Mailman 3 already has code to add this X-Message-ID-Hash header, and
integrate with mail archiving tools.

Tilman, thanks for those links.
I thought the base-32 encoded hash of Message-Id discussed in
[http://wiki.list.org/display/DEV/Stable+URLs] gives us a
straightforward and effective solution to the problem. Ten characters
or so should be plenty. This would produce URLs like,
[http://lists.wikimedia.org/pipermail/wikitech-l/2012-August/OHRDQGOX35.html]
We could prefix these with a parent directory that serves as a
versioning scheme for our hash, allowing us to create forwarding rules
if the permalink rules change in the future. For example (and I have
no experience, this might not work), we can generate an .htaccess at
the root of old archive directories, which redirects each of the old
sequential URLs to the new, hashed location.

I was told yesterday that the mailman/pipermail archives were broken,

This is pretty devastating. It's difficult to overstate the
importance of
Mailman archives in documenting Wikimedia's history (or even history
before
Wikimedia was a concept). I've come across links such as the one at
https://en.wikipedia.org/wiki/Wikipedia:Tim_Starling_Day that I
can't even
find anywhere in the Mailman archives any longer. :-(

Many historical Signpost articles are affected as well:

BTW, here's Brion dreaming about a stable archiving system in 2007 ...

In the same year, the lead developer of Mailman said that fixing this
problem of breaking URLs was absolutely critical
(http://mail.python.org/pipermail/mailman-developers/2007-July/019632.html
) and some ideas were thrown around
(http://wiki.list.org/display/DEV/Stable+URLs ), but apparently this
huge data integrity problem still hasn't been solved.
