What Is DMARC?

🛡️ Email Authentication Policy

DMARC (Domain-based Message Authentication) tells receiving mail servers how to handle messages that fail SPF or DKIM checks, protecting your domain from spoofing.

📊 Reporting & Monitoring

DMARC provides reporting mechanisms so you can monitor who is sending email on behalf of your domain and identify potential abuse or configuration issues.

✅ What We Check

  • DMARC record existence at _dmarc.yourdomain.com
  • Policy enforcement level (none, quarantine, reject)
  • Alignment mode for SPF and DKIM (relaxed vs strict)
  • Percentage of messages the policy applies to
  • Reporting configuration (rua and ruf addresses)
  • Record syntax and formatting validation
