Quarantined Messages / Authentication failure / DMARC

Tino Korth | DrehPunkt GmbH

Hello Sophos Email friends,

I'm struggling with the quarantine because there are lots of emails quarantined by "Authentication failure / DMARC".

As an example I have an email that is OK and that looks pretty good, but it's quarantined by DMARC.

The sending server is OK: https://mxtoolbox.com/SuperTool.aspx?action=mx%3akaffee-partner.de&run=toolpage 

SPF is OK: https://mxtoolbox.com/SuperTool.aspx?action=spf%3akaffee-partner.de&run=toolpage

DMARC is set, but no policy is activated, so it should be OK: https://mxtoolbox.com/SuperTool.aspx?action=dmarc%3akaffee-partner.de&run=toolpage 

The mail header shows

Authentication-Results: mx-01-eu-central-1.prod.hydra.sophos.com; spf=none smtp.helo=mail2.kaffee-partner.de; dkim=none; dmarc=fail (recordpolicy=none) header.from=kaffee-partner.de

How can I get more informations why the mail was quarantined by DMARC policy?

Best regards

Tino
