The old Mailman 2 archives are still available under their old URLs but do not update any more. This is confusing and should be changed so that users are redirected to the new archives of Mailman 3: > https://lists.ipfire.org/mailman3/hyperkitty/list/development@lists.ipfire.org/thread/6K5FXPETPEMKB53TGFVYAPBG4THWFF54/
I have done this by implementing a could of rules in Apache as well as a script that parses the URL to old messages, extracts the Message-Id, calculates the new hash and redirects the user to the new URL. Such fun.
