Hi, I installed, using the perfect settings for Fedora Core 4. Mail accounts can send mail, but no reception is allowed. Bounce message is "Diagnostic-Code: X-Postfix; mail for srv14.lab-project.net loops back to myself" Reading around about this problem, I cannot figure what goes wrong. Checking postcong -n sounds correct, as well as local-host-names and all other ways described in other posts. I guess I made something wrong somewhere, but cannot find what.
