I have a VPS with the following IP: 184.108.40.206
domain: example.com hostname: server.example.com PTR record: 220.127.116.11 > server.example.com
There is no an "A" record for "server"
mood@desk:~$ host 18.104.22.168 22.214.171.124.in-addr.arpa domain name pointer **server.example.com** mood@desk:~$ host **example.com** example.com has address 126.96.36.199 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 188.8.131.52 > example.com?
Is this a good RDNS record or not?
If not, what is the correct RDNS (PTR) record for a mail server?
