Overview - _2_._2 _E_d_i_t_i_n_g _I_n_p_u_t _F_i_e_l_d_s + 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. - Mutt-ng has a builtin line editor which is used as the primary way to input - textual data such as email addresses or filenames. The keys used to move - around while editing are very similar to those of Emacs. - - ^A or bol move to the start of the line - ^B or backward-char move back one char - Esc B backward-word move back one word - ^D or delete-char delete the char under the cursor - ^E or eol move to the end of the line - ^F or forward-char move forward one char - Esc F forward-word move forward one word - complete complete filename or alias - ^T complete-query complete address with query - ^K kill-eol delete to the end of the line - ESC d kill-eow delete to the end of the word - ^W kill-word kill the word in front of the cursor - ^U kill-line delete entire line - ^V quote-char quote the next typed key - history-up recall previous string from history - history-down recall next string from history - backspace kill the char in front of the cursor - Esc u upcase-word convert word to upper case - Esc l downcase-word convert word to lower case - Esc c capitalize-word capitalize the word - ^G n/a abort - n/a finish editing + 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. - You can remap the _e_d_i_t_o_r functions using the _b_i_n_d (section 3.3 , page 17) com- - mand.

Mailing Lists - Similar to many other mail clients, there are two modes in which mail is read - in Mutt-ng.

For one, it - will accept and translate the ``standard'' nroff sequences for bold and under- - line. These sequences are a series of either the letter, backspace (^H), the - letter again for bold or the letter, backspace, ``_'' for denoting underline. - Mutt-ng will attempt to display these in bold and underline respectively if - your terminal supports them. If not, you can use the bold and underline _c_o_l_o_r - (section 3.7 , page 21) objects to specify a color or mono attribute for them. + Visit channel #muttng on irc.freenode.net (www.freenode.net) to chat with other people interested in Mutt-ng. - Additionally, the internal pager supports the ANSI escape sequences for charac- - ter attributes.

Basic Concepts - Bouncing a message sends the message as is to the recipient you specify. For- - warding a message allows you to add comments or modify the message you are for- - warding. These items are discussed in greater detail in the next chapter - _`_`_F_o_r_w_a_r_d_i_n_g _a_n_d _B_o_u_n_c_i_n_g _M_a_i_l_'_' (section 2.5 , page 13). + 1.1. Screens and Menus + 1.2.

Patterns - Mutt-ng will then enter the _c_o_m_p_o_s_e menu and prompt you for the recipients to - place on the ``To:'' header field. Next, it will ask you for the ``Subject:'' - field for the message, providing a default if you are replying to or forwarding - a message. See also _$_a_s_k_c_c (section 6.3.10 , page 67), _$_a_s_k_b_c_c (section - 6.3.9 , page 66), _$_a_u_t_o_e_d_i_t (section 6.3.17 , page 69), _$_b_o_u_n_c_e (section - 6.3.20 , page 69), and _$_f_a_s_t___r_e_p_l_y (section 6.3.60 , page 78) for changing - how Mutt-ng asks these questions. + 2. Screens and Menus - Mutt-ng will then automatically start your _$_e_d_i_t_o_r (section 6.3.55 , page 77) - on the message body. If the _$_e_d_i_t___h_e_a_d_e_r_s (section 6.3.54 , page 77) variable - is set, the headers will be at the top of the message in your editor. Any mes- - sages you are replying to will be added in sort order to the message, with - appropriate _$_a_t_t_r_i_b_u_t_i_o_n (section 6.3.15 , page 68), _$_i_n_d_e_n_t___s_t_r_i_n_g (section - 6.3.109 , page 90) and _$_p_o_s_t___i_n_d_e_n_t___s_t_r_i_n_g (section 6.3.212 , page 116). - When forwarding a message, if the _$_m_i_m_e___f_o_r_w_a_r_d (section 6.3.136 , page 97) - variable is unset, a copy of the forwarded message will be included. If you - have specified a _$_s_i_g_n_a_t_u_r_e (section 6.3.259 , page 127), it will be appended - to the message. - - Once you have finished editing the body of your mail message, you are returned - to the _c_o_m_p_o_s_e menu. The following options are available: - - The Mutt-ng E-Mail Client 11 - - a attach-file attach a file - A attach-message attach message(s) to the message - ESC k attach-key attach a PGP public key - d edit-description edit description on attachment - D detach-file detach a file - t edit-to edit the To field - ESC f edit-from edit the From field - r edit-reply-to edit the Reply-To field - c edit-cc edit the Cc field - b edit-bcc edit the Bcc field - y send-message send the message - s edit-subject edit the Subject - S smime-menu select S/MIME options - f edit-fcc specify an ``Fcc'' mailbox - p pgp-menu select PGP options - P postpone-message postpone this message until later - q quit quit (abort) sending the message - w write-fcc write the message to a folder - i ispell check spelling (if available on your system) - ^F forget-passphrase wipe passphrase(s) from memory - - NNoottee:: The attach-message function will prompt you for a folder to attach mes- - sages from. You can now tag messages in that folder and they will be attached - to the message you are sending. Note that certain operations like composing a - new mail, replying, forwarding, etc. are not permitted when you are in that - folder. The %r in _$_s_t_a_t_u_s___f_o_r_m_a_t (section 6.3.305 , page 138) will change to a - 'A' to indicate that you are in attach-message mode. - - _2_._4_._1 _E_d_i_t_i_n_g _t_h_e _m_e_s_s_a_g_e _h_e_a_d_e_r - - When editing the header of your outgoing message, there are a couple of special - features available. - - If you specify - - Fcc: _f_i_l_e_n_a_m_e - - Mutt-ng will pick up _f_i_l_e_n_a_m_e just as if you had used the _e_d_i_t_-_f_c_c function in - the _c_o_m_p_o_s_e menu. - - You can also attach files to your message by specifying - - Attach: _f_i_l_e_n_a_m_e [ _d_e_s_c_r_i_p_t_i_o_n ] - - where _f_i_l_e_n_a_m_e is the file to attach and _d_e_s_c_r_i_p_t_i_o_n is an optional string to - use as the description of the attached file. - - When replying to messages, if you remove the _I_n_-_R_e_p_l_y_-_T_o_: field from the header - field, Mutt-ng will not generate a _R_e_f_e_r_e_n_c_e_s_: field, which allows you to cre- - ate a new message thread. - - Also see _e_d_i_t___h_e_a_d_e_r_s (section 6.3.54 , page 77). - - The Mutt-ng E-Mail Client 12 - - _2_._4_._2 _U_s_i_n_g _M_u_t_t_-_n_g _w_i_t_h _P_G_P - - If you want to use PGP, you can specify - - Pgp: [ E | S | S_<_i_d_> ] - - ``E'' encrypts, ``S'' signs and ``S'' signs with the given key, setting - _$_p_g_p___s_i_g_n___a_s (section 6.3.192 , page 112) permanently. - - 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. - - In these cases, you are dropped into a menu with a list of keys from which you - can select one. When you quit this menu, or mutt can't find any matching keys, - you are prompted for a user ID. You can, as usually, abort this prompt using - ^G. When you do so, mutt will return to the compose screen. - - Once you have successfully finished the key selection, the message will be - encrypted using the selected public keys, and sent out. - - Most fields of the entries in the key selection menu (see also _$_p_g_p___e_n_t_r_y___f_o_r_- - _m_a_t (section 6.3.179 , page 109)) have obvious meanings. But some explana- - tions on the capabilities, flags, and validity fields are in order. - - The flags sequence (%f) will expand to one of the following flags: - - R The key has been revoked and can't be used. - X The key is expired and can't be used. - d You have marked the key as disabled. - c There are unknown critical self-signature - packets. - - The capabilities field (%c) expands to a two-character sequence representing a - key's capabilities. The first character gives the key's encryption capabili- - ties: A minus sign (--) 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 ee 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 ``ss'' 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. - - The Mutt-ng E-Mail Client 13 + 2.1.

Reading Mail - The Index and Pager - You may also have configured mutt to co-operate with Mixmaster, an anonymous - remailer. Mixmaster permits you to send your messages anonymously using a - chain of remailers. Mixmaster support in mutt is for mixmaster version 2.04 - (beta 45 appears to be the latest) and 2.03. It does not support earlier ver- - sions or the later so-called version 3 betas, of which the latest appears to be - called 2.9b23. + 5.1. The Message Index + 5.2. The Pager + 5.3.

Sending anonymous messages via mixmaster - You can navigate in the chain using the chain-prev and chain-next functions, - which are by default bound to the left and right arrows and to the h and l keys - (think vi keyboard bindings). To insert a remailer at the current chain posi- - tion, use the insert function. To append a remailer behind the current chain - position, use select-entry or append. You can also delete entries from the - chain, using the corresponding function. Finally, to abandon your changes, - leave the menu, or accept them pressing (by default) the Return key. + 7. Forwarding and Bouncing Mail + 8. Postponing Mail - Note that different remailers do have different capabilities, indicated in the - %c entry of the remailer menu lines (see _$_m_i_x___e_n_t_r_y___f_o_r_m_a_t (section 6.3.139 , - page 98)). Most important is the ``middleman'' capability, indicated by a cap- - ital ``M'': This means that the remailer in question cannot be used as the - final element of a chain, but will only forward messages to other mixmaster - remailers. For details on the other capabilities, please have a look at the - mixmaster documentation. - - _2_._5 _F_o_r_w_a_r_d_i_n_g _a_n_d _B_o_u_n_c_i_n_g _M_a_i_l - - Bouncing and forwarding let you send an existing message to recipients that you - specify. Bouncing a message uses the _s_e_n_d_m_a_i_l (section 6.3.247 , page 124) - command to send a copy to alternative addresses as if they were the message's - original recipients. Forwarding a message, on the other hand, allows you to - modify the message before it is resent (for example, by adding your own com- - ments). - - The following keys are bound by default: - - f forward forward message - b bounce bounce (remail) message - - Forwarding can be done by including the original message in the new message's - body (surrounded by indicating lines) or including it as a MIME attachment, - depending on the value of the _$_m_i_m_e___f_o_r_w_a_r_d (section 6.3.136 , page 97) vari- - able. Decoding of attachments, like in the pager, can be controlled by the - _$_f_o_r_w_a_r_d___d_e_c_o_d_e (section 6.3.69 , page 81) and _$_m_i_m_e___f_o_r_w_a_r_d___d_e_c_o_d_e (section - - The Mutt-ng E-Mail Client 14 - - 6.3.137 , page 98) variables, respectively. The desired forwarding format may - depend on the content, therefore _$_m_i_m_e___f_o_r_w_a_r_d is a quadoption which, for exam- - ple, can be set to ``ask-no''. - - The inclusion of headers is controlled by the current setting of the _$_w_e_e_d - (section 6.3.333 , page 146) variable, unless _m_i_m_e___f_o_r_w_a_r_d (section 6.3.136 , - page 97) is set. - - Editing the message to forward follows the same procedure as sending or reply- - ing to a message does. - - _2_._6 _P_o_s_t_p_o_n_i_n_g _M_a_i_l - - 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 _$_p_o_s_t_p_o_n_e_d (section 6.3.214 , page 117) variable. This means that you can - recall the message even if you exit Mutt-ng and then restart it at a later - time. - - Once a message is postponed, there are several ways to resume it. From the - command line you can use the ``-p'' option, or if you _c_o_m_p_o_s_e a new message - from the _i_n_d_e_x or _p_a_g_e_r you will be prompted if postponed messages exist. If - multiple messages are currently postponed, the _p_o_s_t_p_o_n_e_d menu will pop up and - you can select which message you would like to resume. - - NNoottee:: If you postpone a reply to a message, the reply setting of the message is - only updated when you actually finish the message and send it. Also, you must - be in the same folder with the message you replied to for the status of the - message to be updated. - - See also the _$_p_o_s_t_p_o_n_e (section 6.3.213 , page 116) quad-option. - - _2_._7 _R_e_a_d_i_n_g _n_e_w_s _v_i_a _N_N_T_P - - If compiled with ``--enable-nntp'' option, Mutt-ng can read news from - newsserver via NNTP. You can open a newsgroup with function ``change-news- - group'' (default: i). Default newsserver can be obtained from _N_N_T_P_S_E_R_V_E_R envi- - ronment variable. Like other news readers, info about subscribed newsgroups is - saved in file by _$_n_n_t_p___n_e_w_s_r_c (section 6.3.156 , page 103) variable. Article - headers are cached and can be loaded from file when newsgroup entered instead - loading from newsserver. - - _3_. _C_o_n_f_i_g_u_r_a_t_i_o_n - - 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'' _c_o_m_m_a_n_d _l_i_n_e (section 6.1 , page 62) 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 +1. Basic Concepts - The Mutt-ng E-Mail Client 15 +1.1. Screens and Menus - 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. + mutt-ng offers different screens of which every has its special purpose: + * The index displays the contents of the currently opened mailbox. + * The pager is responsible for displaying messages, that is, the header, the body and all attached parts. + * The file browser offers operations on and displays information of all folders mutt-ng should watch for mail. + * The sidebar offers a permanent view of which mailboxes contain how many total, new and/or flagged mails. + * The help screen lists for all currently available commands how to invoke them as well as a short description. + * The compose menu is a comfortable interface take last actions before sending mail: change subjects, attach files, remove attachements, etc. + * The attachement menu gives a summary and the tree structure of the attachements of the current message. + * The alias menu lists all or a fraction of the aliases a user has defined. + * The key menu used in connection with encryption lets users choose the right key to encrypt with. - .muttrc (or .muttngrc for Mutt-ng) is the file where you will usually place - your _c_o_m_m_a_n_d_s (section 6.2 , page 62) to configure Mutt-ng. + When mutt-ng is started without any further options, it'll open the users default mailbox and display the index. - In addition, mutt supports version specific configuration files that are parsed - instead of the default files as explained above. For instance, if your system - has a Muttrc-0.88 file in the system configuration directory, and you are run- - ning version 0.88 of mutt, this file will be sourced instead of the Muttngrc - file. The same is true of the user configuration file, if you have a file - .muttrc-0.88.6 in your home directory, when you run mutt version 0.88.6, it - will source this file instead of the default .muttrc file. The version number - is the same which is visible using the ``-v'' _c_o_m_m_a_n_d _l_i_n_e (section 6.1 , page - 62) switch or using the show-version key (default: V) from the index menu. +1.2. Configuration - _3_._1 _S_y_n_t_a_x _o_f _I_n_i_t_i_a_l_i_z_a_t_i_o_n _F_i_l_e_s + 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.) - An initialization file consists of a series of _c_o_m_m_a_n_d_s (section 6.2 , page - 62). Each line of the file may contain one or more commands. When multiple - commands are used, they must be separated by a semicolon (;). + Mutt-ng is configured using configuration files which allow users to add comments or manage them via version control systems to ease maintenance. - set realname='Mutt-ng user' ; ignore x- + 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. - 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, +1.3. Functions - my_hdr X-Disclaimer: Why are you listening to me? # This is a comment + 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. - Single quotes (') and double quotes (') can be used to quote strings which con- - tain 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 sin- - gle 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 nnoott for single quotes. +1.4. Interaction - \ quotes the next character, just as in shells such as bash and zsh. For exam- - ple, if want to put quotes ``''' inside of a string, you can use ``\'' to force - the next character to be a literal instead of interpreted character. + Mutt-ng has two basic concepts of user interaction: + 1. There is one dedicated line on the screen used to query the user for input, issue any command, query variables and display error and informational messages. As for every type of user input, this requires manual action leading to the need of input. + 2. The automatized interface for interaction are the so called hooks. Hooks specify actions the user wants to be performed at well-defined situations: what to do when entering which folder, what to do when displaying or replying to what kind of message, etc. These are optional, i.e. a user doesn't need to specify them but can do so. - set realname="Michael \"MuttDude\" Elkins" +1.5. Modularization - ``\\'' means to insert a literal ``\'' into the line. ``\n'' and ``\r'' have - their usual C meanings of linefeed and carriage-return, respectively. + 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. - 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. +1.6. Patterns - The Mutt-ng E-Mail Client 16 + 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. - 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 ``#''. +2. Screens and Menus - # folder-hook . \ - set realname="Michael \"MuttDude\" Elkins" +2.1. Index - 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! + 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. - Abstract example: +2.2. Pager - line1\ - line2a # line2b\ - line3\ - line4 - line5 + 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. - 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. + 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. - It is also possible to substitute the output of a Unix command in an initial- - ization file. This is accomplished by enclosing the command in backquotes - (``). For example, + 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. - my_hdr X-Operating-System: `uname -a` +2.3. File Browser - 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 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. - 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 ``$''. For example, +2.4. Sidebar - set record=+sent_on_$HOSTNAME + 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. - The commands understood by mutt are explained in the next paragraphs. For a - complete list, see the _c_o_m_m_a_n_d _r_e_f_e_r_e_n_c_e (section 6.2 , page 62). +2.5. Help - _3_._2 _D_e_f_i_n_i_n_g_/_U_s_i_n_g _a_l_i_a_s_e_s + 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). - Usage: alias _k_e_y _a_d_d_r_e_s_s [ , _a_d_d_r_e_s_s, ... ] +2.6. Compose Menu - The Mutt-ng E-Mail Client 17 + 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. - 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. + Also, it's used to attach messages, news articles or files to a message, to re-edit any attachment including the message itself. - NNoottee:: if you want to create an alias for a group (by specifying more than one - address), you mmuusstt separate the addresses with a comma (``,''). +2.7. Alias Menu - To remove an alias or aliases (``*'' means all aliases): + 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. - unalias [ * | _k_e_y _._._. ] +2.8. Attachment Menu - alias muttdude me@cs.hmc.edu (Michael Elkins) - alias theguys manny, moe, jack + 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. - Unlike other mailers, Mutt-ng doesn't require aliases to be defined in a spe- - cial file. The alias command can appear anywhere in a configuration file, as - long as this file is _s_o_u_r_c_e_d (section 3.26 , page 32). Consequently, you can - have multiple alias files, or you can have all aliases defined in your muttrc. +2.9. Key Menu - On the other hand, the _c_r_e_a_t_e_-_a_l_i_a_s (section 2.3.4 , page 7) function can use - only one file, the one pointed to by the _$_a_l_i_a_s___f_i_l_e (section 6.3.3 , page 65) - 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 _s_o_u_r_c_e (section - 3.26 , page 32) this file too. + FIXME - For example: +3. Moving Around in Menus - source /usr/local/share/Mutt-ng.aliases - source ~/.mail_aliases - set alias_file=~/.mail_aliases + Information is presented in menus, very similar to ELM. Here is a tableshowing the common keys used to navigate menus in Mutt-ng. - To use aliases, you merely use the alias at any place in mutt where mutt - prompts 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 _$_e_d_i_t___h_e_a_d_e_r_s - (section 6.3.54 , page 77) variable set. + Table 2.1.

