Hehe.
To be honest, I came up with my "^From: " method sometime back in 1990
for a script I was using to check counts in multiple inboxes and have been
using the same method ever since. I knew it had its limitations but never
was bothered enough to examine it more. I still use the exact same
shell script today, but I updated it per this coversation.
The last modified date on what I was using was March 3, 1990. *snicker*.

If you're trying to count messages in a file in mbox format, the regex
for the message delimiter should be "^From ". This is not the same as the
"From:" header usually displayed by MUAs. Note that this may also subject
to error if your LDA does not do "^From " escaping in message bodies -- see
the part about explicit delivery in the MISCELLANEOUS section of the
procmail
man page.
Yes, certainly, you're right. I wasn't touting that line I added
as the right answer. It was just how I'd rewrite Robert's, if
I were Robert and really, really wanted to use From: for some
strange reason instead of From_. Sorry I wasn't clear. Again,
the "formail -s echo < $MAIL | wc -l" is what got my vote.
