I have a VPS with the following IP: 82.197.45.124
domain: example.com
hostname: server.example.com
PTR record: 82.197.45.124 > server.example.com
There is no an "A" record for "server"
mood@desk:~$ host 82.197.45.124
124.45.197.82.in-addr.arpa domain name pointer **server.example.com**
mood@desk:~$ host **example.com**
example.com has address 82.197.45.124
example.com mail is handled by 10 mail.example.com.
They say that DNS lookup must match reverse DNS lookup.
But as you can see there are no exact match; server.example.com != example.com
Must I change the PTR record like 82.197.45.124 > example.com?
Is this a good RDNS record or not?
If not, what is the correct RDNS (PTR) record for a mail server?
