Hi all,

I need some help with change the domain in the email deliverability. I have changed the PTR from server.mydomain.com to mail.mydomain.com.

In the email deliverability, i can still see the domain "server.mydomain.com" so I want to change it.

Do you know in what file I could configure to change it?

Thank you.

That's obtained by a DNS lookup, it's not something you can change manually. The only way for this to be changed is for the actual PTR record to have been changed and that change propagated.
