I need some help with Reverse DNS as I have got a problem with it. I have setup rDNS on my hosting provider which I use rdns1.example.com and I have a server hostname which it is gateway1.example.com. I want to use both different name to get it separate because of the email providers that want to see both different names so my email would go to inbox.
When I open on the Email Deliverability software through in the cpanel, I can see this:
Can you please advice me with what I need to do?
How I can match with the rDNS?
Do I need to change the server hostname to match with the rDNS or what?
I want to use smtp513.example.com to send the email and I want to use gateway1.example.com to get access to whm and cpanel. I am not sure what I need to do so I need your help with this.
