If an enduser gets a bill for sending several thousand e-mails because they got owned by a botnet they're going to do something about it; get enough endusers with this problem and you'll get a class-action suit against OS vendors that allow the problem to remain a problem; you can get rid of the bots.  This will trim out a large part of spam, and those hosts that insist on sending unsolicited bulk e-mail will get billed for it.  That would also eliminate a lot of traffic on e-mail lists, too, if the subscribers had to pay the costs for each message sent to a list; I wonder what the cost would be for each post to a list the size of this one.  If spam ceases to be profitable, it will stop.

Actually, a variant on that that might be acceptable… Make e-postage a deposit-based thing. If the recipient has previously white-listed you or marks your particular message as “desired”, then you get your postage back. If not, then your postage is put into the recipients e-postage account to offset the cost of their emails.
