DNS Question changing MX record

[#1]

Will plus net allow me to change my MX record?
I currently don't have a domain set up so cant see.
The reason i would like to do this is so i can setup gmail in google apps with our domain.

Andrew,
Are you saying that you have a domain but it isn't with us?

Yes, its with 123reg, however,
I haven't yet set it up with plus nets name servers, so cant see the DNS options that would be available.
I  was wondering if it could be possible to change MX settings once the domain had been set-up with plus net
UPDATE: should add that i will be using plus nets webhosting aswell

You can use whatever you want as your mx records.
