POP server that supports virtual users/domains (other than dovecot)?

[Philip Hallstrom]

Hi all -
 	Looking for recommendations for a POP server that supportts 
virtual users and domains and preferably hooks into PostgreSQL.  dovecot 
does this and I'm looking at it now, but it's got a lot of IMAP stuff that 
I will never ever use (really I won't).

Anyone have recommendations for other packages?  I've searched, but would 
like some actual user experiences...

Thanks!
