I, too, use RoadRunner for my POP3 connection (socal.rr.com) and have found that they prevent users from using their outbound server (smtp-server.socal.rr.com) with wireless devices (i.e PPCs). It has something to do with spam prevention. What I ended up doing was using my wireless provider's (VZW) outbound server. Took me a couple of days to figure that one out. Give that a try and see if that helps.
