Well, I disagree with your premise: it will only catch accidental or
incompetent attempts to ship proprietary IP through email.

Many people. The FBI recently has had some publicity about a similar scheme.

Use qmail's QUEUE_EXTRA feature to send a copy of every message to a given
alias, controlled by a .qmail file. In that file, pipe messages to a script
which uses something (mess822, perl, awk, you name it) to record the
envelope sender (Return-Path:), envelope recipient (hmmm, a bit trickier,
probably have to parse To:, etc), subject, and date.
This is documented in Dan's qmail FAQ.
