Philip Prindeville <philipp_s...@redfish-solutions.com>
is rumored to have said:
We're being blacklisted by att.net with the following message:
(reason: 550 5.7.1 Connections not accepted from servers without a
valid sender domain.flph840 Fix reverse DNS for 24.116.100.90)
I don't know what the hell is up with these pinheads:

So that's not the problem. You're supposed to be able to get the
blacklisting fixed if you email abuse_...@abuse-att.net
<mailto:abuse_...@abuse-att.net> but I've emailed them from 3
different addresses and have yet to get a response much less a
resolution.
Has anyone else had to deal with this bullocks and gotten it resolved?
Yes. Twice.
Time is your friend. AT&T still operates like it's 1970...
