Greetings Brain Trust,
We have found ATT to be heavy handed with their email (spam) filtering. Without warn all of our mail servers
will be denied from delivering email to their many domains (att.net, bellsouth.net, etc). They have a removal
request form (like most other large ISPs) which takes 2 days to process. We never find out why the we get
listed. We always check as many "email" reputation systems and rbl searches to determine why. Everywhere we
look we see no evidence of a problem. We have joined other ISP feedback look system, (AOL, Yahoo and even
Hotmail/Live) which all have helped stop issues (comprised accounts, bots, etc) before they get to the point
of a listing/block.
I have searched and I can not find out definitively whether ATT has or does not has a feedback loop system.
Anyone out there know?
