My documentational comment to myself in my rc that deals with
Message-IDs and RFCs says, "# RFC 2822 strongly recommends M-ID format
(NB: widely ignored)."  Note the part in brackets.  :-)

On that note, I'm doing some Message-ID checks of my own, with good
success.  The *only* false positives I've had so far are from a badly
configured webmail server at rogers.com and a broken SMTP relay at
sympatico.ca.  My recipe is:

  :0 fhw
  *   ^Message-Id: \/.+
  * ! ^Message-Id: 
<[a-z0-9!#%*+/=?^_{|}~.\$\'\`-]+(_at_)[a-z0-9!#%*+/=?^_{|}~.\$\'\`-]+>$
  | formail -A "X-spamtrap: Message-ID violates RFC2822, '$MATCH'"
