- ;; and someone mails a message with 'To: foo-bar@gnus.org' and
- ;; 'CC: foo-baz@gnus.org', we'll pick 'mail.foo.baz' as the group
- ;; if the cc line is a later header, even though the other choice
- ;; is probably better. Also, this routine won't do a crosspost
- ;; when there are two different matches.
- ;; I guess you could just make this more determined, and it could
- ;; look for still more matches prior to this one, and recurse
- ;; on each of the multiple matches hit. Of course, then you'd
- ;; want to make sure that nnmail-article-group or nnmail-split-fancy
- ;; removed duplicates, since there might be more of those.
- ;; I guess we could also remove duplicates in the & split case, since
- ;; that's the only thing that can introduce them.
