I’m looking into setting up Postfix or something similar. Can one instance of Postfix serve two domains? Is there any reason not to do that? Also, I’m interested in feedback on Postfix and any alternatives. Thanks.

Hello, @jonsidener
Yes, you can configure Postfix to use more than one domain name.
You can follow our tutorial on How To Configure a Mail Server Using Postfix, Dovecot, MySQL, and SpamAssassin

As a side note, here is an interesting read on why you may not want to run your own mail server but rather use an SMTP provider:

Hope that this helps! Regards, Alex
