I dislike, that the re-delivered messages get at the end of the list (so first new message). I don't know why I didn't think of it before. I use imapfilter for other things (archiving... maillist management...). And it supports a pipe_to(). So I did the following config: results = mailbox["LearnAsSpam"]:select_all() for _, mesg in ipairs(results) do mbox, uid = table.unpack(mesg) text = mbox[uid]:fetch_message() if (pipe_to('/usr/bin/sudo -u vscan /usr/bin/sa-learn --spam --single 1>&2', text) == 0) then spamlist = Set {} table.insert(spamlist, mesg) spamlist:move_messages(mailbox.spam) end end results = mailbox["LearnAsHam"]:select_all() for _, mesg in ipairs(results) do mbox, uid = table.unpack(mesg) text = mbox[uid]:fetch_message() if (pipe_to('/usr/bin/sudo -u vscan /usr/bin/sa-learn --ham --single 1>&2', text) == 0) then spamlist = Set {} table.insert(spamlist, mesg) spamlist:move_messages(mailbox.spam) end end I just miss the part, that the mail doesn't get processed by spamc again. but I can send the mail to sa-learn and then move the message (instead of re-deliver). happy now. _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
