There is even more information available in the Mutt FAQ and - various web pages. See the Mutt Page for more details. - - The keybindings described in this section are the defaults as - distributed. Your local system administrator may have altered the - defaults for your site. You can always type ``?'' in any menu to - display the current bindings. - - The first thing you need to do is invoke mutt, simply by typing mutt - at the command line. There are various command-line options, see - either the mutt man page or the ``reference''. - - 2.1. Moving Around in Menus - - Information is presented in menus, very similar to ELM. Here is a - table showing the common keys used to navigate menus in Mutt. - - j or Down next-entry move to the next entry - k or Up previous-entry move to the previous entry - z or PageDn page-down go to the next page - Z or PageUp page-up go to the previous page - = or Home first-entry jump to the first entry - * or End last-entry jump to the last entry - q quit exit the current menu - ? help list all keybindings for the current menu - 22..22..

RReeaaddiinngg MMaaiill -- TThhee IInnddeexx aanndd PPaaggeerr + _1_. _I_n_t_r_o_d_u_c_t_i_o_n - Similar to many other mail clients, there are two modes in which mail - is read in Mutt. The first is the index of messages in the mailbox, - which is called the ``index'' in Mutt. The second mode is the display - of the message contents. This is called the ``pager.'' + _1_._1 _O_v_e_r_v_i_e_w - The next few sections describe the functions provided in each of these - modes. + MMuutttt--nngg is a small but very powerful text-based MIME mail client.

SSttaattuuss FFllaaggss - - In addition to who sent the message and the subject, a short summary - of the disposition of each message is printed beside the message - number. Zero or more of the following ``flags'' may appear, which - mean: - - DD message is deleted (is marked for deletion) - - dd message have attachments marked for deletion - - KK contains a PGP public key - - NN message is new - - OO message is old - - PP message is PGP encrypted - - rr message has been replied to - - SS message is signed, and the signature is succesfully verified - - ss message is signed - - !! message is flagged - - ** message is tagged - - Some of the status flags can be turned on or off using - - · sseett--ffllaagg (default: w) - - · cclleeaarr--ffllaagg (default: W) - - Furthermore, the following flags reflect who the message is addressed - to. They can be customized with the ``$to_chars'' variable. - - ++ message is to you and you only - - TT message is to you, but also to or cc'ed to others - - CC message is cc'ed to you - - FF message is from you - - LL message is sent to a subscribed mailing list - - 22..33..22.. TThhee PPaaggeerr - - By default, Mutt uses its builtin pager to display the body of - messages. The pager is very similar to the Unix program _l_e_s_s though - not nearly as featureful. - - go down one line - display the next page (or next message if at the end of a message) - - go back to the previous page - n search for next match - S skip beyond quoted text - T toggle display of quoted text - ? show keybindings - / search for a regular expression (pattern) - ESC / search backwards for a regular expression - \ toggle search pattern coloring - ^ jump to the top of the message - - In addition, many of the functions from the index are available in the - pager, such as delete-message or copy-message (this is one advantage - over using an external pager to view messages). - - Also, the internal pager supports a couple other advanced features. - For one, it will accept and translate the ``standard'' nroff sequences - for bold and underline. These sequences are a series of either the - letter, backspace (^H), the letter again for bold or the letter, - backspace, ``_'' for denoting underline. Mutt will attempt to display - these in bold and underline respectively if your terminal supports - them. If not, you can use the bold and underline ``color'' objects to - specify a color or mono attribute for them. - - Additionally, the internal pager supports the ANSI escape sequences - for character attributes. Mutt translates them into the correct color - and character settings.

TThhrreeaaddeedd MMooddee + +o mutt-ng-users@lists.berlios.de -- This is where the mutt-ng user support + happens. - When the mailbox is ``sorted'' by _t_h_r_e_a_d_s, there are a few additional - functions available in the _i_n_d_e_x and _p_a_g_e_r modes. + The Mutt Next Generation E-Mail Client 1 - ^D delete-thread delete all messages in the current thread - ^U undelete-thread undelete all messages in the current thread - ^N next-thread jump to the start of the next thread - ^P previous-thread jump to the start of the previous thread - ^R read-thread mark the current thread as read - ESC d delete-subthread delete all messages in the current subthread - ESC u undelete-subthread undelete all messages in the current subthread - ESC n next-subthread jump to the start of the next subthread - ESC p previous-subthread jump to the start of the previous subthread - ESC r read-subthread mark the current subthread as read - ESC t tag-thread toggle the tag on the current thread - ESC v collapse-thread toggle collapse for the current thread - ESC V collapse-all toggle collapse for all threads - P parent-message jump to parent message in thread - - NNoottee:: Collapsing a thread displays only the first message in the - thread and hides the others. This is useful when threads contain so - many messages that you can only see a handful of threads on the - screen. See %M in ``$index_format''. For example, you could use - "%?M?(#%03M)&(%4l)?" in ``$index_format'' to optionally display the - number of hidden messages if the thread is collapsed. - - See also: ``$strict_threads''. - - 2.3.4. Miscellaneous Functions - - create-alias (default: a) - - Creates a new alias based upon the current message (or prompts for a - new one). Once editing is complete, an ``alias'' command is added to - the file specified by the ``$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. - - check-traditional-pgp (default: ESC P) - - This function will search the current message for content signed or - encrypted with PGP the "traditional" way, that is, without proper MIME - tagging. Technically, this function will temporarily change the MIME - content types of the body parts containing PGP data; this is similar - to the ``edit-type'' function's effect. - - display-toggle-weed (default: h) - - Toggles the weeding of message header fields specified by ``ignore'' - commands. - - edit (default: e) - - This command (available in the ``index'' and ``pager'') allows you to - edit the raw current message as it's present in the mail folder. - After you have finished editing, the changed message will be appended - to the current folder, and the original message will be marked for - deletion. - - edit-type - (default: ^E on the attachment menu, and in the pager and index menus; - ^T on the compose menu) - - This command is used to temporarily edit an attachment's content type - to fix, for instance, bogus character set parameters. When invoked - from the index or from the pager, you'll have the opportunity to edit - the top-level attachment's content type. On the ``attachment menu'', - you can change any attachment's content type. These changes are not - persistent, and get lost upon changing folders. - - Note that this command is also available on the ``compose menu''. - There, it's used to fine-tune the properties of attachments you are - going to send. - - enter-command (default: ``:'') - - This command is used to execute any command you would normally put in - a configuration file. A common use is to check the settings of - variables, or in conjunction with ``macros'' to change settings on the - fly. - - extract-keys (default: ^K) - - This command extracts PGP public keys from the current or tagged - message(s) and adds them to your PGP public key ring. - - forget-passphrase (default: ^F) - - This command wipes the passphrase(s) from memory. It is useful, if you - misspelled the passphrase. - - list-reply (default: L) - - Reply to the current or tagged message(s) by extracting any addresses - which match the addresses given by the ``lists or subscribe'' - commands, but also honor any Mail-Followup-To header(s) if the - ``$honor_followup_to'' configuration variable is set. Using this when - replying to messages posted to mailing lists helps avoid duplicate - copies being sent to the author of the message you are replying to. - - pipe-message (default: |) - - Asks for an external Unix command and pipes the current or tagged - message(s) to it. The variables ``$pipe_decode'', ``$pipe_split'', - ``$pipe_sep'' and ``$wait_key'' control the exact behaviour of this - function. - - resend-message (default: ESC e) - - With resend-message, mutt takes the current message as a template for - a new message. This function is best described as "recall from - arbitrary folders". It can conveniently be used to forward MIME - messages while preserving the original mail structure. Note that the - amount of headers included here depends on the value of the ``$weed'' - variable. - - This function is also available from the attachment menu. You can use - this to easily resend a message which was