Roving Profiles in Exchange

I have roving profiles working in exchange. The only problem I am having is that I need to configure Internet email within the profiles. I have not found a way to do this in any software. I have tried scriptlogic pro and also made a batch file usingthe profgen and other utilites. I also tried the profile designer utility from slipstick.com. Does anyone know how to this. I'm gonna get all internet email forwared to the exchange server sometime I just have to get this working until then.
