Social Networks and Email Whitelists
Here’s the idea:
Use social networks to automatically build email whitelists. How often do you actually get real email from a total stranger. Chances are they know you or know a friend of yours. Your whitelist would be safe as long as nobody in your social network is a friend of a spammer or whitelists a spammer. If that friend does whitelist a spammer, maybe you should reevaluate your friendship
and remove him from you social network.
This would be best implemented by some entity that provides both an email service and a social network service (*cough*Google*cough*).
Or it could be implemented in a P2P fashion. It wouldn’t be as quick or efficient, but it would get the job done. I suppose the depth of the search could be limited to improve performance.

PGP is already built in such a way that you build a circle of trust via signing keys; it probably would work too.

See http://oc-co.org/p2pwl.
Relax greylisting with automatically created whitelists of reputable MTAs; share those whitelists with peer MTAs.
