Intro & an Email Question

Hello hello!
My name is Zeb & I'm a 24 year old female living in Auckland, New Zealand. Was gifted a Nokia 7650 and am absolutely loving it (of course!)

I've got most things sorted re: useing it, but one thing I haven't been able to work out is HOW to get the phone to download email from specific people?
I've got it configured to check one of my domain accounts but I receive a large volume of email and only a few of them I want to read from my cellphone.

Any tips? Instructions? On how I can get the phone to download email from specific email addresses?

Mucho appreciated :)
