    I have a CentOS VPS server running WHM/cPanel. Lately, I haven't been receiving email notifications from my forum hosted on this server. Long story short, I looked at exim log and seen every notification going to me had the following error:

    The problem is my host name wasn't set as a fully qualified domain name. Simply changing the host name to instead of mixmaster fixed the issue.

    Hope it helps anyone who has come across the same issue.
