My SBS 2003 server was earlier running on XO communications which I now switched to Time Warner. Hence I needed to setup my email server once again. After doing the same many of my sent mails are not getting delivered and are coming back to me. I guessed the problem would be due to PTR hence I called up Time Warner and requested them to install a PTR for myserver.mydomain.com point to our static public IP. But in response they said they dont do PTR records or reverse lookup zones.
So I wanted to know from you guys what can I do now to fix the issue. Can I just add these records to my DNS server? Please provide some help.
