How to set up 2 mail domains on 1 Kerio IP?

Question

Domain Name System

There is a Kerio connetct mail server and 2 mail domains test.com and test.net.
They must live on the same server and, accordingly, the same IP.
At the same time, I cannot register 2 ptr-records for 1 address.
How can this situation be resolved?

Answer 1

ptr entry must exist. Nobody ever required it to point to your domain.
the domain pointed to by the ptr record must point to the same ip. This is a prerequisite.
