DMARC Record Checker: Policy, Alignment and Reporting Analysis
Check the DMARC record of a domain and understand its policy, reporting configuration, alignment settings and enforcement level. DMARC helps protect a domain against spoofing when SPF or DKIM fails alignment.
What is DMARC?
DMARC is an email authentication policy published in DNS. It tells receiving mail servers what to do when a message fails SPF or DKIM alignment, and it can send aggregate reports to the domain owner.
DMARC policy levels
- p=none monitors authentication without enforcement.
- p=quarantine asks receivers to place failing mail in spam or quarantine.
- p=reject asks receivers to reject failing mail.
FAQ
Should every domain have DMARC?
Yes, especially domains used for email, brand communication or transactional messages.
Is p=none enough?
p=none is useful for monitoring, but quarantine or reject gives stronger protection once SPF and DKIM are correct.
