all my emails that i sent to aol all the sudden started to being rejected. i call them i they say it is because AOL will not accept SMTP connections from IP addresses which have no reverse-DNS (PTR record) assigned.
You can check and learn more about your reverse DNS on the AOL Postmaster Web Site: http://postmaster.aol.com/info/rdns.html
Please setup a reverse DNS entry for any IP addresses that are having a delivery issue. Once reverse DNS is setup, the block on those IP addresses should be removed within 48 to 72 hours.
Can somebody help me do this? i am a rookie when it comes to DNS
