Authentication-Results-Original email header
emails from my tenant have started getting the below Authentication-Results-Original: dkim=none (message not signed) header.d=none;dmarc=none action=none header.from=domain.com; as well as ...
Hi, thank you again LeonPavesic
I've checked SPF, DKIM and DMARC config and everything is correct. I've added the results from mxtoolbox analyse header, my domain as you can see pass SPF, DKIM and DMARC. However it doesn't when I check on MS Defender, as shown in the screenshot I attached earlier.
Comparing a few email headers, it looks like MS Defender was taking results from ''Authentication-Results-Original" rather than from "Authentication-Results"
Finally, a really professional answer would be required instead of pushing standard HowTos to hunt for community achievements ..... and silence.
What a shame.
