No guarantee how long it will last, but I did verify that that will not 
block any ports before signing up as I was coming from Business Class 
with Time Warner/Spectrum.

Anyway, AT&T came through. I posted on their forum and got a response 
from someone at AT&T. They gave me the contact information for their DNS 
services. This morning they updated the PTR record and mail is working 
for sites that it wasn't working from before.

Thanks for all the help everyone.
