Thanks very much for the reply. I think my root difficulty was understanding the hierarchy behind forwarding rules (in this specific case; between relay and transport related parameters / tables). Your examples put me onto http://www.postfix.org/transport.5.html which gave me a much better idea of the order of precedence and which parameters win out over which in the event of a conflict.
Thanks again, Scott ________________________________ From: owner-postfix-us...@postfix.org <owner-postfix-us...@postfix.org> on behalf of Wietse Venema <wie...@porcupine.org> Sent: May 28, 2020 11:53 AM To: Postfix users <postfix-users@postfix.org> Subject: Re: Relationship between relay and transport Scott A.

This would - Deliver example.com to the inside host. - Deliver other domains to the inside host. So they do different things for other domains. Wietse
