Are you sure this is BellSouth's doing?
I ran into an issue a couple of years ago with the Elecraft list,
which is run out of qth.net. Even though I am subscribed to the list,
my postings were rejected out of hand, with no warning.
The problem had to do with a blacklisting service that qth.net was
using. The blacklisting service set up a honeypot computer and then
proceeded to blacklist the IP address of every mail server that
carried spam.
While the blacklisting service was intended to block spammers, it
unfortunately took a lot of innocent folks with it -- particularly
from large ISPs such as BellSouth.
What basically happens is that someone has a 'bot computer on
BellSouth.net that the spammer uses to send e-mail. This spam gets
caught by the honeypot, and one of the BellSouth mail server IPs gets
blacklisted. The poor customer doesn't know their computer is being
remotely controlled, and thousands of innocent users of BellSouth.net
find their e-mails blacklisted.
I hate spam as much as the next guy, but these techniques that harm
innocent users really piss me off.
