bjan.freeshell.org doesn't resolve, so I am posting here.

I think you've described http://cr.yp.to/im2000.html
I think I saw a mention of BMTP on that list too. Also Bernstein
suggests ISPs become banks, so that receivers can charge unknown
senders money. I think this is what will eventually happen (in the
bazillion years that it will take) to the Internet in order to
finally solve spam and forgery issues. The key point is with filtering
it's still more expensive for end-users and admins in time and effort
and bandwidth than for a spammer to send. They just increase the flood
as the result, and we end up paying for the increase in time and
hardware/bandwidth. Filtering is NOT a "solution."

but by learning to see an imperfect person perfectly.
