I took the opportunity of the slow season to make some changes to the mail server configuration: it's moved to another server and the mailing lists are now driven by mailman3 (before: mailman2) with hyperkitty as mailing list archive system (before: pipermail).

I'm still importing and otherwise handling the archives, but the mailing list should work now. For you, I hope that the only impact will be that mailman3 has a new user management concept that manages users on a per-server basis and not per mailing list like mailman2 did. This means that your mailman credentials are void and you'll have to request new ones.