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. +4. Editing Input Fields - 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. + 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. - _3_._3 _C_h_a_n_g_i_n_g _t_h_e _d_e_f_a_u_l_t _k_e_y _b_i_n_d_i_n_g_s + Table 2.2.

For example, to make the Delete key delete the character in front of the cursor rather than under, you could use - The Mutt-ng E-Mail Client 18 + bind editor backspace - This command allows you to change the default key bindings (operation invoked - when pressing a key). +5. Reading Mail - The Index and Pager - _m_a_p specifies in which menu the binding belongs. Multiple maps may be speci- - fied by separating them with commas (no additional whitespace is allowed). The - currently defined maps are: + 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.'' - generic - This is not a real menu, but is used as a fallback for all of the - other menus except for the pager and editor modes. If a key is not - defined in another menu, Mutt-ng will look for a binding to use in - this menu. This allows you to bind a key to a certain function in - multiple menus instead of having multiple bind statements to accom- - plish the same task. + The next few sections describe the functions provided in each of these modes. - alias - The alias menu is the list of your personal aliases as defined in - your muttrc.

For one, it will accept and translate the ``standard'' nroff sequences forbold and underline. These sequences are a series of either the letter, backspace (^H), the letter again for bold or the letter, backspace, ``_'' for denoting underline. Mutt-ng will attempt to display these in bold and underline respectively if your terminal supports them. If not, you can use the bold and underline color objects to specify a color or mono attribute for them. - well as _\_C is ignored, so that _\_C_A, _\_C_a, _\_c_A and _\_c_a are all equivalent.

This is useful - to properly display messages which are tagged with a character set name not - known to mutt. + 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. - 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. + For example, you could use %?M?(#%03M)&(%4l)? in $index_format to optionally display the number of hidden messages if the thread is collapsed. - _3_._5 _S_e_t_t_i_n_g _v_a_r_i_a_b_l_e_s _b_a_s_e_d _u_p_o_n _m_a_i_l_b_o_x + See also the $strict_threads variable. - The Mutt-ng E-Mail Client 20 +5.4. Miscellaneous Functions - Usage: folder-hook [!]_r_e_g_e_x_p _c_o_m_m_a_n_d + (default: a) - It is often desirable to change settings based on which mailbox you are read- - ing. The folder-hook 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 - folder-hook's, they are executed in the order given in the muttrc. + 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 $alias_file does not add the aliases specified there-in, you must also source the file. - NNoottee:: if you use the ``!'' shortcut for _$_s_p_o_o_l_f_i_l_e (section 6.3.295 , page - 136) 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. + (default: ESC P) - Note that the settings are _n_o_t restored when you leave the mailbox. For exam- - ple, a command action to perform is to change the sorting method based upon the - mailbox being read: + 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. - folder-hook mutt set sort=threads + (default: h) - However, the sorting method is not restored to its previous value when reading - a different mailbox.

After you have finished editing, the changed message will be appended to the current folder, and the original message will be marked for deletion. - 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 ] + (default: ) (default: ^E on the attachment menu, and in the pager and index menus; ^T on the compose menu) - 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 single key. + 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. - _m_e_n_u is the _m_a_p (section 3.3 , page 17) which the macro will be bound. Multi- - ple maps may be specified by separating multiple menu arguments by commas. - Whitespace may not be used in between the menu arguments and the commas sepa- - rating them. + 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. - _k_e_y and _s_e_q_u_e_n_c_e are expanded by the same rules as the _k_e_y _b_i_n_d_i_n_g_s (section - 3.3 , page 17). 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 use _^_^. 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 _k_e_y _b_i_n_d_i_n_g_s (section - 3.3 , page 17). Functions are listed in the _f_u_n_c_t_i_o_n _r_e_f_e_r_e_n_c_e (section - 6.4 , page 147). + (default: :) - The advantage with using function names directly is that the macros will work - regardless of the current key bindings, so they are not dependent on the user - having particular key definitions.

After that, mutt-ng got the most important information from you, and starts up an editor where you can then enter your email. - The Mutt-ng E-Mail Client 22 + The editor that is called is selected in the following way: you can e.g. set it in the mutt-ng configuration: +set editor = "vim +/^$/ -c ':set tw=72'" +set editor = "nano" +set editor = "emacs" - +o signature + 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. - +o status (mode lines used to display info about the mailbox or message) + 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. - +o tilde (the ``~'' used to pad blank lines in the pager) + Below that, you see a list of "attachments".

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. - _f_o_r_e_g_r_o_u_n_d can optionally be prefixed with the keyword bright to make the fore- - ground color boldfaced (e.g., brightred). + 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. - 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 _C_O_L_O_R_F_G_B_G environ- - ment variable to the default colors of your terminal for this to work; for - example (for Bourne-like shells): +6.2.2. Group Replies - set COLORFGBG="green;black" - export COLORFGBG + 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. - NNoottee:: 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. +6.2.3. List Replies - NNoottee:: The uncolor command can be applied to the index object only. It removes - entries from the list. You mmuusstt 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. + 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. - The Mutt-ng E-Mail Client 23 + To do a list reply, simply press L. If the email contains a Mail-Followup-To: header, its value will be used as reply address. Otherwise, mutt-ng searches through all mail addresses in the original message and tries to match them a list of regular expressions which can be specified using the lists command. If any of the regular expression matches, a mailing list address has been found, and it will be used as reply address. +lists linuxevent@luga\.at vuln-dev@ mutt-ng-users@ - Mutt-ng also recognizes the keywords _c_o_l_o_r_0, _c_o_l_o_r_1, ..., _c_o_l_o_rNN--11 (NN 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 - _c_o_l_o_r_2 for your xterm), since color names may then lose their normal meaning. + 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. - If your terminal does not support color, it is still possible change the video - attributes through the use of the ``mono'' command: +6.3.

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. - Usage: [un]ignore _p_a_t_t_e_r_n [ _p_a_t_t_e_r_n ... ] + In these cases, you are dropped into a menu with a list of keys from which you can select one. When you quit this menu, or mutt can't find any matching keys, you are prompted for a user ID. You can, as usually, abort this prompt using ^G. When you do so, mutt will return to the compose screen. - 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. + Once you have successfully finished the key selection, the message will be encrypted using the selected public keys, and sent out. - You do not need to specify the full header field name. For example, ``ignore - content-'' will ignore all header fields that begin with the pattern ``con- - tent-''. ``ignore *'' will ignore all headers. + 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. - To remove a previously added token from the list, use the ``unignore'' command. - The ``unignore'' command will make Mutt-ng display headers with the given pat- - tern. For example, if you do ``ignore x-'' it is possible to ``unignore x- - mailer''. + The flags sequence (%f) will expand to one of the following flags: - ``unignore *'' will remove all tokens from the ignore list. + Table 2.10.

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. - # 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: + 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. - The Mutt-ng E-Mail Client 24 + 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. - _3_._9 _A_l_t_e_r_n_a_t_i_v_e _a_d_d_r_e_s_s_e_s +6.5. Sending anonymous messages via mixmaster - Usage: [un]alternates _r_e_g_e_x_p [ _r_e_g_e_x_p ... ] + 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. - 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 - _$_r_e_p_l_y___t_o (section 6.3.233 , page 121).) + 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. - 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. + The chain selection screen is divided into two parts. In the (larger) upper part, you get a list of remailers you may use. In the lower part, you see the currently selected chain of remailers. - The unalternates command can be used to write exceptions to alternates pat- - terns. If an address matches something in an alternates command, but you none- - theless do not think it is from you, you can list a more precise pattern under - an unalternates command. + 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. - To remove a regular expression from the alternates list, use the unalternates - command with exactly the same _r_e_g_e_x_p. Likewise, if the _r_e_g_e_x_p for a alternates - command matches an entry on the unalternates list, that unalternates entry will - be removed. If the _r_e_g_e_x_p for unalternates is ``*'', _a_l_l _e_n_t_r_i_e_s on alternates - will be removed. + Note that different remailers do have different capabilities, indicated in the %c entry of the remailer menu lines (see $mix_entry_format). Most important is the ``middleman'' capability, indicated by a capital ``M'': This means that the remailer in question cannot be used as the final element of a chain, but will only forward messages to other mixmaster remailers. For details on the other capabilities, please have a look at the mixmaster documentation. - _3_._1_0 _M_a_i_l_i_n_g _l_i_s_t_s +7. Forwarding and Bouncing Mail - Usage: [un]lists _r_e_g_e_x_p [ _r_e_g_e_x_p ... ] + Often, it is necessary to forward mails to other people. Therefore, mutt-ng supports forwarding messages in two different ways. - Usage: [un]subscribe _r_e_g_e_x_p [ _r_e_g_e_x_p ... ] + The first one is regular forwarding, as you probably know it from other mail clients. You simply press f, enter the recipient email address, the subject of the forwarded email, and then you can edit the message to be forwarded in the editor. The forwarded message is separated from the rest of the message via the two following markers: +----- Forwarded message from Lucas User ----- - Mutt-ng has a few nice features for _h_a_n_d_l_i_n_g _m_a_i_l_i_n_g _l_i_s_t_s (section 4.9 , page - 44). In order to take advantage of them, you must specify which addresses - belong to mailing lists, and which mailing lists you are subscribed to. Once - you have done this, the _l_i_s_t_-_r_e_p_l_y (section 2.3.4 , page 8) function will work - for all known lists. Additionally, when you send a message to a subscribed - list, mutt will add a Mail-Followup-To header to tell other users' mail user - agents not to send copies of replies to your personal address. Note that the - Mail-Followup-To header is a non-standard extension which is not supported by - all mail user agents. Adding it is not bullet-proof against receiving personal - CCs of list messages. Also note that the generation of the Mail-Followup-To - header is controlled by the _$_f_o_l_l_o_w_u_p___t_o (section 6.3.66 , page 80) configura- - tion variable. +From: Lucas User +Date: Thu, 02 Dec 2004 03:08:34 +0100 +To: Michael Random +Subject: Re: blackmail - 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''. +Pay me EUR 50,000.- cash or your favorite stuffed animal will die +a horrible death. - 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, +----- End forwarded message ----- - The Mutt-ng E-Mail Client 25 + 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. - for instance, you could say ``subscribe [0-9]*@bugs.guug.de''. Often, it's - sufficient to just give a portion of the list's e-mail address. + The 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. - Specify as much of the address as you need to to remove ambiguity. For exam- - ple, if you've subscribed to the Mutt-ng mailing list, you will receive mail - addressed to _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 ini- - tialization 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. + To the recipient, the bounced email will look as if he got it like a regular email where he was Bcc: recipient. The only possibility to find out whether it was a bounced email is to carefully study the email headers and to find out which host really sent the email. - The ``unlists'' command is used to remove a token from the list of known and - subscribed mailing-lists. Use ``unlists *'' to remove all tokens. +8. Postponing Mail - To remove a mailing list from the list of subscribed mailing lists, but keep it - on the list of known mailing lists, use ``unsubscribe''. + 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. - _3_._1_1 _U_s_i_n_g _M_u_l_t_i_p_l_e _s_p_o_o_l _m_a_i_l_b_o_x_e_s + 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. - Usage: mbox-hook [!]_p_a_t_t_e_r_n _m_a_i_l_b_o_x + 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. - This command is used to move read messages from a specified mailbox to a dif- - ferent 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. + See also the $postpone quad-option. - 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). +Chapter 3.

