there is an unknown domain (changed domain name to domain.com) in Email Deliverability, domain.com does not host or not belong to this server, Even IP address is not belonging to the server

error warning in all cPanel's hosted under this WHM

what could be the issue? Is the server compromised?


The system sends the domain “domain.com” in the SMTP handshake for this domain’s email. “domain.com” resolves to “xx.xx.xx.10”, not “xx.xx.10.10”

To fix this problem, contact your system administrator and request that they create a DNS “A” record for “domain.com” whose value is “xx.xx.10.10”

Hey there! I would recommend checking the Exim log at /var/log/exim_mainlog for that specific message. That would show you the full mail transaction and would hopefully give you more details about where the message was sent from on the server.

We have some additional details on interpreting Exim log data here that you might find helpful for this issue:
