That's an interesting idea. The part about reaching into Dovecot
to move the message is slightly worrying; it implies that the scanning
process has significant privileges. But yes, it could be a really good idea.
An enhancement would be to automatically train messages in Junk as spam
if they've been there for at least 5 days.