When Mutt-ng is first invoked, it will attempt to read the ``system'' configuration file (defaults set by your local system administrator), unless the ``-n'' commandline option is specified. This file is typically /usr/local/share/muttng/Muttngrc or /etc/Muttngrc , Mutt-ng users will find this file in /usr/local/share/muttng/Muttrc or /etc/Muttngrc. Mutt will next look for a file named .muttrc in your home directory, Mutt-ng will look for .muttngrc. If this file does not exist and your home directory has a subdirectory named .mutt , mutt try to load a file named .muttng/muttngrc. - Usage: + .muttrc (or .muttngrc for Mutt-ng) is the file where you will usually place your commands to configure Mutt-ng. - my_hdr _s_t_r_i_n_g +2.

The difference between the two types of quotes is similar to that of many popular shell programs, namely that a single quote is used to specify a literal string (one that is not interpreted for shell variables or quoting with a backslash (see next paragraph), while double quotes indicate a string for which should be evaluated. For example, backtics are evaluated inside of double quotes, but not for single quotes. - my_hdr Organization: A Really Big Company, Anytown, USA + \ 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" - in your .muttrc. + ``\\'' means to insert a literal ``\'' into the line. ``\n'' and ``\r'' have their usual C meanings of linefeed and carriage-return, respectively. - NNoottee:: space characters are _n_o_t allowed between the keyword and the colon - (``:''). The standard for electronic mail (RFC822) says that space is illegal - there, so Mutt-ng enforces the rule. + 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. - If you would like to add a header field to a single message, you should either - set the _e_d_i_t___h_e_a_d_e_r_s (section 6.3.54 , page 77) 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. + Please note that, unlike the various shells, mutt-ng interprets a ``\'' at the end of a line also in comments. This allows you to disable a command split over multiple lines with only one ``#''. +# folder-hook . \ +set realname="Michael \"MuttDude\" Elkins" - 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.

Environment Variables - This command is used to override the default filename used when saving mes- - sages. _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. + UNIX environments can be accessed like the way it is done in shells like sh and bash: Prepend the name of the environment by a ``$'' sign. For example, +set record=+sent_on_$HOSTNAME - See _M_e_s_s_a_g_e _M_a_t_c_h_i_n_g _i_n _H_o_o_k_s (section 4.4.1 , page 41) for information on the - exact format of _p_a_t_t_e_r_n. + sets the $record variable to the string +sent_on_ and appends the value of the evironment variable $HOSTNAME. - Examples: + Note: There will be no warning if an environment variable is not defined. The result will of the expansion will then be empty. - save-hook me@(turing\\.)?cs\\.hmc\\.edu$ +elkins - save-hook aol\\.com$ +spam +3.3. Configuration Variables - Also see the _f_c_c_-_s_a_v_e_-_h_o_o_k (section 3.17 , page 27) command. + As for environment variables, the values of all configuration variables as string can be used in the same way, too. For example, +set imap_home_namespace = $folder - _3_._1_6 _S_p_e_c_i_f_y _d_e_f_a_u_l_t _F_c_c_: _m_a_i_l_b_o_x _w_h_e_n _c_o_m_p_o_s_i_n_g + would set the value of $imap_home_namespace to the value to which $folder is currently set to. - Usage: fcc-hook [!]_p_a_t_t_e_r_n _m_a_i_l_b_o_x + Note: There're no logical links established in such cases so that the the value for $imap_home_namespace won't change even if $folder gets changed. - This command is used to save outgoing mail in a mailbox other than _$_r_e_c_o_r_d - (section 6.3.230 , page 120). Mutt-ng searches the initial list of message - recipients for the first matching _r_e_g_e_x_p and uses _m_a_i_l_b_o_x as the default Fcc: - mailbox. If no match is found the message will be saved to _$_r_e_c_o_r_d (section - 6.3.230 , page 120) mailbox. + Note: There will be no warning if a configuration variable is not defined or is empty. The result will of the expansion will then be empty. - See _M_e_s_s_a_g_e _M_a_t_c_h_i_n_g _i_n _H_o_o_k_s (section 4.4.1 , page 41) for information on the - exact format of _p_a_t_t_e_r_n. +3.4. Self-Defined Variables - Example: fcc-hook [@.]aol\\.com$ +spammers + 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. - The above will save a copy of all messages going to the aol.com domain to the - `+spammers' mailbox by default. Also see the _f_c_c_-_s_a_v_e_-_h_o_o_k (section 3.17 , - page 27) command. + For example, to view the manual, users can either define two macros like the following +macro generic "!less -r /path/to/manual" "Show manual" +macro pager "!less -r /path/to/manual" "Show manual" - _3_._1_7 _S_p_e_c_i_f_y _d_e_f_a_u_l_t _s_a_v_e _f_i_l_e_n_a_m_e _a_n_d _d_e_f_a_u_l_t _F_c_c_: _m_a_i_l_b_o_x _a_t _o_n_c_e + for generic, pager and index .The alternative is to define a custom variable like so: +set user_manualcmd = "!less -r /path/to_manual" +macro generic "$user_manualcmd" "Show manual" +macro pager "$user_manualcmd" "Show manual" +macro index "$user_manualcmd" "Show manual" - Usage: fcc-save-hook [!]_p_a_t_t_e_r_n _m_a_i_l_b_o_x + to re-use the command sequence as in: +macro index "$user_manualcmd | grep '\^[ ]\\+~. '" "Show Patterns" - This command is a shortcut, equivalent to doing both a _f_c_c_-_h_o_o_k (section - 3.16 , page 27) and a _s_a_v_e_-_h_o_o_k (section 3.15 , page 26) with its arguments. + 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. - _3_._1_8 _C_h_a_n_g_e _s_e_t_t_i_n_g_s _b_a_s_e_d _u_p_o_n _m_e_s_s_a_g_e _r_e_c_i_p_i_e_n_t_s + 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. - Usage: reply-hook [!]_p_a_t_t_e_r_n _c_o_m_m_a_n_d + The complete removal is done via the unset keyword. - The Mutt-ng E-Mail Client 28 + After the following sequence: +set user_foo = 42 +set user_foo = 666 - Usage: send-hook [!]_p_a_t_t_e_r_n _c_o_m_m_a_n_d + the variable $user_foo has a current value of 666 and an initial of 42. The query +set ?user_foo - Usage: send2-hook [!]_p_a_t_t_e_r_n _c_o_m_m_a_n_d + will show 666. After doing the reset via +reset user_foo - These commands can be used to execute arbitrary configuration commands based - upon recipients of the message. _p_a_t_t_e_r_n is a regular expression matching the - desired address. _c_o_m_m_a_n_d is executed when _r_e_g_e_x_p matches recipients of the - message. + a following query will give 42 as the result. After unsetting it via +unset user_foo - reply-hook is matched against the message you are _r_e_p_l_y_i_n_g ttoo, instead of the - message you are _s_e_n_d_i_n_g. send-hook is matched against all messages, both _n_e_w - and _r_e_p_l_i_e_s. NNoottee:: reply-hooks are matched bbeeffoorree the send-hook, rreeggaarrddlleessss of - the order specified in the users's configuration file. + any query or operation (except the noted expansion within other statements) will lead to an error message. - send2-hook is matched every time a message is changed, either by editing it, or - by using the compose menu to change its recipients or subject. send2-hook is - executed after send-hook, and can, e.g., be used to set parameters such as the - _$_s_e_n_d_m_a_i_l (section 6.3.247 , page 124) variable depending on the message's - sender address. +3.5. Pre-Defined Variables - 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). + 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. - See _M_e_s_s_a_g_e _M_a_t_c_h_i_n_g _i_n _H_o_o_k_s (section 4.4.1 , page 41) for information on the - exact format of _p_a_t_t_e_r_n. + Please consult the local copy of your manual for their values as they may differ from different manual sources. Where the manual is installed in can be queried (already using such a variable) by running: +muttng -Q muttng_docdir - Example: send-hook mutt 'set mime_forward signature=''' + To extend the example for viewing the manual via self-defined variables, it can be made more readable and more portable by changing the real path in: +set user_manualcmd = '!less -r /path/to_manual' - Another typical use for this command is to change the values of the _$_a_t_t_r_i_b_u_- - _t_i_o_n (section 6.3.15 , page 68), _$_s_i_g_n_a_t_u_r_e (section 6.3.259 , page 127) and - _$_l_o_c_a_l_e (section 6.3.114 , page 93) variables in order to change the language - of the attributions and signatures based upon the recipients. + to: +set user_manualcmd = "!less -r $muttng_docdir/manual.txt" - NNoottee:: the send-hook's are only executed ONCE after getting the initial list of - recipients. Adding a recipient after replying or editing the message will NOT - cause any send-hook to be executed. Also note that my_hdr commands which mod- - ify recipient headers, or the message's subject, don't have any effect on the - current message when executed from a send-hook. + which works everywhere if a manual is installed. - _3_._1_9 _C_h_a_n_g_e _s_e_t_t_i_n_g_s _b_e_f_o_r_e _f_o_r_m_a_t_t_i_n_g _a _m_e_s_s_a_g_e + 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. - Usage: message-hook [!]_p_a_t_t_e_r_n _c_o_m_m_a_n_d + For example, the statement +folder-hook . "set user_current_folder = $muttng_folder_name" - 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 mul- - tiple matches occur, commands are executed in the order they are specified in - the muttrc. + will be already be translated to the following when reading the startup files: +folder-hook . "set user_current_folder = some_folder" - See _M_e_s_s_a_g_e _M_a_t_c_h_i_n_g _i_n _H_o_o_k_s (section 4.4.1 , page 41) for information on the - exact format of _p_a_t_t_e_r_n. + with some_folder being the name of the first folder muttng opens. On the contrary, +folder-hook . 'set user_current_folder = $muttng_folder_name' - Example: + will be executed at runtime because of the single quotes so that user_current_folder will always have the value of the currently opened folder. - The Mutt-ng E-Mail Client 29 + A more practical example is: +folder-hook . 'source ~/.mutt/score-$muttng_folder_name' - message-hook ~A 'set pager=builtin' - message-hook '~f freshmeat-news' 'set pager="less \"+/^ subject: .*\""' + which can be used to source files containing score commands depending on the folder the user enters. - _3_._2_0 _C_h_o_o_s_i_n_g _t_h_e _c_r_y_p_t_o_g_r_a_p_h_i_c _k_e_y _o_f _t_h_e _r_e_c_i_p_i_e_n_t +3.6. Type Conversions - Usage: crypt-hook _p_a_t_t_e_r_n _k_e_y_i_d + 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 - When encrypting messages with PGP or OpenSSL, you may want to associate a cer- - tain key with a given e-mail address automatically, either because the recipi- - ent's public key can't be deduced from the destination address, or because, for - some reasons, you need to override the key Mutt-ng would normally use. The - crypt-hook command provides a method by which you can specify the ID of the - public key to be used when encrypting messages to a certain recipient. +4. Defining/Using aliases - 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. + Usage: aliaskey address [, address,...] - _3_._2_1 _A_d_d_i_n_g _k_e_y _s_e_q_u_e_n_c_e_s _t_o _t_h_e _k_e_y_b_o_a_r_d _b_u_f_f_e_r + 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. - Usage: push _s_t_r_i_n_g + 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 (``,''). - This command adds the named string to the keyboard buffer. The string may con- - tain control characters, key names and function names like the sequence string - in the _m_a_c_r_o (section 3.6 , page 20) command. You may use it to automatically - run a sequence of commands at startup, or when entering certain folders. + To remove an alias or aliases (``*'' means all aliases): - _3_._2_2 _E_x_e_c_u_t_i_n_g _f_u_n_c_t_i_o_n_s + unalias [* | key...] +alias muttdude me@cs.hmc.edu (Michael Elkins) +alias theguys manny, moe, jack - Usage: exec _f_u_n_c_t_i_o_n [ _f_u_n_c_t_i_o_n ... ] + 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. - This command can be used to execute any function. Functions are listed in the - _f_u_n_c_t_i_o_n _r_e_f_e_r_e_n_c_e (section 6.4 , page 147). ``exec function'' is equivalent - to ``push ''. + 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. - _3_._2_3 _M_e_s_s_a_g_e _S_c_o_r_i_n_g + For example: +source /usr/local/share/Mutt-ng.aliases +source ~/.mail_aliases +set alias_file=~/.mail_aliases - Usage: score _p_a_t_t_e_r_n _v_a_l_u_e + 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. - Usage: unscore _p_a_t_t_e_r_n [ _p_a_t_t_e_r_n ... ] + 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. - The score commands adds _v_a_l_u_e to a message's score if _p_a_t_t_e_r_n matches it. _p_a_t_- - _t_e_r_n is a string in the format described in the _p_a_t_t_e_r_n_s (section 4.2 , page - 36) section (note: For efficiency reasons, patterns which scan information not - available in the index, such as ~b, ~B or ~h, may not be used). _v_a_l_u_e is a - positive or negative integer. A message's final score is the sum total of all - matching score entries. However, you may optionally prefix _v_a_l_u_e with an equal - sign (=) to cause evaluation to stop at a particular entry if there is a match. - Negative final scores are rounded up to 0. + 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. - The unscore command removes score entries from the list. You mmuusstt specify the - same pattern specified in the score command for it to be removed. The pattern - ``*'' is a special token which means to clear the list of all score entries. +5. Changing the default key bindings - The Mutt-ng E-Mail Client 30 + Usage: bindmapkeyfunction - _3_._2_4 _S_p_a_m _d_e_t_e_c_t_i_o_n + This command allows you to change the default key bindings (operation invoked when pressing a key). - Usage: spam _p_a_t_t_e_r_n _f_o_r_m_a_t + 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: - Usage: nospam _p_a_t_t_e_r_n + 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 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 _$_i_n_d_e_x___f_o_r_m_a_t (section 6.3.110 , page 90) variable. - (Tip: try %?H?[%H] ? to display spam tags only when they are defined for a - given message.) + 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). - 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. + attach + The attachment menu is used to access the attachments on received messages. - 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 mes- - sage matches two or more of these patterns, and the $spam_separator variable is - set to a string, then the message's spam tag will consist of all the _f_o_r_m_a_t - strings joined together, with the value of $spam_separator separating them. + browser + The browser is used for both browsing the local directory structure, and for listing all of your incoming mailboxes. - For example, suppose I use DCC, SpamAssassin, and PureMessage. I might define - these spam settings: + editor + The editor is the line-based editor the user enters text data. - 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=", " + index + The index is the list of messages contained in a mailbox. - If I then received a message that DCC registered with ``many'' hits under the - ``Fuz2'' checksum, and that PureMessage registered with a 97% probability of - being spam, that message's spam tag would read 90+/DCC-Fuz2, 97/PM. (The four - characters before ``=many'' in a DCC report indicate the checksum used -- in - this case, ``Fuz2''.) + compose + The compose menu is the screen used when sending a new message. - If the $spam_separator variable is unset, then each spam pattern match super- - sedes the previous one. Instead of getting joined _f_o_r_m_a_t strings, you'll get - only the last one to match. + pager + The pager is the mode used to display message/attachment data, and help listings. - 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 sort- - ing by spam attribute will use as a sort key. + pgp + The pgp menu is used to select the OpenPGP keys used for encrypting outgoing messages. - The Mutt-ng E-Mail Client 31 + 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. - 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. + 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?). - 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 lower priority than - ``z''. Clearly, in general, sorting by spam tags is most effective when you can - coerce your filter to give you a raw number. But in case you can't, mutt can - still do something useful. + In addition, key may consist of: - The nospam command can be used to write exceptions to spam patterns. If a - header pattern matches something in a spam command, but you nonetheless do not - want it to receive a spam tag, you can list a more precise pattern under a - nospam command. + Table 3.1. Alternative Key Names + 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 - 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 exist- - ing spam list entry, the effect will be to remove the entry from the spam list, - instead of adding an exception. Likewise, if the _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 - folder-hook. + key does not need to be enclosed in quotes unless it contains a space (`` ''). - 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: + function specifies which action to take when key is pressed. For a complete list of functions, see the functions .The special function noop unbinds the specified key sequence. - spam "^From: .*MAILER-DAEMON" "999" +6. Defining aliases for character sets - _3_._2_5 _S_e_t_t_i_n_g _v_a_r_i_a_b_l_e_s + Usage: charset-hookalias charset + Usage: iconv-hookcharset local-charset - Usage: set [no|inv]_v_a_r_i_a_b_l_e[=_v_a_l_u_e] [ _v_a_r_i_a_b_l_e ... ] + The charset-hook command defines an alias for a character set. This is useful to properly display messages which are tagged with a character set name not known to mutt. - Usage: toggle _v_a_r_i_a_b_l_e [_v_a_r_i_a_b_l_e ... ] + 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. - Usage: unset _v_a_r_i_a_b_l_e [_v_a_r_i_a_b_l_e ... ] +7. Setting variables based upon mailbox - Usage: reset _v_a_r_i_a_b_l_e [_v_a_r_i_a_b_l_e ... ] + Usage: folder-hook [!]regexpcommand - This command is used to set (and unset) _c_o_n_f_i_g_u_r_a_t_i_o_n _v_a_r_i_a_b_l_e_s (section 6.3 , - page 65). There are four basic types of variables: boolean, number, string and - quadoption. _b_o_o_l_e_a_n variables can be _s_e_t (true) or _u_n_s_e_t (false). _n_u_m_b_e_r - variables can be assigned a positive integer value. + 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. - _s_t_r_i_n_g variables consist of any number of printable characters. _s_t_r_i_n_g_s must - be enclosed in quotes if they contain spaces or tabs. You may also use the - ``C'' escape sequences \\nn and \\tt for newline and tab, respectively. + 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. - The Mutt-ng E-Mail Client 32 + 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: +folder-hook mutt set sort=threads - _q_u_a_d_o_p_t_i_o_n variables are used to control whether or not to be prompted for cer- - tain actions, or to specify a default action. A value of _y_e_s will cause the - action to be carried out automatically as if you had answered yes to the ques- - tion. Similarly, a value of _n_o will cause the the action to be carried out as - if you had answered ``no.'' A value of _a_s_k_-_y_e_s will cause a prompt with a - default answer of ``yes'' and _a_s_k_-_n_o will provide a default answer of ``no.'' + However, the sorting method is not restored to its previous value when reading a different mailbox. To specify a default command, use the pattern ``.'': +folder-hook . set sort=date-sent - Prefixing a variable with ``no'' will unset it. Example: set noaskbcc. +8. Keyboard macros - For _b_o_o_l_e_a_n variables, you may optionally prefix the variable name with inv to - toggle the value (on or off). This is useful when writing macros. Example: - set invsmart_wrap. + Usage: macromenu keysequence [description] - The toggle command automatically prepends the inv prefix to all specified vari- - ables. + 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. - The unset command automatically prepends the no prefix to all specified vari- - ables. + 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. - Using the enter-command function in the _i_n_d_e_x menu, you can query the value of - a variable by prefixing the name of the variable with a question mark: + key and sequence are expanded by the same rules as the bind. There are some additions however. The first is that control characters in sequence can also be specified as ^x. In order to get a caret (`^'') you need to use ^^. Secondly, to specify a certain key such as up or to invoke a function directly, you can use the format and .For a listing of key names see the section on bind. Functions are listed in the functions. - set ?allow_8bit + 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). - The question mark is actually only required for boolean and quadoption vari- - ables. + Optionally you can specify a descriptive text after sequence, which is shown in the help screens. - The reset command resets all given variables to the compile time defaults - (hopefully mentioned in this manual). If you use the command set and prefix the - variable with ``&'' this has the same behavior as the reset command. + Note: Macro definitions (if any) listed in the help screen(s), are silently truncated at the screen width, and are not wrapped. - With the reset command there exists the special variable ``all'', which allows - you to reset all variables to their system defaults. +9.

