DMARC policy (p=none, p=quarantine, p=reject)

Also written: p=, p=none, p=quarantine, p=reject, monitoring mode, DMARC enforcement

The p= tag tells receivers what to do with email that fails DMARC: p=none only sends reports (fake email is still delivered), p=quarantine usually sends it to spam, and p=reject refuses it at delivery. Roll out from none to reject; quarantine and reject count as enforcement, which BIMI needs.
