Default Setting up reverse DNS on an ISPConfig 3 server


I want to make sure I set up reverse DNS correctly for my domain/ip and DNS.

Since it is not correct now, I get warning messages and ultimately I am afraid that my server may be recjected or blackballed from email providers that perform reverse DNS lookups.


When I open an ssh session, I get:
reverse mapping checking getaddrinfo for [] failed - POSSIBLE BREAK-IN ATTEMPT!
I am in control of my own DNS zones and records for my domains.
