The simpler alternative, which I'm sure paradise offer, is to use a web based email solution which, in effect, puts you back into their domain for both sending and receiving mail, and the problem goes away. Lets be honest, there aren't many of us sad people who carry a computer that would require this service, unless their company provided for this eventuality - road warrior vpn or something similar- and you user their corporate servers. Note that I'm trying to be practical, not correct here. The world was a far more niaive place when those rfcs were written, and spam wasn't a problem. Steve
