We have a DNS server on a windows server 2012 R2.
The problem is it doesn’t return PTR, When I do a PTR test at intodns.com or other similar websites they give me this message:
ERROR: No reverse DNS (PTR) entries.
We’ve configured PTR for the domain name in DNS server.
ping -a command return domain address if I’m connected to internal network.
May you help me, This problem is really annoying since our user can’t send email to public mail servers.
