allows you to reject faked bounces
Sorry, I can't reject anything at all, I'm only a POP3 user.
With SPF I can define which IPs are allowed to send mail from
my domain, and this allows all recipients to reject fakes, as
far as they support SPF and interpret "-all" as REJECT.
For a short period this will "only" reduce the number of
useless bounces. But the spammers will soon learn that it's
a really stupid idea to forge addresses in domains protected
by SPF, and then the useless bounces will completely stop.
That's the theory, AFAIK, and Seth's example would break it.
