Replying + mutt-ng offers different screens of which every has its special + purpose: - 6.3. Editing the message header + * The _i_n_d_e_x displays the contents of the currently opened mailbox. + * The _p_a_g_e_r is responsible for displaying messages, that is, the + header, the body and all attached parts. + * The _f_i_l_e_ _b_r_o_w_s_e_r offers operations on and displays information of + all folders mutt-ng should watch for mail. + * The _s_i_d_e_b_a_r offers a permanent view of which mailboxes contain how + many total, new and/or flagged mails. + * The _h_e_l_p_ _s_c_r_e_e_n lists for all currently available commands how to + invoke them as well as a short description. + * The _c_o_m_p_o_s_e menu is a comfortable interface take last actions + before sending mail: change subjects, attach files, remove + attachements, etc. + * The _a_t_t_a_c_h_e_m_e_n_t menu gives a summary and the tree structure of the + attachements of the current message. + * The _a_l_i_a_s menu lists all or a fraction of the aliases a user has + defined. + * The _k_e_y menu used in connection with encryption lets users choose + the right key to encrypt with. - 6.4. Using Mutt-ng with PGP + When mutt-ng is started without any further options, it'll open the + users default mailbox and display the index. - 6.5. Sending anonymous messages via mixmaster +1.2. Configuration - 7. Forwarding and Bouncing Mail + Mutt-ng does _n_o_t feature an internal configuration interface or menu + due to the simple fact that this would be too complex to handle + (currently there are several _h_u_n_d_r_e_d variables which fine-tune the + behaviour.) - 8. Postponing Mail + Mutt-ng is configured using configuration files which allow users to + add comments or manage them via version control systems to ease + maintenance. - 3. Configuration + 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. - 1. Locations of Configuration Files +1.3. Functions - 2. Basic Syntax of Initialization Files + 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. - 3. Expansion within variables +1.4. Interaction - 3.1. Commands' Output + Mutt-ng has two basic concepts of user interaction: - 3.2. Environment Variables + 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 _h_o_o_k_s. + 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. - 3.3. Configuration Variables +1.5. Modularization - 3.4. Self-Defined Variables + 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. - 3.5. Pre-Defined Variables +1.6. Patterns - 3.6. Type Conversions + 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. - 4. Defining/Using aliases +2. Screens and Menus - 5. Changing the default key bindings +2.1. Index - 6. Defining aliases for character sets + 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. - 7. Setting variables based upon mailbox +2.2. Pager - 8. Keyboard macros + 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. - 9. Using color and mono video attributes + 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. + + 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. + +2.3. File Browser + + 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. + +2.4. Sidebar + + 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. + +2.5. Help + + 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). + +2.6. Compose Menu + + 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. + +2.7. Alias Menu + + 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. + +2.8. Attachment Menu + + 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. + +2.9. Key Menu - 10. Ignoring (weeding) unwanted message headers + FIXME - 11. Alternative addresses +3. Moving Around in Menus - 12. Format = Flowed + Information is presented in menus, very similar to ELM. Here is a + tableshowing the common keys used to navigate menus in Mutt-ng. - 12.1. Introduction + _T_a_b_l_e_ _2_._1_._ _M_o_s_t_ _c_o_m_m_o_n_l_y_ _u_s_e_d_ _m_o_v_e_m_e_n_t_ _b_i_n_d_i_n_g_s + Key Function Description + j or Down move to the next entry + k or Up move to the previous entry + z or PageDn go to the next page + Z or PageUp go to the previous page + = or Home jump to the first entry + * or End jump to the last entry + q exit the current menu + ? list all key bindings for the current menu - 12.2. Receiving: Display Setup +4. Editing Input Fields - 12.3. Sending + 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. - 12.4. Additional Notes + _T_a_b_l_e_ _2_._2_._ _L_i_n_e_ _E_d_i_t_o_r_ _F_u_n_c_t_i_o_n_s + Key Function Description + C-A or Home move to the start of the line + C-B or Left move back one char + E-B move back one word + C-D or Delete delete the char under the cursor + C-E or End move to the end of the line + C-F or Right move forward one char + E-F move forward one word + Tab complete filename or alias + C-T complete address with query + C-K delete to the end of the line + E-d delete to the end of the word + C-W kill the word in front of the cursor + C-U delete entire line + C-V quote the next typed key + Up recall previous string from history + Down recall next string from history + BackSpace kill the char in front of the cursor + E-u convert word to upper case + E-l convert word to lower case + E-c capitalize the word + C-G abort + Return finish editing - 13. Mailing lists + You can remap the _e_d_i_t_o_r functions using the bbiinndd command. For + example, to make the _D_e_l_e_t_e key delete the character in front of the + cursor rather than under, you could use - 14. Using Multiple spool mailboxes + bind editor backspace - 15. Defining mailboxes which receive mail +5. Reading Mail - The Index and Pager - 16. User defined headers + Similar to many other mail clients, there are two modes in which mail + isread 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.'' - 17.

Patterns + F + message is from you - 2.1. Complex Patterns + L + message is sent to a subscribed mailing list - 2.2. Patterns and Dates +5.2. The Pager - 3. Format Strings + By default, Mutt-ng uses its builtin pager to display the body of + messages. The pager is very similar to the Unix program _l_e_s_s though + not nearly as featureful. + + _T_a_b_l_e_ _2_._4_._ _M_o_s_t_ _c_o_m_m_o_n_l_y_ _u_s_e_d_ _P_a_g_e_r_ _B_i_n_d_i_n_g_s + Key Function Description + 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) + E-/ 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 _i_n_d_e_x are available in the + pager, such as _d_e_l_e_t_e_-_m_e_s_s_a_g_e or _c_o_p_y_-_m_e_s_s_a_g_e (this is one advantage + over using an external pager to view messages). + + Also, the internal pager supports a couple other advanced features. + For one, it will accept and translate the ``standard'' nroff sequences + forbold and underline. These sequences are a series of either the + letter, backspace (C-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 ccoolloorr objects to + specify a color or mono attribute for them. + + 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 (see table below for possible values for Ps). + + _T_a_b_l_e_ _2_._5_._ _A_N_S_I_ _E_s_c_a_p_e_ _S_e_q_u_e_n_c_e_s + Value Attribute + 0 All Attributes Off + 1 Bold on + 4 Underline on + 5 Blink on + 7 Reverse video on + 3x Foreground color is x (see table below) + 4x Background color is x (see table below) - 3.1. Introduction + _T_a_b_l_e_ _2_._6_._ _A_N_S_I_ _C_o_l_o_r_s + Number Color + 0 black + 1 red + 2 green + 3 yellow + 4 blue + 5 magenta + 6 cyan + 7 white - 3.2. Conditional Expansion + Mutt-ng uses these attributes for handling text/enriched messages, and + they can also be used by an external aauuttoo__vviieeww script for highlighting + purposes. _N_o_t_e_: 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. + +5.3. Threaded Mode + + When the mailbox is ssoorrtteedd by _t_h_r_e_a_d_s ,there are a few additional + functions available in the _i_n_d_e_x and _p_a_g_e_r modes. + + _T_a_b_l_e_ _2_._7_._ _M_o_s_t_ _c_o_m_m_o_n_l_y_ _u_s_e_d_ _t_h_r_e_a_d_-_r_e_l_a_t_e_d_ _b_i_n_d_i_n_g_s + Key Function Description + C-D delete all messages in the current thread + C-U undelete all messages in the current thread + C-N jump to the start of the next thread + C-P jump to the start of the previous thread + C-R mark the current thread as read + E-d delete all messages in the current subthread + E-u undelete all messages in the current + subthread + E-n jump to the start of the next subthread + E-p jump to the start of the previous subthread + E-r mark the current subthread as read + E-t toggle the tag on the current thread + E-v toggle collapse for the current thread + E-V toggle collapse for all threads + P jump to parent message in thread + + _N_o_t_e_: 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 onthe screen. + See %M in $$iinnddeexx__ffoorrmmaatt. + + For example, you could use %?M?(#%03M)&(%4l)? in $$iinnddeexx__ffoorrmmaatt to + optionally display the number of hidden messages if the thread is + collapsed. - 3.3. Modifications and Padding + See also the $$ssttrriicctt__tthhrreeaaddss variable. - 4. Using Tags +5.4. Miscellaneous Functions - 5. Using Hooks + (default: a) - 5.1. Message Matching in Hooks + Creates a new alias based upon the current message (or prompts for a + new one). Once editing is complete, an aalliiaass command is added to the + file specified by the $$aalliiaass__ffiillee variable for future use. _N_o_t_e_: + Specifying an $$aalliiaass__ffiillee does not add the aliases specified there-in, + you must also ssoouurrccee the file. - 6. Using the sidebar + (default: E-P) - 7. External Address Queries + 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 function's effect. - 8. Mailbox Formats + (default: h) - 9. Mailbox Shortcuts + Toggles the weeding of message header fields specified by iiggnnoorree + commands. - 10. Handling Mailing Lists + (default: e) - 11. Editing threads + 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. - 11.1. Linking threads + (default: ) (default: C-E on the attachment menu, and in + the pager and index menus; C-T on the compose menu) - 11.2. Breaking threads + 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 aattttaacchh--mmeennuu, you can + change any attachment's content type. These changes are not + persistent, and get lost upon changing folders. - 12. Delivery Status Notification (DSN) Support + Note that this command is also available on the ccoommppoossee--mmeennuu .There, + it's used to fine-tune the properties of attachments you are going to + send. - 13. POP3 Support (OPTIONAL) + (default: :) - 14. IMAP Support (OPTIONAL) + 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 mmaaccrroo to change settings on the fly. - 14.1. The Folder Browser + (default: C-K) - 14.2. Authentication + This command extracts PGP public keys from the current or tagged + message(s) and adds them to your PGP public key ring. - 15. NNTP Support (OPTIONAL) + (default: C-F) - 15.1. Again: Scoring + This command wipes the passphrase(s) from memory. It is useful, if you + misspelled the passphrase. - 16. SMTP Support (OPTIONAL) + (default: L) - 17. Managing multiple IMAP/POP/NNTP accounts (OPTIONAL) + Reply to the current or tagged message(s) by extracting any addresses + which match the regular expressions given by the lliissttss commands, but + also honor any Mail-Followup-To header(s) if the $$hhoonnoorr__ffoolllloowwuupp__ttoo + 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. - 18. Start a WWW Browser on URLs (EXTERNAL) + (default: ) - 19. Compressed folders Support (OPTIONAL) + Asks for an external Unix command and pipes the current or tagged + message(s) to it. The variables $$ppiippee__ddeeccooddee, $$ppiippee__sspplliitt, + $$ppiippee__ddeeccooddee and $$wwaaiitt__kkeeyy control the exact behavior of this + function. - 19.1. Open a compressed mailbox for reading + (default: E-e) - 19.2. Write a compressed mailbox + 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 $$wweeeedd + variable. - 19.3. Append a message to a compressed mailbox + This function is also available from the attachment menu. You can use + this to easily resend a message which was included with a bounce + message as a message/rfc822 body part. - 19.4. Encrypted folders + (default: !) - 5. Mutt-ng's MIME Support + Asks for an external Unix command and executes it. The $$wwaaiitt__kkeeyy 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. - 1. Using MIME in Mutt + (default: T) - 1.1. Viewing MIME messages in the pager + The _p_a_g_e_r uses the $$qquuoottee__rreeggeexxpp variable to detect quoted text when + displaying the body of the message. This function toggles the + displayof 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. - 1.2. The Attachment Menu + (default: S) - 1.3. The Compose Menu + This function will go to the next line of non-quoted text which come + after a line of quoted text in the internal pager. - 2. MIME Type configuration with mime.types +6. Sending Mail - 3. MIME Viewer configuration with mailcap + The following bindings are available in the _i_n_d_e_x for sending + messages. - 3.1. The Basics of the mailcap file + _T_a_b_l_e_ _2_._8_._ _M_o_s_t_ _c_o_m_m_o_n_l_y_ _u_s_e_d_ _M_a_i_l_ _C_o_m_p_o_s_i_t_i_o_n_ _B_i_n_d_i_n_g_s + Key Function Description + m compose a new message + r reply to sender + g reply to all recipients + L reply to mailing list address + f forward message + b bounce (remail) message + E-k mail a PGP public key to someone - 3.2. Secure use of mailcap + 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 ffoorrwwaarrddiinngg--mmaaiill. - 3.3. Advanced mailcap Usage +6.1. Composing new messages - 3.4. Example mailcap files + 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: - 4. MIME Autoview +To: - 5. MIME Multipart/Alternative + 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. - 6. Attachment Searching and Counting + The editor that is called is selected in the following way: you can + e.g. set it in the mutt-ng configuration: - 7. MIME Lookup +set editor = "vim +/^$/ -c ':set tw=72'" +set editor = "nano" +set editor = "emacs" - 6. Security Considerations + 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(1) 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 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 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 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.

