Re: FIDOnet encryption (or lack thereof)

My question is this: how does he know that the mail is encrypted if he's not examining the mail that passes through his system? If he *is* examining the mail that passes through his system, it seems likely that he is violating the Electronic Communications Privacy Act.

With UNIX it's quite simple to grep for "-----BEGIN PGP MESSAGE-----"... and ditch messages that match. I guess one could also run the incoming mail through a spell-checker and reject messages with greater than %99 failure rate. Neither of these require actual examination of the message by a human, neither reveal content of a message to a human.
