Obviously, the filtering has to be done at least at one end.  And although it
would be nice if I lived in a world where the ISP originating the mail was
filtering it, I don't live there.

So unless you have a *realistic* proposal to make all the spam-haven ISPs
find religion, see the light, and oust their spammers *without* the "do it or
be blocked everyplace" (your plan B), it's not going to happen in our lifetime...
