DMARC considerations

DMARC stands for Domain Message Authentication, Reporting, and Conformance is another email validation system (similar to DKIM) designed to detect and prevent email spoofing. Publishing a DMARC record will help organizations see if anyone is trying to spoof their domain.

 

DMARC policies can tell ISPs how to handle the incoming mail when the email appears to be spoofed. While the intention of DMARC policies is overall good, senders should be careful to check how the policy might affect the delivery of emails they are sending.

  • p=none: The none policy can be a very useful tool to find out where DKIM or SPF are broken. In terms of deliverability, it should have little to no direct effect.
  • p=quarantine: The quarantine policy will soft bounce mail when DKIM or SPF is broken. It would be in your best interest to publish a custom DKIM for this policy.
  • p=reject: The reject policy tells the ISP to completely fail unauthenticated mail. There is no delivery or response sent back to the sender. This policy is not recommended for senders using WordFly.

 

Example DMARC results:

 

dmarc=pass (p=QUARANTINE sp=QUARANTINE dis=NONE)

Planning to use DMARC

We recommend using a publish a custom DKIM if you plan to publish DMARC with a quarantine policy.

 

Email us to request a DKIM record for your domain. We will help run verification tests to confirm the DKIM is passing.
