Hello, I have a client that is running their mail server from my network. The domain that they are using is hosted on another network down in Miami, which is far far away from where I am at. I am using windows 2000 for my net’s dns. They are getting mail kicked back due to RDNS errors. So I made a reverse entry for the mail server’s IP but I do not know what to point it too. So I made a forward zone and called it mail.example.com; then I created an A record and pointed it to the remote IP. But I am getting
*ERROR* A record does not point back to original IP.
What do I need to do to correct this?
