Common DMARC Record Issues

Required Tags

  • v=DMARC1 - Must be the first tag
  • p= - Required policy tag (none/quarantine/reject)

Common Mistakes

  • Missing required tags (v= or p=)
  • Incorrect tag ordering (v= must be first)
  • Invalid email addresses in rua= or ruf= tags
  • Invalid percentage values (must be 0-100)
  • Malformed URI formats in reporting tags

Best Practices

  • Include both rua= and ruf= tags for comprehensive reporting
  • Use appropriate intervals (ri=) based on your monitoring needs
  • Consider implementing subdomain policies (sp=) if needed
  • Start with p=none and gradually increase enforcement
  • Use appropriate failure reporting options (fo=)
