DMARC_POLICY_PARTIAL

warning

The policy applies to only a percentage of messages, so most failures are still delivered.

Working today, and one change away from not working.

How we know

dmarc.test
Policy discovery and semantics. own.dmarc.test publishes its own policy so the exact-name lookup wins; inherit.dmarc.test publishes none so sp= applies. Also multiple records, a policy sharing a name with an unrelated TXT, v= not first, no p=, and an out-of-range pct.
