You're failing GMail DKIM as "No valid DKIM" in Authentication-Results header

Apparently in an attempt to address this https://userforum-en.mailbox.org/topic/2301-inconsistent-authentication-results-of-mailbox-servers-seems-potentially-risky you're now failing GMail/Google Mail via an "No Valid DKIM" line in Authentication-Results despite DKIM being present. Furthermore, there is no dkim=... entry at all in the Authentication-Results header anymore, only a dmarc=... entry. For a missing DKIM there should be dkim=none or similar. This seems like quite a mess. Also, it says "incoming_mbo" instead of a proper "something.mailbox.org" server name clients can trust.

I hope this can be fixed timely, it makes filtering malicious e-mail almost impossible based on this header.
