DMARC p — Policy
What a receiver should do with mail that fails DMARC.
- Required
- yes
- Default
- —
- Valid values
none | quarantine | reject
What it does
p=none only monitors: failing mail is delivered normally and you just receive reports. p=quarantine asks receivers to put failing mail in spam. p=reject asks them to refuse it outright. Since February 2024, Google and Yahoo require any domain sending more than 5,000 messages a day to bulk recipients to publish at least p=none — and that floor is widely expected to rise.
Example
v=DMARC1; p=quarantine; rua=mailto:dmarc@example.com
