Subject:	problem with 'loops back to myself'
Group:	Postfix-users
From:	Christopher Adams

I am having this problem after simply changing the name and IP of a
server running Postfix.

As per the answer below, I have this in the postfix main.cf file:

mydestination = $myhostname, localhost.$mydomain,
localhost.localdomain, address1.$mydomain, address2.$mydomain

address1 is name of the server and address2 is an alias. Messages sent
to address2 result in the error message.

34. I can't seem to receive messages. What does this error mean:
"<test>: mail for example.com loops back to myself"?

Postfix reports this error when a DNS reply points to your mail
server, but Postfix hasn't been configured to deal with messages
addressed to the domain. Postfix accepts mail for domains listed in
mydestination, relay_domains, virtual_mailbox_domains,
virtual_alias_domains, and domains that resolve to IP addresses listed
in inet_interfaces and proxy_interfaces. The domain must be listed in
one of these parameters
