I have done this at the MTA level itself for a virtual domain setup
service hosting multiple domains and no local accounts. I explicitly
list the users for whom i want to accept the mails for rest I reject
blah at foo.com OK
that accepts mails only for foo.com and rejects others. Then the MTA
queues the mails. MailScanner processes it and requeues, MTA then relays
it to other Mailserver where the actual mailbox is located.
