At the risk of posting a 'me too' email, we have also had issues getting a
similar problem resolved with AOL.  We have been receiving numerous ISP:B2 and
ISP:B3 rejection codes from AOL email servers.  We have contacted their
postmaster # as posted on their website and each time talked with a very nice
support tech.

However, in each and every case, we were not able to get the problem 
resolved. AOL even went so far as to say that they would escalate and 
have a member of
their tech support team contact me which never happened.

We have subscribed to their FBL service for over a year.  Lately, the messages
that we receive in the FBL are nowhere near spam.  We contacted the
complaintant @ AOL and each time they responded that they hit 'report as spam'
instead of delete which is right next to each other.

If someone from AOL is reading this, please forward to someone in your
postmaster team.  All other means to contact AOL Postmaster have resulted in
