First, thanks, all, for the quick replies with
regards to the AOL email situation. The update I got from my client's
email provider is that they have been blacklisted by AOL (reason not given), and
have asked for our assistance in solving the blacklist problem.
You **really** have to look at the log on the mail
server. It is made very clear in AOL's bounces how to go about getting
more information on the block.
