Subdomain MX

[Terpasaur]

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       server01.europe.school.edu.
                         IN      NS       server02.europe.school.edu.
server01.europe.school.edu.        IN      A         190.x.x.x
server02.europe.school.edu.        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       smtp01.school.edu.
            300     IN      MX      5       smtp02.school.edu.

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
