This is my current setup on an Amazon EC2 system, running CentOS 5.3.

I'm thinking its because my DNS is jacked and I need to install Split DNS, but I am uncertain. Any help would be greatly appreciated. Thanks!

The usual reason for this error is a DNS problem and if you're behind a NAT router (or firewall) you'll need a Split DNS. The hosts file is also incorrect, it should only contain the following:

127.0.0.1       localhost.localdomain   localhost
174.129.4.202   mail.domain.net        mail