Simple Replies + + 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. + +On Mon, Mar 07, 2005 at 05:02:12PM +0100, Michael Svensson wrote: +> Bill, can you please send last month's progress report to Mr. +> Morgan?

Other + 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. - 7. Reference +6.2.2. Group Replies - 1. Command line options + 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 functionalityensures 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. - 2. Patterns +6.2.3. List Replies - 3. Configuration Commands + 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. - 4. Configuration variables + 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. - 5. Functions +lists linuxevent@luga\.at vuln-dev@ mutt-ng-users@ - 5.1. generic + 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. - 5.2. index +6.3. Editing the message header - 5.3. pager + When editing the header of your outgoing message, there are a couple + of special features available. - 5.4. alias + If you specify Fcc:_f_i_l_e_n_a_m_e Mutt-ng will pick up _f_i_l_e_n_a_m_e just as if + you had used the _e_d_i_t_-_f_c_c function in the _c_o_m_p_o_s_e menu. - 5.5. query + You can also attach files to your message by specifying +Attach: filename [description] - 5.6. attach + where _f_i_l_e_n_a_m_e is the file to attach and _d_e_s_c_r_i_p_t_i_o_n is an optional + string to use as the description of the attached file. - 5.7. compose + When replying to messages, if you remove the _I_n_-_R_e_p_l_y_-_T_o_: field from + the header field, Mutt-ng will not generate a _R_e_f_e_r_e_n_c_e_s_: field, which + allows you to create a new message thread. - 5.8. postpone + Also see the $$eeddiitt__hheeaaddeerrss and $$eeddiittoorr__hheeaaddeerrss variables - 5.9. browser +6.4. Using Mutt-ng with PGP - 5.10. pgp + If you want to use PGP, you can specify +Pgp: [E | S | S id] - 5.11. editor + ``E'' encrypts, ``S'' signs and ``S'' signs with the given key, + setting $$ppggpp__ssiiggnn__aass permanently. - 5.12. sidebar + If you have told mutt to PGP encrypt a message, it will guide you + through a key selection process when you try to send the message. + Mutt-ng will not ask you any questions about keys which have a + certified user ID matching one of the message recipients' mail + addresses. However, there may be situations in which there are several + keys, weakly certified user ID fields, or where no matching keys can + be found. - A. Acknowledgments + In these cases, you are dropped into a menu with a list of keys from + which you can select one. When you quit this menu, or mutt can't find + any matching keys, you are prompted for a user ID. You can, as + usually, abort this prompt using C-G. When you do so, mutt will return + to the compose screen. - B. Hacking Documentation + Once you have successfully finished the key selection, the message + will be encrypted using the selected public keys, and sent out. - Index + Most fields of the entries in the key selection menu (see also + $$ppggpp__eennttrryy__ffoorrmmaatt) have obvious meanings. But some explanations on the + capabilities, flags, and validity fields are in order. - List of Tables + The flags sequence (%f) will expand to one of the following flags: - 2.1. Most commonly used movement bindings + _T_a_b_l_e_ _2_._1_0_._ _P_G_P_ _K_e_y_ _M_e_n_u_ _F_l_a_g_s + Flag Description + 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. - 2.2. Line Editor Functions + The capabilities field (%c) expands to a two-character + sequencerepresenting 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. + + 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. + + 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. + +6.5. Sending anonymous messages via mixmaster - 2.3. Most commonly used Index Bindings + 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. - 2.4. Most commonly used Pager Bindings + 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. - 2.5. ANSI Escape Sequences + 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. - 2.6. ANSI Colors + 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. + + Note that different remailers do have different capabilities, + indicated in the %c entry of the remailer menu lines (see + $$mmiixx__eennttrryy__ffoorrmmaatt). 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. - 2.7. Most commonly used thread-related bindings +7. Forwarding and Bouncing Mail - 2.8. Most commonly used Mail Composition Bindings + Often, it is necessary to forward mails to other people. Therefore, + mutt-ng supports forwarding messages in two different ways. - 2.9. Most commonly used Compose Menu Bindings + 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: - 2.10. PGP Key Menu Flags +----- Forwarded message from Lucas User ----- - 3.1.

Reference: Obsolete Variables + 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. - 7.4. Reference: Default Generic Function Bindings + The second mode of forwarding emails with mutt-ng is the so-called + _b_o_u_n_c_i_n_g: 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. - 7.5. Reference: Default Index Function Bindings + 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. - 7.6. Reference: Default Pager Function Bindings +8. Postponing Mail - 7.7. Reference: Default Alias Menu Function Bindings + At times it is desirable to delay sending a message that you have + already begun to compose. When the _p_o_s_t_p_o_n_e_-_m_e_s_s_a_g_e function is used + in the _c_o_m_p_o_s_e menu, the body of your message and attachments are + stored in the mailbox specified by the $$ppoossttppoonneedd variable. This means + that you can recall the message even if you exit Mutt-ng and then + restart it at a later time. - 7.8. Reference: Default Query Menu Function Bindings + 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 _c_o_m_p_o_s_e a + new message from the _i_n_d_e_x or _p_a_g_e_r you will be prompted if postponed + messages exist. If multiple messages are currently postponed, the + _p_o_s_t_p_o_n_e_d menu will pop up and you can select which message you would + like to resume. - 7.9. Reference: Default Attachment Menu Function Bindings + _N_o_t_e_: 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. - 7.10.

Reference: Default Editor Function Bindings + 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'' ccoommmmaannddlliinnee 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. - 7.15. Referene: Default Sidebar Function Bindings + .muttrc (or .muttngrc for Mutt-ng) is the file where you will usually + place your ccoommmmaannddss to configure Mutt-ng. -Chapter 1. Introduction +2. Basic Syntax of Initialization Files - Table of Contents + An initialization file consists of a series of ccoommmmaannddss. 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- + + 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 + + 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 _n_o_t for single quotes. + + \ 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" + + ``\\'' means to insert a literal ``\'' into the line. ``\n'' and + ``\r'' have their usual C meanings of linefeed and carriage-return, + respectively. - 1. Overview + 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. - 2. Mutt-ng Home Page + 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 ``#''. - 3. Mailing Lists +# folder-hook . \ +set realname="Michael \"MuttDude\" Elkins" - 4. Software Distribution Sites + 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! - 5. IRC + Abstract example: - 6. Weblog +line1\ +line2a # line2b\ +line3\ +line4 +line5 - 7. Copyright + 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. - 8. Manual Conventions + The commands understood by mutt are explained in the next paragraphs. + For a complete list, see the ccoommmmaannddss. -1. Overview +3. Expansion within variables - Mutt-ng is a small but very powerful text-based MIME mail client. Mutt-ng - is highly configurable, and is well suited to the mail power user with - advanced features like key bindings, keyboard macros, mail threading, - regular expression searches and a powerful pattern matching language for - selecting groups of messages. + Besides just assign static content to variables, there's plenty of + ways of adding external and more or less dynamic content. - This documentation additionally contains documentation to Mutt-NG ,a fork - from Mutt with the goal to fix all the little annoyances of Mutt, to - integrate all the Mutt patches that are floating around in the web, and to - add other new features. Features specific to Mutt-ng will be discussed in - an extra section. Don't be confused when most of the documentation talk - about Mutt and not Mutt-ng, Mutt-ng contains all Mutt features, plus many - more. +3.1. Commands' Output -2. Mutt-ng Home Page + 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` -3. Mailing Lists + 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. - o : This is where the mutt-ng user - support happens. +3.2. Environment Variables - o : The development mailing list for - mutt-ng + 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 ``$'' sign. + For example, -4. Software Distribution Sites +set record=+sent_on_$HOSTNAME - So far, there are no official releases of Mutt-ng, but you can download - daily snapshots from + sets the $$rreeccoorrdd variable to the string _+_s_e_n_t___o_n__ and appends the + value of the evironment variable $HOSTNAME. -5.

Execute man [section] [name] to view the manual page. + to re-use the command sequence as in: - o Keys are presented in the following way: ordinary keys are just given - as-is, e.g. q. Control characters are prefixed with C- (e.g. the - screen can be redraw by pressing C-L) and E- for Escape, e.g. a folder - can be opened read-only with E-c. +macro index "$user_manualcmd | grep '\^[ ]\\+~. '" "Show Patterns" - If, while reading this fine manual, you find any inconsistencies of - whatever kind, please contact the developers via - to report it. + 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. -Chapter 2. Getting Started + 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. - Table of Contents + The complete removal is done via the unset keyword. - 1.

File Browser + 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. - 2.4. Sidebar + _P_l_e_a_s_e_ _c_o_n_s_u_l_t_ _t_h_e_ _l_o_c_a_l_ _c_o_p_y_ _o_f_ _y_o_u_r_ _m_a_n_u_a_l_ _f_o_r_ _t_h_e_i_r_ _v_a_l_u_e_s_ _a_s_ _t_h_e_y + _m_a_y_ _d_i_f_f_e_r_ _f_r_o_m_ _d_i_f_f_e_r_e_n_t_ _m_a_n_u_a_l_ _s_o_u_r_c_e_s_.

Moving Around in Menus + which works everywhere if a manual is installed. - 4. Editing Input Fields + 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. - 5. Reading Mail - The Index and Pager + For example, the statement - 5.1. The Message Index +folder-hook . "set user_current_folder = $muttng_folder_name" - 5.2.

