IMGate can't do anything about write-only rigidities of MS params, but postfix can re-write all addresses in, out, or both, so whatever domains are used on the exchange box can be totally hidden from internet. man 5 canonical We used this when one of our exchange clients, behind our IMGate, got bought and had a company name + domain change. We were able to use canonical_recipient_maps so incoming mail got re-written: @old.domain @new.domain Len
