DMARC links SPF and DKIM to a policy: what should a receiving server do if authentication fails? With a DMARC record you protect your brand and gain insight into misuse of your domain.

DMARC in three steps

Make sure SPF and DKIM are working properly before enforcing strict policies.
Add a TXT record to _dmarc with for example v=DMARC1; p=none; rua=mailto:dmarc@jouwdomein.nl.
Analyze reports for a few weeks and then scale up to p=quarantine or p=reject.

Policy explained

Check each step carefully and verify the result before continuing.

p=none: monitor only — ideal for getting started.
p=quarantine: suspicious mail to spam.
p=reject: reject inauthentic mail.
