DMARC policies are crucial for preventing domain spoofing and malicious emails. Domain owners have three policy options: p=none (for testing only), p=quarantine (moves failed emails to spam/quarantine folder), and p=reject (permanently rejects unauthenticated emails). The p=reject policy offers the strongest protection. Starting with p=none and gradually escalating to p=quarantine before p=reject is recommended for careful implementation.
