	Because some MUAs generate message-ids that are likely to 
collide.  For some time now, I've been arguing that they should use a 
hash of the relevant information (maybe all the headers, maybe just 
selected headers, maybe the entire message, whatever is reasonable to 
assume will survive), making sure to at least include the value of 
the "Date:", "Message-ID:", and "Received:" headers as part of that 
input.

	That hash would not change no matter how many times the archives 
are updated, and all published links could remain valid unless that 
particular message itself was deleted from the archives.