included with a bounce - message as a message/rfc822 body part. - - sshheellll--eessccaappee (default: !) - - Asks for an external Unix command and executes it. The ``$wait_key'' - can be used to control whether Mutt will wait for a key to be pressed - when the command returns (presumably to let the user read the output - of the command), based on the return status of the named command. - - ttooggggllee--qquuootteedd (default: T) - - The _p_a_g_e_r uses the ``$quote_regexp'' variable to detect quoted text - when displaying the body of the message. This function toggles the - display of the quoted material in the message. It is particularly - useful when are interested in just the response and there is a large - amount of quoted text in the way. - - sskkiipp--qquuootteedd (default: S) - - This function will go to the next line of non-quoted text which come - after a line of quoted text in the internal pager. - - 22..44.. SSeennddiinngg MMaaiill - - The following bindings are available in the _i_n_d_e_x for sending - messages. - - m compose compose a new message - r reply reply to sender - g group-reply reply to all recipients - L list-reply reply to mailing list address - f forward forward message - b bounce bounce (remail) message - ESC k mail-key mail a PGP public key to someone - - Bouncing a message sends the message as is to the recipient you - specify. Forwarding a message allows you to add comments or modify - the message you are forwarding. These items are discussed in greater - detail in the next chapter ````Forwarding and Bouncing Mail''''. - - Mutt will then enter the _c_o_m_p_o_s_e menu and prompt you for the - recipients to place on the ``To:'' header field. Next, it will ask - you for the ``Subject:'' field for the message, providing a default if - you are replying to or forwarding a message. See also ``$askcc'', - ``$askbcc'', ``$autoedit'', ``$bounce'', and ``$fast_reply'' for - changing how Mutt asks these questions. - - Mutt will then automatically start your ``$editor'' on the message - body. If the ``$edit_headers'' variable is set, the headers will be - at the top of the message in your editor. Any messages you are - replying to will be added in sort order to the message, with - appropriate ``$attribution'', ``$indent_string'' and - ``$post_indent_string''. When forwarding a message, if the - ``$mime_forward'' variable is unset, a copy of the forwarded message - will be included. If you have specified a ``$signature'', it will be - appended to the message. - - Once you have finished editing the body of your mail message, you are - returned to the _c_o_m_p_o_s_e menu. The following options are available: - - a attach-file attach a file - A attach-message attach message(s) to the message - ESC k attach-key attach a PGP public key - d edit-description edit description on attachment - D detach-file detach a file - t edit-to edit the To field - ESC f edit-from edit the From field - r edit-reply-to edit the Reply-To field - c edit-cc edit the Cc field - b edit-bcc edit the Bcc field - y send-message send the message - s edit-subject edit the Subject - S smime-menu select S/MIME options - f edit-fcc specify an ``Fcc'' mailbox - p pgp-menu select PGP options - P postpone-message postpone this message until later - q quit quit (abort) sending the message - w write-fcc write the message to a folder - i ispell check spelling (if available on your system) - ^F forget-passphrase wipe passphrase(s) from memory - - NNoottee:: The attach-message function will prompt you for a folder to - attach messages from. You can now tag messages in that folder and they - will be attached to the message you are sending. Note that certain - operations like composing a new mail, replying, forwarding, etc. are - not permitted when you are in that folder. The %r in - ``$status_format'' will change to a 'A' to indicate that you are in - attach-message mode. - - 2.4.1. Editing the message header - - When editing the header of your outgoing message, there are a couple - of special features available. - - If you specify - Fcc: filename - Mutt will pick up filename just as if you had used the edit-fcc - function in the compose menu. - - You can also attach files to your message by specifying - Attach: filename [ description ] - where filename is the file to attach and description is an optional - string to use as the description of the attached file. - - When replying to messages, if you remove the In-Reply-To: field from - the header field, Mutt will not generate a References: field, which - allows you to create a new message thread. - - Also see ``edit_headers''. - - 2.4.2. Using Mutt with PGP - - If you want to use PGP, you can specify - - Pgp: [ E | S | S ] - - ``E'' encrypts, ``S'' signs and ``S'' signs with the given key, - setting ``$pgp_sign_as'' permanently. - - If you have told mutt to PGP encrypt a message, it will guide you - through a key selection process when you try to send the message. - Mutt will not ask you any questions about keys which have a certified - user ID matching one of the message recipients' mail addresses. - However, there may be situations in which there are several keys, - weakly certified user ID fields, or where no matching keys can be - found. - - In these cases, you are dropped into a menu with a list of keys from - which you can select one. When you quit this menu, or mutt can't find - any matching keys, you are prompted for a user ID. You can, as - usually, abort this prompt using ^G. When you do so, mutt will return - to the compose screen. - - Once you have successfully finished the key selection, the message - will be encrypted using the selected public keys, and sent out. - - Most fields of the entries in the key selection menu (see also - ``$pgp_entry_format'') have obvious meanings. But some explanations - 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 capabilities: A minus sign (-) means that the key - cannot be used for encryption. A dot (.) means that it's marked as a - signature key in one of the user IDs, but may also be used for - encryption. The letter e indicates that this key can be used for - encryption. - - The second character indicates the key's signing capabilities. Once - again, a ``-'' implies ``not for signing'', ``.'' implies that the key - is marked as an encryption key in one of the user-ids, and ``s'' - denotes a key which can be used for signing. - - Finally, the validity field (%t) indicates how well-certified a user- - id is. A question mark (?) indicates undefined validity, a minus - character (-) marks an untrusted association, a space character means - a partially trusted association, and a plus character (+) indicates - complete validity. - - 2.4.3. Sending anonymous messages via mixmaster. - - 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. - - To use it, you'll have to obey certain restrictions. Most important, - you cannot use the Cc and Bcc headers. To tell Mutt to use mixmaster, - you have to select a remailer chain, using the mix function on the - compose menu. - - 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. - - You can navigate in the chain using the chain-prev and chain-next - functions, which are by default bound to the left and right arrows and - to the h and l keys (think vi keyboard bindings). To insert a - remailer at the current chain position, use the insert function. To - append a remailer behind the current chain position, use select-entry - or append. You can also delete entries from the chain, using the - corresponding function. Finally, to abandon your changes, leave the - menu, or accept them pressing (by default) the Return key. - - Note that different remailers do have different capabilities, - indicated in the %c entry of the remailer menu lines (see - ``$mix_entry_format''). Most important is the ``middleman'' - capability, indicated by a capital ``M'': This means that the remailer - in question cannot be used as the final element of a chain, but will - only forward messages to other mixmaster remailers. For details on - the other capabilities, please have a look at the mixmaster - documentation. - - 2.5. Forwarding and Bouncing Mail - - Bouncing and forwarding let you send an existing message to recipients - that you specify. Bouncing a message uses the ``sendmail'' command to - send a copy to alternative addresses as if they were the message's - original recipients. Forwarding a message, on the other hand, allows - you to modify the message before it is resent (for example, by adding - your own comments). - The following keys are bound by default: - - f forward forward message - b bounce bounce (remail) message - - Forwarding can be done by including the original message in the new - message's body (surrounded by indicating lines) or including it as a - MIME attachment, depending on the value of the ``$mime_forward'' - variable. Decoding of attachments, like in the pager, can be - controlled by the ``$forward_decode'' and ``$mime_forward_decode'' - variables, respectively. The desired forwarding format may depend on - the content, therefore $mime_forward is a quadoption which, for - example, can be set to ``ask-no''. - - The inclusion of headers is controlled by the current setting of the - ``$weed'' variable, unless ``mime_forward'' is set. - - Editing the message to forward follows the same procedure as sending - or replying to a message does. - - 22..66.. PPoossttppoonniinngg MMaaiill - - 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 ``$postponed'' variable. This - means that you can recall the message even if you exit Mutt and then - restart it at a later time. - - Once a message is postponed, there are several ways to resume it. - From the command line you can use the ``-p'' option, or if you _c_o_m_p_o_s_e - a new message from the _i_n_d_e_x or _p_a_g_e_r you will be prompted if - postponed messages exist. If multiple messages are currently - postponed, the _p_o_s_t_p_o_n_e_d menu will pop up and you can select which - message you would like to resume. - - NNoottee:: If you postpone a reply to a message, the reply setting of the - message is only updated when you actually finish the message and send - it. Also, you must be in the same folder with the message you replied - to for the status of the message to be updated. - - See also the ``$postpone'' quad-option. - - 22..77.. RReeaaddiinngg nneewwss vviiaa NNNNTTPP - - If compiled with ``--enable-nntp'' option, Mutt can read news from - newsserver via NNTP. You can open a newsgroup with function ``change- - newsgroup'' (default: i). Default newsserver can be obtained from - _N_N_T_P_S_E_R_V_E_R environment variable. Like other news readers, info about - subscribed newsgroups is saved in file by ``$newsrc'' variable. - Article headers are cached and can be loaded from file when newsgroup - entered instead loading from newsserver. - - 33.. CCoonnffiigguurraattiioonn - - While the default configuration (or ``preferences'') make Mutt usable - right out of the box, it is often desirable to tailor Mutt to suit - your own tastes. When Mutt is first invoked, it will attempt to read - the ``system'' configuration file (defaults set by your local system - administrator), unless the ``-n'' ``command line'' option is - specified. This file is typically /usr/local/share/mutt/Muttrc or - /etc/Muttrc. Mutt will next look for a file named .muttrc in your home - directory. If this file does not exist and your home directory has a - subdirectory named .mutt, mutt try to load a file named .mutt/muttrc. - - .muttrc is the file where you will usually place your ``commands'' to - configure Mutt. - 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 running version 0.88 of mutt, - this file will be sourced instead of the Muttrc 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'' ``command line'' - switch or using the show-version key (default: V) from the index menu. - - 3.1. Syntax of Initialization Files - - An initialization file consists of a series of ``commands''. Each - line of the file may contain one or more commands. When multiple - commands are used, they must be separated by a semicolon (;). - - set realname='Mutt user' ; ignore x- - - The hash mark, or pound sign (``#''), is used as a ``comment'' charac­ - ter. You can use it to annotate your initialization file. All text - after the comment character to the end of the line is ignored. For - example, - - my_hdr X-Disclaimer: Why are you listening to me? # This is a comment - - Single quotes (') and double quotes (") can be used to quote strings - which contain spaces or other special characters. The difference - between the two types of quotes is similar to that of many popular - shell programs, namely that a single quote is used to specify a - literal string (one that is not interpreted for shell variables or - quoting with a backslash [see next paragraph]), while double quotes - indicate a string for which should be evaluated. For example, - backtics are evaluated inside of double quotes, but not for single - quotes. - - \ quotes the next character, just as in shells such as bash and zsh. - For example, if want to put quotes ``"'' inside of a string, you can - use ``\'' to force the next character to be a literal instead of - interpreted character. - - set realname="Michael \"MuttDude\" Elkins" - - ``\\'' means to insert a literal ``\'' into the line. ``\n'' and - ``\r'' have their usual C meanings of linefeed and carriage-return, - respectively. - - 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. - - It is also possible to substitute the output of a Unix command in an - initialization file. This is accomplished by enclosing the command in - backquotes (``). For example, - - my_hdr X-Operating-System: `uname -a` - - 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. - - 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, - - set record=+sent_on_$HOSTNAME - - The commands understood by mutt are explained in the next paragraphs. - For a complete list, see the ``command reference''. - - 3.2. Defining/Using aliases - - Usage: alias key address [ , address, ... ] - - It's usually very cumbersome to remember or type out the address of - someone you are communicating with. Mutt allows you to create - ``aliases'' which map a short string to a full address. - - Note: if you want to create an alias for a group (by specifying more - than one address), you must separate the addresses with a comma - (``,''). - - To remove an alias or aliases (``*'' means all aliases): - - unalias [ * | key ... ] - - alias muttdude me@cs.hmc.edu (Michael Elkins) - alias theguys manny, moe, jack - - Unlike other mailers, Mutt doesn't require aliases to be defined in a - special file. The alias command can appear anywhere in a - configuration file, as long as this file is ``sourced''. - Consequently, you can have multiple alias files, or you can have all - aliases defined in your muttrc. - - On the other hand, the ``create-alias'' function can use only one - file, the one pointed to by the ``$alias_file'' variable (which is - ~/.muttrc by default). This file is not special either, in the sense - that Mutt will happily append aliases to any file, but in order for - the new aliases to take effect you need to explicitly ``source'' this - file too. - For example: - - source /usr/local/share/Mutt.aliases - source ~/.mail_aliases - set alias_file=~/.mail_aliases - - To use aliases, you merely use the alias at any place in mutt where - mutt prompts for addresses, such as the To: or Cc: prompt. You can - also enter aliases in your editor at the appropriate headers if you - have the ``$edit_headers'' variable set. - - 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. - - 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. - - 3.3. Changing the default key bindings - - Usage: bind map key function - - This command allows you to change the default key bindings (operation - invoked when pressing a key). - - map specifies in which menu the binding belongs. Multiple maps may be - specified by separating them with commas (no additional whitespace is - allowed). The currently defined maps are: - - 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 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. - - 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). - - attach - The attachment menu is used to access the attachments on - received messages. - - browser - The browser is used for both browsing the local directory - structure, and for listing all of your incoming mailboxes. - - editor - The editor is the line-based editor the user enters text data. - - index - The index is the list of messages contained in a mailbox. - - compose - The compose menu is the screen used when sending a new message. - - pager - The pager is the mode used to display message/attachment data, - and help listings. - - pgp - The pgp menu is used to select the OpenPGP keys used for - encrypting outgoing messages. - - 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. - - 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?). - - In addition, key may consist of: - - \t tab - 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 - - key does not need to be enclosed in quotes unless it contains a space - (`` ''). - - function specifies which action to take when key is pressed. For a - complete list of functions, see the ``reference''. The special - function noop unbinds the specified key sequence. - - 3.4. Defining aliases for character sets + The Mutt Next Generation E-Mail Client 2 - Usage: charset-hook alias charset - Usage: iconv-hook charset local-charset + +o mutt-ng-devel@lists.berlios.de -- The development mailing list for mutt-ng - The charset-hook command defines an alias for a character set. This - is useful to properly display messages which are tagged with a - character set name not known to mutt. + _1_._4 _S_o_f_t_w_a_r_e _D_i_s_t_r_i_b_u_t_i_o_n _S_i_t_e_s - The iconv-hook command defines a system-specific name for a character - set.

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. + _1_._6 _W_e_b_l_o_g - 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. + If you want to read fresh news about the latest development in Mutt-ng, and get + informed about stuff like interesting, Mutt-ng-related articles and packages + for your favorite distribution, you can read and/or subscribe to our Mutt-ng + development weblog. - Note that the settings are not restored when you leave the mailbox. - For example, a command action to perform is to change the sorting - method based upon the mailbox being read: + _1_._7 _C_o_p_y_r_i_g_h_t - folder-hook mutt set sort=threads + Mutt is Copyright (C) 1996-2000 Michael R.

The crypt-hook command - provides a method by which you can specify the ID of the public key to - be used when encrypting messages to a certain recipient. - - The 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. - - 3.21. Adding key sequences to the keyboard buffer - - Usage: push string - - This command adds the named string to the keyboard buffer. The string - may contain control characters, key names and function names like the - sequence string in the ``macro'' command. You may use it to - automatically run a sequence of commands at startup, or when entering - certain folders. - - 3.22. Executing functions - - Usage: exec function [ function ... ] - - This command can be used to execute any function. Functions are listed - in the ``function reference''. ``exec function'' is equivalent to - ``push ''. - 3.23. Message Scoring - - Usage: score pattern value - Usage: unscore pattern [ pattern ... ] - - The score commands adds value to a message's score if pattern matches - it. pattern is a string in the format described in the ``patterns'' - section (note: For efficiency reasons, patterns which scan information - not available in the index, such as ~b, ~B or ~h, may not be used). - value 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 value 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. - - The unscore command removes score entries from the list. You must - 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. - - 3.24. Spam detection - - Usage: spam pattern format - Usage: nospam pattern - - Mutt has generalized support for external spam-scoring filters. By - defining your spam patterns with the spam and nospam commands, you can - limit, search, and sort your mail based on its spam attributes, as - determined by the external filter. You also can display the spam - attributes in your index display using the %H selector in the - ``$index_format'' variable. (Tip: try %?H?[%H] ? to display spam tags - only when they are defined for a given message.) - - 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. - - 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. - - 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=", " - - 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''.) - - If the $spam_separator variable is unset, then each spam pattern match - supercedes the previous one. Instead of getting joined format strings, - you'll get only the last one to match. - - The spam tag is what will be displayed in the index when you use %H in - the $index_format variable. It's also the string that the ~H pattern- - matching expression matches against for search and limit functions. - And it's what sorting by spam attribute will use as a sort key. - - That's a pretty complicated example, and most people's actual - environments will have only one spam filter. The simpler your - configuration, the more effective mutt can be, especially when it - comes to sorting. - - Generally, when you sort by spam tag, mutt will sort lexically -- that - is, by ordering strings alphnumerically. However, if a spam tag begins - with a number, mutt will sort numerically first, and lexically only - when two numbers are equal in value. (This is like UNIX's sort -n.) A - message with no spam attributes at all -- that is, one that didn't - match any of your spam patterns -- is sorted at lowest priority. - Numbers are sorted next, beginning with 0 and ranging upward. Finally, - non-numeric strings are sorted, with ``a'' taking lower priority than - ``z''. Clearly, in general, sorting by spam tags is most effective - when you can coerce your filter to give you a raw number. But in case - you can't, mutt can still do something useful. - - 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. - - 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. - - 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" - - 3.25. Setting variables - - Usage: set [no|inv]variable[=value] [ variable ... ] - Usage: toggle variable [variable ... ] - Usage: unset variable [variable ... ] - Usage: reset variable [variable ... ] - - This command is used to set (and unset) ``configuration variables''. - There are four basic types of variables: boolean, number, string and - quadoption. boolean variables can be set (true) or unset (false). - number variables can be assigned a positive integer value. - - 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. - - 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.'' - - Prefixing a variable with ``no'' will unset it. Example: set - noaskbcc. - - 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. - - The toggle command automatically prepends the inv prefix to all - specified variables. - - The unset command automatically prepends the no prefix to all - specified variables. - - 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 - - The question mark is actually only required for boolean and quadoption - variables. - - 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. - - With the reset command there exists the special variable ``all'', - which allows you to reset all variables to their system defaults. - - 3.26. Reading initialization commands from another file - - Usage: source filename - - 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. - - If the filename begins with a tilde (``~''), it will be expanded to - the path of your home directory. - - 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|). - - 3.27. Removing hooks - - Usage: unhook [ * | hook-type ] - - 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. + The Mutt Next Generation E-Mail Client 20 - 4. Advanced Usage - - 4.1. Regular Expressions + Often, it is necessary to forward mails to other people. Therefore, mutt-ng + supports forwarding messages in two different ways. - All string patterns in Mutt 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. + 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: - The search is case sensitive if the pattern contains at least one - upper case letter, and case insensitive otherwise. Note that ``\'' - must be quoted if used for a regular expression in an initialization - command: ``\\''. - - A regular expression is a pattern that describes a set of strings. - Regular expressions are constructed analogously to arithmetic - expressions, by using various operators to combine smaller - expressions. - - Note that the regular expression can be enclosed/delimited by either " - or ' which is useful if the regular expression includes a white-space - character. See ``Syntax of Initialization Files'' for more - information on " and ' delimiter processing. To match a literal " or - ' you must preface it with \ (backslash). + ----- Forwarded message from Lucas User ----- - 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. + From: Lucas User + Date: Thu, 02 Dec 2004 03:08:34 +0100 + To: Michael Random + Subject: Re: blackmail - 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. + Pay me EUR 50,000.- cash or your favorite stuffed animal will die + a horrible death. - 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. + ----- End forwarded message ----- - 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: + 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. - [:alnum:] - Alphanumeric characters. + The second mode of forwarding emails with mutt-ng is the so-called _b_o_u_n_c_i_n_g: + when you bounce an email to another address, it will be sent in practically the + same format you send it (except for headers that are created during transport- + ing the message). To bounce a message, press b and enter the recipient email + address. By default, you are then asked whether you really want to bounce the + message to the specified recipient. If you answer with yes, the message will + then be bounced. - [:alpha:] - Alphabetic characters. + 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. - [:blank:] - Space or tab characters. + _2_._8 _P_o_s_t_p_o_n_i_n_g _M_a_i_l - [:cntrl:] - Control characters. + 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 _$_p_o_s_t_p_o_n_e_d (section 7.4.230 , page 145) variable. This means that you can + recall the message even if you exit Mutt-ng and then restart it at a later + time. - [:digit:] - Numeric characters. + Once a message is postponed, there are several ways to resume it. From the + command line you can use the ``-p'' option, or if you _c_o_m_p_o_s_e a new message - [:graph:] - Characters that are both printable and visible. (A space is - printable, but not visible, while an ``a'' is both.) + The Mutt Next Generation E-Mail Client 21 - [:lower:] - Lower-case alphabetic characters. + from the _i_n_d_e_x or _p_a_g_e_r you will be prompted if postponed messages exist. If + multiple messages are currently postponed, the _p_o_s_t_p_o_n_e_d menu will pop up and + you can select which message you would like to resume. - [:print:] - Printable characters (characters that are not control - characters.) + NNoottee:: If you postpone a reply to a message, the reply setting of the message is + only updated when you actually finish the message and send it. Also, you must + be in the same folder with the message you replied to for the status of the + message to be updated. - [:punct:] - Punctuation characters (characters that are not letter, digits, - control characters, or space characters). + See also the _$_p_o_s_t_p_o_n_e (section 7.4.229 , page 145) quad-option. - [:space:] - Space characters (such as space, tab and formfeed, to name a - few). + _3_. _C_o_n_f_i_g_u_r_a_t_i_o_n - [:upper:] - Upper-case alphabetic characters. + _3_._1 _L_o_c_a_t_i_o_n_s _o_f _C_o_n_f_i_g_u_r_a_t_i_o_n _F_i_l_e_s - [:xdigit:] - Characters that are hexadecimal digits. + 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 7.1 , page 83) 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. - 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]. - - Two additional special sequences can appear in character lists. These - apply to non-ASCII character sets, which can have single symbols - (called collating elements) that are represented with more than one - character, as well as several characters that are equivalent for - collating or sorting purposes: - - 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''. - - 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''. - A regular expression matching a single character may be followed by - one of several repetition operators: - - ? 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 - resulting 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. - - Note: If you compile Mutt with the GNU rx 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 - underscore). - - \\W - Matches any character that is not word-constituent. - - \\` - Matches the empty string at the beginning of a buffer (string). - - \\' - Matches the empty string at the end of a buffer. - - 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. Patterns - - Many of Mutt's commands allow you to specify a pattern to match - (limit, tag-pattern, delete-pattern, etc.). There are several ways to - select messages: - - ~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 - ~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) + .muttrc (or .muttngrc for Mutt-ng) is the file where you will usually place + your _c_o_m_m_a_n_d_s (section 7.3 , page 86) to configure Mutt-ng. - Where EXPR, USER, ID, and SUBJECT are ``regular expressions''. - Special attention has to be made when using regular expressions inside - of patterns. Specifically, Mutt'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 (\\). + _3_._2 _B_a_s_i_c _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 - *) The forms <[MAX], >[MIN], [MIN]- and -[MAX] are allowed, too. + An initialization file consists of a series of _c_o_m_m_a_n_d_s (section 7.3 , page + 86). Each line of the file may contain one or more commands. When multiple + commands are used, they must be separated by a semicolon (;). - 4.2.1. Pattern Modifier + set realname='Mutt-ng user' ; ignore x- - 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. + 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, - ^~C \.de$ + my_hdr X-Disclaimer: Why are you listening to me? # This is a comment - 4.2.2. Complex Patterns + Single quotes (') and double quotes (') can be used to quote strings which - Logical AND is performed by specifying more than one criterion. For - example: + The Mutt Next Generation E-Mail Client 22 - ~t mutt ~f elkins + contain spaces or other special characters. The difference between the two + types of quotes is similar to that of many popular shell programs, namely that + a single quote is used to specify a literal string (one that is not interpreted + for shell variables or quoting with a backslash [see next paragraph]), while + double quotes indicate a string for which should be evaluated. For example, + backtics are evaluated inside of double quotes, but nnoott for single quotes. - would select messages which contain the word ``mutt'' in the list of - recipients and that have the word ``elkins'' in the ``From'' header - field. + \ 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 also recognizes the following operators to create more complex - search patterns: + set realname="Michael \"MuttDude\" Elkins" - · ! -- logical NOT operator + ``\\'' means to insert a literal ``\'' into the line. ``\n'' and ``\r'' have + their usual C meanings of linefeed and carriage-return, respectively. - · | -- logical OR operator - - · () -- logical grouping operator - - 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''. - - !(~t mutt|~c mutt) ~f elkins - - Here is an example using white space in the regular expression (note - the ' and " delimiters). For this to match, the mail's subject must - match the ``^Junk +From +Me$'' and it must be from either ``Jim - +Somebody'' or ``Ed +SomeoneElse'': - - '~s "^Junk +From +Me$" ~f ("Jim +Somebody"|"Ed +SomeoneElse")' - - Note that if a regular expression contains parenthesis, or a veritical - bar ("|"), you must enclose the expression in double or single quotes - since those characters are also used to separate different parts of - Mutt's pattern language. For example, - - ~f "me@(mutt\.org|cs\.hmc\.edu)" - - Without the quotes, the parenthesis wouldn't end. This would be - seperated to two OR'd patterns: ~f me@(mutt\.org and cs\.hmc\.edu). - They are never what you want. - - 4.2.3. Searching by Date + 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. - Mutt supports two types of dates, absolute and relative. + 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 ``#''. - Absolute. Dates must be in DD/MM/YY format (month and year are - optional, defaulting to the current month and year). An example of a - valid range of dates is: + # folder-hook . \ + set realname="Michael \"MuttDude\" Elkins" - Limit to messages matching: ~d 20/1/95-31/10 + 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! - If you omit the minimum (first) date, and just specify ``-DD/MM/YY'', - all messages before the given date will be selected. If you omit the - maximum (second) date, and specify ``DD/MM/YY-'', all messages after - the given date will be selected. If you specify a single date with no - dash (``-''), only messages sent on the given date will be selected. + Abstract example: - Error Margins. You can add error margins to absolute dates. An error - margin is a sign (+ or -), followed by a digit, followed by one of the - following units: + line1\ + line2a # line2b\ + line3\ + line4 + line5 - y years - m months - w weeks - d days + 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. - As a special case, you can replace the sign by a ``*'' character, - which is equivalent to giving identical plus and minus error margins. + 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 7.3 , page 86). - Example: To select any messages two weeks around January 15, 2001, - you'd use the following pattern: + The Mutt Next Generation E-Mail Client 23 - Limit to messages matching: ~d 15/1/2001*2w + _3_._3 _E_x_p_a_n_s_i_o_n _w_i_t_h_i_n _v_a_r_i_a_b_l_e_s - Relative. This type of date is relative to the current date, and may - be specified as: + Besides just assign static content to variables, there's plenty of ways of + adding external and more or less dynamic content. - · >offset (messages older than offset units) + _3_._3_._1 _C_o_m_m_a_n_d_s_' _O_u_t_p_u_t - · <offset (messages newer than offset units) + It is possible to substitute the output of a Unix command in an initialization + file. This is accomplished by enclosing the command in backquotes (``) as in, + for example: - · =offset (messages exactly offset units old) + my_hdr X-Operating-System: `uname -a` - offset is specified as a positive number with one of the following - units: + 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. - y years - m months - w weeks - d days + _3_._3_._2 _E_n_v_i_r_o_n_m_e_n_t _V_a_r_i_a_b_l_e_s - Example: to select messages less than 1 month old, you would use + 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 ``$'' sign. For example, - Limit to messages matching: ~d <1m + set record=+sent_on_$HOSTNAME - Note: all dates used when searching are relative to the local time - zone, so unless you change the setting of your ``$index_format'' to - include a %[...] format, these are not the dates shown in the main - index. + sets the _$_r_e_c_o_r_d (section 7.4.246 , page 148) variable to the string _+_s_e_n_t___o_n__ + and appends the value of the evironment variable $HOSTNAME. - 4.3. Using Tags + NNoottee:: There will be no warning if an environment variable is not defined. The + result will of the expansion will then be empty. - Sometimes it is desirable to perform an operation on a group of - messages all at once rather than one at a time. An example might be - to save messages to a mailing list to a separate folder, or to delete - all messages with a given subject. To tag all messages matching a - pattern, use the tag-pattern function, which is bound to ``shift-T'' - by default. Or you can select individual messages by hand using the - ``tag-message'' function, which is bound to ``t'' by default. See - ``patterns'' for Mutt's pattern matching syntax. + _3_._3_._3 _C_o_n_f_i_g_u_r_a_t_i_o_n _V_a_r_i_a_b_l_e_s - Once you have tagged the desired messages, you can use the ``tag- - prefix'' operator, which is the ``;'' (semicolon) key by default. - When the ``tag-prefix'' operator is used, the next operation will be - applied to all tagged messages if that operation can be used in that - manner. If the ``$auto_tag'' variable is set, the next operation - applies to the tagged messages automatically, without requiring the - ``tag-prefix''. + As for environment variables, the values of all configuration variables as + string can be used in the same way, too. For example, - In ``macros'' 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 will stop "eating" - the macro when it encounters the ``end-cond'' operator; after this - operator the rest of the macro will be executed as normal. + set imap_home_namespace = $folder - 4.4.

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 - world, a hook consists of a ``regular expression'' or ``pattern'' - along with a configuration option/command. See + NNoottee:: There're no logical links established in such cases so that the the value + for _$_i_m_a_p___h_o_m_e___n_a_m_e_s_p_a_c_e (section 7.4.101 , page 113) won't change even if + _$_f_o_l_d_e_r (section 7.4.70 , page 105) gets changed. - · ``folder-hook'' + NNoottee:: There will be no warning if a configuration variable is not defined or is + empty.

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 vari- + able. - · ``mbox-hook'' + For example, to view the manual, users can either define two macros like the + following - · ``fcc-hook'' + macro generic "!less -r /path/to/manual" "Show manual" + macro pager "!less -r /path/to/manual" "Show manual" - · ``fcc-save-hook'' + for generic, pager and index. The alternative is to define a custom variable + like so: - for specific details on each type of hook available. + 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" - 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: + to re-use the command sequence as in: - send-hook .

Message Matching in Hooks + Using this feature, arbitrary sequences can be defined once and recalled and + reused where necessary. More advanced scenarios could include to save a vari- + able's value at the beginning of macro sequence and restore it at end. - 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 ``regular expression'' 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. + 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. - Mutt allows the use of the ``search pattern'' language for matching - messages in hook commands. This works in exactly the same way as it - would when limiting or searching the mailbox, except that you are - restricted to those operators which match information mutt extracts - from the header of the message (i.e. from, to, cc, date, subject, - etc.). + The complete removal is done via the unset keyword. - For example, if you wanted to set your return address based upon - sending mail to a specific address, you could do something like: + After the following sequence: - send-hook '~t ^me@cs\.hmc\.edu$' 'my_hdr From: Mutt User ' + set user_foo = 42 + set user_foo = 666 - which would execute the given command when sending mail to - me@cs.hmc.edu. + the variable $user_foo has a current value of 666 and an initial of 42. The + query - However, it is not required that you write the pattern to match using - the full searching language. You can still specify a simple regular - expression like the other hooks, in which case Mutt will translate - your pattern into the full language, using the translation specified - by the ``$default_hook'' variable. The pattern is translated at the - time the hook is declared, so the value of ``$default_hook'' that is - in effect at that time will be used. + set ?user_foo - 4.5. External Address Queries + The Mutt Next Generation E-Mail Client 25 - Mutt supports connecting to external directory databases such as LDAP, - ph/qi, bbdb, or NIS through a wrapper script which connects to mutt - using a simple interface. Using the ``$query_command'' variable, you - specify the wrapper command to use. For example: + will show 666. After doing the reset via - set query_command = "mutt_ldap_query.pl '%s'" + reset user_foo - 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. - - An example multiple response output: + a following query will give 42 as the result. After unsetting it via - Searching database ... 20 entries ... 3 matching: - me@cs.hmc.edu Michael Elkins mutt dude - blong@fiction.net Brandon Long mutt and more - roessler@guug.de Thomas Roessler mutt pgp - - There are two mechanisms for accessing the query function of mutt. - One is to do a query from the index menu using the query function - (default: Q). This will prompt for a query, then bring up the query - menu which will list the matching responses. From the query menu, you - can select addresses to create aliases, or to mail. You can tag - multiple addresses to mail, start a new query, or have a new query - appended to the current responses. - - 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. - - 4.6. Mailbox Formats - - Mutt supports reading and writing of four different mailbox formats: - mbox, MMDF, MH and Maildir. The mailbox type is autodetected, so - there is no need to use a flag for different mailbox types. When - creating new mailboxes, Mutt uses the default specified with the - ``$mbox_type'' variable. - - mbox. This is the most widely used mailbox format for UNIX. All - messages are stored in a single file. Each message has a line of the - form: - - From me@cs.hmc.edu Fri, 11 Apr 1997 11:44:56 PST - - to denote the start of a new message (this is often referred to as the - ``From_'' line). - - MMDF. This is a variant of the mbox format. Each message is - surrounded by lines containing ``^A^A^A^A'' (four control-A's). - - MH. A radical departure from mbox and MMDF, a mailbox consists of a - directory and each message is stored in a separate file. The filename - indicates the message number (however, this is may not correspond to - the message number Mutt displays). Deleted messages are renamed with a - comma (,) prepended to the filename. Note: Mutt detects this type of - mailbox by looking for either .mh_sequences or .xmhcache (needed to - distinguish normal directories from MH mailboxes). - - Maildir. The newest of the mailbox formats, used by the Qmail MTA (a - replacement for sendmail). Similar to MH, except that it adds three - subdirectories of the mailbox: tmp, new and cur. Filenames for the - messages are chosen in such a way they are unique, even when two - programs are writing the mailbox over NFS, which means that no file - locking is needed. - - 4.7. Mailbox Shortcuts - - There are a number of built in shortcuts which refer to specific - mailboxes. These shortcuts can be used anywhere you are prompted for - a file or mailbox path. - - · ! -- refers to your ``$spoolfile'' (incoming) mailbox - - · > -- refers to your ``$mbox'' file - - · < -- refers to your ``$record'' file - - · - or !! -- refers to the file you've last visited - - · ~ -- refers to your home directory - - · = or + -- refers to your ``$folder'' directory - - · @alias -- refers to the ``default save folder'' as determined by - the address of the alias - - 4.8. Handling Mailing Lists - - Mutt has a few configuration options that make dealing with large - amounts of mail easier. The first thing you must do is to let Mutt - know what addresses you consider to be mailing lists (technically this - does not have to be a mailing list, but that is what it is most often - used for), and what lists you are subscribed to. This is accomplished - through the use of the ``lists and subscribe'' commands in your - muttrc. - - Now that Mutt knows what your mailing lists are, it can do several - things, the first of which is the ability to show the name of a list - through which you received a message (i.e., of a subscribed list) in - the index menu display. This is useful to distinguish between - personal and list mail in the same mailbox. In the ``$index_format'' - variable, the escape ``%L'' will return the string ``To '' 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 index menu and pager, helps reduce - the clutter by only replying to the known mailing list addresses - instead of all recipients (except as specified by Mail-Followup-To, - see below). - - Mutt also supports the Mail-Followup-To header. When you send a - message to a list of recipients which includes one or several - subscribed mailing lists, and if the ``$followup_to'' option is set, - mutt will generate a Mail-Followup-To header which contains all the - recipients to whom you send this message, but not your address. This - indicates that group-replies or list-replies (also known as - ``followups'') to this message should only be sent to the original - recipients of the message, and not separately to you - you'll receive - your copy through one of the mailing lists you are subscribed to. - - Conversely, when group-replying or list-replying to a message which - has a Mail-Followup-To header, mutt will respect this header if the - ``$honor_followup_to'' configuration variable is set. Using list- - reply will in this case also make sure that the reply goes to the - mailing list, even if it's not specified in the list of recipients in - the Mail-Followup-To. - - Note that, when header editing is enabled, you can create a Mail- - Followup-To header manually. Mutt 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 uses the ``$reply_to'' variable to help decide which - address to use. If set, you will be prompted as to whether or not you - would like to use the address given in the ``Reply-To'' field, or - reply directly to the address given in the ``From'' field. When - unset, the ``Reply-To'' field will be used when present. - - The ``X-Label:'' header field can be used to further identify mailing - lists or list subject matter (or just to annotate messages - individually). The ``$index_format'' variable's ``%y'' and ``%Y'' - escapes can be used to expand ``X-Label:'' fields in the index, and - Mutt's pattern-matcher can match regular expressions to ``X-Label:'' - fields with the ``y'' selector. ``X-Label:'' is