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). - This command allows the inclusion of initialization commands from other files. - For example, I place all of my aliases in ~/.mail_aliases so that I can make my - ~/.muttrc readable and keep my aliases private. + object can be one of: + * attachment + * body (match regexp in the body of messages) + * bold (highlighting bold patterns in the body of messages) + * error (error messages printed by Mutt-ng) + * header (match regexp in the message header) + * hdrdefault (default color of the message header in the pager) + * index (match pattern 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 $quote_regexp in the body of a message) + * quoted1, quoted2, ..., quotedN (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) - If the filename begins with a tilde (``~''), it will be expanded to the path of - your home directory. + foreground and background can be one of the following: + * white + * black + * green + * magenta + * blue + * cyan + * yellow + * red + * default + * colorx - If the filename ends with a vertical bar (|), then _f_i_l_e_n_a_m_e is considered to be - an executable program from which to read input (eg. source ~/bin/myscript|). + foreground can optionally be prefixed with the keyword bright to make the foreground color boldfaced (e.g., brightred). - _3_._2_7 _C_o_n_f_i_g_u_r_i_n_g _f_e_a_t_u_r_e_s _c_o_n_d_i_t_i_o_n_a_l_l_y + 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): +set COLORFGBG="green;black" +export COLORFGBG - Usage: ifdef _i_t_e_m _c_o_m_m_a_n_d + Note: The S-Lang library requires you to use the lightgray and brown keywords instead of white and yellow when setting this variable. - The Mutt-ng E-Mail Client 33 + 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. - Usage: ifndef _i_t_e_m _c_o_m_m_a_n_d + 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. - These commands allow testing for a variable, function or certain feature being - available or not respectively, before actually executing the command given. + If your terminal does not support color, it is still possible change the video attributes through the use of the ``mono'' command: - ifdef (short for ``if defined'') only executes the command upon availability - while ifndef (short for ``if not defined'') does if not.

