AOL does require that all connecting Mail Transfer Agents have established reverse DNS, regardless of whether it matches the domain.

This means if your mail server doesnt have a Reverse DNS record, your messages sent to AOL will fail.

Go there:  http://postmaster.aol.com/tools/rdns.html
and you'll be able to test your server IP and see that it can't find your Reverse DNS information.

So your solution is to update your DNS Server to include a Reverse DNS record.

I'm getting different solutions on this issue, one is pointing to the Reverse DNS Lookup, which I'm still looking into this, the other pointing to the #4.4.7. code which indicates there is a problem with the recipient's end and not our end.  I'm leaning more towards the DNS isssue because this is what i get when checking the DNS Evenviewer on the the Domain controler Server:
____ The DNS server has encountered a critical error from the Active Directory. Check that the Active Directory is functioning properly. The extended error debug information (which may be empty) is "". The event data contains the error.______Event ID: 4015.

Your reverse DNS is most likely handled by your ISP, not in your own Active Directory, but you should fix your AD DNS anyway.

Perhaps you should give them (your ISP) a call and see what they say about your reverse DNS.
