What the author says it does
Execute a phased DMARC rollout by inventorying sending sources, configuring SPF/DKIM alignment, and progressing DNS policy from p=none monitoring through p=quarantine to p=reject enforcement, ensuring all legitimate email sources authenticate before unauthorized senders are blocked. Use when deploying or advancing an organization's DMARC anti-spoofing posture, or when meeting bulk-sender authentication requirements from Google and Yahoo.
