Hello,
I have a client that wants to have a dedicated smtp sending host. But they have 2 separate domains then that don't want to have share IP address. The reasons from this is long and drawn out.
Is it possible to setup postfix in a virtual host config, like apache for example, such that, domainA.com listens and sends on one IP address and domainB.com listens and sends on another address.
This host is simply a email forwarding host, so no user accounts are on the server, they have about 5 servers serving websites for 2 domains and subdomains and want email coming from a common source for both domains (this will be the relayhost for the web servers).
I have it setup to listen to 2 ip addresses but as of now I get:
220 smtp.domainA ESMTP Postfix
on both addresses. Is there a way to have one address show as:
220 smtp.domainA ESMTP Postfix
and the other:
220 smtp.domainB ESMTP Postfix
More importantly, email send via 1 should look like it came from that domain and email sent to the other look like it came from its domain.
I can find info on virtual domains, but its geared for receiving email for multiple domains.
Thanks, Rick
