Thank you all for the recommendations. I‘m going to add a semicolon to the _mta-sts entry, just to see if this alone makes a difference to that validator, although RFC8461 describes a trailing semicolon as optional. I could do the same with k=rsa in the DKIM record, but as mentioned by Benny Pedersen this tag is optional as well and rsa is the default value anyway. While I agree that you should be strict in what you send and liberal in what you receive, I‘d say that adding superfluous tags makes a policy less robust and not more, as it introduces additional fields which the other party might trip over. The DKIM record of John Levines domain is reported as invalid too, while you should think that he knows his way around DKIM. So in the end this Google tool might in fact be buggy. — BR Oliver ________________________________ dmTECH GmbH Am dm-Platz 1, 76227 Karlsruhe * Postfach 10 02 34, 76232 Karlsruhe Telefon 0721 5592-2500 Telefax 0721 5592-2777 dmt...@dm.de<mailto:dmt...@dm.de> * www.dmTECH.de<http://www.dmtech.de> GmbH: Sitz Karlsruhe, Registergericht Mannheim, HRB 104927 Geschäftsführer: Christoph Werner, Martin Dallmeier, Roman Melcher ________________________________ Datenschutzrechtliche Informationen Wenn Sie mit uns in Kontakt treten, beispielsweise wenn Sie an unser ServiceCenter Fragen haben, bei uns einkaufen oder unser dialogicum in Karlsruhe besuchen, mit uns in einer geschäftlichen Verbindung stehen oder sich bei uns bewerben, verarbeiten wir personenbezogene Daten.
