Thanks to a friend very familiar with Debian I have my first Debian server up and running on a Dual Processor IBM Netfinity Server. One word: ROCKS!
Just in playing around I see what I was hoping for with RH, speed, stability, performance! NICE :)
Moving user accounts over tonight and will start the tests for it to become a replacement email server.
Thank you to everyone on the list for your help.
