I added the following entry (Plesk -> Domain settings -> DNS Settings):
12.345.678.912 / 24 PTR mail.domain.com
The IP address matches the mail.domain.com IP address as that is the one which sends out emails.
I checked the PTR here and the checker says that there is no PTR record. I tried with mail.domain.com
How to setup the PTR records correctly from Plesk? Any clues how to settle this down?
Thanks a lot!
Who hosts your plesk server?
Usually your hosting provider who gave you the IP address will run reverse DNS for their IP addresses and will need to add the reverse entry to their system. You do not add PTR records to the zone file for your domain.
It's possible you have been given a range and they have delegated control of this range to your own DNS servers, but probably not. Either way the admins who assigned you the IP should be able to help.
