I am a newbie at this, but I do not see how it is possible to impliment
this. While I suppose it might be possible to make an e-mail user agent
(such as mutt) decrypt GPG | PGP e-mail and display it on a user's screen,
and disable any ability to save the decrypted mail with the mail user agent,
I do not see how it would be possible to stop the reader (i.e., the person,
not the program) from copying and pasting that decrypted email; e.g., by
pressing a save-screen button, or by simply copying and pasting with the
mouse. In other words, even if the software were trustworthy, you are still
at the mercy of the wisdom and intelligence and trustworthyness of the
person receiving it.

So you really must trust, in addition to the GPG programs, the user, and
that is pretty difficult, IMAO, except in certain situations.
