Look up by Message-ID? <http://mid.mail-archive.com/20200506141139.GJ2375@tucnak>, for example. See <https://en.wikipedia.org/wiki/Message-ID>, etc. The idea is that for all practical purposes, Message-IDs are "sufficiently unique". (Compare conceptually to the Git SHA-1 hashes.) Such a service is not currently available on sourceware, but it'd be possible to implement: as messages come in, you'd build a database mapping from the Message-ID header to "current Mailman's Pipermail URL". (That's one reason why when posting such links I used to use Gmane's Message-ID lookup, now using The Mail Archive's. The other reason is that compared to Mailman's Pipermail these services don't artificially break discussion threads at month boundaries.) By the way, the public-inbox software (<https://public-inbox.org/README.html>), as recently mentioned in a different thread discussing deficiencies of Mailman's Pipermail, also does support this: <https://public-inbox.org/libc-alpha/129c8494-bfd0-87f0-ddb5-e56f6d4a6...@gotplt.org> (random example). (I have not yet really looked into that software myself, but from the little I read about it, it seems conceptually simple, "easy", good.) If there's sufficient interest (users) and commitment (overseers), we could install this on sourceware, in addition to what we've currently got?
