Its because you have no Reverse DNS zone configured on your public DNS
server for your domain, AOL and a number of other companies perform a
reverse lookup on all incoming mail and if they cannot find a reverse
lookup
zone they reject the message, so you have two options:
1. get someone to configure a reverse DNS zone for your domain
2. Create an SMTP connector with the address space of AOL.COM and have
it
send the mail out via a SmartHost that does have a reverse DNS zone
configured (i.e. your ISP).
