I am with Tim here. He isn't suggesting something heavily beurocratic, merely
something simple that could help reduce spam email. It is something that
ISPs could easily do now.

It is important to understand the 'protection' that this would offer:
'owned' PCs for part of spam bot networks, directly sending out email.
The PC owner prob has outlook set up to go via his ISPs MTAs, or gets
mail via some webmail provider.

How would this 'break' the Internet ? An ISP customer would need
to register to say that they send mail directly; everyone else
(the vast majority) would do nothing and notice nothing.
