gnus: Mail

 
 5.1 Mail
 ========
 
 Variables for customizing outgoing mail:
 
 ‘gnus-uu-digest-headers’
      List of regexps to match headers included in digested messages.
      The headers will be included in the sequence they are matched.  If
      ‘nil’ include all headers.
 
 ‘gnus-add-to-list’
      If non-‘nil’, add a ‘to-list’ group parameter to mail groups that
      have none when you do a ‘a’.
 
 ‘gnus-confirm-mail-reply-to-news’
      If non-‘nil’, Gnus will ask you for a confirmation when you are
      about to reply to news articles by mail.  If it is ‘nil’, nothing
      interferes in what you want to do.  This can also be a function
      receiving the group name as the only parameter which should return
      non-‘nil’ if a confirmation is needed, or a regular expression
      matching group names, where confirmation should be asked for.
 
      If you find yourself never wanting to reply to mail, but
      occasionally press ‘R’ anyway, this variable might be for you.
 
 ‘gnus-confirm-treat-mail-like-news’
      If non-‘nil’, Gnus also requests confirmation according to
      ‘gnus-confirm-mail-reply-to-news’ when replying to mail.  This is
      useful for treating mailing lists like newsgroups.
