What makes you think jm> that their mail credentials will be hard to obtain? Internal users: With AUTH - correlate message with authenticated user, then forbid mail transmission for them only. I'd rather do that than slog through RADIUS logs. But, hey, maybe if I had more free time... External users: They must send mail somehow. If saying "You roam? Use this port!" is too difficult, try explaining multiple profiles. Short of using 25/TCP on the service provider's network (which could be amusing for those using wholesale dialup providers), users need some way to pass email.
