DMARC (Policy) Partial Policy: none Monitor Only
DKIM (Signatures) Configured
Mail Posture Email: Monitoring
Mail Transport Security
MTA-STS Partial
DANE / TLSA Hosted Provider DANE not available — Google Workspace does not support inbound DANE/TLSA on its MX infrastructure
TLS-RPT (Reporting) