I'm having a problem setting up duplicate filtering on my mail
server. I've set up the mail server with Postfix and Dovecot with
virtual LDAP users, ClamAV virus scanning. The problem is that
some of the virtual users use multiple e-mail addresses and
postfix delivers emails sent to a user as many times as the user
has email address entries in LDAP. I was wondering what would be
the smartest way to get rid of these duplicates, they have
identical message ID:s and a simple procmail recipe does the
trick, however as I'm using dovecots deliver, procmail isn't the
answer.  Is it possible to use Sieve to do this, I've been
googling around *a lot* and haven't found anything that would
solve the problem...

i would assume that there is a postfix mechanism for consolidating these once it has normalized / expanded the rcpts for the message.

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 =)
