Setting up email via a win 2000 server, using osx jaguar.

Hi, I've used macs for a few years, but have recently joined a company who have never had any, now i have my machine and we want to hook it up to a win2000 server.... I have absolutely no idea how to do this and to gain access to the internet and what to use for email. (always had a tech to do it before now)
Anybody help? please
