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
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?
