Realistically speaking, did you not expect that to be inevitable?

As access to the internet increases, the chances of SMTP scaling to 
prevent spam decreases. And as IP's become more numerous and 
'chuckable' (so much more so with IPv6 around the corner), the idea of 
a blacklist becomes ever more useless.

What we need is a new mail protocol.. [But people have been saying 
that for decades now]
