An interesting cost benefit analysis of this would be to take the amount
of bandwidth increase if people used encrypted/authenticated pipes as
upposed to unencrypted/enauthenticated pipes just for mail (in this
case) and compare that to the bandwidth lost in SPAM (only count spam
that would be blocked by said authentication system) and see which comes
out larger.
If the bandwidth consumption is less for the encryption, then you have
your answer.

p.s. I'm not sure where to start to get valid numbers on this. Every
scenario I've been able to think of in the time it took to write this
e-mail has major methodological flaws.
