yes, but ask all email users to starts using it, it will take lots
of years to get a significant portion of them to use it. The other
solution is to use pgp to sign the messages at the mta. In any case
none of those solutions could be used before DAT, which does not
solve the problem of bandwith used by spam.

well, PGP cannot do anything about forgery for those millions of people
who will never use it either, so we are in the same situation, well,
it's more difficult to have all email users to use PGP than all isp's
to use spf. Just count how many people in this list uses pgp and how
many uses spf, taking in account hown many time both systems have been
running, there is a clear advantage in implementation for spf.
