Pertaining to the same discussion. Can someone validate below zone files
and named.conf files? What I wanted to achieve here is; I wanted to make
mail.example.com as my sub domain and give them A record so that I could
load balance the traffic on LBs since my LBs are offering inbuilt DNS server

You also need:
IN NS ns1.example.com.
to be more precise it's not needed, but recommended, since
- it's recommended to have more NS records
- the delegation NS appears in parent zone
- NS records from the zone prevail over delegation and if
ns3.mail.example.com fails and resolving DNS has authoritative NS cached,
it won't query ns1.example.com. until the authoritative NS expires.
