How to Configure Multiple Mail Domains with a Single PTR on aaPanel?

Kaarlela

I have a virtual server with a single IP address, and the domains are set up as virtual hosts. Only one PTR is available, and I would like one domain to act as the 'mail domain,' with the PTR pointing to this domain. Other 'mail domains' would then be routed through this one.

However, I cannot create a 'mail domain' with an 'incorrect A record.' For example, if the domain is mydomain.com, I cannot set its A record to point to mail.mymaildomain.com (which has a valid PTR).

I need a solution that allows me to host multiple email addresses, such as info@mydomain.com, info@mydomain2.com, etc.

What can I do?"

Hello, the PTR record is generally an IP corresponding to a domain name. You can go to the provider to see if you can add multiple records?

Hello

I have 5 domains at this moment with single ip. Just install Linux Tools 2.3 on your server from app sotre.

On Linux Tools select hosts, add host, set ip and (example) mail.myhost.com.

Then recheck PTR on Mail Server.

Regrds.

This should just give him a green checkmark, but it will not reduce any spam scores. Because now the PTR is just resolved internally if it is resolved through the hosts file.
I am also struggling with a solution to correctly set PTRs for all domains on the server. Because contabo is only allowing one ipv4 ptr.
