... if Mailman is going to endorse services that way. I don't really think it's a good idea in principle, though. What happens if The Mail Archive goes away or goes proprietary? What are people going to think if The Mail Archive's maintainers hire Barry or Brad? Etc, etc.
(Disclosure: I'm the other archiving service, Gmane.)
I wonder if adding a layer of indirection here would help with these considerations.
That is -- Mailman could have a box saying "archive using external archivers" (without saying which external archivers) that list admins could tick/untick that resulted in a message being sent to a meta-archival site. This meta-archival site would then have a list of external archivers that be notified about the mailing list.
This meta-archive would be run by a third party, and would de-list any archivers that are naughty.
