I had an idea for this where basically you'd put a public key into an 
annotation on a mailbox, and all mail payloads (not the headers) would be 
encrypted. It breaks things like search, but has the benefit you want. But 
it's low on the list of things to do. You could do similar with a sendmail 
milter or somesuch.
