You don't.  Their upstream(s) in South Africa would bill them for 
outgoing e-mail.

Postage, at least for physical mail, is paid by the sender at the point 
of ingress to the postal network.  Yes, there are ways of gaming 
physical mail, but they are rarely actually used; the challenge of an 
e-mail version of such a system would be making it dirt simple and 
relatively resistant to gaming; or at least making gaming the system 
more expensive than using the system.

And let me reiterate: I don't like the idea, and I don't even think it 
is a good idea.  But how else do we make spamming unprofitable? I'd love 
to see a real solution, but it just isn't here yet.
