I recently had issues with ATT (and SBC and Bellsouth). It also involved a
fairly newish IP range we were warming up and when we moved the bulk of the
traffic over things came down like a hammer. I would get the block lifted
and within a few days it'd start all over. I reached out to the ATT
postmaster and they informed me it was a "volume/time threshold" and from
there we were able to get things resolved.
