rDNS doesn't point to the correct subdomains

I have 2 domain names. I tried to create the subdomain for domain2.com like this:


I created the DNS zone with that subdomain and ip. However, when i checked it, that ip was reversed to mta12.domain1.com instead of mta12.domain2.com.

I checked the losf with pid of named, i found these:

Hello :)

Have you verified with your data center that your server has control over RDNS records? If so, ensure you follow the steps listed in this document:

How to Configure Reverse DNS for BIND in WHM - cPanel Knowledge Base - cPanel Documentation

Thank you.
I think i do. This is dedicated server.

Here is my reversed conf

I have a dedicated server, but as Michael has said, the RDNS records are controlled by the DC and not me.
I emailed my server providers, who applied the change at the DC.
