Win XP to Linux (Ubuntu 7.04)

Let me say this first, I am not a Microsoft hater. I am just looking to expand my horizons. In that spirit, I have installed and have been using Ubuntu 7.04 on my laptop. It runs great and is very intuitive. Feisty, unlike previous versions, picked up my wireless NIC right away.

Anyway, I like the Evolution email client but have a ton of critical email trapped in a PST. In my own searches, I haven’t been able to find a script or utility that will allow me to import my mail and folder structure into Evolution.

Can anyone offer any suggestions as to how I might be able to perform this migration?
