An implicit assumption in this discussion is that in the ePostage
model money must flow from sender to receiver.
Well, yes. The basic problem with spam is the imposition of cost on
unwilling recipients; I see little point in epostage that pays some
other party, as then the recipient has still lost; it's just that
someone else has benefited instead. I fail to see how this improves
matters significantly.
It improves matters by significantly raising the transaction cost for
the spammer to send mail (currently ballpark 0.01 cent), thus reducing
the attractiveness of this advertising medium.
