Variables for customizing outgoing mail:
gnus-uu-digest-headersnil include all headers.gnus-add-to-listnil, add a to-list group
parameter to mail groups that have none when you do a
a.gnus-confirm-mail-reply-to-newsnil, 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-newsnil, 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.
