Re: Abandon SMTP
"Set the wayback machine to the 1980s and see how X.400 looks as a concept. An email setup designed from the ground up to support authentication, anti-tamper, encryption, and so on. Even been proven to work, on battlefields and the like."
Also as I recall proven to be a right mess. It's just plain too complex, as anyone who's had to untangle a misdelivered X.400 message can attest. You need a secure solution, yes, but it has to be a SIMPLE secure solution. Otherwise, you run into the wrong end of the secure-vs.-easy to use scale. In order for something to actually be practical, it has to be in the MIDDLE of the scale: BOTH secure AND easy to use--otherwise people either end-run around the encryption or it'll be full of holes.
