Moreover, in the public policy debate that is going on now, policy
makers
need to know what technical options are avaiable as they look at the
spectrum
of possible solutions (legal, technical, etc). The IETF has a role to
play
there, too.
Absolutely. We need to get something like RFC1984. As bad as spam is, a
lot of the countermeasures have a significant cost. It is probably
necessarily so, as making e-mail easy to send also makes spam easy to
send, but different measures have different side effects, and that is
worth documenting.
