hashcash is based on the assumption that CPU time is scarce to
spammers. However spammers use hundred of thousands of trojaned box
nowadays so it is not clear whether this will have any effects on spam.
However, this is completely unpractical for mailing-lists.
Beyond that, I question the ethic of forcing people to waste resource
to send an email.
