A summary of the problem. ------------------------- Hello, I am new to the list but a long time Postfix user. I have am trying to accomplish the following, but am unsure of how to exactly go about doing it. I need to re-direct a few specific recipient addresses to a host other than the relay host I have Postfix send to (that relay host for our domain that Postfix delivers to being Exchange Server.)
My environment: For inbound mail: MX record points to Postfix server. That Postfix server relays mail for domain.com to Exchange Server 2003. For outbound mail: Exchange Server 2003 relays all mail destined for outside through Postfix. I need to map inbound mail destined to specific recipient(s) or sub-domain(s) to onto a different host and not onto Exchange. For example: Inbound mail for j...@domain.com => MX lookup => Postfix => Exchange OR Inbound mail for domain.com => MX lookup -> Postfix => Exchange IF Inbound mail for supp...@domain.com => MX Lookup => Postfix => Support Server running Postfix MTA to receive OR IF Inbound mail for support.domian.com => MX Lookup => Postfix => Support Server running Postfix MTA to receive I am thinking that if I was to use Postmap commands to alter the transport, something like: Support.example.com smtp:support.local That may allow me to redirect mail for subdomains to another host, however I am uncertain. I am uncertain how to redirect mail for specific intended recipients. Thank you very much in advance!