This command allows you to specify header fields which you don't normally want to see. - To exit mutt-ng directly if no NNTP support is compiled in: + 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. - ifndef feature_nntp 'push q' - # or - # ifndef newsrc 'push q' - # or - # ... + 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''. - To only set the _$_i_m_a_p___m_a_i_l___c_h_e_c_k (section 6.3.99 , page 88) variable if the - system's mutt-ng is aware of it, use: + ``unignore *'' will remove all tokens from the ignore list. - ifdef imap_mail_check 'set imap_mail_check=500' + For example: +# 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: - _3_._2_8 _R_e_m_o_v_i_n_g _h_o_o_k_s +11. Alternative addresses - Usage: unhook [ * | _h_o_o_k_-_t_y_p_e ] + Usage: [un]alternatesregexp [regexp...] - This command permits you to flush hooks you have previously defined. You can - either remove all hooks by giving the ``*'' character as an argument, or you - can remove all hooks of a specific type by saying something like unhook send- - hook. + 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.) - _4_. _A_d_v_a_n_c_e_d _U_s_a_g_e + 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. - The Mutt-ng E-Mail Client 34 + 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. - _4_._1 _R_e_g_u_l_a_r _E_x_p_r_e_s_s_i_o_n_s + 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. - All string patterns in Mutt-ng including those in more complex _p_a_t_t_e_r_n_s (sec- - tion 4.2 , page 36) 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. +12. Format = Flowed - 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: ``\\''. +12.1. Introduction - 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. + 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. - 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 _S_y_n_t_a_x _o_f _I_n_i_t_i_a_l_i_z_a_t_i_o_n _F_i_l_e_s (section 3.1 , page 14) for more informa- - tion on ' and ' delimiter processing. To match a literal ' or ' you must pref- - ace it with \ (backslash). + For introductory information on format=flowed messages, see . - 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. +12.2. Receiving: Display Setup - The period ``.'' matches any single character. The caret ``^'' and the dollar - sign ``$'' are metacharacters that respectively match the empty string at the - beginning and end of a line. + When you receive emails that are marked as format=flowed messages, and is formatted correctly, mutt-ng will try to reformat the message to optimally fit on your terminal. If you want a fixed margin on the right side of your terminal, you can set the following: +set wrapmargin = 10 - 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 nnoott in the list. For example, the regular expression - [[00112233445566778899]] matches any single digit. A range of ASCII characters may be - specified by giving the first and last characters, separated by a hyphen ``-''. - Most metacharacters lose their special meaning inside lists. To include a lit- - eral ``]'' place it first in the list. Similarly, to include a literal ``^'' - place it anywhere but first. Finally, to include a literal hyphen ``-'' place - it last. + The code above makes the line break 10 columns before the right side of the terminal. - 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: + If your terminal is so wide that the lines are embarrassingly long, you can also set a maximum line length: +set max_line_length = 120 - [:alnum:] - Alphanumeric characters. + The example above will give you lines not longer than 120 characters. - [:alpha:] - Alphabetic characters. + When you view at format=flowed messages, you will often see the quoting hierarchy like in the following example: +>Bill, can you please send last month's progress report to Mr. +>Morgan? We also urgently need the cost estimation for the new +>production server that we want to set up before our customer's +>project will go live. - [:blank:] - Space or tab characters. + This obviously doesn't look very nice, and it makes it very hard to differentiate between text and quoting character. The solution is to configure mutt-ng to "stuff" the quoting: +set stuff_quoted - The Mutt-ng E-Mail Client 35 + This will lead to a nicer result that is easier to read: +> Bill, can you please send last month's progress report to Mr. +> Morgan? We also urgently need the cost estimation for the new +> production server that we want to set up before our customer's +> project will go live. - [:cntrl:] - Control characters. +12.3. Sending - [:digit:] - Numeric characters. + If you want mutt-ng to send emails with format=flowed set, you need to explicitly set it: +set text_flowed - [:graph:] - Characters that are both printable and visible. (A space is print- - able, but not visible, while an ``a'' is both.) + 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. - [:lower:] - Lower-case alphabetic characters. + Also note that format=flowed knows about ``space-stuffing'', that is, when sending messages, some kinds of lines have to be indented with a single space on the sending side. On the receiving side, the first space (if any) is removed. As a consequence and in addition to the above simple setting, please keep this in mind when making manual formattings within the editor. Also note that mutt-ng currently violates the standard (RfC 3676) as it does not space-stuff lines starting with: + * > This is not the quote character but a right angle used for other reasons + * From with a trailing space. + * just a space for formatting reasons - [:print:] - Printable characters (characters that are not control characters.) + Please make sure that you manually prepend a space to each of them. - [:punct:] - Punctuation characters (characters that are not letter, digits, - control characters, or space characters). +12.4. Additional Notes - [:space:] - Space characters (such as space, tab and formfeed, to name a few). + 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. - [:upper:] - Upper-case alphabetic characters. +13. Mailing lists - [:xdigit:] - Characters that are hexadecimal digits. + Usage: [un]listsregexp [regexp...] + Usage: [un]subscriberegexp [regexp...] - 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, [[[[::ddiiggiitt::]]]] is equivalent to [[00--99]]. + 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. - Two additional special sequences can appear in character lists. These apply to - non-ASCII character sets, which can have single symbols (called collating ele- - ments) that are represented with more than one character, as well as several - characters that are equivalent for collating or sorting purposes: + 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''. - Collating Symbols - A collating symbol is a multi-character collating element enclosed - in ``[.'' and ``.]''. For example, if ``ch'' is a collating ele- - ment, then [[[[..cchh..]]]] is a regexp that matches this collating ele- - ment, while [[cchh]] is a regexp that matches either ``c'' or ``h''. + 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. - Equivalence Classes - An equivalence class is a locale-specific name for a list of char- - acters that are equivalent. The name is enclosed in ``[='' and - ``=]''. For example, the name ``e'' might be used to represent all - of ``'' ``'' and ``e''. In this case, [[[[==ee==]]]] is a regexp that - matches any of ``'', ``'' and ``e''. + 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. - A regular expression matching a single character may be followed by one of sev- - eral repetition operators: + The ``unlists'' command is used to remove a token from the list of known and subscribed mailing-lists. Use ``unlists *'' to remove all tokens. - The Mutt-ng E-Mail Client 36 - - ? - The preceding item is optional and matched at most once. - - * - The preceding item will be matched zero or more times. - - + - The preceding item will be matched one or more times. - - {n} - The preceding item is matched exactly _n times. - - {n,} - The preceding item is matched _n or more times. - - {,m} - The preceding item is matched at most _m times. - - {n,m} - The preceding item is matched at least _n times, but no more than _m - times. - - Two regular expressions may be concatenated; the resulting regular expression - matches any string formed by concatenating two substrings that respectively - match the concatenated subexpressions. - - Two regular expressions may be joined by the infix operator ``|''; the result- - ing regular expression matches any string matching either subexpression. - - 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. - - NNoottee:: If you compile Mutt-ng with the GNU _r_x package, the following operators - may also be used in regular expressions: - - \\y - Matches the empty string at either the beginning or the end of a - word. - - \\B - Matches the empty string within a word. - - \\< - Matches the empty string at the beginning of a word. - - \\> - Matches the empty string at the end of a word. - - \\w - Matches any word-constituent character (letter, digit, or under- - score). - - The Mutt-ng E-Mail Client 37 - - \\W - Matches any character that is not word-constituent. + To remove a mailing list from the list of subscribed mailing lists, but keep it on the list of known mailing lists, use ``unsubscribe''. - \\` - Matches the empty string at the beginning of a buffer (string). - - \\' - Matches the empty string at the end of a buffer. +14. Using Multiple spool mailboxes - 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. - - _4_._2 _P_a_t_t_e_r_n_s + Usage: mbox-hook [!]patternmailbox - Many of Mutt-ng's commands allow you to specify a pattern to match (limit, tag- - pattern, delete-pattern, etc.). There are several ways to select messages: + 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. - The Mutt-ng E-Mail Client 38 - - ~A all messages - ~b EXPR messages which contain EXPR in the message body - ~B EXPR messages which contain EXPR in the whole message - ~c USER messages carbon-copied to USER - ~C EXPR message is either to: or cc: EXPR - ~D deleted messages - ~d [MIN]-[MAX] messages with ``date-sent'' in a Date range - ~E expired messages - ~e EXPR message which contains EXPR in the ``Sender'' field - ~F flagged messages - ~f USER messages originating from USER - ~g cryptographically signed messages - ~G cryptographically encrypted messages - ~H EXPR messages with a spam attribute matching EXPR - ~h EXPR messages which contain EXPR in the message header - ~k message contains PGP key material - ~i ID message which match ID in the ``Message-ID'' field - ~L EXPR message is either originated or received by EXPR - ~l message is addressed to a known mailing list - ~m [MIN]-[MAX] message in the range MIN to MAX *) - ~n [MIN]-[MAX] messages with a score in the range MIN to MAX *) - ~N new messages - ~O old messages - ~p message is addressed to you (consults alternates) - ~P message is from you (consults alternates) - ~Q messages which have been replied to - ~R read messages - ~r [MIN]-[MAX] messages with ``date-received'' in a Date range - ~S superseded messages - ~s SUBJECT messages having SUBJECT in the ``Subject'' field. - ~T tagged messages - ~t USER messages addressed to USER - ~U unread messages - ~v message is part of a collapsed thread. - ~V cryptographically verified messages - ~w EXPR messages which contain EXPR in the `Newsgroups' field - (if compiled with NNTP support) - ~x EXPR messages which contain EXPR in the `References' field - ~y EXPR messages which contain EXPR in the `X-Label' field - ~z [MIN]-[MAX] messages with a size in the range MIN to MAX *) - ~= duplicated messages (see $duplicate_threads) - ~$ unreferenced messages (requires threaded view) - ~* ``From'' contains realname and (syntactically) valid - address (excluded are addresses matching against - alternates or any alias) + 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). - Where EXPR, USER, ID, and SUBJECT are _r_e_g_u_l_a_r _e_x_p_r_e_s_s_i_o_n_s (section 4.1 , page - 33). Special attention has to be made when using regular expressions inside of - patterns. Specifically, Mutt-ng's parser for these patterns will strip one - level of backslash (\), which is normally used for quoting. If it is your - intention to use a backslash in the regular expression, you will need to use - two backslashes instead (\\). +15. Defining mailboxes which receive mail - The Mutt-ng E-Mail Client 39 + Usage: [un]mailboxes [!]filename [filename...] - *) The forms <[MAX], >[MIN], [MIN]- and -[MAX] are allowed, too. + 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. - _4_._2_._1 _P_a_t_t_e_r_n _M_o_d_i_f_i_e_r + When changing folders, pressing space will cycle through folders with new mail. - Note that patterns matching 'lists' of addresses (notably c,C,p,P and t) match - if there is at least one match in the whole list. If you want to make sure that - all elements of that list match, you need to prefix your pattern with ^. This - example matches all mails which only has recipients from Germany. + 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. - ^~C \.de$ + The ``unmailboxes'' command is used to remove a token from the list of folders which receive mail. Use ``unmailboxes *'' to remove all tokens. - _4_._2_._2 _C_o_m_p_l_e_x _P_a_t_t_e_r_n_s + 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. - Logical AND is performed by specifying more than one criterion. For example: + 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. - ~t mutt ~f elkins +16. User defined headers - would select messages which contain the word ``mutt'' in the list of recipients - aanndd that have the word ``elkins'' in the ``From'' header field. + Usage: my_hdrstring + Usage: unmy_hdrfield [field...] - Mutt-ng also recognizes the following operators to create more complex search - patterns: + The ``my_hdr'' command allows you to create your own header fields which will be added to every message you send. - +o ! -- logical NOT operator + For example, if you would like to add an ``Organization:'' header field to all of your outgoing messages, you can put the command +my_hdr Organization: A Really Big Company, Anytown, USA - +o | -- logical OR operator + in your .muttrc. - +o () -- logical grouping operator + Note: space characters are not allowed between the keyword and the colon (``:''). The standard for electronic mail (RFC822) says that space is illegal there, so Mutt-ng enforces the rule. - Here is an example illustrating a complex search pattern. This pattern will - select all messages which do not contain ``mutt'' in the ``To'' or ``Cc'' field - and which are from ``elkins''. + If you would like to add a header field to a single message, you should either set the $edit_headers variable, or use the edit-headers function (default: ``E'') in the send-menu so that you can edit the header of your message along with the body. - !(~t mutt|~c mutt) ~f elkins + To remove user defined header fields, use the ``unmy_hdr'' command. You may specify an asterisk (``*'') to remove all header fields, or the fields to remove. For example, to remove all ``To'' and ``Cc'' header fields, you could use: +unmy_hdr to cc - Here is an example using white space in the regular expression (note the ' and - ' delimiters).

An example might be to save messages to a - mailing list to a separate folder, or to delete all messages with a given sub- - ject. To tag all messages matching a pattern, use the tag-pattern function, - which is bound to ``shift-T'' by default. Or you can select individual mes- - sages by hand using the ``tag-message'' function, which is bound to ``t'' by - default. See _p_a_t_t_e_r_n_s (section 4.2 , page 36) for Mutt-ng's pattern matching - syntax. + 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). - Once you have tagged the desired messages, you can use the ``tag-prefix'' oper- - ator, which is the ``;'' (semicolon) key by default. When the ``tag-prefix'' - operator is used, the nneexxtt operation will be applied to all tagged messages if - that operation can be used in that manner.

But in dealing with - messages a finer grain of control is needed for matching since for different - purposes you want to match different criteria. +25. Executing functions - Mutt-ng allows the use of the _s_e_a_r_c_h _p_a_t_t_e_r_n (section 4.2 , page 36) 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.). + Usage: execfunction [function...] - For example, if you wanted to set your return address based upon sending mail - to a specific address, you could do something like: + This command can be used to execute any function.

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 _$_d_e_f_a_u_l_t___h_o_o_k (section - 6.3.45 , page 75) variable. The pattern is translated at the time the hook is - declared, so the value of _$_d_e_f_a_u_l_t___h_o_o_k (section 6.3.45 , page 75) that is in - effect at that time will be used. + 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 Mutt-ng E-Mail Client 43 + When you use scoring, every message has a base score of 0. You can then use the score command to define patterns and a positive or negative value associated with it. When a pattern matches a message, the message's score will be raised or lowered by the amount of the value associated with the pattern. +score "~f/=f nion@muttng\.org" 50 +score "~f/=f @sco\.com" -100 - _4_._5 _U_s_i_n_g _t_h_e _s_i_d_e_b_a_r + If the pattern matches, it is also possible to set the score value of the current message to a certain value and then stop evaluation: +score "~f/=f santaclaus@northpole\.int" =666 - The sidebar, a feature specific to Mutt-ng, allows you to use a mailbox listing - which looks very similar to the ones you probably know from GUI mail clients. - The sidebar lists all specified mailboxes, shows the number in each and high- - lights the ones with new email Use the following configuration commands: + What is important to note is that negative score values will be rounded up to 0. - set sidebar_visible="yes" - set sidebar_width=25 + To make scoring actually useful, the score must be applied in some way. That's what the score thresholds are for. Currently, there are three score thresholds: + * flag threshold: when a message has a score value equal or higher than the flag threshold, it will be flagged. + * read threshold: when a message has a score value equal or lower than the read threshold, it will be marked as read. + * delete threshold: when a message has a score value equal or lower than the delete threshold, it will be marked as deleted. - If you want to specify the mailboxes you can do so with: + These three thresholds can be set via the variables $score_threshold_read, $score_threshold_flag and $score_threshold_delete. - set mbox='=INBOX' - mailboxes INBOX \ - MBOX1 \ - MBOX2 \ - ... + By default, $score_threshold_read and $score_threshold_delete are set to -1, which means that in the default threshold configuration no message will ever get marked as read or deleted. - You can also specify the colors for mailboxes with new mails by using: + Scoring gets especially interesting when combined with the color command and the ~n/=n pattern: +color index black yellow "~n/=n 10-" +color index red yellow "~n/=n 100-" - color sidebar_new red black - color sidebar white black + 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. - The available functions are: +27.

By defining your spam patterns with the spam and nospam commands, you can limit, search, and sort your mail based on its spam attributes, as determined by the external filter. You also can display the spam attributes in your index display using the %H selector in the $index_format variable. (Tip: try %?H?[%H] ? to display spam tags only when they are defined for a given message.) - 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 + Your first step is to define your external filter's spam patterns using the spam command. pattern should be a regular expression that matches a header in a mail message. If any message in the mailbox matches this regular expression, it will receive a ``spam tag'' or ``spam attribute'' (unless it also matches a nospam pattern -- see below.) The appearance of this attribute is entirely up to you, and is governed by the format parameter. format can be any static text, but it also can include back-references from the pattern expression. (A regular expression ``back-reference'' refers to a sub-expression contained within parentheses.) %1 is replaced with the first back-reference in the regex, %2 with the second, etc. - macro index B ':toggle sidebar_visible^M' - macro pager B ':toggle sidebar_visible^M' + If you're using multiple spam filters, a message can have more than one spam-related header. You can define spam patterns for each filter you use. If a message matches two or more of these patterns, and the $spam_separator variable is set to a string, then the message's spam tag will consist of all the format strings joined together, with the value of $spam_separator separating them. - 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'. + 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=", " - _4_._6 _E_x_t_e_r_n_a_l _A_d_d_r_e_s_s _Q_u_e_r_i_e_s + 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''.) - The Mutt-ng E-Mail Client 44 + If the $spam_separator variable is unset, then each spam pattern match supersedes the previous one. Instead of getting joined format strings, you'll get only the last one to match. - Mutt-ng supports connecting to external directory databases such as LDAP, - ph/qi, bbdb, or NIS through a wrapper script which connects to mutt using a - simple interface. Using the _$_q_u_e_r_y___c_o_m_m_a_n_d (section 6.3.221 , page 118) vari- - able, you specify the wrapper command to use. For example: + 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/=H pattern-matching expression matches against for search and limit functions. And it's what sorting by spam attribute will use as a sort key. - set query_command = "mutt_ldap_query.pl '%s'" + 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. - The wrapper script should accept the query on the command-line. It should - return a one line message, then each matching response on a single line, each - line containing a tab separated address then name then some other optional - information. On error, or if there are no matching addresses, return a non- - zero exit code and a one line error message. + Generally, when you sort by spam tag, mutt will sort lexically -- that is, by ordering strings alphnumerically. However, if a spam tag begins with a number, mutt will sort numerically first, and lexically only when two numbers are equal in value. (This is like UNIX's sort -n.) A message with no spam attributes at all -- that is, one that didn't match any of your spam patterns -- is sorted at lowest priority. Numbers are sorted next, beginning with 0 and ranging upward. Finally, non-numeric strings are sorted, with ``a'' taking 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. - An example multiple response output: + 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. - 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 + If the pattern given to nospam is exactly the same as the pattern on an existing spam list entry, the effect will be to remove the entry from the spam list, instead of adding an exception. Likewise, if the pattern for a spam command matches an entry on the nospam list, that nospam entry will be removed. If the pattern for nospam is ``*'', all entries on both lists will be removed. This might be the default action if you use spam and nospam in conjunction with a folder-hook. - There are two mechanisms for accessing the query function of mutt. One is to - do a query from the index menu using the query function (default: Q). This - will prompt for a query, then bring up the query menu which will list the - matching responses. From the query menu, you can select addresses to create - aliases, or to mail. You can tag multiple addresses to mail, start a new - query, or have a new query appended to the current responses. + 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" - The other mechanism for accessing the query function is for address completion, - similar to the alias completion. In any prompt for address entry, you can use - the complete-query function (default: ^T) to run a query based on the current - address you have typed. Like aliases, mutt will look for what you have typed - back to the last space or comma. If there is a single response for that query, - mutt will expand the address in place. If there are multiple responses, mutt - will activate the query menu. At the query menu, you can select one or more - addresses to be added to the prompt. +28.

