This doesn't work with maildirs. (NB: I am unfamiliar with "BSD
countmail". I use my own implementation of "frm", but not often,
preferring a "checkmail" script that tells me the latest message in
a group of mail boxes and works by parsing the procmail log for
delivery details instead of looking at the actual mail boxes. This
prevents reading the message from resetting the mail file atime.

I have _immediate_ red flags going up. I don't know specifics of how
Python's "re.compile" works, but in normal Unix regex language the
"[^Mail System Internal Data]" bit is a character class that contains
the invert of the characters within. I am dubious that Python has
redefined what "[^...]" means.

doesn't care much how _many_ messages there are
