ATT.net postmaster contact

Howdy,

Does anyone know of a good/working ATT.net postmaster contact? We have been trying for several weeks to get an IP that has never been used before removed from the ATT.net blacklist and we aren't getting replies through the forms on their site.

Thanks,
-Drew

I've had good luck emailing them at abuse_rbl@abuse-att.net. Takes a
couple days to hear back from them, but they do generally reply.
