Good day.

I have a simple question that I am sure you can help me with.

Our DNS table states that any queries for europe delegate to their
nameserver as stated below

europe IN NS
IN NS IN A 190.x.x.x IN A 200.x.x.x

Want we want to do is to add an MX entry for eruope domain to point to
our mail gateways in our DNS table

europe 300 IN MX 0
300 IN MX 5

Will this work? or will the delegate setting above take priority over
this MX record Which then means that they will need to put this record
on their DNS table
