How about this: I use another company encryption key for auditing
purpose only. When employees send emails, they always use this
encryption key as well as the public keys of recipients for encryption.
This way, I don't have to backup employees' encryption keys, and can
even simplify to use a single key for each employee (this might be
arguable, but it's hard for me to convince myself that it's worthwhile
to use separate encryption key in this case). But I'm not sure if I need
to customize some PGP implementation in order to do so.
