Put a VPN client on the roamer's computer (Linux, Mac, and Windows 9x/NT/ME/2k all have IPSEC capable clients available), then use the VPN to get back to the mail relay. If the mail relay is behind the VPN tunnel termination point at the server end, then it should only accept mail for relay from valid VPN clients. As such, you solve the roaming staff problem without an open relay. VPN boxes like Ravlin and Nokia Crypto Cluster are cheap enough today that I would consider it a valid cost of doing business if you don't have a better solution. Owen
