Postfix Fails on Restart

Hey all-- In over my head here. I have a new Moodle installation which gets messages returned from some users, complaining about no PTR record and reverse DNS. My server is openSUSE 11.0, Moodle is 1.9 . Other than that, I have no messaging/mail systems running. I have no domain name, only a fixed IP address.

If I use rcpostfix restart, I come up with “Failed” for the Postfix Start. The only change that I’ve made to is entering my IP address for myhostname = .

Any suggestions? Thanks!

If you want to setup mail server, please apply a domain name and then configure your dns record for A, MX and PTR.
