Your Domain Trust Score is a 0-100 number combining policy strength, alignment rate, supporting record health, and behavioural signals.
Bands
- 0-39 (Poor) — no DMARC, p=none with weak SPF, or active spoofing on the wire
- 40-59 (Fair) — p=none with reasonable alignment, or p=quarantine without supporting records
- 60-79 (Good) — p=quarantine + healthy SPF/DKIM/MTA-STS, or p=reject with minor gaps
- 80-100 (Excellent) — p=reject + aligned subdomain policy + MTA-STS enforced + TLS-RPT live
What moves it most
- Going from p=none to p=quarantine: roughly +15 points
- Going from p=quarantine to p=reject: roughly +10 points
- Adding MTA-STS in enforce mode: +5
- Closing all unaligned legitimate senders: +5 to +15
p=none always caps you
A domain with p=none scores 0 on the policy axis and is hard-capped at 59 (Fair) regardless of how clean its alignment is. We do not let p=none reach Good.
