I have issues emailing to certain domains. I use my own mail

I'm amazed that it works at all. Like most ISPs, AT&T usually blocks
port 25 on their consumer broadband.
If you want to run your own mail server, get a VPS somewhere. They're cheap,
like $5/mo or less if you pay by the year. If you just want your mail to work,
get it hosted somewhere.

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.
