I use Gnus in emacs as my mail service. Because I have several computers and many email addresses, I use an extra address to store my sent messages. Since I use gnus on several computers during the day, I want to sync my sent mail and to do so by pop3 downloading my sent mail to my archives.sent folder; so far, no problem. But now I want to make sure all those downloaded messages, while available in my sent folder, are not marked as unread; they should not call that attention to themselves.
Is there a simple way to use split mail (or something else) to mark them as read as soon as they are sorted? It would be a pain to have to use catch-up on them every time.
