  • Caution DMARC policy is p=none (monitor only) DMARC-P-NONE

    Failing mail is still delivered. Fine while collecting reports; move to quarantine or reject once legitimate sources align.

    How to fix: Set p=quarantine (with pct= to ramp), then p=reject.

  • Caution Spoofing protection: monitoring only SPOOF-PARTIAL

    DMARC exists but does not enforce; forged mail is still delivered.

    How to fix: Move DMARC to p=quarantine or p=reject.

  • Note No DKIM key found under common selectors DKIM-NOT-DISCOVERED

    Selectors are chosen by the sender, so a key may exist under a name we did not try. Check a real message header for the s= tag.

  • Note No aggregate report address (rua) DMARC-NO-RUA

    You receive no visibility of who sends as your domain.

  • Note No MTA-STS policy MTASTS-NONE

    Optional; protects inbound mail against TLS downgrade.

  • Pass SPF uses 1 of 10 permitted DNS lookups SPF-LOOKUPS-OK
  • Pass SPF ends with ~all (soft fail) SPF-SOFTFAIL-ALL

    Fine with DMARC enforcing; -all is stricter.

Open relay test owners only

Checks whether each mail server accepts mail for recipients at other domains, which spammers exploit. Because the test sends SMTP commands to your server, it is only offered to verified owners.

Create an account and verify the domain to run this test.
