Based on the above ps output, your running sendmail, not postfix. Sendmail, by default, is configured to only listen on localhost. If your wanting to use postfix as your MTA, then please run "redhat-switch-mail" to configure the proper links in /etc/alternatives.
I had already done the switch and rebooted but sendmail was running again. I am going to look into doing the switch manually this time to confirm. I also had already editied main.cf to listen to all devices as a test and that did not help.
Thank you for the help, I will go play some more
