Each individual mailcap entry consists of a content-type specification, a command to execute, and (possibly) a set of optional "flag" values.

The "type" field is simply any legal content type name. It is the string that will be matched against the ''Content-Type:'' header to decide if this is the mailcap entry that matches the current message. Additionally, the type field may specify a subtype or a wildcard to match all subtypes.

The "command" field is any UNIX command and is used to specify the interpreter for the given type of message. It will be passed to the shell via the system(3) facility.

Semicolons and backslashes within the command or any flag field must be quoted with backslashes. If the field contains "%s", those two characters will be replaced by the name of a file that contains the body of the message. If it contains "%t", those two characters will be replaced by the content-type field, including the subtype, if any. If it contains "%{" followed by a parameter name and a closing "}", then all those characters will be replaced by the value of the named parameter, if any, from the ''Content-Type:'' header. Finally, if the field contains "\%", those two characters will be replaced by a single "%" character.

Besides the type and command field the following "flags" are defined:

compose

The "compose" field may be used to specify a program that can be used to compose a new body or body part in the given format. Its intended use is to support mail composing agents that support the composition of multiple types of mail using external composing agents. As with the view-command, the semantics of program execution are operating system dependent. The result of the composing program may be data that is not yet suitable for mail transport — that is, a Content-Transfer-Encoding may need to be applied to the data.

composetyped

The "composetyped" field is similar to the "compose" field, but is to be used when the composing program needs to specify the ''Content-Type:'' header field to be applied to the composed data. The "compose" field is simpler, and is preferred for use with existing (non-mail-oriented) programs for composing data in a given format. The "composetyped" field is necessary when the Content-Type information must include auxiliary parameters, and the composition program must then know enough about mail formats to produce output that includes the mail type information.

edit

The "edit" field may be used to specify a program that can be used to edit a body or body part in the given format. In many cases, it may be identical in content to the "compose" field, and shares the operating-system dependent semantics for program execution.

print

The "print" field may be used to specify a program that can be used to print a message or body part in the given format. As with the view-command, the semantics of program execution are operating system dependent.

test

The "test" field may be used to test some external condition (e.g., the machine architecture, or the window system in use) to determine whether or not the mailcap line applies. It specifies a program to be run to test some condition. The semantics of execution and of the value returned by the test program are operating system dependent. If the test fails, a subsequent mailcap entry should be sought. Multiple test fields are not permitted — since a test can call a program, it can already be arbitrarily complex.

needsterminal

The "needsterminal" field indicates that the view-command must be run on an interactive terminal. This is needed to inform window-oriented user agents that an interactive terminal is needed. (The decision is not left exclusively to the view-command because in some circumstances it may not be possible for such programs to tell whether or not they are on interactive terminals.) The needsterminal command should be assumed to apply to the compose and edit commands, too, if they exist. Note that this is NOT a test - it is a requirement for the environment in which the program will be executed, and should typically cause the creation of a terminal window when not executed on either a real terminal or a terminal window.

copiousoutput

The "copiousoutput" field indicates that the output from the view-command will be an extended stream of output, and is to be interpreted as advice to the UA (User Agent mail-reading program) that the output should be either paged or made scroll-able. Note that it is probably a mistake if needsterminal and copiousoutput are both specified.

description

The "description" field simply provides a textual description, optionally quoted, that describes the type of data, to be used optionally by mail readers that wish to describe the data before offering to display it.

textualnewlines

The "textualnewlines" field, if set to any non-zero value, indicates that this type of data is line-oriented and that, if encoded in base64, all newlines should be converted to canonical form (CRLF) before encoding, and will be in that form after decoding. In general, this field is needed only if there is line-oriented data of some type other than text/* or non-line- oriented data that is a subtype of text.

x11-bitmap

The "x11-bitmap" field names a file, in X11 bitmap (xbm) format, which points to an appropriate icon to be used to visually denote the presence of this kind of data.

nametemplate

The "nametemplate" field gives a filename format, in which %s will be replaced by a short unique string to give the name of the temporary file to be passed to the viewing command. This is only expected to be relevant in environments where filename extensions are meaningful, e.g., one could specify that a GIF file being passed to a gif viewer should have a name ending in ".gif" by using "nametemplate=%s.gif"

tin(1) currently only respects the "test", "description", "nametemplate" and partly the "needsterminal" flags, all other flags are internally ignored. It also can't handle the "%F" and "%n" expansions yet.

Example:

# mailcap file example


image/*;\




xv -8 -geometry +0 '%s';\


description=%{name} %t-Image;\


test=test "$DISPLAY" != "";\


nametemplate=%s.IMAGE



message/rfc822;\




${PAGER:-"more"} '%s';\


edit=${EDITOR:-"vi"} '%s';\


compose=${EDITOR:-"vi"} '%s';\


print=a2ps '%s';\


needsterminal

nntpserver

full qualified domain name of the news server. Additionally, a port can be specified by appending :portnumber.

password

user's unencrypted password for reading news.

user

username on the news server if it differs from the local login. This field is optional.

Example:

newsgroup

the name of the newsgroup.

flag

a flag indicating if the group is subscribed ':' or not '!'.

article

range of already read articles from that group; numbers separated by commas with sequential numbers collapsed with hyphens. Empty lines and lines which start with "#" are ignored and not written back.

Example:

mailgroupname

must be the pathname of the mailbox relative to field #4 with '/' changed to '.'

maxnum

just put a large number here, something higher than the highest message in the mailbox

minnum

put 0 here

mailspool

path of mail spool directory. This must be the full pathname to the root of the mail folder area.

Example:

This allows access to the 'inbox' and 'outbox' folders of user foo. They are accessed via /home/foo/Mail/inbox and /home/foo/Mail/outbox

scope

This changes the list of groups to which the attributes that follow will be applied. See the section NEWSGROUP LISTS & WILDCARDS in tin(1) for the types of pattern that can be used here.

add_posted_to_filter

Identical to the tinrc variable of the same name

advertising

Identical to the tinrc variable of the same name

alternative_handling

Identical to the tinrc variable of the same name

ask_for_metamail

Identical to the tinrc variable of the same name

auto_cc_bcc

Identical to the tinrc variable of the same name

auto_list_thread

Identical to the tinrc variable of the same name

auto_select

Automatically perform the GroupMarkUnselArtRead ('X') command after entering the group.

batch_save

Can be used to override the global setting in tinrc on a per group basis. For more information read section AUTOMATIC MAILING AND SAVING NEW NEWS in tin(1).

date_format

Identical to the tinrc variable of the same name

delete_tmp_files

If this is set to ON, then saved article files that have been post-processed will be automatically deleted, otherwise the user will be asked whether to delete the post-processed files. Automatic processing of marked articles using GroupAutoSave ('S') will suppress prompting.

editor_format

Identical to the tinrc variable of the same name

extquote_handling

Identical to the tinrc variable of the same name

fcc

Mailbox to save sent mails. The format of the mailbox is controlled via the tinrc mailbox_format variable.

Used when a group is a mailing list. All responses to the group will be directed to this email address instead

mark_ignore_tags

Identical to the tinrc variable of the same name

mark_saved_read

Identical to the tinrc variable of the same name

mime_forward

Determines whether usenet articles are forwarded as attachment or inline. When set to OFF, the forwarded article will be included in the body of the mail, while setting this variable to ON will cause the article to be attached as a separate MIME part. Enabling mime_forward is particularly useful for articles consisting of multiple MIME parts such as PGP/MIME signed messages or being encoded in a different character set than your local one. It is also useful if the receiver should be able to operate on the entire forwarded article (i.e., view or save it without your comments). On the other hand, if you want to forward only some parts of the article or to insert 'inline' annotations, you might want to disable this option. Currently mime_forward is forced if the article to be attached is a multipart MIME article, this may change in a future version. Please note that for this option to have effect, the tinrc variable interactive_mailer has to be set to 0 (which is the default).

mime_types_to_save

A comma separated list of MIME major/minor Content-Types that will be saved when using the view/save and save/autosave features. A single * can be used to wildcard the major and/or minor type and a ! as the first character in an entry will negate it, eg: image/*,!image/bmp,!text/html. Default is */*

mm_network_charset

Identical to the tinrc variable of the same name

undeclared_charset

Assume (broken) articles without MIME charset declaration have this charset — default is US-ASCII. This attribute works only on systems with working iconv(3), others might have to compile tin(1) with --disable-mime-strict-charset.

undeclared_cs_guess

Guess charset for (broken) articles without MIME charset declaration. This attribute works only on systems with working iconv(3) and ucsdet_getName(3) from libicui18n. It has no effect if undeclared_charset is also set.

Example:

# include extra headers
# assume ISO-8859-1 as charset if no charset is declared
# in all but fido7.* groups
scope=*,!fido7.*
x_headers=~/.tin/headers
undeclared_charset=ISO-8859-1
# in *sources* set post process type to shar only
scope=*sources*
post_process_type=1
# in *binaries* turn on full post processing,
# remove tmp files and set Followup-To: poster
scope=*binaries*
post_process_type=2
delete_tmp_files=ON
followup_to=poster
# in fido.* newsgroups change quote_chars
# and add X-Comment-To: line
scope=fido.*
quote_chars=%I>_
x_comment_to=ON
# in fido7.* newsgroups guess charset
scope=fido7.*
undeclared_cs_guess=ON
# in *.test newsgroups, don't append signature
# and preset Subject
scope=*.test
sigfile=--none
x_headers=Subject: test - ignore - no reply
# assume ISO-2022-JP-2 as charset
scope=fj.*,japan.*
undeclared_charset=ISO-2022-JP-2

comment

Every entry (rule) in the filter file might get a comment. Multiple lines are allowed (but only for comments yet). Every line must start with the "comment=" keyword. Comments must appear first in the rule. Comment lines placed within a rule will be moved to the begin of the next rule. This might be changed in the future. Don't use '#' to mark comments as those lines are ignored and your comments will get lost on the next write of the file.

group

A comma-separated list of newsgroup patterns in wildmat-style to which groups the filter rule will be applied. This line is mandatory!

case

0=case-sensitive, 1=case-insensitive

score

Score value of the rule; can also be one of the magic words "kill" or "hot".

subj

Match against ''Subject:''. The matching type used (wildmat or regex) depends on the setting of the tinrc variable wildcard.

from

Match against ''From:''. tin(1) converts the contents of the ''From:'' header to an old style e-mail address, e.g. ''some@body.example (John Doe)'' instead of ''John Doe <some@body.example>'', before trying to match the patterns in the filter rule. The matching type used (wildmat or regex) depends on the setting of the tinrc variable wildcard.

msgid

Match against ''Message-ID:'' and full ''References:''. The matching type used (wildmat or regex) depends on the setting of the tinrc variable wildcard.

msgid_last

Match against ''Message-ID:'' and last ''References:'' entry (direct responses) only. The matching type used (wildmat or regex) depends on the setting of the tinrc variable wildcard.

msgid_only

Match against ''Message-ID:''. The matching type used (wildmat or regex) depends on the setting of the tinrc variable wildcard.

refs_only

Match against ''References:''. The matching type used (wildmat or regex) depends on the setting of the tinrc variable wildcard.

lines

Match against ''Lines:'', <num matches less than, >num matches more than.

gnksa

Match against ''From:'' address parser return codes. <num matches less than, >num matches more than the returned numeric value. GNKSA_LOCAL_DOMAIN_LITERAL or GNKSA_INVALID_DOMAIN are only returned if disable_gnksa_domain_check is set to false. As the built in domain list is outdated this should be considered carefully.

  0	GNKSA_OK
  1	GNKSA_INTERNAL_ERROR
100	GNKSA_LANGLE_MISSING
101	GNKSA_LPAREN_MISSING
102	GNKSA_RPAREN_MISSING

205	GNKSA_ZERO_LENGTH_LABEL
206	GNKSA_ILLEGAL_LABEL_LENGTH
207	GNKSA_ILLEGAL_LABEL_HYPHEN
208	GNKSA_ILLEGAL_LABEL_BEGNUM
209	GNKSA_BAD_DOMAIN_LITERAL
210	GNKSA_LOCAL_DOMAIN_LITERAL
211	GNKSA_RBRACKET_MISSING
300	GNKSA_LOCALPART_MISSING
301	GNKSA_INVALID_LOCALPART
302	GNKSA_ZERO_LENGTH_LOCAL_WORD
400	GNKSA_ILLEGAL_UNQUOTED_CHAR
401	GNKSA_ILLEGAL_QUOTED_CHAR
402	GNKSA_ILLEGAL_ENCODED_CHAR
403	GNKSA_BAD_ENCODE_SYNTAX
404	GNKSA_ILLEGAL_PAREN_CHAR
405	GNKSA_INVALID_REALNAME
406	GNKSA_MISSING_REALNAME

xref

Match against ''Xref:'' line. Before any matching is done the line is turned into the same format ''Newsgroups:'' has that is it is turned into a comma separated newsgroup list with all other information (i.e. the article counter) removed. The matching type used (wildmat or regex) depends on the setting of the tinrc variable wildcard.

path

Match against ''Path:'' line. This may not work on some servers. The matching type used (wildmat or regex) depends on the setting of the tinrc variable wildcard.

time

time_t value when rule expires

Example:

comment=mark all articles about tin, rtin,
comment=tind, ktin or cdtin as hot
group=*
case=1
score=hot
subj=\b(cd|[rk]?)?tin(d|pre)?[-.0-9]*\b
comment=downscore postings in nsr from google based on
comment=message-id or path, if both hit they end up with
comment=a score of -66 which is enough to mark them killed
group=news.software.readers
case=1
score=-33
path=\.googlegroups\.com!not-for-mail$
msgid_only=@googlegroups\.com>

nntpserver

full qualified domain name of the news server. Plain IPv6 address must be enclosed in square brackets. Additionally, a port can be specified by appending :portnumber. Be aware that if a port is given it will override any port given with ''-g'' or ''-p'' or implied by ''-T'' or ''-k'' or set via $NNTPPORT. The string "default" or "*" acts as wildcard to match any name, such a line should be placed last.

sendmail -oem -t < %F
mutt -H %F
claws-mail --compose "mailto:%T?subject=%S&insert=%F"

interactive_mailer must be set adequate. The following substitutions are supported:

If MIME_STRICT_CHARSET is defined at compile time, text in charset other than the value of this parameter is considered not displayable and represented as '?'. Otherwise, all character sets are regarded as compatible with the display. If it's not set, the value of the environment variable $MM_CHARSET is used. US-ASCII or compile-time default is used in case neither of them is defined. If your system supports iconv(3), this option is disabled and you should use mm_network_charset instead.

mm_network_charset

Charset used for posting and MIME headers; replaces mm_charset. Conversion between mm_network_charset and local charset (determined via nl_langinfo(3)) is done via iconv(3), if this function is not available on your system this option is disabled and you have to use mm_charset instead. mm_network_charset is limited to one of the following charsets:
US-ASCII, ISO-8859-{1,2,3,4,5,7,9,10,13,14,15,16}, KOI8-{R,U,RU} EUC-{CN,JP,KR,TW}, ISO-2022-{CN,CN-EXT,JP,JP-1,JP-2}, Big5, UTF-8
Not all values might work on your system, see iconv_open(3) for more details. If it's not set, the value of the environment variable $MM_CHARSET is used. US-ASCII or compile-time default is used in case neither of them is defined.

If you enter 'X-' as the value, you will see all headers beginning with 'X-' (like X-Alan or X-Pape). You can list more than one by delimiting with spaces. Not defining anything turns off this option.

news_headers_to_not_display

Same as news_headers_to_display except it denotes the opposite. An example of using both options might be if you thought 'X-' headers were A Good Thing(tm), but thought Alan and Pape were miscreants... well then you would do something like this: news_headers_to_display=X- news_headers_to_not_display=X-Alan X-Pape Not defining anything turns off this option.

news_quote_format

Only enacted if post_mime_encoding is also set to 8bit. In a number of local hierarchies where 8bit characters are used, using unencoded (raw) 8bit characters in header is acceptable and sometimes even recommended so that you need to check the convention adopted in the local hierarchy of your interest to determine what to do with this and post_mime_encoding.

post_mime_encoding

MIME encoding of the body in news message, if necessary. (8bit, base64, quoted-printable, 7bit). Default is 8bit, which leads to no encoding. base64 and quoted-printable are usually undesired on usenet.
