Is there a way to configure Domain Literals?

[abacabb]

When I run a test on my mail server using a tool such as dnsqueries.com....I get the message:

The SMTP server does not accept mails to postmaster@[IP_ADDRESS]. This is a very bad thing, as this address is used by people that don't know your domain name! The reported error is:

501 5.1.3 Bad recipient address syntax




I tried to configure this but Zimbra doesn't seem to allow this...at least with my default configuration. Is there a way to configure this? It seems to be a requirement for mail servers.

See my answer in your other thread. You can't add an email address that contains the IP of your server, it must contain the domain name of your server.
