Technical Findings

Email Authentication
SPF (Sender Policy) Configured
DMARC (Policy) Partial Policy: none Monitor Only
DKIM (Signatures) Configured
Mail Posture Email: Monitoring
Mail Transport Security
MTA-STS Partial
DANE / TLSA Not Configured
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) Not Configured
CAA (Certificate) Configured
Priority Actions 3 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.freebsd.org TXT "v=DMARC1; p=quarantine; rua=mailto:dmarc-reports@freebsd.org"
Medium Deploy MTA-STS policy

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

_mta-sts.freebsd.org TXT "v=STSv1; id=20240101"
Low Configure TLS-RPT reporting

Your domain has DNSSEC + DANE — the strongest email transport security available. TLS-RPT adds operational visibility by reporting when sending servers fail DANE validation or encounter STARTTLS issues delivering to your MX hosts. It does not add security — it monitors the security you already have.

_smtp._tls.freebsd.org TXT "v=TLSRPTv1; rua=mailto:tls-reports@freebsd.org"
Appendix — Additional Resources

Full technical details including raw DNS records, DKIM public keys, IP/ASN mappings, resolver consensus evidence, and verification commands are available in the Engineer's DNS Intelligence Report.
