Sorry but I want to understand this clearly. The MX record for
mail.example.com is pointing to the Postfix server which then relays to an
internal Exchange Server. I do not understand what you mena by higher
priority MX in this case unless you mean the mail destined for
mail.example.com. Please slarify.

I do not have a relay_recipient_maps set up (yet) at the request of the
Exchange Admin. He wants Exchange to handle it so that he can have only one
place to look for log messages about what is happening with mail. He says
Exchange handles invalid recipients just fine. Is his logic OK or should
invalid recipient mail be kept from going further than the gateway?
