How come SSL certificates in HTTPS transactions can work? Aren't they
reasonably analogous?
No; anybody can generate one. Somebody who wanted billions of valid
ones could just spend a little CPU time.
For most users, all outgping email is already routed through the
ISP's outgoing mail servers, so the extra costs they cause are
limited to the cost of generating the digest and signing it. For
most emails, outgpoing email is not routed through the ISP's
servers, so there is also the additional cost of accepting, storing,
and forwarding the email.
The reason for the discrepancy is probably just spam.
A charging model which allows say 50 emails per day free will
probably leave email free to the average consumer
What stops spammers from using ISPs that allow unlimited email, or
inventing their own "ISPs"?
There is no need to introduce inter-ISP payments for handling
each-other's email traffic distinct from any payments already used
for providing bandwidth and/or handling general internet traffic.
Somebody who hosts a website generally doesn't much care how much
somebody else's customers look at that website (and somebody with
customers doesn't care what websites they look at or how much). But
the whole problem here is that people _do_ care about how much email
gets received.
The european postal union certainly deosn't have such transfer
payments between its members, why should an email system?
If it doesn't, what stops a spammer from joining?
The vast bureaucracy may not be too great a price to pay to
eliminate spam. Government control of our email (through government
regulation of the clearing houses) may not be too great a price to
pay.
It is for something that won't work. (When has a government provided
anything else?)
