By allowing the system to cut most of the spam through a simple pull
mechanism, compares very well against today's anti-spam software
model, which not all can afford.
I gather that you are proposing a system in which mail from a particular
domain can only be offered from servers that are somehow authorized by
or related to that domain. If so, that is a huge change to the SMTP
store-and-forward model.
The predecessor to SMTP was a hack layered on FTP which only worked if
the sender and recipient systems were both online at the same time
and could talk directly to each other. SMTP store-and-forward
was a big advance over that a lot of real useful mail systems depend
on being able to deliver mail in multiple stages.
If your idea is that mail from foo.com can only come from a foo.com
server or something like that, you might want to explain how your
proposal differs from RSS, and particularly from the model in the
Tumbleweed patent.

PS:
I guess we are expecting a magic solution that will stop all the spam in a
single go and would not require us from changing our system continuosly.
No we are not, and I have to say that's not a very useful line of argument.
