Hoping to make the new VM mail9 a rebuildable testbed/CI host (details
are in uccpass).

bookworm is nearly here - however... mailman2 in Python3 is a thing that
we could use for a while:

https://github.com/jaredmauch/mailman2-python3
https://lists.debian.org/debian-python/2022/08/msg00075.html
https://lists.debian.org/msgid-search/25347.28199.349250.665222@chiark.greenend.org.uk

One of the things that stop mailman3 being an easy drop-in upgrade
is the change in archiving - I'd like to keep our current pipermail
structure for at least a while, even if we were to add something new,
like HyperKitty. Both are available in mailman2, above, and I think at
least pipermail can be and has been plucked out and run independently,
which would make things simpler.

https://github.com/jaredmauch/mailman2-python3/blob/main/Mailman/Archiver/pipermail.py
https://github.com/jaredmauch/mailman2-python3/blob/main/Mailman/Archiver/HyperArch.py

Is the above msgid-search a Debian tweak? That'd be a lovely feature to add,
I'm not sure exactly where all the code is for that.
