Shouldn't this also scrub Authentication-Results then?

I don't see Authentication-Results, there is nothing that adds them. OpenDKIM is not configured to add them apparently.
Above the Content-Type header (the last one added by the client) I only see DKIM-Signature, Received and Return-Path. Maybe Received and Return-Path can be removed to reduce the amount of stored metadata further. These headers come from the receiving server.

Does this actually work? I tried applying this to my server but I still see the DKIM-Signature header in the maildir files on disk |

Local mails didn't get DKIM-Signature stripped and this broke federation for me |
