We setup dovecot on our outbound relay to talk to a database containing the user information and provide the auth socket to postfix. Unless the address of the recipient has the same domain as the local postfix instance all messages will be relayed on (we set the local domain to something bogus like domain.internal so no mail is attempted to be saved locally).
