How to configure Reverse DNS, PTR and MX records for private email server behind Comcast Static IP
Hello, I have some questions on how to set-up Reverse DNS, PTR and MX records for our private Exchange email server sitting behind a Comcast Static IP address.
We run our own Exchange server on a private network behind static IP address: 188.8.131.52. Our domain is www.estarmail.com and mail.estarmail.com for email. I have registered these domains and set up Reverse DNS, PTR and MX records at REGISTER.COM our registrar.
When I go to DNSQUERY.COM I get no results for A, CNAME, MX and TXT queries. The DNS and PTR query properly return estarmail.com for my IP. The reverse DNS query returns an undefined (???) PTR to my domain. The WHOIS query returns Comcast Business Communications, LLC.
What can I do to get the various missing or incorrect DNS records set up so they will resolve properly to our static IP and domain?
