Suppose SPF works and nobody forges mail anymore. Spamers all send mail
using their real domain names. You'll need to subscribe to one or more
blacklists; which ones are you going to choose? And what happens when
the best ones go commercial? To develop a comprehensive reputation
system, you need to somehow snoop on a large portion of the Internet;
under a centralized paradigm, only the largest ISPs or specialized
reporting systems like Vipul's Razor can do this.
One could argue that you're then set up for a natural monopoly, as with
Verisign.
But decentralized paradigms are possible. My argument is that MAPS
proved that the open internet can provide better results than a
commercial service.
It could go either way. I'll find out his concerns at greater depth
later.
