        My thoughts, after a 10 minute perusal of hashcash :)
Hashcash is (imho) a stupid waste of time. It unfairly penalises people with slow computers who might want to run a mailing list (me!) while barely slowing any spammer who happens to control a vast network of virus-infected home computers (most of them). And, like most spam 'solutions' it requires a complete reimplimentation of the entire mailsystem. If you think that 'raising the cost of mail' is the right approach, tiergrube(sp?) would be a much fairer (and more transparent) way of doing it.
