ For example, Mutt-ng has the ability to highlight the signature in a different color in the builtin pager.
- Default: yes
+274. sig_on_top
- Availability: POP
+ Type: boolean
- If _\bs_\be_\bt, Mutt-ng will try all available methods. When _\bu_\bn_\bs_\be_\bt, Mutt-ng will only
- fall back to other authentication methods if the previous methods are unavail-
- able. If a method is available but authentication fails, Mutt-ng will not con-
- nect to the POP server.
+ Default: no
- _\b7_\b._\b4_\b._\b2_\b1_\b1 _\bp_\bo_\bp_\b__\ba_\bu_\bt_\bh_\be_\bn_\bt_\bi_\bc_\ba_\bt_\bo_\br_\bs

- Type: string
+275. signature
- Default: ''
+ Type: path
- Availability: POP
+ Default: "˜/.signature"
- This is a colon-delimited list of authentication methods Mutt-ng may attempt to
- use to log in to an POP server, in the order Mutt-ng should try them. Authen-
- tication methods are either ``user'', ``apop'' or any SASL mechanism, eg
- ``digest-md5'', ``gssapi'' or ``cram-md5''.
+ Specifies the filename of your signature, which is appended to all outgoing messages. If the filename ends with a pipe (``|''), it is assumed that filename is a shell command and input should be read from its stdout.
- The Mutt Next Generation E-Mail Client 141
+276. signoff_string
- This parameter is case-insensitive. If this parameter is _\bu_\bn_\bs_\be_\bt (the default)
- Mutt-ng will try all available methods, in order from most-secure to least-
- secure.
+ Type: string
- Example: set pop_authenticators='digest-md5:apop:user'
+ Default: ""
- _\b7_\b._\b4_\b._\b2_\b1_\b2 _\bp_\bo_\bp_\b__\bd_\be_\bl_\be_\bt_\be
+ If set, this string will be inserted before the signature. This is useful for people that want to sign off every message they send with their name.
- Type: quadoption
+ If you want to insert your website's URL, additional contact information or witty quotes into your mails, better use a signature file instead of the signoff string.
- Default: ask-no
+277. simple_search
- Availability: POP
+ Type: string
- If _\bs_\be_\bt, Mutt-ng will delete successfully downloaded messages from the POP
- server when using the ``fetch-mail'' function. When _\bu_\bn_\bs_\be_\bt, Mutt-ng will down-
- load messages but also leave them on the POP server.
+ Default: "˜f %s | ˜s %s"
- _\b7_\b._\b4_\b._\b2_\b1_\b3 _\bp_\bo_\bp_\b__\bh_\bo_\bs_\bt
+ Specifies how Mutt-ng should expand a simple search into a real search pattern. A simple search is one that does not contain any of the ˜ operators. See ``patterns'' for more information on search patterns.
- Type: string
+ For example, if you simply type ``joe'' at a search or limit prompt, Mutt-ng will automatically expand it to the value specified by this variable. For the default value it would be:
- Default: ''
+ ˜f joe | ˜s joe
- Availability: POP
+278. sleep_time
- The name of your POP server for the ``fetch-mail'' function. You can also
- specify an alternative port, username and password, i.e.:
+ Type: number
- [pop[s]://][username[:password]@]popserver[:port]
+ Default: 1
- N\bNo\bot\bte\be:\b: Storing passwords in a configuration file presents a security risk since
- the superuser of your machine may read it regardless of the file's permissions.
+ Specifies time, in seconds, to pause while displaying certain informational messages, while moving from folder to folder and after expunging messages from the current folder. The default is to pause one second, so a value of zero for this option suppresses the pause.
- _\b7_\b._\b4_\b._\b2_\b1_\b4 _\bp_\bo_\bp_\b__\bl_\ba_\bs_\bt
+279. smart_wrap
- Type: boolean
+ Type: boolean
- Default: no
+ Default: yes
- Availability: POP
+ Controls the display of lines longer than the screen width in the internal pager. If set, long lines are wrapped at a word boundary. If unset, lines are simply wrapped at the screen edge. Also see the ``$markers'' variable.
- If this variable is _\bs_\be_\bt, Mutt-ng will try to use the ``LAST'' POP command for
- retrieving only unread messages from the POP server when using the ``fetch-
- mail'' function.
+280. smileys
- _\b7_\b._\b4_\b._\b2_\b1_\b5 _\bp_\bo_\bp_\b__\bm_\ba_\bi_\bl_\b__\bc_\bh_\be_\bc_\bk
+ Type: regular expression
- Type: number
+ Default: "(>From )|(:[-^]?[][)(><}{|/DP])"
- Default: 60
+ The pager uses this variable to catch some common false positives of ``$quote_regexp'', most notably smileys in the beginning of a line
- Availability: POP
+281. smime_ask_cert_label
- The Mutt Next Generation E-Mail Client 142
+ Type: boolean
- This variable configures how often (in seconds) POP should look for new mail.
+ Default: yes
- _\b7_\b._\b4_\b._\b2_\b1_\b6 _\bp_\bo_\bp_\b__\bp_\ba_\bs_\bs
+ This flag controls whether you want to be asked to enter a label for a certificate about to be added to the database or not. It is set by default. (S/MIME only)
- Type: string
+282. smime_ca_location
- Default: ''
+ Type: path
- Availability: POP
+ Default: ""
- Specifies the password for your POP account. If _\bu_\bn_\bs_\be_\bt, Mutt-ng will prompt you
- for your password when you open POP mailbox.
+ This variable contains the name of either a directory, or a file which contains trusted certificates for use with OpenSSL. (S/MIME only)
- N\bNo\bot\bte\be:\b: Storing passwords in a configuration file presents a security risk since
- the superuser of your machine may read it regardless of the file's permissions.

