What DMARC Does

DMARC (Domain-based Message Authentication, Reporting & Conformance) tells receiving mail servers what to do when an email fails SPF or DKIM checks. Without DMARC, anyone can spoof your domain.

DMARC Policy Levels

• p=none — Monitor only (safe starting point)
• p=quarantine — Failed emails go to spam
• p=reject — Failed emails are rejected (maximum protection)
