Yes, I'm thinking that is the "Right" approach. However, the envelope
sender is easily available, and is always just a functional address,
without comments. I'm not sure how to parse the headers of the message
for unqualified senders from bash....

Ugh. The main problem with that is the information that is needed to do
that lookup (eg, what UUCP host originated this message) is only
available when my rmail script is running...
