5.4 Mail and Post

Here's a list of variables relevant to both mailing and posting:

gnus-mailing-list-groups

If your news server offers groups that are really mailing lists gatewayed to the NNTP server, you can read those groups without problems, but you can't post/followup to them without some difficulty. One solution is to add a to-address to the group parameters (see Group Parameters). An easier thing to do is set the gnus-mailing-list-groups to a regexp that matches the groups that really are mailing lists. Then, at least, followups to the mailing lists will work most of the time. Posting to these groups (a) is still a pain, though.

gnus-user-agent

This variable controls which information should be exposed in the User-Agent header. It can be a list of symbols or a string. Valid symbols are gnus (show Gnus version) and emacs (show Emacs version). In addition to the Emacs version, you can add codename (show (S)XEmacs codename) or either config (show system configuration) or type (show system type). If you set it to a string, be sure to use a valid format, see RFC 2616.

You may want to do spell-checking on messages that you send out. Or, if you don't want to spell-check by hand, you could add automatic spell-checking via the ispell package:

     (add-hook 'message-send-hook 'ispell-message)

If you want to change the ispell dictionary based on what group you're in, you could say something like the following:

     (add-hook 'gnus-select-group-hook
               (lambda ()
                 (cond
                  ((string-match
                    "^de\\." (gnus-group-real-name gnus-newsgroup-name))
                   (ispell-change-dictionary "deutsch"))
                  (t
                   (ispell-change-dictionary "english")))))

Modify to suit your needs.

If gnus-message-highlight-citation is t, different levels of citations are highlighted like in Gnus article buffers also in message mode buffers.
