The spam traffic is making its way to AOL, and AOL has added your mail server's IP address to an internally maintained AOL IP blacklist. What most sites, including AOL, want to see for a PTR is a host name that matches the DNS for the server - so mail.example.com. If there are other accounts from your mail server that are sending spam, AOL may block the IP because of that traffic and not because of your account alone. Another report I've seen is that email addresses with "a" "o" "l" in order (like, for instance, [email protected]) are also getting rejections.
