rDNS/PTR record check failed.

Hi,
I am facing a weird problem. In my cwp i configured all things. I parked 7 domains and they are working well. But when I run "Check Records" from DNS Functions for my main domain xeronce.com, i got error. (dns1.registrar-servers.com. & dns2.registrar-servers.com.) is not my nameserver, this is namecheaps name server, I already changed my nameserver to namecheap.


Interesting thing is, my server ip is : 144.217.81.246 but i don't know, 192.64.119.189 ip come from where... 192.64.119.189 this is not my ip...

and my other domain "Check Records" return this result:




please help me, my clients can't configure email server for my dns problem. Coz, xeronce.com is my nameserver domain.
