There's a paradox here. Authentication etc costs money, even if just
microcents it adds up in some contexts. People want e-mail to be
essentially free.
I think we can probably find ways to prevent people from bringing fork
lifts into the all you can eat buffet. But fraud and authentication in
general is a huge topic which probably is best solved by someone
figuring out a model for a "charging for authentication business",
akin to registered or certified mail.
Put another way, it's one of those problems that seems to be easy on a
very small scale (exchange PGP keys with your friends), but becomes
very hard as you scale it up, particularly if the first criteria is
that it must not cost anything.