not a standard - message header field, but it can easily be inserted by procmail and - other mail filtering agents. - - Lastly, Mutt has the ability to ``sort'' the mailbox into ``threads''. - A thread is a group of messages which all relate to the same subject. - This is usually organized into a tree-like structure where a message - and all of its replies are represented graphically. If you've ever - used a threaded news client, this is the same concept. It makes - dealing with large volume mailing lists easier because you can easily - delete uninteresting threads and quickly find topics of value. - - 4.9. Delivery Status Notification (DSN) Support - - 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. ``$dsn_notify'' is used to - request receipts for different results (such as failed message, - message delivered, etc.). ``$dsn_return'' requests how much of your - message should be returned with the receipt (headers or full message). - Refer to the man page on sendmail for more details on DSN. - - 4.10. POP3 Support (OPTIONAL) - - If Mutt was compiled with POP3 support (by running the configure - script with the --enable-pop flag), it has the ability to work with - mailboxes located on a remote POP3 server and fetch mail for local - browsing. - - 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, - ie: pop://popserver:port/. - - You can also specify different username for each folder, ie: - pop://username@popserver[:port]/. - - Polling for new mail is more expensive over POP3 than locally. For - this reason the frequency at which Mutt will check for mail remotely - can be controlled by the ``$pop_checkinterval'' variable, which - defaults to every 60 seconds. - - If Mutt was compiled with SSL support (by running the configure script - with the --with-ssl flag), connections to POP3 servers can be - encrypted. This naturally requires that the server supports SSL - encrypted connections. To access a folder with POP3/SSL, you should - use pops: prefix, ie: pops://[username@]popserver[:port]/. - - Another way to access your POP3 mail is the fetch-mail function - (default: G). It allows to connect to ``pop_host'', fetch all your - new mail and place it in the local ``spoolfile''. After this point, - Mutt runs exactly as if the mail had always been local. - - Note: If you only need to fetch all messages to local mailbox you - should consider using a specialized program, such as fetchmail - - 4.11. IMAP Support (OPTIONAL) - - If Mutt was compiled with IMAP support (by running the configure - script with the --enable-imap flag), it has the ability to work with - folders located on a remote IMAP server. - - 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. - - You can select an alternative port by specifying it with the server, - ie: imap://imapserver:port/INBOX. - - You can also specify different username for each folder, ie: - imap://username@imapserver[:port]/INBOX. - - If Mutt was compiled with SSL support (by running the configure script - with the --with-ssl flag), connections to IMAP servers can be - encrypted. This naturally requires that the server supports SSL - encrypted connections. To access a folder with IMAP/SSL, you should - use imaps://[username@]imapserver[:port]/path/to/folder as your folder - path. - - Pine-compatible notation is also supported, ie - {[username@]imapserver[:port][/ssl]}path/to/folder - - Note that not all servers use / as the hierarchy separator. Mutt - should correctly notice which separator is being used by the server - and convert paths accordingly. - - When browsing folders on an IMAP server, you can toggle whether to - look at only the folders you are subscribed to, or all folders with - the toggle-subscribed command. See also the ``$imap_list_subscribed'' - variable. - - Polling for new mail on an IMAP server can cause noticeable delays. - So, you'll want to carefully tune the ``$mail_check'' and ``$timeout'' - variables. Personally I use - - set mail_check=90 - set timeout=15 - - with relatively good results over my slow modem line. - - 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. - - 4.11.1. The Folder Browser - - 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: - - · In lieu of file permissions, mutt displays the string "IMAP", - possibly followed by the symbol "+", indicating that the entry - contains both messages and subfolders. On Cyrus-like servers - folders will often contain both messages and subfolders. - - · For the case where an entry can contain both messages and - subfolders, the selection key (bound to enter by default) will - choose to descend into the subfolder view. If you wish to view the - messages in that folder, you must use view-file instead (bound to - space by default). - - · You can delete mailboxes with the delete-mailbox command (bound to - d by default. You may also subscribe and unsubscribe to mailboxes - (normally these are bound to s and u, respectively). - - 4.11.2. Authentication - - Mutt supports four authentication methods with IMAP servers: SASL, - GSSAPI, CRAM-MD5, and LOGIN (there is a patch by Grant Edwards to add - NTLM authentication for you poor exchange users out there, but it has - yet to be integrated into the main tree). There is also support for - the pseudo-protocol ANONYMOUS, which allows you to log in to a public - IMAP server without having an account. To use ANONYMOUS, simply make - your username blank or "anonymous". - - SASL is a special super-authenticator, which selects among several - protocols (including GSSAPI, CRAM-MD5, ANONYMOUS, and DIGEST-MD5) the - most secure method available on your host and the server. Using some - of these methods (including DIGEST-MD5 and possibly GSSAPI), your - entire session will be encrypted and invisible to those teeming - network snoops. It is the best option if you have it. To use it, you - must have the Cyrus SASL library installed on your system and compile - mutt with the --with-sasl flag. - - Mutt will try whichever methods are compiled in and available on the - server, in the following order: SASL, ANONYMOUS, GSSAPI, CRAM-MD5, - LOGIN. - - There are a few variables which control authentication: + unset user_foo - · ``$imap_user'' - controls the username under which you request - authentication on the IMAP server, for all authenticators. This is - overridden by an explicit username in the mailbox path (ie by using - a mailbox name of the form {user@host}). - - · ``$imap_pass'' - a password which you may preset, used by all - authentication methods where a password is needed. - - · ``$imap_authenticators'' - a colon-delimited list of IMAP - authentication methods to try, in the order you wish to try them. - If specified, this overrides mutt's default (attempt everything, in - the order listed above). - - 4.12. Managing multiple IMAP/POP accounts (OPTIONAL) + any query or operation (except the noted expansion within other statements) + will lead to an error message. - 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. - - Some examples: - - account-hook . 'unset imap_user; unset imap_pass; unset tunnel' - account-hook imap://host1/ 'set imap_user=me1 imap_pass=foo' - account-hook imap://host2/ 'set tunnel="ssh host2 /usr/libexec/imapd"' - - 4.13. Start a WWW Browser on URLs (EXTERNAL) - - If a message contains URLs (unified resource locator = address in the - WWW space like http://www.mutt.org/), it is efficient to get a menu - with all the URLs and start a WWW browser on one of them. This - functionality is provided by the external urlview program which can be - retrieved at ftp://ftp.mutt.org/mutt/contrib/ and the configuration - commands: - - macro index \cb |urlview\n - macro pager \cb |urlview\n - - 5. Mutt's MIME Support - - Quite a bit of effort has been made to make Mutt the premier text-mode - MIME MUA. Every effort has been made to provide the functionality - that the discerning MIME user requires, and the conformance to the - standards wherever possible. When configuring Mutt for MIME, there - are two extra types of configuration files which Mutt uses. One is - the mime.types file, which contains the mapping of file extensions to - IANA MIME types. The other is the mailcap file, which specifies the - external commands to use for handling specific MIME types. - - 5.1. Using MIME in Mutt - - There are three areas/menus in Mutt which deal with MIME, they are the - pager (while viewing a message), the attachment menu and the compose - menu. - - 5.1.1. Viewing MIME messages in the pager - - When you select a message from the index and view it in the pager, - Mutt decodes the message to a text representation. Mutt internally - supports a number of MIME types, including text/plain, text/enriched, - message/rfc822, and message/news. In addition, the export controlled - version of Mutt recognizes a variety of PGP MIME types, including - PGP/MIME and application/pgp. - - Mutt will denote attachments with a couple lines describing them. - These lines are of the form: - - [-- Attachment #1: Description --] - [-- Type: text/plain, Encoding: 7bit, Size: 10000 --] - - Where the Description is the description or filename given for the - attachment, and the Encoding is one of 7bit/8bit/quoted-print- - able/base64/binary. - - If Mutt cannot deal with a MIME type, it will display a message like: - - [-- image/gif is unsupported (use 'v' to view this part) --] - - 5.1.2. The