In addition, the Message-Id values would have to be filtered, if used as is,
for URL-unfriendly characters (eg, Outlook Express tosses in a couple of $
characters). Just another example of not trusting input from untrusted
The hash of Message-Id:, Date:, and Received: (all of the Received: headers)
would do, except for the case of an insane MTA--the one generating the "top"
Received: header--feeding the same message into Mailman multiple times.
Perhaps a representation of the computer's clock would help there.
There's also the small point that the presence of Message-Id: is a SHOULD,
not a MUST (some compromise in the musty past of the IETF, no doubt).
