I've been trying to figure this out and no luck... I still think that 
one possibility could be a Sieve script that would discard messages 
based on a message-ID cache like the procmail recipe does. Does 
dovecot's deliver have some sort of message-ID cache that could be used 
to removed the duplicates? Or if anyone has any ideas how to do this, 
I'm open to suggestions =)