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: + string variables consist of any number of printable characters. strings must be enclosed in quotes if they contain spaces or tabs. You may also use the ``C'' escape sequences \n and \t for newline and tab, respectively. - From me@cs.hmc.edu Fri, 11 Apr 1997 11:44:56 PST + quadoption variables are used to control whether or not to be prompted for certain actions, or to specify a default action. A value of yes will cause the action to be carried out automatically as if you had answered yes to the question. Similarly, a value of no will cause the the action to be carried out as if you had answered ``no.'' A value of ask-yes will cause a prompt with a default answer of ``yes'' and ask-no will provide a default answer of ``no.'' - The Mutt-ng E-Mail Client 45 + Prefixing a variable with ``no'' will unset it. Example: set noaskbcc . - to denote the start of a new message (this is often referred to as the - ``From_'' line). - - MMMMDDFF. 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). - - MMHH. 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 mes- - sage number (however, this is may not correspond to the message number Mutt-ng - displays). Deleted messages are renamed with a comma (,) prepended to the file- - name. NNoottee:: Mutt detects this type of mailbox by looking for either - .mh_sequences or .xmhcache (needed to distinguish normal directories from MH - mailboxes). - - MMaaiillddiirr. The newest of the mailbox formats, used by the Qmail MTA (a replace- - ment 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 two programs are writing the mailbox over NFS, - which means that no file locking is needed. - - _4_._8 _M_a_i_l_b_o_x _S_h_o_r_t_c_u_t_s - - 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. - - +o ! -- refers to your _$_s_p_o_o_l_f_i_l_e (section 6.3.295 , page 136) (incoming) - mailbox - - +o > -- refers to your _$_m_b_o_x (section 6.3.124 , page 95) file - - +o < -- refers to your _$_r_e_c_o_r_d (section 6.3.230 , page 120) file - - +o ^ -- refers to the current mailbox - - +o - or !! -- refers to the file you've last visited - - +o ~ -- refers to your home directory - - +o = or + -- refers to your _$_f_o_l_d_e_r (section 6.3.64 , page 79) directory - - +o @_a_l_i_a_s -- refers to the _d_e_f_a_u_l_t _s_a_v_e _f_o_l_d_e_r (section 3.15 , page 26) as - determined by the address of the alias - - _4_._9 _H_a_n_d_l_i_n_g _M_a_i_l_i_n_g _L_i_s_t_s - - Mutt-ng has a few configuration options that make dealing with large amounts of - mail easier. The first thing you must do is to let Mutt know what addresses - you consider to be mailing lists (technically this does not have to be a mail- - ing list, but that is what it is most often used for), and what lists you are - subscribed to. This is accomplished through the use of the _l_i_s_t_s _a_n_d _s_u_b_s_c_r_i_b_e - (section 3.10 , page 24) commands in your muttrc. - - Now that Mutt-ng knows what your mailing lists are, it can do several things, - - The Mutt-ng E-Mail Client 46 - - 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 mail- - box. In the _$_i_n_d_e_x___f_o_r_m_a_t (section 6.3.110 , page 90) variable, the escape - ``%L'' will return the string ``To '' when ``list'' appears in the ``To'' - field, and ``Cc '' when it appears in the ``Cc'' field (otherwise it - returns the name of the author). - - Often times the ``To'' and ``Cc'' fields in mailing list messages tend to get - quite large. Most people do not bother to remove the author of the message they - are reply to from the list, resulting in two or more copies being sent to that - person. The ``list-reply'' function, which by default is bound to ``L'' in the - _i_n_d_e_x menu and _p_a_g_e_r, helps reduce the clutter by only replying to the known - mailing list addresses instead of all recipients (except as specified by Mail- - Followup-To, see below). - - Mutt-ng also supports the Mail-Followup-To header. When you send a message to - a list of recipients which includes one or several subscribed mailing lists, - and if the _$_f_o_l_l_o_w_u_p___t_o (section 6.3.66 , page 80) 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 _$_h_o_n_o_r___f_o_l_l_o_w_u_p___t_o - (section 6.3.88 , page 85) configuration variable is set. Using list-reply - will in this case also make sure that the reply goes to the mailing list, even - if it's not specified in the list of recipients in the Mail-Followup-To. - - Note that, when header editing is enabled, you can create a Mail-Followup-To - header manually. Mutt-ng will only auto-generate this header if it doesn't - exist when you send the message. - - The other method some mailing list admins use is to generate a ``Reply-To'' - field which points back to the mailing list address rather than the author of - the message. This can create problems when trying to reply directly to the - author in private, since most mail clients will automatically reply to the - address given in the ``Reply-To'' field. Mutt-ng uses the _$_r_e_p_l_y___t_o (section - 6.3.233 , page 121) 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 in the ``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. - - The ``X-Label:'' header field can be used to further identify mailing lists or - list subject matter (or just to annotate messages individually). The - _$_i_n_d_e_x___f_o_r_m_a_t (section 6.3.110 , page 90) 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 eas- - ily be inserted by procmail and other mail filtering agents. - - The Mutt-ng E-Mail Client 47 - - Lastly, Mutt-ng has the ability to _s_o_r_t (section 6.3.289 , page 134) the mail- - box into _t_h_r_e_a_d_s (section 2.3.3 , page 7). A thread is a group of messages - which all relate to the same subject. This is usually organized into a tree- - like structure where a message and all of its replies are represented graphi- - cally. If you've ever used a threaded news client, this is the same concept. - It makes dealing with large volume mailing lists easier because you can easily - delete uninteresting threads and quickly find topics of value. - - _4_._1_0 _E_d_i_t_i_n_g _t_h_r_e_a_d_s - - 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. - - _4_._1_0_._1 _L_i_n_k_i_n_g _t_h_r_e_a_d_s - - Some mailers tend to "forget" to correctly set the "In-Reply-To:" and "Refer- - ences:" headers when replying to a message. This results in broken discussions - because Mutt-ng has not enough information to guess the correct threading. You - can fix this by tagging the reply, then moving to the parent message and using - the ``link-threads'' function (bound to & by default). The reply will then be - connected to this "parent" message. - - You can also connect multiple children at once, tagging them and using the tag- - prefix command (';') or the auto_tag option. - - _4_._1_0_._2 _B_r_e_a_k_i_n_g _t_h_r_e_a_d_s - - On mailing lists, some people are in the bad habit of starting a new discussion - by hitting "reply" to any message from the list and changing the subject to a - totally unrelated one. You can fix such threads by using the ``break-thread'' - function (bound by default to #), which will turn the subthread starting from - the current message into a whole different thread. - - _4_._1_1 _D_e_l_i_v_e_r_y _S_t_a_t_u_s _N_o_t_i_f_i_c_a_t_i_o_n _(_D_S_N_) _S_u_p_p_o_r_t - - RFC1894 defines a set of MIME content types for relaying information about the - status of electronic mail messages. These can be thought of as ``return - receipts.'' 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. - - To support this, there are two variables. _$_d_s_n___n_o_t_i_f_y (section 6.3.51 , page - 76) is used to request receipts for different results (such as failed message, - message delivered, etc.). _$_d_s_n___r_e_t_u_r_n (section 6.3.52 , page 76) requests how - much of your message should be returned with the receipt (headers or full mes- - sage). Refer to the man page on sendmail for more details on DSN. - - _4_._1_2 _P_O_P_3 _S_u_p_p_o_r_t _(_O_P_T_I_O_N_A_L_) - - If Mutt-ng was compiled with POP3 support (by running the _c_o_n_f_i_g_u_r_e script with - the _-_-_e_n_a_b_l_e_-_p_o_p flag), it has the ability to work with mailboxes located on a - remote POP3 server and fetch mail for local browsing. - - The Mutt-ng E-Mail Client 48 - - You can access the remote POP3 mailbox by selecting the folder - pop://popserver/. - - You can select an alternative port by specifying it with the server, i.e.: - pop://popserver:port/. - - You can also specify different username for each folder, i.e.: pop://user- - name@popserver[:port]/. - - Polling for new mail is more expensive over POP3 than locally. For this reason - the frequency at which Mutt-ng will check for mail remotely can be controlled - by the _$_p_o_p___m_a_i_l___c_h_e_c_k (section 6.3.208 , page 115) variable, which defaults - to every 60 seconds. - - 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 natu- - rally requires that the server supports SSL encrypted connections. To access a - folder with POP3/SSL, you should use pops: prefix, ie: pops://[user- - name@]popserver[:port]/. - - 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 _p_o_p___h_o_s_t (section 6.3.206 , page 115), fetch all your - new mail and place it in the local _s_p_o_o_l_f_i_l_e (section 6.3.295 , page 136). - After this point, Mutt-ng runs exactly as if the mail had always been local. - - NNoottee:: If you only need to fetch all messages to local mailbox you should con- - sider using a specialized program, such as fetchmail + For boolean variables, you may optionally prefix the variable name with inv to toggle the value (on or off). This is useful when writing macros. Example: set invsmart_wrap. - _4_._1_3 _I_M_A_P _S_u_p_p_o_r_t _(_O_P_T_I_O_N_A_L_) + The toggle command automatically prepends the inv prefix to all specified variables. - 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. + The unset command automatically prepends the no prefix to all specified variables. - You can access the remote inbox by selecting the folder - imap://imapserver/INBOX, where imapserver is the name of the IMAP server and - INBOX is the special name for your spool mailbox on the IMAP server. If you - want to access another mail folder at the IMAP server, you should use - imap://imapserver/path/to/folder where path/to/folder is the path of the folder - you want to access. + Using the enter-command function in the index menu, you can query the value of a variable by prefixing the name of the variable with a question mark: +set ?allow_8bit - You can select an alternative port by specifying it with the server, i.e.: - imap://imapserver:port/INBOX. + The question mark is actually only required for boolean and quadoption variables. - You can also specify different username for each folder, i.e.: imap://user- - name@imapserver[:port]/INBOX. + The reset command resets all given variables to the compile time defaults (hopefully mentioned in this manual). If you use the command set and prefix the variable with ``&'' this has the same behavior as the reset command. - 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 natu- - rally requires that the server supports SSL encrypted connections. To access a - folder with IMAP/SSL, you should use imaps://[user- - name@]imapserver[:port]/path/to/folder as your folder path. + With the reset command there exists the special variable ``all'', which allows you to reset all variables to their system defaults. - Pine-compatible notation is also supported, i.e. +29. Reading initialization commands from another file - The Mutt-ng E-Mail Client 49 + Usage: sourcefilename [filename...] - {[username@]imapserver[:port][/ssl]}path/to/folder + This command allows the inclusion of initialization commands from other files. For example, I place all of my aliases in ~/.mail_aliases so that I can make my ~/.muttrc readable and keep my aliases private. - Note that not all servers use / as the hierarchy separator. Mutt-ng should - correctly notice which separator is being used by the server and convert paths - accordingly. + If the filename begins with a tilde (``~''), it will be expanded to the path of your home directory. - 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 _$_i_m_a_p___l_i_s_t___s_u_b_s_c_r_i_b_e_d (section 6.3.97 , page 87) vari- - able. + If the filename ends with a vertical bar (|), then filename is considered to be an executable program from which to read input (eg. source ~/bin/myscript|). - Polling for new mail on an IMAP server can cause noticeable delays. So, you'll - want to carefully tune the _$_i_m_a_p___m_a_i_l___c_h_e_c_k (section 6.3.99 , page 88) and - _$_t_i_m_e_o_u_t (section 6.3.318 , page 142) variables. +30. Removing hooks - Note that if you are using mbox as the mail store on UW servers prior to - v12.250, the server has been reported to disconnect a client if another client - selects the same folder. + Usage: unhook [* | hook-type] - _4_._1_3_._1 _T_h_e _F_o_l_d_e_r _B_r_o_w_s_e_r + This command permits you to flush hooks you have previously defined. You can either remove all hooks by giving the ``*'' character as an argument, or you can remove all hooks of a specific type by saying something like unhook send. - 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: +31. Sharing Setups - +o Instead of file permissions, mutt displays the string "IMAP", possibly - followed by the symbol "+", indicating that the entry contains both mes- - sages and subfolders. On Cyrus-like servers folders will often contain - both messages and subfolders. +31.1. Character Sets - +o 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). + As users may run mutt-ng on different systems, the configuration must be maintained because it's likely that people want to use the setup everywhere they use mutt-ng. And mutt-ng tries to help where it can. - +o You can create, delete and rename mailboxes with the create-mailbox, - delete-mailbox, and rename-mailbox commands (default bindings: C, d and r, - respectively). You may also subscribe and unsubscribe to mailboxes (nor- - mally these are bound to s and u, respectively). + To not produce conflicts with different character sets, mutt-ng allows users to specify in which character set their configuration files are encoded. Please note that while reading the configuration files, this is only respected after the corresponding declaration appears. It's advised to put the following at the very beginning of a users muttngrc: +set config_charset = "..." - _4_._1_3_._2 _A_u_t_h_e_n_t_i_c_a_t_i_o_n + and replacing the dots with the actual character set. To avoid problems while maintaining the setup, vim(1) user's may want to use modelines as show in: +# vim:fileencoding=...: - Mutt-ng supports four authentication methods with IMAP servers: SASL, GSSAPI, - CRAM-MD5, and LOGIN (there is a patch by Grant Edwards to add NTLM authentica- - tion for you poor exchange users out there, but it has yet to be integrated - into the main tree). There is also support for the pseudo-protocol ANONYMOUS, - which allows you to log in to a public IMAP server without having an account. - To use ANONYMOUS, simply make your username blank or "anonymous". + while, again, replacing the dots with the appropriate name. This tells vim(1) as which character set to read and save the file. - SASL is a special super-authenticator, which selects among several protocols - (including GSSAPI, CRAM-MD5, ANONYMOUS, and DIGEST-MD5) the most secure method - available on your host and the server. Using some of these methods (including - DIGEST-MD5 and possibly GSSAPI), your entire session will be encrypted and - invisible to those teeming network snoops. It is the best option if you have - it. To use it, you must have the Cyrus SASL library installed on your system +31.2. Modularization - The Mutt-ng E-Mail Client 50 + ``Modularization'' means to divide the setup into several files while sorting the options or commands by topic. Especially for longer setups (e.g. with many hooks), this helps maintaining it and solving trouble. - and compile mutt with the _-_-_w_i_t_h_-_s_a_s_l flag. + When using separation, setups may be, as a whole or in fractions, shared over different systems. - Mutt-ng will try whichever methods are compiled in and available on the server, - in the following order: SASL, ANONYMOUS, GSSAPI, CRAM-MD5, LOGIN. +31.3. Conditional parts - There are a few variables which control authentication: + When using a configuration on different systems, the user may not always have influence on how mutt-ng is installed and which features it includes. - +o _$_i_m_a_p___u_s_e_r (section 6.3.105 , page 89) - controls the username under - which you request authentication on the IMAP server, for all authentica- - tors. This is overridden by an explicit username in the mailbox path (i.e. - by using a mailbox name of the form {user@host}). + To solve this, mutt-ng contain a feature based on the ``ifdef'' patch written for mutt. Its basic syntax is: +ifdef +ifndef - +o _$_i_m_a_p___p_a_s_s (section 6.3.100 , page 88) - a password which you may preset, - used by all authentication methods where a password is needed. + ...whereby can be one of: + * a function name + * a variable name + * a menu name + * a feature name - +o _$_i_m_a_p___a_u_t_h_e_n_t_i_c_a_t_o_r_s (section 6.3.91 , page 85) - 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). + All available functions, variables and menus are documented elsewhere in this manual but ``features'' is specific to these two commands. To test for one, prefix one of the following keywords with feature_: ncurses, slang, iconv, idn, dotlock, standalone, pop, nntp, imap, ssl, gnutls, sasl, sasl2, libesmtp, compressed, color, classic_pgp, classic_smime, gpgme, header_cache - _4_._1_4 _M_a_n_a_g_i_n_g _m_u_l_t_i_p_l_e _I_M_A_P_/_P_O_P _a_c_c_o_u_n_t_s _(_O_P_T_I_O_N_A_L_) + As an example, one can use the following in ~/.muttngrc: +ifdef feature_imap 'source ~/.mutt-ng/setup-imap' +ifdef feature_pop 'source ~/.mutt-ng/setup-pop' +ifdef feature_nntp 'source ~/.mutt-ng/setup-nntp' - If you happen to have accounts on multiple IMAP and/or POP servers, you may - find managing all the authentication settings inconvenient and error-prone. - The account-hook command may help. This hook works like folder-hook but is - invoked whenever you access a remote mailbox (including inside the folder - browser), not just when you open the mailbox. + ...to only source ~/.mutt-ng/setup-imap if IMAP support is built in, only source ~/.mutt-ng/setup-pop if POP support is built in and only source ~/.mutt-ng/setup-nntp if NNTP support is built in. - Some examples: + An example for testing for variable names can be used if users use different revisions of mutt-ng whereby the older one may not have a certain variable. To test for the availability of $imap_mail_check use: +ifdef imap_mail_check 'set imap_mail_check = 300' - 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"' + Provided for completeness is the test for menu names. To set $pager_index_lines only if the pager menu is available, use: +ifdef pager 'set pager_index_lines = 10' - _4_._1_5 _S_t_a_r_t _a _W_W_W _B_r_o_w_s_e_r _o_n _U_R_L_s _(_E_X_T_E_R_N_A_L_) + For completeness, too, the opposite of ifdef is provided: ifndef which only executes the command if the test fails. For example, the following two examples are equivalent: +ifdef feature_ncurses 'source ~/.mutt-ng/setup-ncurses' +ifndef feature_ncurses 'source ~/.mutt-ng/setup-slang' - 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 ftp://ftp.mutt.org/mutt/con- - trib/ and the configuration commands: + ...and... +ifdef feature_slang 'source ~/.mutt-ng/setup-slang' +ifndef feature_slang 'source ~/.mutt-ng/setup-ncurses' - macro index \cb |urlview\n - macro pager \cb |urlview\n +32.

