It varies widely. Agreed. Around here (Ithaca NY) it's probably on the order of 20% due to all of the Cornell grads who still use their cornell.edu address. > Pick a solution or solutions that you like, or not.

That's why for widespread deployment we have to look at the small minority of schemes that don't break legitimate mail. That's why I'm looking at CSV, which makes it easier to assign reputation to sending hosts, and domainkeys (or whatever it's called when they're done mixing in IIM) which if sensibly used makes it easier to whitelist mail from people you like.
