DMARC Policy Levels

  • p=none: Monitoring only. Spoofed emails reach inboxes. No protection.
  • p=quarantine: Spoofs go to spam. Partial protection but still visible to recipients.
  • p=reject: Spoofs blocked at the gateway. Full domain protection.

Google and Yahoo's 2024 sender requirements mandate DMARC p=quarantine or p=reject for bulk senders. Failure to comply results in delivery failures at Gmail and Yahoo Mail.