Please see sect-obsolete for a complete list. - 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. +Chapter 4. Advanced Usage - The Mutt-ng E-Mail Client 51 + Table of Contents - The most common use is to open compressed archived folders e.g. with gzip. + 1. Regular Expressions + 2. Patterns - In addition, the user can provide a script that gets a folder in an accepted - format and appends its context to the folder in the user-defined format, which - may be faster than converting the entire folder to the accepted format, append- - ing to it and converting back to the user-defined format. + 2.1. Complex Patterns + 2.2. Patterns and Dates - There are three hooks defined (_o_p_e_n_-_h_o_o_k (section 4.16.1 , page 50), _c_l_o_s_e_- - _h_o_o_k (section 4.16.2 , page 51) and _a_p_p_e_n_d_-_h_o_o_k (section 4.16.3 , page 51)) - which define commands to uncompress and compress a folder and to append mes- - sages to an existing compressed folder respectively. + 3. Format Strings - For example: + 3.1. Introduction + 3.2. Conditional Expansion + 3.3. Modifications and Padding - open-hook \\.gz$ "gzip -cd %f > %t" - close-hook \\.gz$ "gzip -c %t > %f" - append-hook \\.gz$ "gzip -c %t >> %f" + 4. Using Tags + 5. Using Hooks - You do not have to specify all of the commands. If you omit _a_p_p_e_n_d_-_h_o_o_k (sec- - tion 4.16.3 , page 51), the folder will be open and closed again each time you - will add to it. If you omit _c_l_o_s_e_-_h_o_o_k (section 4.16.2 , page 51) (or give - empty command) , the folder will be open in the mode. If you specify _a_p_p_e_n_d_- - _h_o_o_k (section 4.16.3 , page 51) though you'll be able to append to the folder. + 5.1. Message Matching in Hooks - Note that Mutt-ng will only try to use hooks if the file is not in one of the - accepted formats. In particular, if the file is empty, mutt supposes it is not - compressed. This is important because it allows the use of programs that do not - have well defined extensions. Just use '.' as a regexp. But this may be sur- - prising if your compressing script produces empty files. In this situation, - unset _$_s_a_v_e___e_m_p_t_y (section 6.3.240 , page 123), so that the compressed file - will be removed if you delete all of the messages. + 6. Using the sidebar + 7.

Authentication - 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. + 15. NNTP Support (OPTIONAL) - %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. + 15.1. Again: Scoring - The _c_o_m_m_a_n_d should nnoott 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. + 16. SMTP Support (OPTIONAL) + 17. Managing multiple IMAP/POP/NNTP accounts (OPTIONAL) + 18.

Regular Expressions - open-hook \\.gz$ "gzip -cd %f > %t" + All string patterns in Mutt-ng including those in more complex patterns must be specified using regular expressions (regexp) in the ``POSIX extended'' syntax (which is more or less the syntax used by egrep and GNU awk). For your convenience, we have included below a brief description of this syntax. - If the _c_o_m_m_a_n_d is empty, this operation is disabled for this file type. + 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: ``\\''. - _4_._1_6_._2 _W_r_i_t_e _a _c_o_m_p_r_e_s_s_e_d _m_a_i_l_b_o_x + 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. - Usage: close-hook _r_e_g_e_x_p '_c_o_m_m_a_n_d' + Note that the regular expression can be enclosed/delimited by either " or ' which is useful if the regular expression includes a white-space character. See muttrc-syntax for more information on " and ' delimiter processing. To match a literal " or ' you must preface it with \ (backslash). - This is used to close the folder that was open with the _o_p_e_n_-_h_o_o_k (section - 4.16.1 , page 50) command after some changes were made to it. + 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. - 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 _o_p_e_n_-_h_o_o_k (section - 4.16.1 , page 50) command. Temporary folder in this case is the folder previ- - ously produced by the <_o_p_e_n_-_h_o_o_k (section 4.16.1 , page 50) command. + The period ``.'' matches any single character. The caret ``^'' andthe dollar sign ``$'' are metacharacters that respectively match the empty string at the beginning and end of a line. - The _c_o_m_m_a_n_d should nnoott remove the decompressed file. The _c_o_m_m_a_n_d should return - non-zero exit status if it fails, so mutt knows something's wrong. + A list of characters enclosed by ``]'' and ``['' matches any single character in that list; if the first character of the list is a caret ``^'' then it matches any character not in the list. For example, the regular expression ]0123456789[ matches any single digit. A range of ASCII characters may be specified by giving the first and last characters, separated by a hyphen ``-''. Most metacharacters lose their special meaning inside lists. To include a literal ``['' place it first in the list. Similarly, to include a literal ``^'' place it anywhere but first. Finally, to include a literal hyphen ``-'' place it last. - Example: + Certain named classes of characters are predefined. Character classes consist of ``]:'', a keyword denoting the class, and ``:[''. The following classes are defined by the POSIX standard: - close-hook \\.gz$ "gzip -c %t > %f" + ]:alnum:[ + Alphanumeric characters. - 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. + ]:alpha:[ + Alphabetic characters. - _c_l_o_s_e_-_h_o_o_k (section 4.16.2 , page 51) is not called when you exit from the - folder if the folder was not changed. + ]:blank:[ + Space or tab characters. - _4_._1_6_._3 _A_p_p_e_n_d _a _m_e_s_s_a_g_e _t_o _a _c_o_m_p_r_e_s_s_e_d _m_a_i_l_b_o_x + ]:cntrl:[ + Control characters. - Usage: append-hook _r_e_g_e_x_p '_c_o_m_m_a_n_d' + ]:digit:[ + Numeric characters. - 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 _o_p_e_n_-_h_o_o_k (section 4.16.1 , page 50) - command. The temporary folder in this case contains the messages that are - being appended. + ]:graph:[ + Characters that are both printable and visible. (A space is printable, but not visible, while an ``a'' is both.) - The _c_o_m_m_a_n_d should nnoott 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. + ]:lower:[ + Lower-case alphabetic characters. - Example: + ]:print:[ + Printable characters (characters that are not control characters.) - append-hook \\.gz$ "gzip -c %t >> %f" + ]:punct:[ + Punctuation characters (characters that are not letter, digits, control characters, or space characters). - When _a_p_p_e_n_d_-_h_o_o_k (section 4.16.3 , page 51) 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 (_$_m_b_o_x___t_y_p_e (section 6.3.125 , page 95)) type is always + ]:space:[ + Space characters (such as space, tab and formfeed, to name a few). - The Mutt-ng E-Mail Client 53 + ]:upper:[ + Upper-case alphabetic characters. - supposed (i.e. this is the format used for the temporary folder). + ]:xdigit:[ + Characters that are hexadecimal digits. - If the file does not exist when you save to it, _c_l_o_s_e_-_h_o_o_k (section 4.16.2 , - page 51) is called, and not _a_p_p_e_n_d_-_h_o_o_k (section 4.16.3 , page 51). _a_p_p_e_n_d_- - _h_o_o_k (section 4.16.3 , page 51) is only for appending to existing folders. + A character class is only valid in a regular expression inside the brackets of a character list. Note that the brackets in these class names are part of the symbolic names, and must be included in addition to the brackets delimiting the bracket list. For example, ]]:digit:[[ is equivalent to ]0-9[. - 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 _o_p_e_n_-_h_o_o_k (section - 4.16.1 , page 50) and _c_l_o_s_e_-_h_o_o_k (section 4.16.2 , page 51)respectively) each - time you will add to it. + 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: - _4_._1_6_._4 _E_n_c_r_y_p_t_e_d _f_o_l_d_e_r_s + Collating Symbols + A collating symbol is a multi-character collating element enclosed in ``].'' and ``.[''. For example, if ``ch'' is a collating element, then ]].ch.[[ is a regexp that matches this collating element, while ]ch[ is a regexp that matches either ``c'' or ``h''. - The compressed folders support can also be used to handle encrypted folders. If - you want to encrypt a folder with PGP, you may want to use the following hooks: + 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''. - open-hook \\.pgp$ "pgp -f < %f > %t" - close-hook \\.pgp$ "pgp -fe YourPgpUserIdOrKeyId < %t > %f" + A regular expression matching a single character may be followed by one of several repetition operators: - Please note, that PGP does not support appending to an encrypted folder, so - there is no append-hook defined. + ? + The preceding item is optional and matched at most once. - NNoottee:: the folder is temporary stored decrypted in the /tmp directory, where it - can be read by your system administrator. So think about the security aspects - of this. + * + The preceding item will be matched zero or more times. - _5_. _M_u_t_t_-_n_g_'_s _M_I_M_E _S_u_p_p_o_r_t + + + The preceding item will be matched one or more times. - Quite a bit of effort has been made to make Mutt-ng the premier text-mode MIME - MUA. Every effort has been made to provide the functionality that the discern- - ing MIME user requires, and the conformance to the standards wherever possible. - When configuring Mutt-ng for MIME, there are two extra types of configuration - files which Mutt-ng uses. One is the mime.types file, which contains the map- - ping of file extensions to IANA MIME types. The other is the mailcap file, - which specifies the external commands to use for handling specific MIME types. + {n} + The preceding item is matched exactly n times. - _5_._1 _U_s_i_n_g _M_I_M_E _i_n _M_u_t_t + {n,} + The preceding item is matched n or more times. - 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. + {,m} + The preceding item is matched at most m times. - _5_._1_._1 _V_i_e_w_i_n_g _M_I_M_E _m_e_s_s_a_g_e_s _i_n _t_h_e _p_a_g_e_r + {n,m} + The preceding item is matched at least n times, but no more than m times. - When you select a message from the index and view it in the pager, Mutt decodes - the message to a text representation. Mutt-ng internally supports a number of - MIME types, including text/plain, text/enriched, message/rfc822, and mes- - sage/news. In addition, the export controlled version of Mutt-ng recognizes a - variety of PGP MIME types, including PGP/MIME and application/pgp. + Two regular expressions may be concatenated; the resulting regular expression matches any string formed by concatenating two substrings that respectively match the concatenated subexpressions. - Mutt-ng will denote attachments with a couple lines describing them. These - lines are of the form: + Two regular expressions may be joined by the infix operator ``|''; the resulting regular expression matches any string matching either subexpression. - The Mutt-ng E-Mail Client 54 + 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. - [-- Attachment #1: Description --] - [-- Type: text/plain, Encoding: 7bit, Size: 10000 --] + Note: If you compile Mutt-ng with the GNU rx package, the following operators may also be used in regular expressions: - Where the Description is the description or filename given for the attachment, - and the Encoding is one of 7bit/8bit/quoted-printable/base64/binary. + \\y + Matches the empty string at either the beginning or the end of a word. - If Mutt-ng cannot deal with a MIME type, it will display a message like: + \\B + Matches the empty string within a word. - [-- image/gif is unsupported (use 'v' to view this part) --] + \\< + Matches the empty string at the beginning of a word. - _5_._1_._2 _T_h_e _A_t_t_a_c_h_m_e_n_t _M_e_n_u + \\> + Matches the empty string at the end of a word. - The default binding for view-attachments is `v', which displays the attachment - menu for a message. The attachment menu displays a list of the attachments in - a message. From the attachment menu, you can save, print, pipe, delete, and - view attachments. You can apply these operations to a group of attachments at - once, by tagging the attachments and by using the ``tag-prefix'' operator. You - can also reply to the current message from this menu, and only the current - attachment (or the attachments tagged) will be quoted in your reply. You can - view attachments as text, or view them using the mailcap viewer definition. + \\w + Matches any word-constituent character (letter, digit, or underscore). - Finally, you can apply the usual message-related functions (like _r_e_s_e_n_d_-_m_e_s_s_a_g_e - (section 2.3.4 , page 9), and the reply and forward functions) to attachments - of type message/rfc822. + \\W + Matches any character that is not word-constituent. - See the help on the attachment menu for more information. + \\` + Matches the empty string at the beginning of a buffer (string). - _5_._1_._3 _T_h_e _C_o_m_p_o_s_e _M_e_n_u + \\' + Matches the empty string at the end of a buffer. - The compose menu is the menu you see before you send a message. It allows you - to edit the recipient list, the subject, and other aspects of your message. It - also contains a list of the attachments of your message, including the main - body. From this menu, you can print, copy, filter, pipe, edit, compose, - review, and rename an attachment or a list of tagged attachments. You can also - modifying the attachment information, notably the type, encoding and descrip- - tion. + 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. - Attachments appear as follows: +2.

