Email authentication

The basics are in place but can be hardened.

2Pass
2Warning
0Fail
2Not set

SPF

Pass

Authorizes which servers may send mail for the domain

SPF is published and within limits.

Policy: ~all
DNS lookups: 2 / 10

Ends in ~all (softfail): unauthorized senders are marked, not rejected.
Uses 2 of 10 allowed DNS lookups.

v=spf1 include:_spf.google.com include:139603372.spf04.hubspotemail.net ~all

DKIM

Not set

Cryptographically signs outgoing mail (best-effort selector probe)

No DKIM key found for common selectors.

Selectors probed: 32

DKIM selectors cannot be enumerated from DNS, so this only probes well-known selectors. A negative result is not proof that DKIM is missing.

DMARC

Warning

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

DMARC is published but not fully enforcing.

Policy: p=none
Coverage: 100%

Policy p=none: DMARC is in monitoring mode only and does not block spoofed mail.
No rua address: you receive no aggregate reports to monitor abuse.

v=DMARC1; p=none;

MTA-STS

Warning

Enforces TLS for inbound mail and prevents downgrade attacks

MTA-STS is published but not enforcing.

Mode: testing
Max age: 604800s

Policy mode is testing: failures are reported but mail is still delivered.

v=STSv1; id=20250806100000

TLS-RPT

Pass

Receives reports about TLS delivery failures

TLS reporting is configured.

Reports to: mailto:[email protected]

TLS delivery failure reports are being collected.

v=TLSRPTv1; rua=mailto:[email protected];

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.
