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. matto PS: Even though it's painfully obvious, I speak only for myself and no entity currently/previously employing me- Especially those kooks at UCB.