A pattern consists of one or more sub-pattern, which can be logically grouped, ORed, and negated. For a complete listing of these patterns, please refer to table patterns in the Reference chapter. - 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 + 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. - The Mutt-ng E-Mail Client 55 +2.1. Complex Patterns - attachment, and can be changed with the edit-description command (default: d). + It is possible to combine several sub-patterns to a more complex pattern. The most simple possibility is to logically AND several patterns by stringing them together: +~s/=s 'SPAM' ~U/=U - _5_._2 _M_I_M_E _T_y_p_e _c_o_n_f_i_g_u_r_a_t_i_o_n _w_i_t_h _m_i_m_e_._t_y_p_e_s + The pattern above matches all messages that contain ``SPAM'' in the subject and are unread. - When you add an attachment to your mail message, Mutt-ng searches your personal - mime.types file at ${HOME}/.mime.types, and then the system mime.types file at - /usr/local/share/mutt/mime.types or /etc/mime.types + To logical OR patterns, simply use the | operator. This one especially useful when using local groups: +~f/=f ("nion@muttng\.org"|"ak@muttng\.org"|"pdmef@muttng\.org") +(~b/=b mutt-ng|~s/=s Mutt-ng) +!~x/=x '@synflood\.at' - The mime.types file consist of lines containing a MIME type and a space sepa- - rated list of extensions. For example: + 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. - application/postscript ps eps - application/pgp pgp - audio/x-aiff aif aifc aiff +2.2. Patterns and Dates - A sample mime.types file comes with the Mutt-ng distribution, and should con- - tain most of the MIME types you are likely to use. + When using dates in patterns, the dates must be specified in a special format, i.e. DD/MM/YYYY. If you don't specify month or year, they default to the current month or year. When using date ranges, and you specify only the minimum or the maximum, the specified date will be excluded, e.g. 01/06/2005- matches against all messages after Juni 1st, 2005. - If Mutt-ng can not determine the mime type by the extension of the file you - attach, it will look at the file. If the file is free of binary information, - Mutt-ng will assume that the file is plain text, and mark it as text/plain. If - the file contains binary information, then Mutt-ng will mark it as applica- - tion/octet-stream. You can change the MIME type that Mutt-ng assigns to an - attachment by using the edit-type command from the compose menu (default: ^T). - The MIME type is actually a major mime type followed by the sub-type, separated - by a '/'. 6 major types: application, text, image, video, audio, and model have - been approved after various internet discussions. Mutt-ng recognises all of - these if the appropriate entry is found in the mime.types file. It also recog- - nises other major mime types, such as the chemical type that is widely used in - the molecular modelling community to pass molecular data in various forms to - various molecular viewers. Non-recognised mime types should only be used if the - recipient of the message is likely to be expecting such attachments. + 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/=d 01/01/2005+1y +~d/=d 18/10/2004-2w +~d/=d 28/12/2004*1d - _5_._3 _M_I_M_E _V_i_e_w_e_r _c_o_n_f_i_g_u_r_a_t_i_o_n _w_i_t_h _m_a_i_l_c_a_p + 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). - Mutt-ng supports RFC 1524 MIME Configuration, in particular the Unix specific - format specified in Appendix A of RFC 1524. This file format is commonly - referred to as the mailcap format. Many MIME compliant programs utilize the - mailcap format, allowing you to specify handling for all MIME types in one - place for all programs. Programs known to use this format include Netscape, - XMosaic, lynx and metamail. + Relative dates are also very important, as they make it possible to specify date ranges between a fixed number of units and the current date. How this works can be seen in the following example: +~d/=d >2w # messages older than two weeks +~d/=d <3d # messages newer than 3 days +~d/=d =1m # messages that are exactly one month old - 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 +3. Format Strings - ${HOME}/.mailcap:/usr/local/share/mutt/mailcap:/etc/mailcap:/etc/mailcap:/usr/etc/mailcap:/usr/local/etc/mailcap +3.1. Introduction - where $HOME is your home directory. + The so called Format Strings offer great flexibility when configuring mutt-ng. In short, they describe what items to print out how in menus and status messages. - In particular, the metamail distribution will install a mailcap file, usually + Basically, they work as this: for different menus and bars, there's a variable specifying the layout. For every item available, there is a so called expando. - The Mutt-ng E-Mail Client 56 + For example, when running mutt-ng on different machines or different versions for testing purposes, it may be interesting to have the following information always printed on screen when one is in the index: + * the current hostname + * the current mutt-ng version number - as /usr/local/etc/mailcap, which contains some baseline entries. + The setting for the status bar of the index is controlled via the $status_format variable. For the hostname and version string, there's an expando for $status_format: %h expands to the hostname and %v to the version string. When just configuring: +set status_format = "%v on %h: ..." - _5_._3_._1 _T_h_e _B_a_s_i_c_s _o_f _t_h_e _m_a_i_l_c_a_p _f_i_l_e + mutt-ng will replace the sequence %v with the version string and %h with the host's name. When you are, for example, running mutt-ng version 1.5.9i on host mailhost, you'll see the following when you're in the index: +Mutt-ng 1.5.9i on mailhost: ... - A mailcap file consists of a series of lines which are comments, blank, or def- - initions. + In the index, there're more useful information one could want to see: + * which mailbox is open + * how man new, flagged or postponed messages + * ... - A comment line consists of a # character followed by anything you want. + To include the mailbox' name is as easy as: +set status_format = "%v on %h: %B: ... - A blank line is blank. + When the currently opened mailbox is Inbox, this will be expanded to: +Mutt-ng 1.5.9i on mailhost: Inbox: ... - A definition line consists of a content type, a view command, and any number of - optional fields. Each field of a definition line is divided by a semicolon ';' - character. + For the number of certain types of messages, one more feature of the format strings is extremely useful. If there aren't messages of a certain type, it may not be desired to print just that there aren't any but instead only print something if there are any. - The content type is specified in the MIME standard type/subtype method. For - example, text/plain, text/html, image/gif, etc. In addition, the mailcap for- - mat includes two formats for wildcards, one using the special '*' subtype, the - other is the implicit wild, where you only include the major type. For exam- - ple, image/*, or video, will match all image types and video types, respec- - tively. +3.2. Conditional Expansion - 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. + To only print the number of messages if there are new messages in the current mailbox, further extend $status_format to: +set status_format = "%v on %h: %B %?n?%n new? ... - So, in the simplest form, you can send a text/plain message to the external - pager more on stdin: + This feature is called nonzero-printing and works as this: some expandos may be optionally printed nonzero, i.e. a portion of the format string is only evaluated if the value of the expando is different from zero. The basic syntax is: +%??? - text/plain; more + which tells mutt-ng to only look at if the value of the %?&? - text/plain; more %s + Using this we can make mutt-ng to do the following: + * make it print ``n new messages'' whereby n is the count but only if there new ones + * and make it print ``no new messages'' if there aren't any - Perhaps you would like to use lynx to interactively view a text/html message: + The corresponding configuration is: +set status_format = "%v on %h: %B: %?n?%n new messages&no new messages? ... - text/html; lynx %s + This doubles the use of the ``new messages'' string because it'll get always printed. Thus, it can be shortened to: +set status_format = "%v on %h: %B: %?n?%n&no? new messages ... - In this case, lynx does not support viewing a file from stdin, so you must use - the %s syntax.

Modifications and Padding - The Mutt-ng E-Mail Client 57 + Besides the information given so far, there're even more features of format strings: + * 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 (_). - want to have it convert the text/html to text/plain, then you can use: + Also, there's a feature called Padding supplied by the following two expandos: %|X and %>X . - text/html; lynx -dump %s | more + %|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: - 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: +set status_format = "%v on %h: %B: %?n?%n&no? new messages %|-" - text/html; lynx %s - text/*; more + %>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 %>): - This is the simplest form of a mailcap file. +set status_format = "%B: %?n?%n&no? new messages %> (%v on %h)" - _5_._3_._2 _S_e_c_u_r_e _u_s_e _o_f _m_a_i_l_c_a_p +4. Using Tags - 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 _m_a_i_l_c_a_p___s_a_n_i_t_i_z_e (section 6.3.117 , page 94) variable. + Sometimes it is desirable to perform an operation on a group of messages all at once rather than one at a time. An example might be to save messages to a mailing list to a separate folder, or to delete all messages with a given subject. To tag all messages matching a pattern, use the tag-pattern function, which is bound to ``shift-T'' by default. Or you can select individual messages by hand using the ``tag-message'' function, which is bound to ``t'' by default. See patterns for Mutt-ng's pattern matching syntax. - 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: + Once you have tagged the desired messages, you can use the ``tag-prefix'' operator, which is the ``;'' (semicolon) key by default. When the ``tag-prefix'' operator is used, the next operation will be applied to all tagged messages if that operation can be used in that manner. If the $auto_tag variable is set, the next operation applies to the tagged messages automatically, without requiring the ``tag-prefix''. - _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 alterna- - tive to correct quoting in the first place. + In macro or push commands, you can use the ``tag-prefix-cond'' operator. If there are no tagged messages, mutt will "eat" the rest of the macro to abort it's execution.Mutt-ng will stop "eating" the macro when it encounters the ``end-cond'' operator; after this operator the rest of the macro will be executed asnormal. - 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): +5. Using Hooks - text/test-mailcap-bug; cat %s; copiousoutput; test=charset=%{charset} \ - && test "`echo $charset | tr '[A-Z]' '[a-z]'`" != iso-8859-1 + A hook is a concept borrowed from the EMACS editor which allows you to execute arbitrary commands before performing some operation. For example, you may wish to tailor your configuration based upon which mailbox you are reading, or to whom you are sending mail. In the Mutt-ng world, a hook consists of a regexp or patterns along with a configuration option/command. See + * folder-hook + * send-hook + * message-hook + * save-hook + * mbox-hook + * fcc-hook + * fcc-save-hook - _5_._3_._3 _A_d_v_a_n_c_e_d _m_a_i_l_c_a_p _U_s_a_g_e + for specific details on each type of hook available. - _5_._3_._3_._1 _O_p_t_i_o_n_a_l _F_i_e_l_d_s + Note: if a hook changes configuration settings, these changes remain effective until the end of the current mutt session. As this is generally not desired, a default hook needs to be added before all other hooks to restore configuration defaults. Here is an example with send-hook and the my_hdr directive: +send-hook . 'unmy_hdr From:' +send-hook ~C/=C'^b@b\.b$' my_hdr from: c@c.c - In addition to the required content-type and view command fields, you can add - semi-colon ';' separated fields to set flags and other options. Mutt-ng recog- - nizes the following optional fields: +5.1. Message Matching in Hooks - 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 + Hooks that act upon messages (send-hook, save-hook, fcc-hook,message-hook )are evaluated in a slightly different manner. For the other types of hooks, a regexp is sufficient. But in dealing with messages a finer grain of control is needed for matching since for different purposes you want to match different criteria. - The Mutt-ng E-Mail Client 58 + Mutt-ng allows the use of the patterns language for matching messages in hook commands. This works in exactly the same way as it would when limiting orsearching 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.). - (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: - - text/html; lynx -dump %s ; copiousoutput + 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/=t ^me@cs\.hmc\.edu$' 'my_hdr From: Mutt-ng User ' - This will cause lynx to format the text/html output as text/plain - and Mutt-ng will use your standard pager to display the results. + which would execute the given command when sending mail to me@cs.hmc.edu. - needsterminal - Mutt-ng uses this flag when viewing attachments with _a_u_t_o_v_i_e_w (sec- - tion 5.4 , page 60), in order to decide whether it should honor - the setting of the _$_w_a_i_t___k_e_y (section 6.3.332 , page 145) 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 _$_w_a_i_t___k_e_y (section 6.3.332 , page 145) and the exit - status of the program to decide if it will ask you to press a key - after the external program has exited. In all other situations it - will not prompt you for a key. + However, it is not required that you write the pattern to match using the full searching language. You can still specify a simple regular expression like the other hooks, in which case Mutt-ng will translate your pattern into the full language, using the translation specified by the default-hook variable. The pattern is translated at the time the hook is declared, so the value of default-hook that is in effect at that time will be used. - compose= - This flag specifies the command to use to create a new attachment - of a specific MIME type.

This command differs from the compose - command in that mutt will expect standard MIME headers on the data. - This can be used to specify parameters, filename, description, etc. - for a new attachment. Mutt-ng supports this from the compose - menu. - - print= - This flag specifies the command to use to print a specific MIME - type.