Attachment Menu - - 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. - - Finally, you can apply the usual message-related functions (like - ``resend-message'', and the reply and forward functions) to - attachments of type message/rfc822. - - See the help on the attachment menu for more information. - - 5.1.3. The Compose Menu - - The compose menu is the menu you see before you send a message. It - allows you to edit the recipient list, the subject, and other aspects - of your message. It also contains a list of the attachments of your - message, including the main body. From this menu, you can print, - copy, filter, pipe, edit, compose, review, and rename an attachment or - a list of tagged attachments. You can also modifying the attachment - information, notably the type, encoding and description. - - Attachments appear as follows: - - - 1 [text/plain, 7bit, 1K] /tmp/mutt-euler-8082-0 - 2 [applica/x-gunzip, base64, 422K] ~/src/mutt-0.85.tar.gz - - The '-' denotes that Mutt will delete the file after sending (or - postponing, or cancelling) the message. It can be toggled with the - toggle-unlink command (default: u). The next field is the MIME - content-type, and can be changed with the edit-type command (default: - ^T). The next field is the encoding for the attachment, which allows - a binary message to be encoded for transmission on 7bit links. It can - be changed with the edit-encoding command (default: ^E). The next - field is the size of the attachment, rounded to kilobytes or - megabytes. The next field is the filename, which can be changed with - the rename-file command (default: R). The final field is the - description of the attachment, and can be changed with the edit- - description command (default: d). - - 5.2. MIME Type configuration with mime.types - - When you add an attachment to your mail message, Mutt 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 - - The mime.types file consist of lines containing a MIME type and a - space separated list of extensions. For example: - - application/postscript ps eps - application/pgp pgp - audio/x-aiff aif aifc aiff - - A sample mime.types file comes with the Mutt distribution, and should - contain most of the MIME types you are likely to use. - - If Mutt 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 will assume that the file is plain text, and mark it - as text/plain. If the file contains binary information, then Mutt - will mark it as application/octet-stream. You can change the MIME - type that Mutt 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 recognises all of these if - the appropriate entry is found in the mime.types file. It also - recognises other major mime types, such as the chemical type that is - widely used in the molecular modelling community to pass molecular - data in various forms to various molecular viewers. Non-recognised - mime types should only be used if the recipient of the message is - likely to be expecting such attachments. - - 5.3. MIME Viewer configuration with mailcap - - Mutt 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. - - In order to handle various MIME types that Mutt can not handle - internally, Mutt parses a series of external configuration files to - find an external handler. The default search string for these files - is a colon delimited list set to - - ${HOME}/.mailcap:/usr/local/share/mutt/mailcap:/etc/mailcap:/etc/mailcap:/usr/etc/mailcap:/usr/local/etc/mailcap - - where $HOME is your home directory. - - In particular, the metamail distribution will install a mailcap file, - usually as /usr/local/etc/mailcap, which contains some baseline - entries. - - 5.3.1. The Basics of the mailcap file - - A mailcap file consists of a series of lines which are comments, - blank, or definitions. - - A comment line consists of a # character followed by anything you - want. - - A blank line is blank. - - 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. - - The content type is specified in the MIME standard type/subtype - method. For example, text/plain, text/html, image/gif, etc. In - addition, the mailcap format includes two formats for wildcards, one - using the special '*' subtype, the other is the implicit wild, where - you only include the major type. For example, image/*, or video, will - match all image types and video types, respectively. - - The view command is a Unix command for viewing the type specified. - There are two different types of commands supported. The default is to - send the body of the MIME message to the command on stdin. You can - change this behaviour by using %s as a parameter to your view command. - This will cause Mutt 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 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. - - So, in the simplest form, you can send a text/plain message to the - external pager more on stdin: - - text/plain; more - - Or, you could send the message as a file: - - text/plain; more %s - - Perhaps you would like to use lynx to interactively view a text/html - message: - - text/html; lynx %s - - In this case, lynx does not support viewing a file from stdin, so you - must use the %s syntax. Note: Some older versions of lynx contain a - bug where they will check the mailcap file for a viewer for text/html. - They will find the line which calls lynx, and run it. This causes - lynx to continuously spawn itself to view the object. - - On the other hand, maybe you don't want to use lynx interactively, you - just want to have it convert the text/html to text/plain, then you can - use: - - text/html; lynx -dump %s | more - - Perhaps you wish to use lynx to view text/html files, and a pager on - all other text formats, then you would use the following: - - text/html; lynx %s - text/*; more - - This is the simplest form of a mailcap file. - 5.3.2. Secure use of mailcap - - The interpretion of shell meta-characters embedded in MIME parameters - can lead to security problems in general. Mutt tries to quote - parameters in expansion of %s syntaxes properly, and avoids risky - characters by substituting them, see the ``mailcap_sanitize'' - variable. - - 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: - - Keep the %-expandos away from shell quoting. Don't quote them with - single or double quotes. Mutt does this for you, the right way, as - should any other program which interprets mailcap. Don't put them - into backtick expansions. Be highly careful with eval statements, and - avoid them if possible at all. Trying to fix broken behaviour with - quotes introduces new leaks - there is no alternative to correct - quoting in the first place. - - If you have to use the %-expandos' values in context where you need - quoting or backtick expansions, put that value into a shell variable - and reference the shell variable where necessary, as in the following - example (using $charset inside the backtick expansion is safe, since - it is not itself subject to any further expansion): - - text/test-mailcap-bug; cat %s; copiousoutput; test=charset=%{charset} \ - && test "`echo $charset | tr '[A-Z]' '[a-z]'`" != iso-8859-1 - - 5.3.3. Advanced mailcap Usage - - 5.3.3.1. Optional Fields - - In addition to the required content-type and view command fields, you - can add semi-colon ';' separated fields to set flags and other - options. Mutt recognizes the following optional fields: - - copiousoutput - This flag tells Mutt that the command passes possibly large - amounts of text on stdout. This causes Mutt to invoke a pager - (either the internal pager or the external pager defined by the - pager variable) on the output of the view command. Without this - flag, Mutt assumes that the command is interactive. One could - use this to replace the pipe to more in the lynx -dump example - in the Basic section: - - text/html; lynx -dump %s ; copiousoutput - - This will cause lynx to format the text/html output as text/plain - and Mutt will use your standard pager to display the results. - - needsterminal - Mutt uses this flag when viewing attachments with ``autoview'', - in order to decide whether it should honor the setting of the - ``$wait_key'' variable or not. When an attachment is viewed - using an interactive program, and the corresponding mailcap - entry has a needsterminal flag, Mutt will use ``$wait_key'' and - the exit status of the program to decide if it will ask you to - press a key after the external program has exited. In all other - situations it will not prompt you for a key. - - compose= - This flag specifies the command to use to create a new - attachment of a specific MIME type. Mutt supports this from the - compose menu. - - composetyped= - This flag specifies the command to use to create a new - attachment of a specific MIME type. This command differs from - the compose command in that mutt will expect standard MIME - headers on the data. This can be used to specify parameters, - filename, description, etc. for a new attachment. Mutt - supports this from the compose menu. - - print= - This flag specifies the command to use to print a specific MIME - type. Mutt supports this from the attachment and compose menus. - - edit= - This flag specifies the command to use to edit a specific MIME - type. Mutt supports this from the compose menu, and also uses - it to compose new attachments. Mutt will default to the defined - editor for text attachments. - - nametemplate=
