That will work for senders that don't have a @doamin.com. If you own multiple domains for which you want to receive messages, you may need:
relay_domains = domain1.com domain2.com ... relay_recipient_maps = hash:/etc/postfix/relay_recipients /etc/postfix/relay_recipients @domain1.com x @domain2.com x ... postmap /etc/postfix/relay_recipients postfix reload If you need to deliver the incoming messages to other servers (not local delivery): transport_maps = hash:/etc/postfix/transport /etc/postfix/transport domain1.com smtp:server1.domain1.com domain2.com smtp:server2.domain2.com postmap /etc/postfix/transport postfix reload For all others (relay to external domains - that you don't own) you need to use smtp auth or mynetworks (I prefer first one). Postfix will do the rest.

I am still trying to figure out how this configuration might impact other parts of the service as this machine is supposed to serve a number of domains and a bunch of mailman lists.
