You'd put something into the mail message itself that would tell
it
"don't encrypt this" and/or "don't sign this". Hmm... you'd need to put in messages to be signed and/or encrypted your passphrase, or have it gotten some other way... which doesn't look very safe.
exmh on Unix systems goes the other way. It adds a header line that includes the sender and recipient, plus the action to be performed ("encrypt," "sign" or "encryptsign"). No header, no encryption/signature. I'm reasonably sure it strips off that line before it passes the message off to sendmail -- but I usually don't send messages to myself that way. :- ) For incoming mail, it looks for standard PGP structure and figures out what it needs from the user. If, for instance, you don't have a public key on your keyring, it allows you to send a mail message to a server to grab it - - - otherwise it performs the operation and shows you the results. If what you're doing requires a password (signing or decrypting), it pops up a window to ask you for it. When it's done, it prompts you to press Return and disappears. It was written in tcl/Tk, but some of it may be applicable for what you want to do. (Sorry, I'm not an expert on either.)
