I agree. It really sucks that a handful of big corps control email now, and we can't all just have our own email servers like in the old days, but the spammers really ruined it. And I don't see how any technical solution could change this: anything that's free and open-source can be easily used by the spammers just like anyone else, and then subverted. The solution to spam isn't technical, it's legislative and judicial, but that's just not possible because they operate across national borders and no one's going to start a shooting war over spam.