+ Type: path
- Type: quadoption
+ Default: ""
- Default: ask-yes
+ Since there is no pubring/secring as with PGP, Mutt-ng has to handle storage and retrieval of keys by itself. This is very basic right now, and keys and certificates are stored in two different directories, both named as the hash-value retrieved from OpenSSL. There is an index file which contains mailbox-address keyid pairs, and which can be manually edited. This one points to the location of the certificates. (S/MIME only)
- Availability: POP
+284. smime_decrypt_command
- Controls whether or not Mutt-ng will try to reconnect to a POP server when the
- connection is lost.
+ Type: string
- _\b7_\b._\b4_\b._\b2_\b1_\b8 _\bp_\bo_\bp_\b__\bu_\bs_\be_\br
+ Default: ""
- Type: string
+ This format string specifies a command which is used to decrypt application/x-pkcs7-mime attachments.

- _\b7_\b._\b4_\b._\b2_\b1_\b9 _\bp_\bo_\bs_\bt_\b__\bi_\bn_\bd_\be_\bn_\bt_\b__\bs_\bt_\br_\bi_\bn_\bg
+ %c
+ One or more certificate IDs.
- Type: string
+ %a
+ The algorithm used for encryption.
- Default: ''
+ %C
+ CA location: Depending on whether $smime_ca_location points to a directory or file, this expands to "-CApath $smime_ca_location" or "-CAfile $smime_ca_location".
- Similar to the ``_\b$_\ba_\bt_\bt_\br_\bi_\bb_\bu_\bt_\bi_\bo_\bn (section 7.4.18 , page 93)'' variable, Mutt-ng
- will append this string after the inclusion of a message which is being replied
- to.

- Type: quadoption
+ Type: boolean
- Default: ask-yes
+ Default: yes
- The Mutt Next Generation E-Mail Client 143
+ If set (default) this tells Mutt-ng to use the default key for decryption. Otherwise, if manage multiple certificate-key-pairs, Mutt-ng will try to use the mailbox-address to determine the key to use. It will ask you to supply a key, if it can't find one. (S/MIME only)
- Controls whether or not messages are saved in the ``_\b$_\bp_\bo_\bs_\bt_\bp_\bo_\bn_\be_\bd (section

+ Type: string
- Type: path
+ Default: ""
- Default: '~/postponed'
+ This is the default key-pair to use for signing. This must be set to the keyid (the hash-value that OpenSSL generates) to work properly (S/MIME only)
- Mutt-ng allows you to indefinitely ``_\bp_\bo_\bs_\bt_\bp_\bo_\bn_\be (section 7.4.220 , page 142)
- sending a message'' which you are editing. When you choose to postpone a mes-
- sage, Mutt-ng saves it in the mailbox specified by this variable. Also see the

+ This command is used to create encrypted S/MIME messages. (S/MIME only)
- If _\bs_\be_\bt, a shell command to be executed if Mutt-ng fails to establish a connec-
- tion to the server. This is useful for setting up secure connections, e.g. with

- Type: boolean
+ Defines wether to use STARTTLS. If this option is set to ``required'' and the server does not support STARTTLS or there is an error in the TLS Handshake, the connection will fail. Setting this to ``enabled'' will try to start TLS and continue without TLS in case of an error. Muttng still needs to have SSL support enabled in order to use it.
- Default: no
+306. smtp_user
- If _\bu_\bn_\bs_\be_\bt and you are replying to a message sent by you, Mutt-ng will assume
- that you want to reply to the recipients of that message rather than to your-

+ Default: ""
- Type: quadoption
+ Availability: SMTP
- Default: ask-yes
+ Defines the username to use with SMTP AUTH. Setting this variable will cause Mutt-ng to attempt to use SMTP AUTH when sending.
- If _\bs_\be_\bt, when replying to a message, Mutt-ng will use the address listed in the
- ``Reply-To:'' header field as the recipient of the reply. If _\bu_\bn_\bs_\be_\bt, it will
- use the address in the ``From:'' header field instead.
+307. sort
- This option is useful for reading a mailing list that sets the ``Reply-To:''

- Default: no
+ Specifies how the entries in the ``alias'' menu are sorted. The following are legal values:
+ address (sort alphabetically by email address)
+ alias (sort alphabetically by alias name)
+ unsorted (leave in order specified in .muttrc)
- This variable controls whether or not Mutt-ng will display the ``personal''
- name from your aliases in the index menu if it finds an alias that matches the
- message's sender. For example, if you have the following alias:
+309. sort_aux
- alias juser abd30425@somewhere.net (Joe User)
+ Type: sort order
- and then you receive mail which contains the following header:
+ Default: date
- From: abd30425@somewhere.net
+ When sorting by threads, this variable controls how threads are sorted in relation to other threads, and how the branches of the thread trees are sorted. This can be set to any value that ``$sort'' can, except threads (in that case, Mutt-ng will just use date-sent). You can also specify the ``last-'' prefix in addition to ``reverse-'' prefix, but last- must come after reverse-. The last- prefix causes messages to be sorted against its siblings by which has the last descendant, using the rest of sort_aux as an ordering.
- It would be displayed in the index menu as ``Joe User'' instead of
+ For instance, set sort_aux=last-date-received would mean that if a new message is received in a thread, that thread becomes the last one displayed (or the first, if you have set sort=reverse-threads.)

+ Note: For reversed ``$sort'' order $sort_aux is reversed again (which is not the right thing to do, but kept to not break any existing configuration setting).
- ``abd30425@somewhere.net.'' This is useful when the person's e-mail address is
- not human friendly (like CompuServe addresses).

- Mutt-ng will override any such real names with the setting of the _\br_\be_\ba_\bl_\bn_\ba_\bm_\be
- (section 7.4.235 , page 145) variable.
+ This variable is only useful when sorting by threads with ``$strict_threads'' unset. In that case, it changes the heuristic Mutt-ng uses to thread messages by subject. With $sort_re set, Mutt-ng will only attach a message as the child of another message by subject if the subject of the child message starts with a substring matching the setting of ``$reply_regexp''. With $sort_re unset, Mutt-ng will attach the message whether or not this is the case, as long as the non-``$reply_regexp'' parts of both messages are identical.

+ * = can be optionally printed if nonzero
- %M
- Total number of messages shown, i.e. not hidden by a limit. 1)
+ Some of the above sequences can be used to optionally print a string if their value is nonzero. For example, you may only want to see the number of flagged messages if such messages exist, since zero is not particularly meaningful. To optionally print a string based upon one of the above sequences, the following construct is used
- %n
- Number of new messages.
+ %?<sequence_char>?<optional_string>?
- %t
- Number of tagged messages. 1)
+ where sequence_char is a character from the table above, and optional_string is the string you would like printed if sequence_char is nonzero. optional_string may contain other sequences as well as normal text, but you may not nest optional strings.
- 1) These expandos only have a non-zero value for the current mailbox and will
- always be zero otherwise.
+ Here is an example illustrating how to optionally print the number of new messages in a mailbox:
- _\b7_\b._\b4_\b._\b2_\b6_\b1 _\bs_\bi_\bd_\be_\bb_\ba_\br_\b__\bs_\bh_\bo_\br_\bt_\be_\bn_\b__\bh_\bi_\be_\br_\ba_\br_\bc_\bh_\by
+ %?n?%n new messages.?
- Type: boolean
+ Additionally you can switch between two strings, the first one, if a value is zero, the second one, if the value is nonzero, by using the following construct:
- Default: no
+ %?<sequence_char>?<if_string>&<else_string>?
- When _\bs_\be_\bt, the ``hierarchy'' of the sidebar entries will be shortened only if
- they cannot be printed in full length (because ``_\b$_\bs_\bi_\bd_\be_\bb_\ba_\br_\b__\bw_\bi_\bd_\bt_\bh (section
- 7.4.263 , page 152)'' is set to a too low value). For example, if the news-
- group name ``de.alt.sysadmin.recovery'' doesn't fit on the screen, it'll get
- shortened ``d.a.s.recovery'' while ``de.alt.d0'' still would and thus will not
- get shortened.
+ You can additionally force the result of any printf(3)-like sequence to be lowercase by prefixing the sequence character with an underscore (_) sign. For example, if you want to display the local hostname in lowercase, you would use:
- At which characters this compression is done is controled via the _\b$_\bs_\bi_\bd_\be_\b-
- _\bb_\ba_\br_\b__\bb_\bo_\bu_\bn_\bd_\ba_\br_\by (section 7.4.257 , page 151) variable.
+ %_h
- _\b7_\b._\b4_\b._\b2_\b6_\b2 _\bs_\bi_\bd_\be_\bb_\ba_\br_\b__\bv_\bi_\bs_\bi_\bb_\bl_\be
+ If you prefix the sequence character with a colon (:) character, Mutt-ng will replace any dots in the expansion by underscores. This might be helpful with IMAP folders that don't like dots in folder names.

- that you not unset this variable unless your ``signature'' contains just your
- name. The reason for this is because many software packages use ``-- \n'' to
- detect your signature.
+ When unset, non MIME-compliant messages that doesn't have any charset indication in the ``Content-Type:'' header field can be displayed (non MIME-compliant messages are often generated by old mailers or buggy mailers like MS Outlook Express). See also $assumed_charset.
- For example, Mutt-ng has the ability to highlight the signature in a different
- color in the builtin pager.
+ This option also replaces linear-white-space between encoded-word and *text to a single space to prevent the display of MIME-encoded ``Subject:'' header field from being devided into multiple lines.

+ If set, threading will only make use of the ``In-Reply-To:'' and ``References:'' header fields when you ``$sort'' by message threads. By default, messages with the same subject are grouped together in ``pseudo threads.'' This may not always be desirable, such as in a personal mailbox where you might have several unrelated messages with the subject ``hi'' which will get grouped together.

- name is a shell command and input should be read from its stdout.
+ When set, mutt-ng will remove the trailing part of the ``Subject:'' line which matches $strip_was_regex when replying. This is useful to properly react on subject changes and reduce ``subject noise.'' (esp. in Usenet)

+ If set, attachments with flowed format will have their quoting ``stuffed'', i.e. a space will be inserted between the quote characters and the actual text.
- Default: '~f %s | ~s %s'
+332. suspend
- Specifies how Mutt-ng should expand a simple search into a real search pattern.
- A simple search is one that does not contain any of the ~ operators. See
- ``_\bp_\ba_\bt_\bt_\be_\br_\bn_\bs (section 7.2 , page 83)'' for more information on search patterns.
+ Type: boolean
- For example, if you simply type ``joe'' at a search or limit prompt, Mutt-ng
- will automatically expand it to the value specified by this variable. For the
- default value it would be:
+ Default: yes
- ~f joe | ~s joe
+ When unset, Mutt-ng won't stop when the user presses the terminal's susp key, usually CTRL+Z. This is useful if you run Mutt-ng inside an xterm using a command like ``xterm -e muttng.''

- Type: number
+ Type: boolean
- Default: 1
+ Default: no
- Specifies time, in seconds, to pause while displaying certain informational
- messages, while moving from folder to folder and after expunging messages from
- the current folder. The default is to pause one second, so a value of zero for
- this option suppresses the pause.
+ When set, Mutt-ng will generate text/plain; format=flowed attachments. This format is easier to handle for some mailing software, and generally just looks like ordinary text. To actually make use of this format's features, you'll need support in your editor.

+334. thorough_search
- Default: yes
+ Type: boolean
- Controls the display of lines longer than the screen width in the internal
- pager. If _\bs_\be_\bt, long lines are wrapped at a word boundary. If _\bu_\bn_\bs_\be_\bt, lines are
- simply wrapped at the screen edge. Also see the ``_\b$_\bm_\ba_\br_\bk_\be_\br_\bs (section 7.4.127 ,

- _\b7_\b._\b4_\b._\b2_\b7_\b1 _\bs_\bm_\bi_\bl_\be_\by_\bs
+ Affects the ˜b and ˜h search operations described in section ``patterns'' above. If set, the headers and attachments of messages to be searched are decoded before searching. If unset, messages are searched as they appear in the folder.
- Type: regular expression
+335. thread_received
- Default: '(>From )|(:[-^]?[][)(><}{|/DP])'
+ Type: boolean
- The _\bp_\ba_\bg_\be_\br uses this variable to catch some common false positives of

- This variable contains the name of either a directory, or a file which contains
- trusted certificates for use with OpenSSL. (S/MIME only)
+ This variable controls the number of seconds Mutt-ng will wait for a key to be pressed in the main menu before timing out and checking for new mail. A value of zero or less will cause Mutt-ng to never time out.

- Type: path
+ Type: path
- Default: ''
+ Default: ""
- Since there is no pubring/secring as with PGP, Mutt-ng has to handle storage
- and retrieval of keys by itself. This is very basic right now, and keys and
- certificates are stored in two different directories, both named as the hash-
- value retrieved from OpenSSL. There is an index file which contains mailbox-
- address keyid pairs, and which can be manually edited. This one points to the
- location of the certificates. (S/MIME only)
+ This variable allows you to specify where Mutt-ng will place its temporary files needed for displaying and composing messages. If this variable is not set, the environment variable $TMPDIR is used. If $TMPDIR is not set then "/tmp" is used.

- Type: string
+ Type: string
- Default: ''
+ Default: " +TCFL"
- This format string specifies a command which is used to decrypt application/x-
- pkcs7-mime attachments.
+ Controls the character used to indicate mail addressed to you. The first character is the one used when the mail is NOT addressed to your address (default: space). The second is used when you are the only recipient of the message (default: +). The third is when your address appears in the ``To:'' header field, but you are not the only recipient of the message (default: T). The fourth character is used when your address is specified in the ``Cc:'' header field, but you are not the only recipient. The fifth character is used to indicate mail that was sent by you. The sixth character is used to indicate when a mail was sent to a mailing-list you're subscribe to (default: L).

+ If set, this variable specifies the path of the trash folder where the mails marked for deletion will be moved, instead of being irremediably purged.
- The Mutt Next Generation E-Mail Client 156
+ Note: When you delete a message in the trash folder, it is really deleted, so that there is no way to recover mail.

+ Default: ""
- For examples on how to configure these formats, see the smime.rc in the sam-
- ples/ subdirectory which has been installed on your system alongside the docu-
- mentation. (S/MIME only)
+ Setting this variable will cause Mutt-ng to open a pipe to a command instead of a raw socket. You may be able to use this to set up preauthenticated connections to your IMAP/POP3 server. Example:
- _\b7_\b._\b4_\b._\b2_\b7_\b6 _\bs_\bm_\bi_\bm_\be_\b__\bd_\be_\bc_\br_\by_\bp_\bt_\b__\bu_\bs_\be_\b__\bd_\be_\bf_\ba_\bu_\bl_\bt_\b__\bk_\be_\by
+ tunnel="ssh -q mailhost.net /usr/local/libexec/imapd"
- Type: boolean
+ Note: For this example to work you must be able to log in to the remote machine without having to enter a password.
- Default: yes
+342. umask
- If _\bs_\be_\bt (default) this tells Mutt-ng to use the default key for decryption. Oth-
- erwise, if manage multiple certificate-key-pairs, Mutt-ng will try to use the
- mailbox-address to determine the key to use. It will ask you to supply a key,
- if it can't find one. (S/MIME only)

- Type: string
+ Warning: do not set this variable unless you are using a version of sendmail which supports the -B8BITMIME flag (such as sendmail 8.8.x) or in connection with the SMTP support via libESMTP. Otherwise you may not be able to send mail.
- Default: ''
+ When set, Mutt-ng will either invoke ``$sendmail'' with the -B8BITMIME flag when sending 8-bit messages to enable ESMTP negotiation or tell libESMTP to do so.
- This sets the algorithm that should be used for encryption. Valid choices are
- ``des'', ``des3'', ``rc2-40'', ``rc2-64'', ``\frc2-128''.

-
- Some of the above sequences can be used to optionally print a string if their
- value is nonzero. For example, you may only want to see the number of flagged
- messages if such messages exist, since zero is not particularly meaningful. To
- optionally print a string based upon one of the above sequences, the following
- construct is used
-
- %?<sequence_char>?<optional_string>?
-
- The Mutt Next Generation E-Mail Client 167
-
- where _\bs_\be_\bq_\bu_\be_\bn_\bc_\be_\b__\bc_\bh_\ba_\br is a character from the table above, and _\bo_\bp_\bt_\bi_\bo_\bn_\ba_\bl_\b__\bs_\bt_\br_\bi_\bn_\bg is
- the string you would like printed if _\bs_\be_\bq_\bu_\be_\bn_\bc_\be_\b__\bc_\bh_\ba_\br is nonzero. _\bo_\bp_\bt_\bi_\bo_\bn_\ba_\bl_\b__\bs_\bt_\br_\bi_\bn_\bg
- m\bma\bay\by contain other sequences as well as normal text, but you may n\bno\bot\bt nest
- optional strings.
-
- Here is an example illustrating how to optionally print the number of new mes-
- sages in a mailbox:
-
- %?n?%n new messages.?
-
- Additionally you can switch between two strings, the first one, if a value is
- zero, the second one, if the value is nonzero, by using the following con-
- struct:
-
- %?<sequence_char>?<if_string>&<else_string>?
-
- You can additionally force the result of any printf(3)-like sequence to be low-
- ercase by prefixing the sequence character with an underscore (_) sign. For
- example, if you want to display the local hostname in lowercase, you would use:
-
- %_h
-
- If you prefix the sequence character with a colon (:) character, Mutt-ng will
- replace any dots in the expansion by underscores. This might be helpful with
- IMAP folders that don't like dots in folder names.

- _\b7_\b._\b4_\b._\b3_\b2_\b3 _\bs_\bu_\bs_\bp_\be_\bn_\bd
-
- Type: boolean
-
- Default: yes
-
- When _\bu_\bn_\bs_\be_\bt, Mutt-ng won't stop when the user presses the terminal's _\bs_\bu_\bs_\bp key,
- usually CTRL+Z. This is useful if you run Mutt-ng inside an xterm using a com-
- mand like ``xterm -e muttng.''

- _\b7_\b._\b4_\b._\b3_\b2_\b4 _\bt_\be_\bx_\bt_\b__\bf_\bl_\bo_\bw_\be_\bd
-
- Type: boolean
-
- Default: no
-
- When _\bs_\be_\bt, Mutt-ng will generate text/plain; format=flowed attachments. This
- format is easier to handle for some mailing software, and generally just looks
- like ordinary text. To actually make use of this format's features, you'll
- need support in your editor.
-
- Note that _\b$_\bi_\bn_\bd_\be_\bn_\bt_\b__\bs_\bt_\br_\bi_\bn_\bg (section 7.4.115 , page 115) is ignored when this
- option is set.

-
- Default: no
-
- Affects the ~b and ~h search operations described in section ``_\bp_\ba_\bt_\bt_\be_\br_\bn_\bs (sec-
- tion 7.2 , page 83)'' above. If _\bs_\be_\bt, the headers and attachments of messages
- to be searched are decoded before searching. If _\bu_\bn_\bs_\be_\bt, messages are searched
- as they appear in the folder.

-
- When _\bs_\be_\bt, Mutt-ng uses the date received rather than the date sent to thread
- messages by subject.
-
- _\b7_\b._\b4_\b._\b3_\b2_\b7 _\bt_\bi_\bl_\bd_\be

-
- _\b7_\b._\b4_\b._\b3_\b2_\b9 _\bt_\bm_\bp_\bd_\bi_\br
-
- Type: path
-
- Default: ''
-
- This variable allows you to specify where Mutt-ng will place its temporary
- files needed for displaying and composing messages. If this variable is not
- set, the environment variable $TMPDIR is used. If $TMPDIR is not set then
- '/tmp' is used.
-
- _\b7_\b._\b4_\b._\b3_\b3_\b0 _\bt_\bo_\b__\bc_\bh_\ba_\br_\bs
-
- Type: string
-
- Default: ' +TCFL'
-
- Controls the character used to indicate mail addressed to you. The first char-
- acter is the one used when the mail is NOT addressed to your address (default:
- space). The second is used when you are the only recipient of the message
- (default: +). The third is when your address appears in the ``To:'' header
- field, but you are not the only recipient of the message (default: T). The
- fourth character is used when your address is specified in the ``Cc:'' header
- field, but you are not the only recipient. The fifth character is used to
- indicate mail that was sent by _\by_\bo_\bu. The sixth character is used to indicate
- when a mail was sent to a mailing-list you're subscribe to (default: L).
-
- _\b7_\b._\b4_\b._\b3_\b3_\b1 _\bt_\br_\ba_\bs_\bh
-
- Type: path
-
- Default: ''
-
- If _\bs_\be_\bt, this variable specifies the path of the trash folder where the mails
- marked for deletion will be moved, instead of being irremediably purged.
-
- N\bNo\bot\bte\be: When you delete a message in the trash folder, it is really deleted, so
- that there is no way to recover mail.

-
- Type: string

-
- Setting this variable will cause Mutt-ng to open a pipe to a command instead of
- a raw socket. You may be able to use this to set up preauthenticated connec-
- tions to your IMAP/POP3 server. Example:
-
- tunnel='ssh -q mailhost.net /usr/local/libexec/imapd'
-
- N\bNo\bot\bte\be:\b: For this example to work you must be able to log in to the remote machine
- without having to enter a password.

- _\b7_\b._\b4_\b._\b3_\b3_\b3 _\bu_\bm_\ba_\bs_\bk
-
- Type: number
-

- W\bWa\bar\brn\bni\bin\bng\bg:\b: do not set this variable unless you are using a version of sendmail
- which supports the -B8BITMIME flag (such as sendmail 8.8.x) or in connection
- with the SMTP support via libESMTP. Otherwise you may not be able to send
- mail.
-
- When _\bs_\be_\bt, Mutt-ng will either invoke ``_\b$_\bs_\be_\bn_\bd_\bm_\ba_\bi_\bl (section 7.4.254 , page
- 150)'' with the -B8BITMIME flag when sending 8-bit messages to enable ESMTP
- negotiation or tell libESMTP to do so.

-
- Type: boolean
-
- Default: yes
-
- When _\bs_\be_\bt, Mutt-ng will qualify all local addresses (ones without the @host por-
- tion) with the value of ``_\b$_\bh_\bo_\bs_\bt_\bn_\ba_\bm_\be (section 7.4.95 , page 110)''. If _\bu_\bn_\bs_\be_\bt,

- Type: boolean
-
- Default: yes
-
- When _\bs_\be_\bt, Mutt-ng will generate the ``From:'' header field when sending mes-
- sages. If _\bu_\bn_\bs_\be_\bt, no ``From:'' header field will be generated unless the user
- explicitly sets one using the ``_\bm_\by_\b__\bh_\bd_\br (section 3.16 , page 37)'' command.

-
- When _\bs_\be_\bt, Mutt-ng will show you international domain names decoded.
-
- N\bNo\bot\bte\be:\b: You can use IDNs for addresses even if this is _\bu_\bn_\bs_\be_\bt. This variable only
- affects decoding.
-
- _\b7_\b._\b4_\b._\b3_\b3_\b9 _\bu_\bs_\be_\b__\bi_\bp_\bv_\b6
-
- Type: boolean
-
- Default: yes
-
- When _\bs_\be_\bt, Mutt-ng will look for IPv6 addresses of hosts it tries to contact.
- If this option is _\bu_\bn_\bs_\be_\bt, Mutt-ng will restrict itself to IPv4 addresses. Nor-
- mally, the default should work.
-

- Controls whether Mutt-ng will ask you to press a key after _\bs_\bh_\be_\bl_\bl_\b- _\be_\bs_\bc_\ba_\bp_\be, _\bp_\bi_\bp_\be_\b-
- _\bm_\be_\bs_\bs_\ba_\bg_\be, _\bp_\bi_\bp_\be_\b-_\be_\bn_\bt_\br_\by, _\bp_\br_\bi_\bn_\bt_\b-_\bm_\be_\bs_\bs_\ba_\bg_\be, and _\bp_\br_\bi_\bn_\bt_\b-_\be_\bn_\bt_\br_\by commands.
-
- It is also used when viewing attachments with ``_\ba_\bu_\bt_\bo_\b__\bv_\bi_\be_\bw (section 5.4 , page
- 78)'', provided that the corresponding mailcap entry has a needsterminal flag,
- and the external program is interactive.
-
- When _\bs_\be_\bt, Mutt-ng will always ask for a key. When _\bu_\bn_\bs_\be_\bt, Mutt-ng will wait for
-
- The Mutt Next Generation E-Mail Client 173
-
- a key only if the external command returned a non-zero status.
-
- _\b7_\b._\b4_\b._\b3_\b4_\b2 _\bw_\be_\be_\bd

-
- Controls whether searches wrap around the end of the mailbox.
-
- When _\bs_\be_\bt, searches will wrap around the first (or last) message. When _\bu_\bn_\bs_\be_\bt,
- searches will not wrap.

- _\b7_\b._\b4_\b._\b3_\b4_\b6 _\bw_\br_\bi_\bt_\be_\b__\bi_\bn_\bc
-
- Type: number
-
- Default: 10
-
- When writing a mailbox, a message will be printed every _\bw_\br_\bi_\bt_\be_\b__\bi_\bn_\bc messages to

- used to set the title when leaving mutt-ng. For terminal-based programs,
- there's no easy and portable way to read the current title so mutt-ng cannot
- read it upon startup and restore it when exiting.
-
- Based on the xterm FAQ, the following might work:
-
- set xterm_leave = '`test x$DISPLAY != x && xprop -id $WINDOWID | grep WM_NAME |
