How to read a DMARC policy
DMARC tells receivers how to handle mail that fails aligned SPF or DKIM authentication and where to send reports.
- Policy
- The p tag sets the policy: none (monitor), quarantine, or reject.
- Alignment
- The adkim and aspf tags control whether alignment is relaxed or strict.
- Reporting
- The rua and ruf tags set the addresses for aggregate and forensic reports.
