We do not serve freemail or large ISPs, so our use case is different than yours. We serve businesses who own their email by law. When an employee sends or receives an email, their employer owns the email, by law. We can, and we do reject spam: the recipient will never see it, by contract. Possibly-spam gets redirected for manual inspection. Last january we scored a perfect zero spam on end-users mailbox, and about 10 manual inspections with zero false positives. If providers would pay their clients for each spam message they deliver, they would be all bankrupt, except us.
