Executive's DNS Intelligence Brief

Board-level domain security assessment — ietf.org

11 Feb 2026, 22:34 UTC · 9.9s · SHA-3-512: 41da✱✱✱✱ Verify
Golden-fixture baseline domain. This domain is part of the golden-fixture corpus: its recorded scan snapshot is the tool's regression baseline. A scan of it reproducing the snapshot is the baseline returning its own value — expected agreement, not independent validation.

Technical Findings

Email Authentication
SPF (Sender Policy) Configured
DMARC (Policy) Partial Policy: none Monitor Only
DKIM (Signatures) Not Detected
Mail Posture Email: Monitoring
Mail Transport Security
MTA-STS Partial
DANE / TLSA Active
TLS-RPT (Reporting) Not Configured
Mail Transport Not Enforced Policy-assessed
DNS Security
DNSSEC Signed & Validated
DNSSEC fully configured and validated — AD (Authenticated Data) flag set by resolver 8.8.8.8 confirming cryptographic chain of trust from root to zone (RFC 4035 §3.2.3)
NS Delegation Healthy
Brand & Certificate Controls
BIMI (Brand Logo) Configured
CAA (Certificate) Open Any certificate authority may issue certificates
Priority Actions 4 total Achievable: Low Risk
High Escalate DMARC from monitoring to enforcement

Change your DMARC policy from p=none to p=quarantine (then p=reject). Review your DMARC aggregate reports first to ensure legitimate senders pass authentication.

_dmarc.ietf.org TXT "v=DMARC1; p=quarantine; rua=mailto:dmarc-reports@ietf.org"
Medium Deploy MTA-STS policy

Publish an MTA-STS DNS record and host a policy file at https://mta-sts.ietf.org/.well-known/mta-sts.txt. This tells senders to require TLS when delivering mail to your domain.

_mta-sts.ietf.org TXT "v=STSv1; id=20240101"
Low Add CAA records

Publish CAA DNS records to restrict which Certificate Authorities can issue TLS certificates for your domain. Specify your preferred CA (e.g., letsencrypt.org, digicert.com). CAA is advisory — CAs must check it before issuing, but absence means any CA can issue.

ietf.org CAA 0 issue "letsencrypt.org"
Low Configure TLS-RPT reporting

TLS-RPT (TLS Reporting) sends you reports about TLS connection failures when other servers try to deliver mail to your domain. Helps diagnose MTA-STS and STARTTLS issues.

_smtp._tls.ietf.org TXT "v=TLSRPTv1; rua=mailto:tls-reports@ietf.org"
