@node New Mail Message
@section New Mail Message
This function will be called narrowed to the head of the article that is
being replied to.
-As you can see, this function should return a string if it has an
-opinion as to what the To header should be. If it does not, it should
-just return @code{nil}, and the normal methods for determining the To

+returns @code{((To . "Whom"))} if it has an opinion as to what the To
+header should be. If it does not, it should just return @code{nil}, and
+the normal methods for determining the To header will be used.
-This function can also return a list. In that case, each list element
-should be a cons, where the car should be the name of an header
-(eg. @code{Cc}) and the cdr should be the header value
-(eg. @samp{larsi@@ifi.uio.no}). All these headers will be inserted into
-the head of the outgoing mail.
+Each list element should be a cons, where the @sc{car} should be the

+value (e.g. @samp{larsi@@ifi.uio.no}). All these headers will be
+inserted into the head of the outgoing mail.
@node Wide Reply
@code{message-wide-reply-to-function}. It is used in the same way as
@code{message-reply-to-function} (@pxref{Reply}).
-@findex message-dont-reply-to-names
+@vindex message-dont-reply-to-names
Addresses that match the @code{message-dont-reply-to-names} regular
-expression will be removed from the @code{Cc} header.
+expression (or list of regular expressions) will be removed from the
+@code{Cc} header. A value of @code{nil} means exclude your name only.
+
+@vindex message-prune-recipient-rules
+@code{message-prune-recipient-rules} is used to prune the addresses
+used when doing a wide reply. It's meant to be used to remove
+duplicate addresses and the like. It's a list of lists, where the
+first element is a regexp to match the address to trigger the rule,
+and the second is a regexp that will be expanded based on the first,
+to match addresses to be pruned.
+
+It's complicated to explain, but it's easy to use.
+For instance, if you get an email from @samp{foo@@example.org}, but
+@samp{foo@@zot.example.org} is also in the @code{Cc} list, then your
+wide reply will go out to both these addresses, since they are unique.
+
+To avoid this, do something like the following:
+
+@lisp
+(setq message-prune-recipient-rules
+ '(("^\\([^@@]+\\)@@\\(.*\\)" "\\1@@.*[.]\\2")))
+@end lisp
+
+If, for instance, you want all wide replies that involve messages from
+@samp{cvs@@example.org} to go to that address, and nowhere else (i.e.,
+remove all other recipients if @samp{cvs@@example.org} is in the
+recipient list:
+
+@lisp
+(setq message-prune-recipient-rules
+ '(("cvs@@example.org" ".")))
+@end lisp
+
+@vindex message-wide-reply-confirm-recipients
+If @code{message-wide-reply-confirm-recipients} is non-@code{nil} you
+will be asked to confirm that you want to reply to multiple
+recipients. The default is @code{nil}.
@node Followup
@section Followup
The @code{message-cancel-news} command cancels the article in the
current buffer.
+@vindex message-cancel-message
+The value of @code{message-cancel-message} is inserted in the body of
+the cancel message. The default is @samp{I am canceling my own
+article.}.
+
+@cindex Cancel Locks
+@vindex message-insert-canlock
+@cindex canlock
+When Message posts news messages, it inserts @code{Cancel-Lock}
+headers by default. This is a cryptographic header that ensures that
+only you can cancel your own messages, which is nice. The downside
+is that if you lose your @file{.emacs} file (which is where Gnus
+stores the secret cancel lock password (which is generated
+automatically the first time you use this feature)), you won't be
+able to cancel your message. If you want to manage a password yourself,
+you can put something like the following in your @file{~/.gnus.el} file:
+
+@lisp
+(setq canlock-password "geheimnis"
+ canlock-password-for-verify canlock-password)
+@end lisp
+
+Whether to insert the header or not is controlled by the
+@code{message-insert-canlock} variable.
+
+Not many news servers respect the @code{Cancel-Lock} header yet, but
+this is expected to change in the future.
+
@node Superseding
@section Superseding
Headers matching the @code{message-ignored-supersedes-headers} are
removed before popping up the new message buffer. The default is@*
@samp{^Path:\\|^Date\\|^NNTP-Posting-Host:\\|^Xref:\\|^Lines:\\|@*

+@node Mailing Lists
+@section Mailing Lists
+
+@cindex Mail-Followup-To
+Sometimes while posting to mailing lists, the poster needs to direct
+followups to the post to specific places. The Mail-Followup-To (MFT)
+was created to enable just this. Three example scenarios where this is
+useful:
+
+@itemize @bullet
+@item
+A mailing list poster can use MFT to express that responses should be
+sent to just the list, and not the poster as well. This will happen
+if the poster is already subscribed to the list.
+
+@item
+A mailing list poster can use MFT to express that responses should be
+sent to the list and the poster as well. This will happen if the poster
+is not subscribed to the list.
+
+@item
+If a message is posted to several mailing lists, MFT may also be used
+to direct the following discussion to one list only, because
+discussions that are spread over several lists tend to be fragmented
+and very difficult to follow.
+
+@end itemize
+
+Gnus honors the MFT header in other's messages (i.e. while following
+up to someone else's post) and also provides support for generating
+sensible MFT headers for outgoing messages as well.

+@c @end menu
+
+@c @node Composing with a MFT header
+@subsection Composing a correct MFT header automagically
+
+The first step in getting Gnus to automagically generate a MFT header
+in posts you make is to give Gnus a list of the mailing lists
+addresses you are subscribed to. You can do this in more than one
+way. The following variables would come in handy.
+
+@table @code
+
+@vindex message-subscribed-addresses
+@item message-subscribed-addresses
+This should be a list of addresses the user is subscribed to. Its
+default value is @code{nil}. Example:
+@lisp
+(setq message-subscribed-addresses
+ '("ding@@gnus.org" "bing@@noose.org"))
+@end lisp
+
+@vindex message-subscribed-regexps
+@item message-subscribed-regexps
+This should be a list of regexps denoting the addresses of mailing
+lists subscribed to. Default value is @code{nil}. Example: If you
+want to achieve the same result as above:
+@lisp
+(setq message-subscribed-regexps
+ '("\\(ding@@gnus\\)\\|\\(bing@@noose\\)\\.org")
+@end lisp
+
+@vindex message-subscribed-address-functions
+@item message-subscribed-address-functions
+This can be a list of functions to be called (one at a time!!) to
+determine the value of MFT headers. It is advisable that these
+functions not take any arguments. Default value is @code{nil}.
+There is a pre-defined function in Gnus that is a good candidate for
+this variable. @code{gnus-find-subscribed-addresses} is a function
+that returns a list of addresses corresponding to the groups that have
+the @code{subscribed} (@pxref{Group Parameters, ,Group Parameters,
+gnus, The Gnus Manual}) group parameter set to a non-@code{nil} value.
+This is how you would do it.
+
+@lisp
+(setq message-subscribed-address-functions
+ '(gnus-find-subscribed-addresses))
+@end lisp
+
+@vindex message-subscribed-address-file
+@item message-subscribed-address-file
+You might be one organized human freak and have a list of addresses of
+all subscribed mailing lists in a separate file! Then you can just
+set this variable to the name of the file and life would be good.
+
+@end table
+
+You can use one or more of the above variables. All their values are
+``added'' in some way that works :-)
+
+Now you are all set. Just start composing a message as you normally do.
+And just send it; as always. Just before the message is sent out, Gnus'
+MFT generation thingy kicks in and checks if the message already has a
+MFT field. If there is one, it is left alone. (Except if it's empty -
+in that case, the field is removed and is not replaced with an
+automatically generated one. This lets you disable MFT generation on a
+per-message basis.) If there is none, then the list of recipient
+addresses (in the To: and Cc: headers) is checked to see if one of them
+is a list address you are subscribed to. If none of them is a list
+address, then no MFT is generated; otherwise, a MFT is added to the
+other headers and set to the value of all addresses in To: and Cc:
+
+@kindex C-c C-f C-a
+@findex message-generate-unsubscribed-mail-followup-to
+@kindex C-c C-f C-m
+@findex message-goto-mail-followup-to
+Hm. ``So'', you ask, ``what if I send an email to a list I am not
+subscribed to? I want my MFT to say that I want an extra copy.'' (This
+is supposed to be interpreted by others the same way as if there were no
+MFT, but you can use an explicit MFT to override someone else's
+to-address group parameter.) The function
+@code{message-generate-unsubscribed-mail-followup-to} might come in
+handy. It is bound to @kbd{C-c C-f C-a} by default. In any case, you
+can insert a MFT of your own choice; @kbd{C-c C-f C-m}
+(@code{message-goto-mail-followup-to}) will help you get started.
+
+@c @node Honoring an MFT post
+@subsection Honoring an MFT post
+
+@vindex message-use-mail-followup-to
+When you followup to a post on a mailing list, and the post has a MFT
+header, Gnus' action will depend on the value of the variable
+@code{message-use-mail-followup-to}. This variable can be one of:
+
+@table @code
+@item use
+ Always honor MFTs. The To: and Cc: headers in your followup will be
+ derived from the MFT header of the original post. This is the default.
+
+@item nil
+ Always dishonor MFTs (just ignore the darned thing)
+
+@item ask
+Gnus will prompt you for an action.
+
+@end table
+
+It is considered good netiquette to honor MFT, as it is assumed the
+fellow who posted a message knows where the followups need to go
+better than you do.

To be able to send encrypted mail, a personal certificate is not
-required. Message (MML) need a certificate for the person to whom you
+required. Message (@acronym{MML}) need a certificate for the person to whom you
wish to communicate with though. You're asked for this when you type
-@code{C-c C-m c s}. Currently there are two ways to retrieve this
-certificate, from a local file or from DNS. If you chose a local file,
-it need to contain a X.509 certificate in PEM format. If you chose DNS,
-you're asked for the domain name where the certificate is stored, the
-default is a good guess. To my belief, Message (MML) is the first mail
-agent in the world to support retrieving S/MIME certificates from DNS,
-so you're not likely to find very many certificates out there. At least
-there should be one, stored at the domain @code{simon.josefsson.org}.

As for signing messages, OpenSSL can't perform signing operations
without some kind of configuration. Especially, you need to tell it

-Emacs interface to OpenSSL, aptly named @code{smime.el}, and it contain
-a @code{custom} group used for this configuration. So, try @code{M-x

-with OpenSSL or using some other program. I used Netscape and got a

+@node Using PGP/MIME
@subsection Using PGP/MIME
-PGP/MIME requires an external OpenPGP implementation, such as GNU
-Privacy Guard (@uref{http://www.gnupg.org/}). It also requires an Emacs
-interface to it, such as Mailcrypt (available from
-@url{http://www.nb.net/~lbudney/linux/software/mailcrypt.html}) or
-Florian Weimer's @code{gpg.el}.
+@acronym{PGP/MIME} requires an external OpenPGP implementation, such
+as @uref{http://www.gnupg.org/, GNU Privacy Guard}. Pre-OpenPGP
+implementations such as PGP 2.x and PGP 5.x are also supported. One
+Emacs interface to the PGP implementations, PGG (@pxref{Top, ,PGG,
+pgg, PGG Manual}), is included, but Mailcrypt is also supported.
+@xref{PGP Compatibility}.
+
+@cindex gpg-agent
+Message internally calls GnuPG (the @command{gpg} command) to perform
+data encryption, and in certain cases (decrypting or signing for
+example), @command{gpg} requires user's passphrase. Currently the
+recommended way to supply your passphrase to @command{gpg} is to use the
+@command{gpg-agent} program.
+
+To use @command{gpg-agent} in Emacs, you need to run the following
+command from the shell before starting Emacs.
+
+@example
+eval `gpg-agent --daemon`
+@end example
+
+This will invoke @command{gpg-agent} and set the environment variable
+@code{GPG_AGENT_INFO} to allow @command{gpg} to communicate with it.
+It might be good idea to put this command in your @file{.xsession} or
+@file{.bash_profile}. @xref{Invoking GPG-AGENT, , , gnupg, Using the
+GNU Privacy Guard}.
+
+Once your @command{gpg-agent} is set up, it will ask you for a
+passphrase as needed for @command{gpg}. Under the X Window System,
+you will see a new passphrase input dialog appear. The dialog is
+provided by PIN Entry (the @command{pinentry} command), and as of
+version 0.7.2, @command{pinentry} cannot cooperate with Emacs on a
+single tty. So, if you are using a text console, you may need to put
+a passphrase into gpg-agent's cache beforehand. The following command
+does the trick.
+
+@example
+gpg --use-agent --sign < /dev/null > /dev/null
+@end example
+
+The Lisp variable @code{pgg-gpg-use-agent} controls whether to use
+@command{gpg-agent}. See also @xref{Caching passphrase, , , pgg, The
+PGG Manual}.
+
+
+@node PGP Compatibility
+@subsection Compatibility with older implementations
+
+@vindex gpg-temp-directory
+Note, if you are using the @code{gpg.el} you must make sure that the
+directory specified by @code{gpg-temp-directory} have permissions
+0700.
+
+Creating your own key is described in detail in the documentation of
+your PGP implementation, so we refer to it.
+
+If you have imported your old PGP 2.x key into GnuPG, and want to send
+signed and encrypted messages to your fellow PGP 2.x users, you'll
+discover that the receiver cannot understand what you send. One
+solution is to use PGP 2.x instead (i.e., if you use @code{pgg}, set
+@code{pgg-default-scheme} to @code{pgp}). You could also convince your
+fellow PGP 2.x users to convert to GnuPG.
+@vindex mml-signencrypt-style-alist
+As a final workaround, you can make the sign and encryption work in
+two steps; separately sign, then encrypt a message. If you would like
+to change this behavior you can customize the
+@code{mml-signencrypt-style-alist} variable. For example:
+
+@lisp
+(setq mml-signencrypt-style-alist '(("smime" separate)
+ ("pgp" separate)
+ ("pgpauto" separate)
+ ("pgpmime" separate)))
+@end lisp

@section Message Headers
Message is quite aggressive on the message generation front. It has to
-be -- it's a combined news and mail agent. To be able to send combined
+be---it's a combined news and mail agent. To be able to send combined
messages, it has to generate all headers itself (instead of letting the
mail/news system do it) to ensure that mail and news copies of messages
look sufficiently similar.

Note that some headers will be removed and re-generated before posting,
because of the variable @code{message-deletable-headers} (see below).

@item message-subject-re-regexp
@vindex message-subject-re-regexp
+@cindex Aw

+@cindex Re
Responses to messages have subjects that start with @samp{Re: }. This
is @emph{not} an abbreviation of the English word ``response'', but is
Latin, and means ``in response to''. Some illiterate nincompoops have
failed to grasp this fact, and have ``internationalized'' their software
-to use abonimations like @samp{Aw: } (``antwort'') or @samp{Sv: }
+to use abominations like @samp{Aw: } (``antwort'') or @samp{Sv: }
(``svar'') instead, which is meaningless and evil. However, you may
have to deal with users that use these evil tools, in which case you may
set this variable to a regexp that matches these prefixes. Myself, I
just throw away non-compliant mail.
+Here's an example of a value to deal with these headers when
+responding to a message:
+
+@lisp

+@item message-strip-special-text-properties
+@vindex message-strip-special-text-properties
+Emacs has a number of special text properties which can break message
+composing in various ways. If this option is set, message will strip
+these properties from the message composition buffer. However, some
+packages requires these properties to be present in order to work. If
+you use one of these packages, turn this option off, and hope the
+message composition doesn't break too bad.

-(TYPE PREDICATE FUNCTION)
+(@var{type} @var{predicate} @var{function})
@end lisp
@table @var
@item predicate
A function called without any parameters to determine whether the
-message is a message of type @var{type}.
+message is a message of type @var{type}. The function will be called in
+the buffer where the message is.
@item function
A function to be called if @var{predicate} returns non-@code{nil}.

+The @code{message-news-p} function returns non-@code{nil} if the message
+looks like news, and the @code{message-send-via-news} function sends the
+message according to the @code{message-send-news-function} variable
+(@pxref{News Variables}). The @code{message-mail-p} function returns
+non-@code{nil} if the message looks like mail, and the

+All the elements in this alist will be tried in order, so a message
+containing both a valid @samp{Newsgroups} header and a valid @samp{To}
+header, for example, will be sent as news, and then as mail.
