That's suspiciously close to "Ralph Nader or Ross Perot could have
been elected President, if you ignore the scaling issues". :)
Yes. There's a reason I did not include a ringing endorsement of
sender reputation schemes as the FUSSP; it has colossal inherent
scaling issues; however I believe the 90/10 rule will make it at
least somewhat effective.
Other than that, what Matt said is correct - the problem is that
legitimate mail can come from literally millions of places whose
reputation we have no clue on....
Yes. Sender reputation on an per-ip level is a lot of state.
However; I believe that sender reputation on a swip level may be
attainable, and provide positive value.
