ATT.net private blacklist

[Ben Browning <benb () theriver com>]

Greetings,

We have somehow fallen into the private blackhole list maintained by 
att.net at blacklist.mail.ops.worldnet.att.net

I have tried for the last two days to approach ATT via phone and email with 
no response whatsoever. abuse () att net, abuse_rbl () att net, and several 
addresses pulled from ARIN and NetSol lookups have not yielded any 
response. The calls I have placed have resulted in me leaving a message 
that was never returned and several instances of "Try abuse_rbl () att net". 
None of these are working at all. On top of that, there is no page or FAQ 
pertaining to blacklist.mail.ops.worldnet.att.net
 (at least, not one that is readily apparent to myself or Google).

If there are any ATT.net admins here, or someone that may have some contact 
information of said admins, I would appreciate an email or a call.

Thanks!

~Ben