Postponing Mail +4. Defining/Using aliases -1. Basic Concepts + Usage: alias_k_e_y_ _a_d_d_r_e_s_s_ _[_,_ _a_d_d_r_e_s_s_,_._._._] - 1.1. Screens and Menus + 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. - mutt-ng offers different screens of which every has its special purpose: + _N_o_t_e_: if you want to create an alias for a group (by specifying more + than one address), you _m_u_s_t separate the addresses with a comma + (``,''). - o The index displays the contents of the currently opened mailbox. + To remove an alias or aliases (``*'' means all aliases): - o The pager is responsible for displaying messages, that is, the header, - the body and all attached parts. + Usage: unalias_[_*_ _|_ _k_e_y_ _._._._ _] - o The file browser offers operations on and displays information of all - folders mutt-ng should watch for mail. +alias muttdude me@cs.hmc.edu (Michael Elkins) +alias theguys manny, moe, jack - o The sidebar offers a permanent view of which mailboxes contain how - many total, new and/or flagged mails. + 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 ssoouurrccee. Consequently, you + can have multiple alias files, or you can have all aliases defined in + your muttrc. - o The help screen lists for all currently available commands how to - invoke them as well as a short description. + On the other hand, the function can use only one file, + the one pointed to by the $$aalliiaass__ffiillee variable (which is ~/.muttrc by + default). This file is not special either, in the sense that Mutt-ng + will happily append aliases to any file, but in order for the new + aliases to take effect you need to explicitly ssoouurrccee this file too. - o The compose menu is a comfortable interface take last actions before - sending mail: change subjects, attach files, remove attachements, etc. + For example: - o The attachement menu gives a summary and the tree structure of the - attachements of the current message. +source /usr/local/share/Mutt-ng.aliases +source ~/.mail_aliases +set alias_file=~/.mail_aliases - o The alias menu lists all or a fraction of the aliases a user has - defined. + To use aliases, you merely use the alias at any place in mutt where + muttprompts for addresses, such as the _T_o_: or _C_c_: prompt. You can also + enter aliases in your editor at the appropriate headers if you have + the $$eeddiittoorr__hheeaaddeerrss variable set. - o The key menu used in connection with encryption lets users choose the - right key to encrypt with. + 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. - When mutt-ng is started without any further options, it'll open the users - default mailbox and display the index. + In the alias menu, you can select as many aliases as you want with the + _s_e_l_e_c_t_-_e_n_t_r_y key (default: RET), and use the _e_x_i_t key (default: q) to + return to the address prompt. - 1.2. Configuration +5. Changing the default key bindings - 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.) + Usage: bind_m_a_p_ _k_e_y_ _f_u_n_c_t_i_o_n - Mutt-ng is configured using configuration files which allow users to add - comments or manage them via version control systems to ease maintenance. + This command allows you to change the default key bindings (operation + invoked when pressing a key). - 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. + _m_a_p specifies in which menu the binding belongs. Multiple maps may be + specified by separating them with commas (no additional whitespace + isallowed). The currently defined maps are: - 1.3. Functions + 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. - 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. + 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). - 1.4. Interaction + attach + The attachment menu is used to access the attachments on + received messages. - Mutt-ng has two basic concepts of user interaction: + browser + The browser is used for both browsing the local directory + structure, and for listing all of your incoming mailboxes. - 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. + editor + The editor is the line-based editor the user enters text data. - 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. + index + The index is the list of messages contained in a mailbox. - 1.5. Modularization + compose + The compose menu is the screen used when sending a new message. - 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. + pager + The pager is the mode used to display message/attachment data, + and help listings. - 1.6. Patterns + pgp + The pgp menu is used to select the OpenPGP keys used for + encrypting outgoing messages. - 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. + 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. -2. Screens and Menus + _k_e_y is the key (or key sequence) you wish to bind. To specify a + control character, use the sequence _\_C_x, 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 _\_C_A, _\_C_a, + _\_c_A and _\_c_a are all equivalent. An alternative form is to specify the + key as a three digit octal number prefixed with a ``\'' (for example + _\_1_7_7 is equivalent to _\_c_?). - 2.1. Index + In addition, _k_e_y may consist of: - 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. + _T_a_b_l_e_ _3_._1_._ _A_l_t_e_r_n_a_t_i_v_e_ _K_e_y_ _N_a_m_e_s + Sequence Description + \t tab + tab + backtab / shift-tab + \r carriage return + \n newline + \e escape + escape + up arrow + down arrow + left arrow + right arrow + Page Up + Page Down + Backspace + Delete + Insert + Enter + Return + Home + End + Space bar + function key 1 + function key 10 - 2.2. Pager + _k_e_y does not need to be enclosed in quotes unless it contains a space + (`` ''). - 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. + _f_u_n_c_t_i_o_n specifies which action to take when _k_e_y is pressed. For a + complete list of functions, see the ffuunnccttiioonnss. The special function + noop unbinds the specified key sequence. - 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. - - 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. - - 2.3. File Browser - - 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. - - 2.4. Sidebar - - 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. - - 2.5. Help - - 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). - - 2.6. Compose Menu - - 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. - - 2.7. Alias Menu - - 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. - - 2.8. Attachment Menu - - 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. - - 2.9. Key Menu +6. Defining aliases for character sets - FIXME + Usage: cchhaarrsseett--hhooookk_a_l_i_a_s_c_h_a_r_s_e_t -3. Moving Around in Menus + Usage: iiccoonnvv--hhooookk_c_h_a_r_s_e_t_l_o_c_a_l_-_c_h_a_r_s_e_t - Information is presented in menus, very similar to ELM. Here is a - tableshowing the common keys used to navigate menus in Mutt-ng. + The cchhaarrsseett--hhooookk 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. - Table 2.1. Most commonly used movement bindings + The iiccoonnvv--hhooookk 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. - Key Function Description - j or Down move to the next entry - k or Up move to the previous entry - z or PageDn go to the next page - Z or PageUp go to the previous page - = or Home jump to the first entry - * or End jump to the last entry - q exit the current menu - ? list all key bindings for the current menu +7. Setting variables based upon mailbox -4. Editing Input Fields + Usage: ffoollddeerr--hhooookk [!]_r_e_g_e_x_p_c_o_m_m_a_n_d - 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. + It is often desirable to change settings based on which mailbox you + are reading. The ffoollddeerr--hhooookk command provides a method by which you + can execute any configuration command. _r_e_g_e_x_p is a regular expression + specifying in which mailboxes to execute _c_o_m_m_a_n_d before loading. If a + mailbox matches multiple ffoollddeerr--hhooookk's, they are executed in the order + given in the muttrc. - Table 2.2. Line Editor Functions + _N_o_t_e_: if you use the ``!'' shortcut for $$ssppoooollffiillee at the beginning of + the pattern, you must place it inside of double or single quotes in + order to distinguish it from the logical _n_o_t operator for the + expression. - Key Function Description - C-A or Home move to the start of the line - C-B or Left move back one char - E-B move back one word - C-D or Delete delete the char under the cursor - C-E or End move to the end of the line - C-F or Right move forward one char - E-F move forward one word - Tab complete filename or alias - C-T complete address with query - C-K delete to the end of the line - E-d delete to the end of the word - C-W kill the word in front of the cursor - C-U delete entire line - C-V quote the next typed key - Up recall previous string from history - Down recall next string from history - BackSpace kill the char in front of the cursor - E-u convert word to upper case - E-l convert word to lower case - E-c capitalize the word - C-G abort - Return finish editing + Note that the settings are _n_o_t restored when you leave the mailbox. + For example, a command action to perform is to change the sorting + methodbased upon the mailbox being read: - 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 +folder-hook mutt set sort=threads - bind editor backspace + However, the sorting method is not restored to its previous value when + reading a different mailbox. To specify a _d_e_f_a_u_l_t command, use the + pattern ``.'': -5. Reading Mail - The Index and Pager +folder-hook . set sort=date-sent - Similar to many other mail clients, there are two modes in which mail - isread 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.'' +8. Keyboard macros - The next few sections describe the functions provided in each of these - modes. + Usage: macro_m_e_n_u_ _k_e_y_ _s_e_q_u_e_n_c_e_ _[_d_e_s_c_r_i_p_t_i_o_n_] - 5.1. The Message Index + Macros are useful when you would like a single key to perform a series + of actions. When you press _k_e_y in menu _m_e_n_u ,Mutt-ng will behave as if + you had typed _s_e_q_u_e_n_c_e. So if you have a common sequence of commands + you type, you can create a macro to execute those commands with a + singlekey. - Table 2.3. Most commonly used Index Bindings + _m_e_n_u is the mmaappss 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 thecommas separating + them. - Key Function Description - c change to a different mailbox - E-c change to a folder in read-only mode - C copy the current message to another mailbox - E-C decode a message and copy it to a folder - E-s decode a message and save it to a folder - D delete messages matching a pattern - d delete the current message - F mark as important - l show messages matching a pattern - N mark message as new - o change the current sort method - O reverse sort the mailbox - q save changes and exit - s save-message - T tag messages matching a pattern - t toggle the tag on a message - E-t toggle tag on entire message thread - U undelete messages matching a pattern - u undelete-message - v view-attachments - x abort changes and exit - Return display-message - Tab jump to the next new or unread message - @ show the author's full e-mail address - $ save changes to mailbox - / search - E-/ search-reverse - C-L clear and redraw the screen - C-T untag messages matching a pattern + _k_e_y and _s_e_q_u_e_n_c_e are expanded by the same rules as the bbiinndd. There are + some additions however. The first is that control characters in + _s_e_q_u_e_n_c_e can also be specified as ^x. In order to get a caret (`^'') + you need to specify it twice. Secondly, to specify a certain key such + as _u_p or to invoke a function directly, you can use the format _<_k_e_y + _n_a_m_e_> and _<_f_u_n_c_t_i_o_n_ _n_a_m_e_> .For a listing of key names see the section + on bbiinndd. Functions are listed in the ffuunnccttiioonnss. - 5.1.1. Status Flags + The advantage with using function names directly is that the macros + willwork regardless of the current key bindings, so they are not + dependent on the user having particular key definitions. This makes + them more robustand portable, and also facilitates defining of macros + in files used by more than one user (eg. the system Muttngrc). - 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: + Optionally you can specify a descriptive text after _s_e_q_u_e_n_c_e, which is + shown in the help screens. - D + _N_o_t_e_: Macro definitions (if any) listed in the help screen(s), are + silently truncated at the screen width, and are not wrapped. - message is deleted (is marked for deletion) +9. Using color and mono video attributes - d + Usage: color_o_b_j_e_c_t_ _f_o_r_e_g_r_o_u_n_d_ _b_a_c_k_g_r_o_u_n_d_ _[_r_e_g_e_x_p_] + + Usage: color_i_n_d_e_x_ _f_o_r_e_g_r_o_u_n_d_ _p_a_t_t_e_r_n + + Usage: uncolor_i_n_d_e_x_ _p_a_t_t_e_r_n_ _[_p_a_t_t_e_r_n_ _._._._] + + 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_n_d a + background color (it is not possible to only specify one or the + other). + + _o_b_j_e_c_t can be one of: + + * attachment + * body (match _r_e_g_e_x_p in the body of messages) + * bold (highlighting bold patterns in the body of messages) + * error (error messages printed by Mutt-ng) + * header (match _r_e_g_e_x_p in the message header) + * hdrdefault (default color of the message header in the pager) + * index (match _p_a_t_t_e_r_n in the message index) + * indicator (arrow or bar used to indicate the current item in a + menu) + * markers (the ``+'' markers at the beginning of wrapped lines in + the pager) + * message (informational messages) + * normal + * quoted (text matching $$qquuoottee__rreeggeexxpp in the body of a message) + * quoted1, quoted2, ..., quoted_N (higher levels of quoting) + * search (highlighting of words in the pager) + * signature + * status (mode lines used to display info about the mailbox or + message) + * tilde (the ``~'' used to pad blank lines in the pager) + * tree (thread tree drawn in the message index and attachment menu) + * underline (highlighting underlined patterns in the body of + messages) + + _f_o_r_e_g_r_o_u_n_d and _b_a_c_k_g_r_o_u_n_d can be one of the following: + + * white + * black + * green + * magenta + * blue + * cyan + * yellow + * red + * default + * color_x + + _f_o_r_e_g_r_o_u_n_d can optionally be prefixed with the keyword bright to make + the foreground color boldfaced (e.g., brightred). + + If your terminal supports it, the special keyword _d_e_f_a_u_l_t can be used + as a transparent color. The value _b_r_i_g_h_t_d_e_f_a_u_l_t is also valid. If + Mutt-ng is linked against the _S_-_L_a_n_g library, you also need to set the + $COLORFGBG environment variable to the default colors of your terminal + for this to work; for example (for Bourne-like shells): + +set COLORFGBG="green;black" +export COLORFGBG + + _N_o_t_e_: The _S_-_L_a_n_g library requires you to use the _l_i_g_h_t_g_r_a_y and _b_r_o_w_n + keywords instead of _w_h_i_t_e and _y_e_l_l_o_w when setting this variable. + + _N_o_t_e_: The uncolor command can be applied to the index object only. It + removes entries from the list. You _m_u_s_t specify the same pattern + specified in the color command for it to be removed.

