Here's one I'm posing as a question for everyone...

I'd like to find a way to encrypt email.  However, I have 2 desktops I'm 
using in 2 locations plus a laptop.  All three are accessing email 
through IMAP, so the mail is stored on 2 different mail servers.

The end result email would have to have some kind of decryption client 
available on Windows as well as OS X and Linux.

What would be a good solution, and what will it involve to implement and 
use it?

The goal is to have the encrypted text on the mail server and decrypt it 
at reading time, so if it's read on the mail server by a third party the 
message will be gibberish.
