Another compelling reason for micropayments. I'd love to not accept email
from unknown senders without a $0.01 micropayment attached. Friends
and family get in free (or I'll gladly make the payment to send to
them, and let the dynamics of email sort it out and not wory about $0.25).
This assumes that there's no per-transaction charge - the micropayments
would have to be some tiny cryptographic attachment to the message that
I could redeem them in bulk once per year.
The problem with penny black is that it makes you spend resources
to email me (good), but it doesn't give those resources to me (or the
government/post office) for my trouble (bad). I'd be happy to have
no spam, even at the cost of wasted resources, but I'd be equally or
more happy to be able to specify the price I charged for receiving
spam. Too much spam? Charge $0.25. Even at a penny per mail, I'd
receive about $1000/year for my troubles. That kind of seasoning
would make spam taste a lot better.
Can SMTP be munged to do this kind of negotiation? A sender shouldn't
have to attach money to an email if the receiver doesn't demand it,
and also shouldn't have to worry about it within certain ranges
("I'll pay up to $0.02 per email up to 100 per day, no questions asked").
Or do we need the ECLS (email cost lookup service) - I send in my
public key and the recipient, and get back a number that I have to pay.
Who _are_ the endpoints in this kind of negotiation? Now that we're
talking about money, it's a more serious question.
How do mailing lists fit in to this? :-)
How would ISPs/etc make an extra buck off of it?

I do not accept unsolicited commercial email. Do not spam me.
