Seems like AT&T *ARE* doing the correct thing and it is *YOU* with the
problem. before you start calling others f'wits do better investigation,
a dig trace indicates root servers dont know you.

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?
Thanks
