I've seen a lot of good responses to this thread, but one thing is clear; 
some people are giving suggestions for encrypting the message and some for 
signing the message.  What is it you are trying to achieve, hiding the 
data or protecting the data from being tampered with?

You wouldn't need to encrypt *and* sing a message.

Actually encrypting messages with pgp would prevent them from being read 
but would be a total pain as you would need their public key first (i 
don't think pgp does symmetric encryption).  

To sign the email, you'll just need to attach the digital signature as an 
attachment with the right MIME type.  The email itself will still be 
readable.  This only makes sense if people are actually going to check the 
signatures, how many people do that.  I've seen a few signed messages on 
the list, but never bothered to ask people for their public key to verify 
it.
