Quarantined Messages / Authentication failure / DMARC

Hi, I'm struggling with the quarantine email, since we received a few emails that were sent to quarantined due to "Authentication failure / DMARC".

Im not undestanding at forst it shows: spf=softfail smtp.mailfrom=XXXXXXX@usanainc.com; dkim=none; dmarc=fail (recordpolicy=quarantine)

But then I got this too, everything seems to be fine here:

spf=pass smtp.mailfrom=usanainc.com; dmarc=pass action=none header.from=usanainc.com; dkim=pass header.d=usanainc.com;arc=none

This is what is see on the header:

Authentication-Results: mx-01-us-east-2.prod.hydra.sophos.com; spf=softfail smtp.mailfrom=XXXXXXXX@usanainc.com; dkim=none; dmarc=fail (recordpolicy=quarantine) header.from=usanainc.com

  • The DMARC policy set by the sending company tells you to Quarantine DMARC failures and your policy says 'Conform to Sender Policy' so Sophos is sending DMARC messages from this organization to quarantine if they fail and the headers say dmarc=fail (recordpolicy=quarantine). Sophos does not support ARC checks at this time. Also in order for DMARC to pass either SPF or DKIM must pass. Since SPF encountered a Softfail likely DNS issue and there was no DKIM retrieved because if it was DNS then we couldn't pull the dkim key. I recommend searching our help docs for DMARC and finding the flow charts that walk you through the order of operation. SPF is evaluated first, if it can't be evaluated (softfail) then DKIM, if we can't get dkim verification then neither SPF nor DKIM passed so DMARC is a fail.

Sophos does not support ARC checks at this time. Also in order for DMARC to pass either SPF or DKIM must pass. Since SPF encountered a Softfail likely DNS issue and there was no DKIM retrieved because if it was DNS then we couldn't pull the dkim key. I recommend searching our help docs for DMARC and finding the flow charts that walk you through the order of operation. SPF is evaluated first, if it can't be evaluated (softfail) then DKIM, if we can't get dkim verification then neither SPF nor DKIM passed so DMARC is a fail.
