Major Reverse DNS Problem with emails, e.g. AOL
Posted on 2006-07-13
I host my own mailserver on Windows SBS 2003 Prem / Exchange Server 2003. The domain name for this server is s1.gurkanandgurkan.com, with an IP of 220.127.116.11 and works as our SMTP gateway behind our firewall (DMZ port).
We are having major problems with getting emails to AOL and some other servers. They say the cause is Reverse DNS and wherever I look I find a negative Reverse DNS lookup. Whatever we have tried doing is not solving the problem which is now going on for 6 months. What can ve do to fix it. Please help.
