Policy Deployment Strategy

1

Start: p=none

Monitor email authentication for 2-4 weeks without affecting delivery. Review reports to identify all legitimate email sources.

2

Next: p=quarantine

Failed emails go to spam folders. Monitor deliverability and ensure no legitimate emails are quarantined.

3

Final: p=reject

Failed emails are completely blocked. This is the strongest protection but requires confidence in your setup.
