Their server bounces his messages with this error:
550 5.7.1 Connections not accepted from servers without a valid sender
domain.flph840 Fix reverse DNS for 66.171.0.45
But I sent a test message to his intended recipient and my test
message was received.
Our DNS has been "as is" for a very long time and we're not getting
any rDNS errors from any others.
They may be having a problem with the existence of 2 PTR records. It's
not formally wrong, but it's a good way to generate odd problems with
people who try to validate your DNS.

Please email me directly if you have insight to that domain and
can assist.
That's AT&T. And what is the "odd response"?
