So I'm trying to figure out how to filter my home mail (attbi) that I pull into PCS BC PE using POP, so that it doesn't show up on my work desktop (Exchange/Outlook). I don't think there's a way to do it. Any ideas?

The goal would be to have my home email pulled into PCS BC, then pushed to my Treo, but stay only on the Sprint server and not sync with Exchange. But there are no filter settings at PCS BC, and I can't see anything in Exchange.
