Wrong. We already solved this problem on Cypherpunks a while back. A spammer will have to pay to send you spam, trusted emails do not. You'll have a settable Spam-barrier which determines how much a spammer has to pay in order to lob spam over your barrier (you can set it to 'infinite' of course

Bingo, that's the whole point, spam doesn't get "fixed" until there's a robust economics available to fix it. So long as it's treated merely an annoyance or security flaw there won't be enough economic backpressure. On February 16, 2005 at 18:38 [EMAIL PROTECTED] (Peter Gutmann) wrote: > Barry
