If we tried to follow his suggestion and made the user supply an SMTP
server, chances are about zero that we could actually _use_ that SMTP
server to send mail on the user's behalf.
IMP demo site -> connects to user's local SMTP server -> tries to send mail
to someone not at that ISP -> Whoops! Relaying denied.
It's just not feasible for the vast majority of cases.
