Like google has for setting up GMail with POP on OE and Outlook 2003?
Their tutorial is very good and explains forwarding, etc.
mail.yourdomain.com .. dont really have to change any other settings, can be either pop or imap
Is this the kind of tutorial you were looking for:
Configuring Outlook Express - H-Sphere User Menu Based Guide - Positive Software Corporation
Ya - looks pretty trivial.
I wrote my own GMail/Outlook/OE tutorial at www.moveonhotmail.com
It was more complicated getting Yahoo mail to work on the client.