Format = Flowed - Furthermore, the following flags reflect who the message is addressed to. - They can be customized with the $to_chars variable. +12.1. Introduction - + + 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. - message is to you and you only + For introductory information on format=flowed messages, see + <>. - T +12.2. Receiving: Display Setup - message is to you, but also to or cc'ed to others + 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: - C +set wrapmargin = 10 - message is cc'ed to you + The code above makes the line break 10 columns before the right side + of the terminal. - F + If your terminal is so wide that the lines are embarrassingly long, + you can also set a maximum line length: - message is from you +set max_line_length = 120 - L + The example above will give you lines not longer than 120 characters. - message is sent to a subscribed mailing list + When you view at format=flowed messages, you will often see the + quoting hierarchy like in the following example: - 5.2. The Pager +>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. - 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. + 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: - Table 2.4. Most commonly used Pager Bindings +set stuff_quoted - Key Function Description - 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) - E-/ 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 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). - - Also, the internal pager supports a couple other advanced features. For - one, it will accept and translate the ``standard'' nroff sequences forbold - and underline. These sequences are a series of either the letter, - backspace (C-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. - - 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 (see table below for possible values for Ps). - - Table 2.5. ANSI Escape Sequences + This will lead to a nicer result that is easier to read: - Value Attribute - 0 All Attributes Off - 1 Bold on - 4 Underline on - 5 Blink on - 7 Reverse video on - 3x Foreground color is x (see table below) - 4x Background color is x (see table below) +> 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. - Table 2.6. ANSI Colors +12.3. Sending - Number Color - 0 black - 1 red - 2 green - 3 yellow - 4 blue - 5 magenta - 6 cyan - 7 white + If you want mutt-ng to send emails with format=flowed set, you need to + explicitly set it: - Mutt-ng uses these attributes for handling text/enriched messages, and - they can also be used by an external auto_view 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. - - 5.3. Threaded Mode - - When the mailbox is sorted by threads ,there are a few additional - functions available in the index and pager modes. - - Table 2.7. Most commonly used thread-related bindings - - Key Function Description - C-D delete all messages in the current thread - C-U undelete all messages in the current thread - C-N jump to the start of the next thread - C-P jump to the start of the previous thread - C-R mark the current thread as read - E-d delete all messages in the current subthread - E-u undelete all messages in the current subthread - E-n jump to the start of the next subthread - E-p jump to the start of the previous subthread - E-r mark the current subthread as read - E-t toggle the tag on the current thread - E-v toggle collapse for the current thread - E-V toggle collapse for all threads - P jump to parent message in thread - - 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 onthe 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. +set text_flowed - See also the $strict_threads variable. + Additionally, you have to use an editor which supports writing + format=flowed-conforming emails. For vim(1), this is done by adding w + to the formatoptions (see :h formatoptions and :h fo-table) when + writing emails. + + Also note that _f_o_r_m_a_t_=_f_l_o_w_e_d 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 (RRffCC  33667766) as it does not space-stuff lines + starting with: + + * > This is _n_o_t the quote character but a right angle used for other + reasons - 5.4. Miscellaneous Functions + Please make sure that you manually prepend a space to each of them. - (default: a) +12.4. Additional Notes - 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. + For completeness, the $$ddeelleettee__ssppaaccee variable provides the mechanism to + generate a DelSp=yes parameter on _o_u_t_g_o_i_n_g 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 _w_i_t_h_o_u_t 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. - (default: E-P) +13. Mailing lists - 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 function's effect. + Usage: lists_r_e_g_e_x_p_ _[_r_e_g_e_x_p_ _._._._] - (default: h) + Usage: unlists_r_e_g_e_x_p_ _[_r_e_g_e_x_p_ _._._._] - Toggles the weeding of message header fields specified by ignore commands. + Usage: subscribe_r_e_g_e_x_p_ _[_r_e_g_e_x_p_ _._._._] - (default: e) + Usage: unsubscribe_r_e_g_e_x_p_ _[_r_e_g_e_x_p_ _._._._] - 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. + Mutt-ng has a few nice features for uussiinngg--lliissttss. 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 lliisstt--rreeppllyy 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 + $$ffoolllloowwuupp__ttoo configuration variable. + + 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''. + + 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. - (default: ) (default: C-E on the attachment menu, and in the - pager and index menus; C-T on the compose menu) + 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 _m_u_t_t_-_u_s_e_r_s_@_m_u_t_t_._o_r_g. 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 + _m_u_t_t_-_u_s_e_r_s_@_e_x_a_m_p_l_e_._c_o_m, you could use ``lists mutt-users@mutt\\.org'' + or ``subscribe mutt-users@mutt\\.org'' to match only mail from the + actual list. + + The ``unlists'' command is used to remove a token from the list of + known and subscribed mailing-lists. Use ``unlists *'' to remove all + tokens. + + To remove a mailing list from the list of subscribed mailing lists, + but keep it on the list of known mailing lists, use ``unsubscribe''. - 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. +14. Using Multiple spool mailboxes - 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. + Usage: mmbbooxx--hhooookk [!]_p_a_t_t_e_r_n_m_a_i_l_b_o_x - (default: :) + This command is used to move read messages from a specified mailbox to + adifferent mailbox automatically when you quit or change folders. + _p_a_t_t_e_r_n is a regular expression specifying the mailbox to treat as a + ``spool'' mailbox and _m_a_i_l_b_o_x specifies where mail should be saved + when read. - 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. + Unlike some of the other _h_o_o_k commands, only the _f_i_r_s_t matching + pattern is used (it is not possible to save read mail in more than a + single mailbox). - (default: C-K) +15. Defining mailboxes which receive mail - This command extracts PGP public keys from the current or tagged - message(s) and adds them to your PGP public key ring. + Usage: mailboxes_[_!_]_f_i_l_e_n_a_m_e_ _[_f_i_l_e_n_a_m_e_ _._._._ _] - (default: C-F) + Usage: unmailboxes_[_!_]_f_i_l_e_n_a_m_e_ _[_f_i_l_e_n_a_m_e_ _._._._ _] - This command wipes the passphrase(s) from memory. It is useful, if you - misspelled the passphrase. + 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. - (default: L) + When changing folders, pressing _s_p_a_c_e will cycle through folders with + new mail. - 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. + 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. - (default: ) + The ``unmailboxes'' command is used to remove a token from the list of + folders which receive mail. Use ``unmailboxes *'' to remove all + tokens. + + _N_o_t_e_: 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. + + _N_o_t_e_: the filenames in the mailboxes command are resolved when the + command is executed, so if these names contain sshhoorrttccuuttss (such as + ``='' and ``!''), any variable definition that affect these characters + (like $$ffoollddeerr and $$ssppoooollffiillee) should be executed before the mailboxes + command. - Asks for an external Unix command and pipes the current or tagged - message(s) to it. The variables $pipe_decode, $pipe_split, $pipe_decode - and $wait_key control the exact behavior of this function. +16. User defined headers - (default: E-e) + Usage: my_hdr_s_t_r_i_n_g - 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. + Usage: unmy_hdr_f_i_e_l_d_ _[_f_i_e_l_d_ _._._._] - 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. + The ``my_hdr'' command allows you to create your own header fields + which will be added to every message you send. - (default: !) + For example, if you would like to add an ``Organization:'' header + field to all of your outgoing messages, you can put the command - 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. +my_hdr Organization: A Really Big Company, Anytown, USA - (default: T) + in your .muttrc. - The pager uses the $quote_regexp variable to detect quoted text when - displaying the body of the message. This function toggles the displayof - 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. + _N_o_t_e_: space characters are _n_o_t allowed between the keyword and the + colon (``:''). The standard for electronic mail (RRffCC  882222) says that + space is illegal there, so Mutt-ng enforces the rule. - (default: S) + If you would like to add a header field to a single message, you + should either set the $$eeddiitt__hheeaaddeerrss variable, or use the _e_d_i_t_-_h_e_a_d_e_r_s + function (default: ``E'') in the send-menu so that you can edit the + header of your message along with the body. - This function will go to the next line of non-quoted text which come after - a line of quoted text in the internal pager. + 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: -6. Sending Mail +unmy_hdr to cc - The following bindings are available in the index for sending messages. +17.

These items are discussed in greater detail in the next - chapter forwarding-mail. + With this command, you can specify an order in which mutt will attempt + to present headers to you when viewing messages. - 6.1. Composing new messages + ``unhdr_order *'' will clear all previous headers from the order list, + thus removing the header order effects set by the system-wide startup + file. - 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: +hdr_order From Date: From: To: Cc: Subject: - To: +18. Specify default save filename - 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. + Usage: ssaavvee--hhooookk [!]_p_a_t_t_e_r_n_f_i_l_e_n_a_m_e - The editor that is called is selected in the following way: you can e.g. - set it in the mutt-ng configuration: + This command is used to override the default filename used when saving + messages. _f_i_l_e_n_a_m_e will be used as the default filename if the message + is _F_r_o_m_: an address matching _r_e_g_e_x_p or if you are the author and the + message is addressed _t_o_: something matching _r_e_g_e_x_p . - set editor = "vim +/^$/ -c ':set tw=72'" - set editor = "nano" - set editor = "emacs" + See ppaatttteerrnn--hhooookk for information on the exact format of _p_a_t_t_e_r_n. - 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(1) 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 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 - 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 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.

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. + Usage: sseenndd22--hhooookk [!]_p_a_t_t_e_r_n_c_o_m_m_a_n_d - 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. + These commands can be used to execute arbitrary configuration commands + based upon recipients of the message. _p_a_t_t_e_r_n is a regular expression + matching the desired address. _c_o_m_m_a_n_d is executed when _r_e_g_e_x_p matches + recipients of the message. - 6.2.2. Group Replies + rreeppllyy--hhooookk is matched against the message you are _r_e_p_l_y_i_n_g _t_o, instead + of the message you are _s_e_n_d_i_n_g .  sseenndd--hhooookk is matched against all + messages, both _n_e_w and _r_e_p_l_i_e_s ._N_o_t_e_:rreeppllyy--hhooookks are matched _b_e_f_o_r_e + the sseenndd--hhooookk, _r_e_g_a_r_d_l_e_s_s of the order specified in the users's + configuration 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:" - recipients. The group reply functionalityensures 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. + sseenndd22--hhooookk is matched every time a message is changed, either by + editing it, or by using the compose menu to change its recipients or + subject. sseenndd22--hhooookk is executed after sseenndd--hhooookk ,and can, e.g., be + used to set parameters such as the $$sseennddmmaaiill variable depending on the + message's sender address. - 6.2.3. List Replies + For each type of sseenndd--hhooookk or rreeppllyy--hhooookk, when multiple matches occur, + commands are executed in the order they are specified in the muttrc + (for that type of hook). - When you use mailing lists, it's generally better to send your reply to a - message only to the list instead of the list and the original author. To - make this easy to use, mutt-ng features list replies. + See ppaatttteerrnn--hhooookk for information on the exact format of _p_a_t_t_e_r_n. - To do a list reply, simply press L. If the email contains a - Mail-Followup-To: header, its value will be used as reply address. - Otherwise, mutt-ng searches through all mail addresses in the original - message and tries to match them a list of regular expressions which can be - specified using the lists command. If any of the regular expression - matches, a mailing list address has been found, and it will be used as - reply address. + Example: send-hook mutt "set mime_forward signature=''" - lists linuxevent@luga\.at vuln-dev@ mutt-ng-users@ + Another typical use for this command is to change the values of the + $$aattttrriibbuuttiioonn, $$ssiiggnnaattuurree and $$llooccaallee variables in order to change the + language of the attributions and signatures based upon the recipients. - 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. + _N_o_t_e_: the sseenndd--hhooookk'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 sseenndd--hhooookk 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 sseenndd--hhooookk. - 6.3. Editing the message header +22. Change settings before formatting a message - When editing the header of your outgoing message, there are a couple of - special features available. + Usage: mmeessssaaggee--hhooookk [!]_p_a_t_t_e_r_n_c_o_m_m_a_n_d - 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. + This command can be used to execute arbitrary configuration commands + before viewing or formatting a message based upon information about + the message. _c_o_m_m_a_n_d is executed if the _p_a_t_t_e_r_n matches the message to + be displayed. When multiple matches occur, commands are executed in + the order they are specified in the muttrc. - You can also attach files to your message by specifying + See ppaatttteerrnn--hhooookk for information on the exact format of _p_a_t_t_e_r_n. - Attach: filename [description] + Example: +message-hook ~A 'set pager=builtin' +message-hook '~f freshmeat-news' 'set pager="less \"+/^ subject:.*\""' - where filename is the file to attach and description is an optional string - to use as the description of the attached file. +23. Choosing the cryptographic key of the recipient - 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. + Usage: ccrryypptt--hhooookk_p_a_t_t_e_r_n_k_e_y_i_d - Also see the $edit_headers and $editor_headers variables + 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 wouldnormally use. The ccrryypptt--hhooookk 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. - 6.4. Using Mutt-ng with PGP + 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 you want to use PGP, you can specify +24. Adding key sequences to the keyboard buffer - Pgp: [E | S | S id] + Usage: push_s_t_r_i_n_g - ``E'' encrypts, ``S'' signs and ``S'' signs with the given key, - setting $pgp_sign_as permanently. + 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 mmaaccrroo command. You may use it to automatically + run a sequence of commands at startup, or when entering certain + folders. For example, the following command will automatically + collapse all threads when entering a folder: +folder-hook . 'push ' - 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. +25. Executing functions - 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 C-G. When you do so, mutt will return to the compose - screen. + Usage: exec_f_u_n_c_t_i_o_n_ _[_f_u_n_c_t_i_o_n_ _._._._ _] - Once you have successfully finished the key selection, the message will be - encrypted using the selected public keys, and sent out. + This command can be used to execute any function. Functions are listed + in the ffuunnccttiioonnss. ``exec function'' is equivalent to ``push + ''. - 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. +26. Message Scoring - The flags sequence (%f) will expand to one of the following flags: + Usage: score_p_a_t_t_e_r_n_ _v_a_l_u_e - Table 2.10. PGP Key Menu Flags + Usage: unscore_p_a_t_t_e_r_n_ _[_p_a_t_t_e_r_n_ _._._._ _] - Flag Description - 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. + 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''. - The capabilities field (%c) expands to a two-character - sequencerepresenting 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. + 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. - 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. +score "~f nion@muttng\.org" 50 +score "~f @sco\.com" -100 - 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. + 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: - 6.5. Sending anonymous messages via mixmaster +score "~f santaclaus@northpole\.int" =666 - 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. + What is important to note is that negative score values will be + rounded up to 0. - 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. + To make scoring actually useful, the score must be applied in some + way. That's what the _s_c_o_r_e_ _t_h_r_e_s_h_o_l_d_s are for. Currently, there are + three score thresholds: - 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. + * 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. - 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. - - 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. + These three thresholds can be set via the variables + $$ssccoorree__tthhrreesshhoolldd__rreeaadd, $$ssccoorree__tthhrreesshhoolldd__ffllaagg and + $$ssccoorree__tthhrreesshhoolldd__ddeelleettee. -7. Forwarding and Bouncing Mail + By default, $$ssccoorree__tthhrreesshhoolldd__rreeaadd and $$ssccoorree__tthhrreesshhoolldd__ddeelleettee are set + to -1, which means that in the default threshold configuration no + message will ever get marked as read or deleted. - Often, it is necessary to forward mails to other people. Therefore, - mutt-ng supports forwarding messages in two different ways. + Scoring gets especially interesting when combined with the color + command and the ~n pattern: - 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: +color index black yellow "~n 10-" +color index red yellow "~n 100-" - ----- Forwarded message from Lucas User ----- + 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. - From: Lucas User - Date: Thu, 02 Dec 2004 03:08:34 +0100 - To: Michael Random - Subject: Re: blackmail +27. Spam detection - Pay me EUR 50,000.- cash or your favorite stuffed animal will die - a horrible death. + Usage: spam_p_a_t_t_e_r_n_ _f_o_r_m_a_t - ----- End forwarded message ----- + Usage: nospam_p_a_t_t_e_r_n - 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. + Mutt-ng has generalized support for external spam-scoring filters. By + defining your spam patterns with the spam and nospam commands, you can + _l_i_m_i_t, _s_e_a_r_c_h, and _s_o_r_t 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 + $$iinnddeexx__ffoorrmmaatt variable. (Tip: try %?H?[%H] ? to display spam tags only + when they are defined for a given message.) - 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. + Your first step is to define your external filter's spam patterns + using the spam command. _p_a_t_t_e_r_n 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 _f_o_r_m_a_t parameter. _f_o_r_m_a_t can be any static text, but + it also can include back-references from the _p_a_t_t_e_r_n 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. + + 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 _f_o_r_m_a_t strings joined together, with the + value of $spam_separator separating them. - 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. + 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=", " -8. Postponing Mail + 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 + read90+/DCC-Fuz2, 97/PM. (The four characters before ``=many'' in a + DCC report indicate the checksum used -- in this case, ``Fuz2''.) - 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. + If the $spam_separator variable is unset, then each spam pattern match + supersedes the previous one. Instead of getting joined _f_o_r_m_a_t strings, + you'll get only the last one to match. - 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. + 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 _s_e_a_r_c_h and _l_i_m_i_t + functions. And it's what sorting by spam attribute will use as a sort + key. + + 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. + + Generally, when you sort by spam tag, mutt will sort _l_e_x_i_c_a_l_l_y -- 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 _a_n_y 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 lowerpriority 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. + + 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 amore + precise pattern under a nospam command. + + If the _p_a_t_t_e_r_n given to nospam is exactly the same as the _p_a_t_t_e_r_n 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 + _p_a_t_t_e_r_n for a spam command matches an entry on the nospam list, that + nospam entry will be removed. If the _p_a_t_t_e_r_n for nospam is ``*'', _a_l_l + _e_n_t_r_i_e_s_ _o_n_ _b_o_t_h_ _l_i_s_t_s will be removed. This might be the default + action if you use spam and nospam in conjunction with a ffoollddeerr--hhooookk. + + 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" - 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. +28.

Locations of Configuration Files +ifdef pager 'set pager_index_lines = 10' - 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.

Advanced Usage - Single quotes (') and double quotes (") can be used to quote strings which - contain spaces or other special characters.

EEnnccrryypptteedd  ffoollddeerrss - 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: +1. Regular Expressions - my_hdr X-Operating-System: `uname -a` + All string patterns in Mutt-ng including those in more complex + ppaatttteerrnnss 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. + + 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: ``\\''. + + 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. + + 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 mmuuttttrrcc--ssyynnttaaxx for more information on " and ' delimiter + processing. To match a literal " or ' you must preface it with \ + (backslash). - 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. + 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. - 3.2. Environment Variables + The period ``.'' matches any single character. The caret ``^'' andthe + dollar sign ``$'' are metacharacters that respectively match the empty + string at the beginning and end of a line. - UNIX environments can be accessed like the way it is done in shells like - sh and bash: Prepend the name of the environment by a ``$'' sign. For - example, + 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_o_t in the list. For example, the + regular expression _]_0_1_2_3_4_5_6_7_8_9_] 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. - set record=+sent_on_$HOSTNAME + 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: - sets the $record variable to the string +sent_on_ and appends the value of - the evironment variable $HOSTNAME. + [:alnum:] + Alphanumeric characters. - Note: There will be no warning if an environment variable is not defined. - The result will of the expansion will then be empty. + [:alpha:] + Alphabetic characters. - 3.3. Configuration Variables + [:blank:] + Space or tab characters. - As for environment variables, the values of all configuration variables as - string can be used in the same way, too. For example, + [:cntrl:] + Control characters. - set imap_home_namespace = $folder + [:digit:] + Numeric characters. - would set the value of $imap_home_namespace to the value to which $folder - is currently set to. + [:graph:] + Characters that are both printable and visible. (A space is + printable, but not visible, while an ``a'' is both.) - Note: There're no logical links established in such cases so that the the - value for $imap_home_namespace won't change even if $folder gets changed. + [:lower:] + Lower-case alphabetic characters. - Note: There will be no warning if a configuration variable is not defined - or is empty. The result will of the expansion will then be empty. + [:print:] + Printable characters (characters that are not control + characters.) - 3.4. Self-Defined Variables + [:punct:] + Punctuation characters (characters that are not letter, digits, + control characters, or space characters). - Mutt-ng flexibly allows users to define their own variables. To avoid - conflicts with the standard set and to prevent misleading error messages, - there's a reserved namespace for them: all user-defined variables must be - prefixed with user_ and can be used just like any ordinary configuration - or environment variable. + [:space:] + Space characters (such as space, tab and formfeed, to name a + few). - For example, to view the manual, users can either define two macros like - the following + [:upper:] + Upper-case alphabetic characters. - macro generic "!less -r /path/to/manual" "Show manual" - macro pager "!less -r /path/to/manual" "Show manual" + [:xdigit:] + Characters that are hexadecimal digits. - for generic, pager and index .The alternative is to define a custom - variable like so: + A character class is only valid in a regular expression inside the + brackets of a character list. Note that the brackets in these class + names are part of the symbolic names, and must be included in addition + to the brackets delimiting the bracket list. For example, _[_[_:_d_i_g_i_t_:_]_] + is equivalent to _[_0_-_9_]. - set user_manualcmd = "!less -r /path/to_manual" - macro generic "$user_manualcmd" "Show manual" - macro pager "$user_manualcmd" "Show manual" - macro index "$user_manualcmd" "Show manual" + Two additional special sequences can appear in character lists. These + apply to non-ASCII character sets, which can have single symbols + (calledcollating elements) that are represented with more than one + character, as well as several characters that are equivalent for + collating or sorting purposes: - to re-use the command sequence as in: + Collating Symbols + A collating symbol is a multi-character collating element + enclosed in ``[.'' and ``.]''. For example, if ``ch'' is a + collating element, then _[_[_._c_h_._]_] is a regexp that matches this + collating element, while _[_c_h_] is a regexp that matches either + ``c'' or ``h''. - macro index "$user_manualcmd | grep '\^[ ]\\+~. '" "Show Patterns" + 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''. - 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. + A regular expression matching a single character may be followed by + one of several repetition operators: - 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. + ? + The preceding item is optional and matched at most once. - The complete removal is done via the unset keyword. + * + The preceding item will be matched zero or more times. - After the following sequence: + + + The preceding item will be matched one or more times. - set user_foo = 42 - set user_foo = 666 + {n} + The preceding item is matched exactly _n times. - the variable $user_foo has a current value of 666 and an initial of 42. - The query + {n,} + The preceding item is matched _n or more times. - set ?user_foo + {,m} + The preceding item is matched at most _m times. - will show 666. After doing the reset via + {n,m} + The preceding item is matched at least _n times, but no more + than _m times. - reset user_foo + Two regular expressions may be concatenated; the resulting regular + expression matches any string formed by concatenating two substrings + that respectively match the concatenated subexpressions. - a following query will give 42 as the result. After unsetting it via + Two regular expressions may be joined by the infix operator ``|''; the + resulting regular expression matches any string matching either + subexpression. - unset user_foo + 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. - any query or operation (except the noted expansion within other - statements) will lead to an error message. + _N_o_t_e_: If you compile Mutt-ng with the GNU _r_x package, the following + operators may also be used in regular expressions: - 3.5. Pre-Defined Variables + \\y + Matches the empty string at either the beginning or the end of + a word. - 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. + \\B + Matches the empty string within a word. - 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: + \\< + Matches the empty string at the beginning of a word. - $ muttng -Q muttng_docdir + \\> + Matches the empty string at the end of a word. - 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: + \\w + Matches any word-constituent character (letter, digit, or + underscore). - set user_manualcmd = '!less -r /path/to_manual' + \\W + Matches any character that is not word-constituent. - to: + \\` + Matches the empty string at the beginning of a buffer (string). - set user_manualcmd = "!less -r $muttng_docdir/manual.txt" + \\' + Matches the empty string at the end of a buffer. - which works everywhere if a manual is installed. + 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. - 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. +2. Patterns - For example, the statement + 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 ppaatttteerrnnss in the Reference chapter. - folder-hook . "set user_current_folder = $muttng_folder_name" + It must be noted that in this table, EXPR is a regular expression. For + ranges, the forms <[MAX], >>[MIN], [MIN]- and -[MAX] are also + possible. - will be already be translated to the following when reading the startup - files: +2.1. Complex Patterns - folder-hook . "set user_current_folder = some_folder" + 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: - with some_folder being the name of the first folder muttng opens. On the - contrary, +~s 'SPAM' ~U - folder-hook . 'set user_current_folder = $muttng_folder_name' + The pattern above matches all messages that contain ``SPAM'' in the + subject and are unread. - will be executed at runtime because of the single quotes so that - user_current_folder will always have the value of the currently opened - folder. + To logical OR patterns, simply use the | operator. This one especially + useful when using local groups: - A more practical example is: +~f ("nion@muttng\.org"|"ak@muttng\.org"|"pdmef@muttng\.org") +(~b mutt-ng|~s Mutt-ng) +!~x '@synflood\.at' - folder-hook . 'source ~/.mutt/score-$muttng_folder_name' + 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. - which can be used to source files containing score commands depending on - the folder the user enters. +2.2. Patterns and Dates - 3.6. Type Conversions + 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 _a_f_t_e_r Juni + 1st, 2005. - 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 + 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 + + 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). -4. Defining/Using aliases + 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: - Usage: aliaskey address [, address,...] +~d >2w # messages older than two weeks +~d <3d # messages newer than 3 days +~d =1m # messages that are exactly one month old - 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. +3. Format Strings - 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 (``,''). +3.1. Introduction - To remove an alias or aliases (``*'' means all aliases): + The so called _F_o_r_m_a_t_ _S_t_r_i_n_g_s offer great flexibility when configuring + mutt-ng. In short, they describe what items to print out how in menus + and status messages. - Usage: unalias[* | key ... ] + 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 _e_x_p_a_n_d_o. - alias muttdude me@cs.hmc.edu (Michael Elkins) - alias theguys manny, moe, jack + 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: - 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. + * the current hostname + * the current mutt-ng version number - On the other hand, the 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. - - For example: - - source /usr/local/share/Mutt-ng.aliases - source ~/.mail_aliases - set alias_file=~/.mail_aliases + The setting for the status bar of the index is controlled via the + $$ssttaattuuss__ffoorrmmaatt 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: - To use aliases, you merely use the alias at any place in mutt where - muttprompts 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 - $editor_headers variable set. +set status_format = "%v on %h: ..." - 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. + 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: - 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. +Mutt-ng 1.5.9i on mailhost: ... -5. Changing the default key bindings + In the index, there're more useful information one could want to see: - Usage: bindmap key function + * which mailbox is open + * how man new, flagged or postponed messages + * ... - This command allows you to change the default key bindings (operation - invoked when pressing a key). + To include the mailbox' name is as easy as: - map specifies in which menu the binding belongs. Multiple maps may be - specified by separating them with commas (no additional whitespace - isallowed). The currently defined maps are: +set status_format = "%v on %h: %B: ... - generic + When the currently opened mailbox is Inbox, this will be expanded to: - 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.

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. - The alias menu is the list of your personal aliases as defined in - your muttrc.

The basic syntax is: - The browser is used for both browsing the local directory - structure, and for listing all of your incoming mailboxes. +%??? - editor + which tells mutt-ng to only look at if the value + of the %?&? - The index is the list of messages contained in a mailbox. + Using this we can make mutt-ng to do the following: - compose + * 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 - The compose menu is the screen used when sending a new message. + The corresponding configuration is: - pager +set status_format = "%v on %h: %B: %?n?%n new messages&no new messages? ... - The pager is the mode used to display message/attachment data, and - help listings. + This doubles the use of the ``new messages'' string because it'll get + always printed. Thus, it can be shortened to: - pgp +set status_format = "%v on %h: %B: %?n?%n&no? new messages ... - The pgp menu is used to select the OpenPGP keys used for - encrypting outgoing messages. + 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. - postpone +3.3. Modifications and Padding - The postpone menu is similar to the index menu, except is used - when recalling a message the user was composing, but saved until - later. + Besides the information given so far, there're even more features of + format strings: - 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?). + * When specifying %_ instead of just %, mutt-ng will + convert all characters in the expansion of to lowercase. + * When specifying %: instead of just %, mutt-ng will + convert all dots in the expansion of to underscores (_). - In addition, key may consist of: + Also, there's a feature called _P_a_d_d_i_n_g supplied by the following two + expandos: %|X and %>X . - Table 3.1. Alternative Key Names + %|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: - Sequence Description - \t tab - tab - backtab / shift-tab - \r carriage return - \n newline - \e escape - escape - up arrow - down arrow - left arrow - right arrow - Page Up - Page Down - Backspace - Delete - Insert - Enter - Return - Home - End - Space bar - function key 1 - function key 10 +set status_format = "%v on %h: %B: %?n?%n&no? new messages %|-" - key does not need to be enclosed in quotes unless it contains a space (`` - ''). + %>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 %>): - function specifies which action to take when key is pressed.

Defining aliases for character sets +4. Using Tags - Usage: charset-hookaliascharset + 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 + ppaatttteerrnnss for Mutt-ng's pattern matching syntax. + + 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 _n_e_x_t operation + will be applied to all tagged messages if that operation can be used + in that manner. If the $$aauuttoo__ttaagg variable is set, the next operation + applies to the tagged messages automatically, without requiring the + ``tag-prefix''. + + In mmaaccrroo or ppuusshh 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 asnormal. - Usage: iconv-hookcharsetlocal-charset +5. Using Hooks - 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. + A _h_o_o_k 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 _h_o_o_k consists of a rreeggeexxpp or ppaatttteerrnnss along with a + configuration option/command. See + * ffoollddeerr--hhooookk + * sseenndd--hhooookk + * mmeessssaaggee--hhooookk + * ssaavvee--hhooookk + * mmbbooxx--hhooookk + * ffcccc--hhooookk + * ffcccc--ssaavvee--hhooookk + + for specific details on each type of _h_o_o_k available. + + _N_o_t_e_: 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 + sseenndd--hhooookk and the my_hdr directive: + +send-hook . 'unmy_hdr From:' +send-hook '~C ^b@b\.b$' my-hdr from: c@c.c + +5.1. Message Matching in Hooks + + Hooks that act upon messages (  sseenndd--hhooookk, ssaavvee--hhooookk, ffcccc--hhooookk, + mmeessssaaggee--hhooookk )are evaluated in a slightly different manner. For the + other types of hooks, a rreeggeexxpp 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. + + Mutt-ng allows the use of the ppaatttteerrnnss language for matching messages + in hook commands. This works in exactly the same way as it would when + _l_i_m_i_t_i_n_g or_s_e_a_r_c_h_i_n_g 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.). + + 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 ' + + which would execute the given command when sending mail to + _m_e_@_c_s_._h_m_c_._e_d_u. + + However, it is not required that you write the pattern to match using + the full searching language. You can still specify a simple _r_e_g_u_l_a_r + _e_x_p_r_e_s_s_i_o_n like the other hooks, in which case Mutt-ng will translate + your pattern into the full language, using the translation specified + by the ddeeffaauulltt--hhooookk variable. The pattern is translated at the time + the hook is declared, so the value of ddeeffaauulltt--hhooookk that is in effect + at that time will be used. - 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. +6. Using the sidebar -7. Setting variables based upon mailbox + 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 - Usage: folder-hook [!]regexpcommand + If you want to specify the mailboxes you can do so with: +set mbox='=INBOX' +mailboxes INBOX \ +MBOX1 \ +MBOX2 \ +... - 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. + You can also specify the colors for mailboxes with new mails by using: +color sidebar_new red black +color sidebar white black - 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. + 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 - Note that the settings are not restored when you leave the mailbox. For - example, a command action to perform is to change the sorting methodbased - upon the mailbox being read: +macro index B ':toggle sidebar_visible^M' +macro pager B ':toggle sidebar_visible^M' - folder-hook mutt set sort=threads + 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'. - However, the sorting method is not restored to its previous value when - reading a different mailbox. To specify a default command, use the pattern - ``.'': +7. External Address Queries - folder-hook . set sort=date-sent + 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 $$qquueerryy__ccoommmmaanndd variable, you + specify the wrapper command to use. For example: -8. Keyboard macros +set query_command = "mutt_ldap_query.pl '%s'" - Usage: macromenu key sequence [description] + 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 + thensome other optional information. On error, or if there are no + matching addresses, return a non-zero exit code and a one line error + message. - 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 singlekey. + 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 + + 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 addressesto mail, start a new query, or have a new query + appended to the current responses. - 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 thecommas separating them. + 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 querymenu. At the query menu, you can select one or more addresses + to be added to the prompt. - 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 - specify it twice. Secondly, to specify a certain key such as up or to - invoke a function directly, you can use the format and - .For a listing of key names see the section on bind. - Functions are listed in the functions. +8. Mailbox Formats - The advantage with using function names directly is that the macros - willwork regardless of the current key bindings, so they are not dependent - on the user having particular key definitions. This makes them more - robustand portable, and also facilitates defining of macros in files used - by more than one user (eg. the system Muttngrc). + 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 newmailboxes, Mutt-ng uses the default specified with the + $$mmbbooxx__ttyyppee variable. - Optionally you can specify a descriptive text after sequence, which is - shown in the help screens. + _m_b_o_x. 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: - Note: Macro definitions (if any) listed in the help screen(s), are - silently truncated at the screen width, and are not wrapped. +From me@cs.hmc.edu Fri, 11 Apr 1997 11:44:56 PST -9. Using color and mono video attributes + to denote the start of a new message (this is often referred to as the + ``From_'' line). - Usage: colorobject foreground background [regexp] + _M_M_D_F. This is a variant of the _m_b_o_x format. Each message is surrounded + by lines containing ``^A^A^A^A'' (four control-A's). - Usage: colorindex foreground pattern + _M_H. A radical departure from _m_b_o_x and _M_M_D_F, 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 arerenamed with + a comma (,) prepended to the filename. _N_o_t_e_: Mutt detects this type of + mailbox by looking for either .mh_sequences or .xmhcache (needed to + distinguish normal directories from MH mailboxes). + + _M_a_i_l_d_i_r. The newest of the mailbox formats, used by the Qmail MTA (a + replacement for sendmail). Similar to _M_H, except that it adds three + subdirectories of the mailbox: _t_m_p, _n_e_w and _c_u_r .Filenames for the + messages are chosen in such a way they are unique, even when + twoprograms are writing the mailbox over NFS, which means that no file + locking is needed. - Usage: uncolorindex pattern [pattern ...] +9. Mailbox Shortcuts - 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). + 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. - object can be one of: + * ! -- refers to your $$ssppoooollffiillee (incoming) mailbox + * > -- refers to your $$mmbbooxx file + * < -- refers to your $$rreeccoorrdd file + * ^ -- refers to the current mailbox + * - or !! -- refers to the file you've last visited + * ~ -- refers to your home directory + * = or + -- refers to your $$ffoollddeerr directory + * @_a_l_i_a_s -- refers to the ssaavvee--hhooookk as determined by the address of + the alias - o attachment +10. Handling Mailing Lists - o body (match regexp in the body of messages) + Mutt-ng has a few configuration options that make dealing with large + amounts of mail easier. The first thing you must do is to let Mutt + know what addresses you consider to be mailing lists (technically this + does not have to be a mailing list, but that is what it is most often + used for), and what lists you are subscribed to. This is accomplished + through the use of the lliissttss commands in your muttrc. - o bold (highlighting bold patterns in the body of messages) + Now that Mutt-ng knows what your mailing lists are, it can do several + things, the first of which is the ability to show the name of a list + through which you received a message (i.e., of a subscribed list) in + the _i_n_d_e_x menu display. This is useful to distinguish between personal + and list mail in the same mailbox. In the $$iinnddeexx__ffoorrmmaatt variable, the + escape ``%L'' will return the string ``To '' when ``list'' + appears in the ``To'' field, and ``Cc '' when it appears in the + ``Cc'' field (otherwise it returns the name of the author). + + 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 _i_n_d_e_x menu and _p_a_g_e_r, 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). + + 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 $$ffoolllloowwuupp__ttoo option is set, mutt + will generate a Mail-Followup-To header which contains all the + recipients to whom you send this message, but not your address. This + indicates that group-replies or list-replies (also known as + ``followups'') to this message should only be sent to the original + recipients of the message, and not separately to you - you'll receive + your copy through one of the mailing lists you are subscribed to. + + Conversely, when group-replying or list-replying to a message which + has a Mail-Followup-To header, mutt will respect this header if the + $$hhoonnoorr__ffoolllloowwuupp__ttoo 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. - o error (error messages printed by Mutt-ng) + 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. - o header (match regexp in the message header) + 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 $$rreeppllyy__ttoo variable to help decide + which address to use. If set to _a_s_k_-_y_e_s or _a_s_k_-_n_o, you will be + prompted as to whether or not you would like to use the address given + inthe ``Reply-To'' field, or reply directly to the address given in + the ``From'' field. When set to _y_e_s, the ``Reply-To'' field will be + used when present. - o hdrdefault (default color of the message header in the pager) + The ``X-Label:'' header field can be used to further identify mailing + lists or list subject matter (or just to annotate messages + individually). The $$iinnddeexx__ffoorrmmaatt 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 procmailand other mail + filtering agents. + + Lastly, Mutt-ng has the ability to ssoorrtt the mailbox into tthhrreeaaddss. 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 + dealingwith large volume mailing lists easier because you can easily + delete uninteresting threads and quickly find topics of value. - o index (match pattern in the message index) +11. Editing threads - o indicator (arrow or bar used to indicate the current item in a menu) + 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. - o markers (the ``+'' markers at the beginning of wrapped lines in the - pager) +11.1. Linking threads - o message (informational messages) + 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. - o normal + You can also connect multiple children at once, tagging them and using + the tag-prefix command (';') or the auto_tag option. - o quoted (text matching $quote_regexp in the body of a message) +11.2. Breaking threads - o quoted1, quoted2, ..., quotedN (higher levels of quoting) + 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 (boundby default to #), + which will turn the subthread starting from the current message into a + whole different thread. - o search (highlighting of words in the pager) +12. Delivery Status Notification (DSN) Support - o signature + RRffCC  11889944 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.'' - o status (mode lines used to display info about the mailbox or message) + Users can make use of it in one of the following two ways: - o tilde (the ``~'' used to pad blank lines in the pager) + * 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. - o tree (thread tree drawn in the message index and attachment menu) + To support this, there are two variables: - o underline (highlighting underlined patterns in the body of messages) + * $$ddssnn__nnoottiiffyy is used to request receipts for different results + (such as failed message,message delivered, etc.). + * $$ddssnn__rreettuurrnn requests how much of your message should be returned + with the receipt (headers or full message). - foreground and background can be one of the following: + Please see the reference chapter for possible values. - o white +13. POP3 Support (OPTIONAL) - o black + If Mutt-ng was compiled with POP3 support (by running the _c_o_n_f_i_g_u_r_e + script with the _-_-_e_n_a_b_l_e_-_p_o_p flag), it has the ability to work with + mailboxes located on a remote POP3 server and fetch mail for local + browsing. - o green + You can access the remote POP3 mailbox by selecting the folder + pop://popserver/. - o magenta + You can select an alternative port by specifying it with the server, + i.e.: pop://popserver:port/. - o blue + You can also specify different username for each folder, i.e.: + pop://username@popserver[:port]/. - o cyan + 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 $$ppoopp__mmaaiill__cchheecckk variable, which + defaults to every 60 seconds. - o yellow + If Mutt-ng was compiled with SSL support (by running the _c_o_n_f_i_g_u_r_e + script with the _-_-_w_i_t_h_-_s_s_l flag), connections to POP3 servers can be + encrypted. This naturally requires that the server supports SSL + encrypted connections. To access a folder with POP3/SSL, you should + use pops: prefix, ie: pops://[username@]popserver[:port]/. - o red + Another way to access your POP3 mail is the _f_e_t_c_h_-_m_a_i_l function + (default: G). It allows to connect to ppoopp--hhoosstt ,fetch all your new + mail and place it in the local $$ssppoooollffiillee. After this point, Mutt-ng + runs exactly as if the mail had always been local. - o default + _N_o_t_e_: If you only need to fetch all messages to local mailbox you + should consider using a specialized program, such as fetchmail(1). - o colorx +14. IMAP Support (OPTIONAL) - foreground can optionally be prefixed with the keyword bright to make the - foreground color boldfaced (e.g., brightred). + If Mutt-ng was compiled with IMAP support (by running the _c_o_n_f_i_g_u_r_e + script with the _-_-_e_n_a_b_l_e_-_i_m_a_p flag), it has the ability to work with + folders located on a remote IMAP server. - If your terminal supports it, the special keyword default can be used as a - transparent color. The value brightdefault is also valid. If Mutt-ng is - linked against the S-Lang library, you also need to set the $COLORFGBG - environment variable to the default colors of your terminal for this to - work; for example (for Bourne-like shells): + You can access the remote inbox by selecting the folder via its URL: - set COLORFGBG="green;black" - export COLORFGBG +imap://imapserver/INBOX - Note: The S-Lang library requires you to use the lightgray and brown - keywords instead of white and yellow when setting this variable. + 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 - Note: The uncolor command can be applied to the index object only. It - removes entries from the list. You must specify the same pattern specified - in the color command for it to be removed. The pattern ``*'' is a special - token which means to clear the color index list of all entries. +imap://imapserver/path/to/folder - Mutt-ng also recognizes the keywords color0, color1 ,..., colorN-1 (N - being the number of colors supported by your terminal). This is useful - when you remap the colors for your display (for example by changing the - color associated with color2 for your xterm), since color names may then - lose their normal meaning. + where path/to/folder is the path of the folder you want to access. You + can select an alternative port by specifying it with the server, i.e.: - If your terminal does not support color, it is still possible change the - video attributes through the use of the ``mono'' command: +imap://imapserver:port/INBOX - Usage: monoobject attribute [regexp] + You can also specify different username for each folder by prenpending + your username and an @ symbol to the server's name. - Usage: monoindex attribute pattern + If Mutt-ng was compiled with SSL support (by running the _c_o_n_f_i_g_u_r_e + script with the _-_-_w_i_t_h_-_s_s_l 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 only need + to substitute the initial imap:// by imaps:// in the above examples. - Usage: unmonoindex pattern [pattern ...] + Note that not all servers use / as the hierarchy separator. Mutt-ng + should correctly notice which separator is being used by the server + and convertpaths accordingly. - where attribute is one of the following: + 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 _t_o_g_g_l_e_-_s_u_b_s_c_r_i_b_e_d command. See also the $$iimmaapp__lliisstt__ssuubbssccrriibbeedd + variable. - o none + Polling for new mail on an IMAP server can cause noticeable delays. + So, you'll want to carefully tune the $$iimmaapp__mmaaiill__cchheecckk and $$ttiimmeeoouutt + variables. - o bold + Note that if you are using mbox as the mail store on UW servers prior + tov12.250, the server has been reported to disconnect a client if + another client selects the same folder. - o underline +14.1. The Folder Browser - o reverse + 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). + +14.2. Authentication - o standout + 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". -10. Ignoring (weeding) unwanted message headers + 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 libraryinstalled on your system and compile + mutt with the _-_-_w_i_t_h_-_s_a_s_l flag. + + Mutt-ng will try whichever methods are compiled in and available on + the server, in the following order: SASL, ANONYMOUS, GSSAPI, CRAM-MD5, + LOGIN. - Usage: ignorepattern [pattern ...] + There are a few variables which control authentication: + * $$iimmaapp__uusseerr - 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}). + * $$iimmaapp__ppaassss - a password which you may preset, used by all + authentication methods where a password is needed. + * $$iimmaapp__aauutthheennttiiccaattoorrss - 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). - Usage: unignorepattern [pattern ...] +15. NNTP Support (OPTIONAL) - 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. + 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. - 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 ``content-''. ``ignore *'' will ignore all headers. + 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 $$nnnnttpp__nneewwssrrcc + 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. - 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 pattern. For example, if you do ``ignore x-'' it is possible to - ``unignore x-mailer''. +15.1. Again: Scoring - ``unignore *'' will remove all tokens from the ignore list. + 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 MMeessssaaggee + SSccoorriinngg. - For example: + What has not been discusses in detail is mutt-ng's built-in realname + filter. For may newsreaders including those for ``advanced users'' + like _s_l_r_n or _t_i_n, there are frequent request for such functionality. + The solutions offered often are complicated regular expressions. - # 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: + In mutt-ng this is as easy as -11. Alternative addresses +score ~* =42 - Usage: alternatesregexp [regexp ...] + 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 - Usage: unalternatesregexp [regexp ...] +score !~* =42 - 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 $reply_to.) + on the contrary applies a score of 42 to all messages _n_o_t matching + those criteria which are very strict: - 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. + * Email addresses must be valid according to RRffCC  22882222 + * 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 forso that + those 2 groups of messages are excluded from the strict rules. - The unalternates command can be used to write exceptions to alternates - patterns. If an address matches something in an alternates command, but - you nonetheless do not think it is from you, you can list a more precise - pattern under an unalternates command. +16. SMTP Support (OPTIONAL) - To remove a regular expression from the alternates list, use the - unalternates command with exactly the same regexp . Likewise, if the - regexp for a alternates command matches an entry on the unalternates list, - that unalternates entry will be removed. If the regexp for unalternates is - ``*'', all entries on alternates will be removed. + 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 ddssnn section) as well as handling the + 8BITMIME flag controlled via $$uussee__88bbiittmmiimmee. + + To enable sending mail directly via SMTP without an MTA such as + Postfix or SSMTP and the like, simply set the $$ssmmttpp__hhoosstt variable + pointing to your SMTP server. + + Authentication mechanisms are available via the $$ssmmttpp__uusseerr and + $$ssmmttpp__ppaassss variables. + + Transport Encryption via the StartTLS command is also available. For + this to work, first of all Mutt-ng must be built with SSL or GNUTLS. + Secondly, the $$ssmmttpp__uussee__ttllss 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 ifit + doesn't while switching back to unencrypted communication for the + first one. + + 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 + $$ssmmttpp__eennvveellooppee may be used to set the envelope different from the + From: header. -12. Format = Flowed +17. Managing multiple IMAP/POP/NNTP accounts (OPTIONAL) - 12.1. Introduction + 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 aaccccoouunntt--hhooookk command may help. This hook works like + ffoollddeerr--hhooookk but is invoked whenever you access a remote mailbox + (including inside the folder browser), not just when you open the + mailbox. - 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. + Some examples: - For introductory information on format=flowed messages, see - . +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"' - 12.2. Receiving: Display Setup +18. Start a WWW Browser on URLs (EXTERNAL) - 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: + If a message contains URLs (_u_n_i_f_i_e_d_ _r_e_s_o_u_r_c_e_ _l_o_c_a_t_o_r = address in the + WWW space like _h_t_t_p_:_/_/_w_w_w_._m_u_t_t_._o_r_g_/), 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 <> and the configuration + commands: +macro index \cb |urlview\n +macro pager \cb |urlview\n - set wrapmargin = 10 +19. Compressed folders Support (OPTIONAL) - The code above makes the line break 10 columns before the right side of - the terminal. + If Mutt-ng was compiled with compressed folders support (by running + the _c_o_n_f_i_g_u_r_e script with the _-_-_e_n_a_b_l_e_-_c_o_m_p_r_e_s_s_e_d 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. - If your terminal is so wide that the lines are embarrassingly long, you - can also set a maximum line length: + The most common use is to open compressed archived folders e.g. with + gzip. - set max_line_length = 120 + 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. - The example above will give you lines not longer than 120 characters. + There are three hooks defined (ooppeenn--hhooookk, cclloossee--hhooookk and aappppeenndd--hhooookk + )which define commands to uncompress and compress a folder and to + append messages to an existing compressed folder respectively. - When you view at format=flowed messages, you will often see the quoting - hierarchy like in the following example: + For 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. +open-hook \\.gz$ "gzip -cd %f > %t" +close-hook \\.gz$ "gzip -c %t > %f" +append-hook \\.gz$ "gzip -c %t >> %f" - 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: + You do not have to specify all of the commands. If you omit + aappppeenndd--hhooookk ,the folder will be open and closed again each time you + will add to it. If you omit cclloossee--hhooookk (or give empty command) , the + folder will be open in the mode. If you specify aappppeenndd--hhooookk though + you'll be able to append to the folder. - set stuff_quoted + 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 $$ssaavvee__eemmppttyy ,so that + the compressed file will be removed if you delete all of the messages. - This will lead to a nicer result that is easier to read: +19.1. Open a compressed mailbox for reading - > 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. + Usage: ooppeenn--hhooookk_r_e_g_e_x_p "_c_o_m_m_a_n_d" - 12.3. Sending + The _c_o_m_m_a_n_d is the command that can be used for opening the folders + whose names match _r_e_g_e_x_p. - If you want mutt-ng to send emails with format=flowed set, you need to - explicitly set it: + The _c_o_m_m_a_n_d 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. - set text_flowed + %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. - Additionally, you have to use an editor which supports writing - format=flowed-conforming emails. For vim(1), this is done by adding w to - the formatoptions (see :h formatoptions and :h fo-table) when writing - emails. - - 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: - - o > This is not the quote character but a right angle used for other - reasons + The _c_o_m_m_a_n_d should _n_o_t remove the original compressed file. The + _c_o_m_m_a_n_d should return non-zero exit status if it fails, so mutt knows + something's wrong. - Please make sure that you manually prepend a space to each of them. + Example: - 12.4. Additional Notes +open-hook \\.gz$ "gzip -cd %f > %t" - 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. + If the _c_o_m_m_a_n_d is empty, this operation is disabled for this file + type. -13. Mailing lists +19.2. Write a compressed mailbox - Usage: listsregexp [regexp ...] + Usage: cclloossee--hhooookk_r_e_g_e_x_p"_c_o_m_m_a_n_d" - Usage: unlistsregexp [regexp ...] + This is used to close the folder that was open with the ooppeenn--hhooookk + command after some changes were made to it. - Usage: subscriberegexp [regexp ...] + The _c_o_m_m_a_n_d string is the command that can be used for closing the + folders whose names match _r_e_g_e_x_p. It has the same format as in the + ooppeenn--hhooookk command. Temporary folder in this case is the folder + previously produced by the ooppeenn--hhooookk command. - Usage: unsubscriberegexp [regexp ...] + The _c_o_m_m_a_n_d should _n_o_t remove the decompressed file. The _c_o_m_m_a_n_d + should return non-zero exit status if it fails, so mutt knows + something's wrong. - 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 $followup_to configuration variable. - - More precisely, Mutt-ng maintains lists of patterns for the addresses of - known and subscribed mailing lists. Every subscribed mailing list is - known. To mark a mailing list as known, use the ``lists'' command. To mark - it as subscribed, use ``subscribe''. - - You can use regular expressions with both commands. To mark all messages - sent to a specific bug report's address on mutt's bug tracking system as - list mail, for instance, you could say ``subscribe [0-9]*@bugs.guug.de''. - Often, it's sufficient to just give a portion of the list's e-mail - address. + Example: - Specify as much of the address as you need to to remove ambiguity. For - example, if you've subscribed to the Mutt-ng mailing list, you will - receive mail addressed to mutt-users@mutt.org. So, to tell Mutt-ng that - this is a mailing list, you could add ``lists mutt-users'' to your - initialization file. To tell mutt that you are subscribed to it, add - ``subscribe mutt-users'' to your initialization file instead. If you also - happen to get mail from someone whose address is mutt-users@example.com, - you could use ``lists mutt-users@mutt\\.org'' or ``subscribe - mutt-users@mutt\\.org'' to match only mail from the actual list. +close-hook \\.gz$ "gzip -c %t > %f" - The ``unlists'' command is used to remove a token from the list of known - and subscribed mailing-lists. Use ``unlists *'' to remove all tokens. + If the _c_o_m_m_a_n_d is empty, this operation is disabled for this file + type, and the file can only be open in the readonly mode. - To remove a mailing list from the list of subscribed mailing lists, but - keep it on the list of known mailing lists, use ``unsubscribe''. + cclloossee--hhooookk is not called when you exit from the folder if the folder + was not changed. -14. Using Multiple spool mailboxes +19.3. Append a message to a compressed mailbox - Usage: mbox-hook [!]patternmailbox + Usage: aappppeenndd--hhooookk_r_e_g_e_x_p"_c_o_m_m_a_n_d" - This command is used to move read messages from a specified mailbox to - adifferent 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. + This command is used for saving to an existing compressed folder. The + _c_o_m_m_a_n_d is the command that can be used for appending to the folders + whose names match _r_e_g_e_x_p. It has the same format as in the ooppeenn--hhooookk + command. The temporary folder in this case contains the messages that + are beingappended. - 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). + The _c_o_m_m_a_n_d should _n_o_t remove the decompressed file. The _c_o_m_m_a_n_d + should return non-zero exit status if it fails, so mutt knows + something's wrong. -15. Defining mailboxes which receive mail + Example: - Usage: mailboxes[!]filename [filename ... ] +append-hook \\.gz$ "gzip -c %t >> %f" - Usage: unmailboxes[!]filename [filename ... ] + When aappppeenndd--hhooookk 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 ($$mmbbooxx__ttyyppee )type is always supposed (i.e. this is the + format used for the temporary folder). - 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. + If the file does not exist when you save to it, cclloossee--hhooookk is called, + and not aappppeenndd--hhooookk. aappppeenndd--hhooookk is only for appending to existing + folders. - When changing folders, pressing space will cycle through folders with new - mail. + If the _c_o_m_m_a_n_d is empty, this operation is disabled for this file + type. In this case, the folder will be open and closed again (using + ooppeenn--hhooookk and cclloossee--hhooookk respectively) each time you will add to it. - 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. +19.4. Encrypted folders - The ``unmailboxes'' command is used to remove a token from the list of - folders which receive mail. Use ``unmailboxes *'' to remove all tokens. + 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 + usethe following hooks: - 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. +open-hook \\.pgp$ "pgp -f < %f > %t" +close-hook \\.pgp$ "pgp -fe YourPgpUserIdOrKeyId < %t > %f" - 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. + Please note, that PGP does not support appending to an encrypted + folder, so there is no aappppeenndd--hhooookk defined. -16. User defined headers + _N_o_t_e_: the folder is temporary stored decrypted in the /tmp directory, + where it can be read by your system administrator.

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 extratypes 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. - 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: +1. Using MIME in Mutt - unmy_hdr to cc + 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. -17. Defining the order of headers when viewing messages +1.1. Viewing MIME messages in the pager - Usage: hdr_orderheader header [header ...] + 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. - Usage: unhdr_order[ * | header header ...] + 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 --] - With this command, you can specify an order in which mutt will attempt to - present headers to you when viewing messages. + Where the Description is the description or filename given for the + attachment, and the Encoding is one of + 7bit/8bit/quoted-printable/base64/binary. - ``unhdr_order *'' will clear all previous headers from the order list, - thus removing the header order effects set by the system-wide startup - file. + 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) --] - hdr_order From Date: From: To: Cc: Subject: +1.2. The Attachment Menu -18. Specify default save filename + The default binding for view-attachments is `v', which displays the + attachment menu for a message. The attachment menu displays a list + ofthe 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. - Usage: save-hook [!]patternfilename + Finally, you can apply the usual message-related functions (like + , and the reply and forward functions) to attachments + of type message/rfc822. - 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 . + See the help on the attachment menu for more information. - See pattern-hook for information on the exact format of pattern. +1.3. The Compose Menu - Examples: + 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. - save-hook me@(turing\\.)?cs\\.hmc\\.edu$ +elkins - save-hook aol\\.com$ +spam + Attachments appear as follows: +1 [text/plain, 7bit, 1K] /tmp/mutt-euler-8082-0 +2 [applica/x-gunzip, base64, 422K] ~/src/mutt-0.85.tar.gz - Also see the fcc-save-hook command. + 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). -19. Specify default Fcc: mailbox when composing +2. MIME Type configuration with mime.types - Usage: fcc-hook [!]patternmailbox + When you add an attachment to your mail message, Mutt-ng searches your + personal mime.types file within $HOME and then the system mime.types + file at /usr/local/share/mutt/mime.types or /etc/mime.types + + 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 + + A sample mime.types file comes with the Mutt-ng distribution, and + should contain most of the MIME types you are likely to use. + + 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. - 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 $record mailbox. +3. MIME Viewer configuration with mailcap - See pattern-hook for information on the exact format of pattern. + Mutt-ng supports RRffCC  11552244 MIME Configuration, in particular the Unix + specific format specified in Appendix A of the RfC. This file format + is commonly referred to as the mailcap format. Many MIME compliant + programs utilize the mailcap format, allowing you to specify handling + for all MIME types in one place for all programs. Programs known to + use this format include Netscape, XMosaic, lynx and metamail. - Example: + In order to handle various MIME types that Mutt-ng can not handle + internally, Mutt-ng parses a series of external configuration files to + find an external handler. The default search string for these files is + a colon delimited list set to +${HOME}/.mailcap:/usr/local/share/mutt/mailcap:/etc/mailcap:/etc/mailcap:/usr/e +tc/mailcap:/usr/local/etc/mailcap - fcc-hook [@.]aol\\.com$ +spammers + where $HOME is your home directory. - The above will save a copy of all messages going to the aol.com domain to - the `+spammers' mailbox by default. Also see the fcc-save-hook command. + In particular, the metamail distribution will install a mailcap file, + usually as /usr/local/etc/mailcap, which contains some baseline + entries. -20. Specify default save filename and default Fcc: mailbox at once +3.1. The Basics of the mailcap file - Usage: fcc-save-hook [!]patternmailbox + A mailcap file consists of a series of lines which are comments, + blank, or definitions. - This command is a shortcut, equivalent to doing both a fcc-hook and a - save-hook with its arguments. + A comment line consists of a # character followed by anything you + want. -21. Change settings based upon message recipients + A blank line is blank. - Usage: reply-hook [!]patterncommand + A definition line consists of a content type, a view command, and any + number of optional fields. Each field of a definition line is + dividedby a semicolon ';' character. + + 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. + + 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. - Usage: send-hook [!]patterncommand + So, in the simplest form, you can send a text/plain message to the + external pager more on stdin: +text/plain; more - Usage: send2-hook [!]patterncommand + Or, you could send the message as a file: +text/plain; more %s - 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. + Perhaps you would like to use lynx to interactively view a text/html + message: +text/html; lynx %s - 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. + In this case, lynx does not support viewing a file from stdin, so you + must use the %s syntax. _N_o_t_e_:_S_o_m_e_ _o_l_d_e_r_ _v_e_r_s_i_o_n_s_ _o_f_ _l_y_n_x_ _c_o_n_t_a_i_n_ _a_ _b_u_g + _w_h_e_r_e_ _t_h_e_y_ _w_i_l_l_ _c_h_e_c_k_ _t_h_e_ _m_a_i_l_c_a_p_ _f_i_l_e_ _f_o_r_ _a_ _v_i_e_w_e_r_ _f_o_r_ _t_e_x_t_/_h_t_m_l_. + _T_h_e_y_ _w_i_l_l_ _f_i_n_d_ _t_h_e_ _l_i_n_e_ _w_h_i_c_h_ _c_a_l_l_s_ _l_y_n_x_,_ _a_n_d_ _r_u_n_ _i_t_._ _T_h_i_s_ _c_a_u_s_e_s_ _l_y_n_x + _t_o_ _c_o_n_t_i_n_u_o_u_s_l_y_ _s_p_a_w_n_ _i_t_s_e_l_f_ _t_o_ _v_i_e_w_ _t_h_e_ _o_b_j_e_c_t_. - 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. + On the other hand, maybe you don't want to use lynx interactively, + youjust want to have it convert the text/html to text/plain, then you + can use: +text/html; lynx -dump %s | more - 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). + 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 - See pattern-hook for information on the exact format of pattern. + This is the simplest form of a mailcap file. - Example: send-hook mutt "set mime_forward signature=''" +3.2. Secure use of mailcap - 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. + 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 $$mmaaiillccaapp__ssaanniittiizzee + variable. - 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. + 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: -22. Change settings before formatting a message + _K_e_e_p_ _t_h_e_ _%_-_e_x_p_a_n_d_o_s_ _a_w_a_y_ _f_r_o_m_ _s_h_e_l_l_ _q_u_o_t_i_n_g_. 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. - Usage: message-hook [!]patterncommand + 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): - 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.

Advanced mailcap Usage - Example: +3.3.1. Optional Fields - message-hook ~A 'set pager=builtin' - message-hook '~f freshmeat-news' 'set pager="less \"+/^ subject:.*\""' + 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: -23. Choosing the cryptographic key of the recipient + 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: - Usage: crypt-hookpatternkeyid +text/html; lynx -dump %s ; copiousoutput - 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 - wouldnormally 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 will cause lynx to format the text/html output as + text/plain and Mutt-ng will use your standard pager to display + the results. - 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. + needsterminal + Mutt-ng uses this flag when viewing attachments with aauuttoo__vviieeww, + in order to decide whether it should honor the setting of the + $$wwaaiitt__kkeeyy variable or not. When an attachment is viewed using + an interactive program, and the corresponding mailcap entry has + a _n_e_e_d_s_t_e_r_m_i_n_a_l flag, Mutt-ng will use $$wwaaiitt__kkeeyy and the exit + statusof 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. -24. Adding key sequences to the keyboard buffer + compose= + 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. - Usage: pushstring + composetyped= + 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. - 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. For - example, the following command will automatically collapse all threads - when entering a folder: + print= + This flag specifies the command to use to print a specific MIME + type. Mutt-ng supports this from the attachment and compose + menus. - folder-hook . 'push ' + edit= + 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. -25. Executing functions + nametemplate=
