Is this even possible?

Hi,

Decryption alone doesn't need a passphrase - the pass is only used for
decryption and for signing. The unique ID is reasonably easy too - you can
use a serial number (1, 2, 3...), some combination of the date & time, or
the SMTP message-ID.

Are look looking to encrypt all _incoming_ mail to a certain address, or all
_outgoing_ mail?

Peace,
