Newbie mail advice

Hi I have setup RT and am at the point of configuring the mail for it using
fetchmail.

I have created an account for user rt on the RT box and added a second
queue.

What mail accounts do I need on the central mail system? rt@gla and
queue2@gla ?

I assume the account doesn’t have to be called rt@gla

If there is a queue@gla mail address how dows fetchmail catch that?

TIA
