Well I am very happy to say that my email problems appears to have been fixed, it was the number of instances in /etc/xinetd.conf that was causing the connection problems.
I am extremely thankful to "toml" for his help and to "rszkutak" for all of his help as well. Not only is the connection problem taken care of but the duplicate email problem appears to be fixed as well.
I also want to drop a big thank you to John at DirectAdmin who went out of his way to help me as well. He mentioned in his last email that he has changed the install procedure for DirectAdmin to check xinetd.conf for 60 instances and up it to 256 during the install automatically so hopefully some grief will be saved for new CentOS users.
