	I have one idea (may be stupid :-)) ) -- we use Cyrus POP/IMAP server
   and patched cf/crossbar.cf.  When crossbar() function rewrite recipient's
   address it looks in my special database (like aliases but we use as key 
   user part of address and cyrus-mailbox name as value).  So, we can use
   several files for every virtual domain.

	What do you think about this?

P.S.  One disadvantage of this idea is that we can't have user1@domain1 and
      user1@domain2 address without POP/IMAP server patches.
