Maybe this help (But this looks like a pf question). I'm using postfix 2.1.4. 
It supports virtual domains.
create inside main.cf:
virtual_transport = lmtp:unix:/var/imap/socket/lmtp
virtual_mailbox_domains = beispiel.test sample.check
virtual_mailbox_maps = hash:/etc/postfix/virtual
virtual_alias_maps = hash:/etc/postfix/virtual_alias

Inside 'virtual_mailbox_maps' u write f.e.:
@beispiel.test    egal
@sample.check     equal

Inside 'virtual_alias':
mama at beispiel.test   papa at beispiel.test
mum at sample.check     dad at sample.check

With cyradm u'v 2 create:
user.papa at beispiel.test
user.dad at sample.test

These are virtual users!
