I am getting a bounce back mails with error code, "Forged hostname for XX.XX.XX.XX which resolves as srv30.vorexa.us but srv30.vorexa.us does not resolve back to XX.XX.XX.XX. Check your DNS A and PTR records. "
I found some help on line, which was this advise.
..The issue is with your Reverse DNS / Pointer Record (PTR). You will need to contact your ISP (Internet Service Provider) and request that they configure a valid PTR that resolves to the proper IP address.
We recommend having mail.xxxxx.com configured as the RDNS for XX.XX.XX.XX.
I contacted my ISP, who is LightPath, but they have no idea what I am talking about. Please help. Thank you.
