The best thing to do in this type of situation is to make sure that your mail server has logging turned on. Afterwards, try sending a test message to an AOL account. In your log files, search for the message. The AOL mail server will usually return a link with the error message. The link will provide information from the AOL.com site as to why the message was blocked.
Often times, AOL will not accept email from a server unless that server has a reverse DNS entry in place. To have a reverse DNS setup you will need to contact your ISP and have them create a PTR record to point back to the A record of your mail server. This link has a test to see if your mail server’s reverse DNS is setup: http://www.dnsstuff.com/
In the reverse DNS box enter the IP of your mail server. If a reverse DNS is in place it will be displayed.
