Actually, sender-pays could be implemented at the ISP level.
ISPs would
automatically pay for stamps on outgoing mail, and bill it
back to the
sender.
Sender-pays also doesn't even have to use stamps. It can be
implemented
as a financial arrangement between two mail servers (relays or
otherwise). Mailservers run by entities that trust each other could
even reconcile any handlign fees at the end of the month or
even year.
How does this work when clients use an open access Wi-Fi link
or other situations where free and anonymous access is being granted?
Obviously open servers become a financial liability to the people
running them, but then, that's part of the goal. Nothing stops them from
running free and open servers, but any mail they handle and send on to
other servers will be charged for by the receiving servers, or is simply
not accepted.
I think it would be important for every receiving server to
be able to
set its own charges. These could even be listed in an extended MX
record
I think it even more important that each recipient set their
own rates. Is
a Nobel laureate's email reading time worth the same as a
house wife's
sharing the same ISP?
Well, a recipient that values their time greatly could sign up with a
mail system that charges higher handling rates. Per-recipient rates
might be desireable, but for stopping the mass proliferation of spam,
its not a necessary feature.
