FAQ
Quick answers. No walls of text.
What does DMARC policy do?
DMARC tells receivers how strictly to treat mail that fails SPF and DKIM alignment checks.
What is pct?
pct is the percentage of mail the policy should apply to, often used during staged rollouts.
Does this read the aggregate reports?
No. It checks the published policy and shows the reporting destinations that receive those reports.
