The user manual and admin manual are missing directions on how to 
deploy/use PGP encrypted emails.

The user manual should include how to set the public key. Setup
on the client side to PGP sign the email should not be included.

Admin manual should discuss settings and what needs to be set up
in the config.ini file to sign/encrypt emails.

From what I just scanned it looks like the key needs to be on the 
filesystem??? I would expect pgp pub keys to be uploadable via the
web interface.
