So you want to take a message that exists in an IMAP folder, encrypt the body, 
and replace the existing message?

I don't know if any existing tools that will do that for you. You could 
construct one, of course, but the idea of modifying existing data gives me the 
heebie jeebies, and it fundamentally cannot be a lossless operation; you will 
lose something about the message, whether that's "this message wasn't 
originally encrypted" or something else. Modifying existing messages taints 
them from the perspective of "this message represents a true record".

Rewriting the body and attachments of a message is an approach you're trying 
to use to achieve some other goal...what's that other goal? Perhaps there's a 
better solution.
