DMARC

Warning

Tells receivers what to do with mail that fails SPF and DKIM

DMARC is published but not fully enforcing.

Policy: p=reject
Coverage: 100%

Policy p=reject: failing mail is rejected outright.
No rua address: you receive no aggregate reports to monitor abuse.

v=DMARC1;p=reject;

MTA-STS

Not set

Enforces TLS for inbound mail and prevents downgrade attacks

No MTA-STS policy. Inbound mail can be delivered without TLS.

TLS-RPT

Not set

Receives reports about TLS delivery failures

No TLS-RPT record. You get no reports about failed TLS delivery.

BIMI

Not set

Displays your verified brand logo in supporting inboxes

No BIMI record. No brand logo is published for inboxes.

Checks query live DNS over Cloudflare and the public MTA-STS policy endpoint. DKIM selectors cannot be listed from DNS, so DKIM detection probes common provider selectors only.
