Okay so the host file only allows system applications to understand what IP's are bound to a specific host, but in actuality, DNS has to be setup correctly in terms of a public server.
Is my understanding is correct now, then I think I am good to go. Thanks for all your help who responded to this thread Gentlemen.

Reindl,
To my knowledge, all that needs to be configured is A records, MX records, and SPF records (along with correlating PTR's). This is a whole other subject and I feel I will have this correctly configured. My fear is that someone will send email out from my server, and the hostname might come back as my systems host INSTEAD of the mail server hostname.
Is it good measure to add it to the hosts file anyway or is this a waste of time? I guess my understanding of the host file is clouded
the host-file is simply the same as DNS in both directions and does nothing than resolve name/ip locally, normally not needed but maybe a good idea to make sure servers like httpd starts even if no dns is reachable at this moment because httpd refuses to start if he can not resolve his own name
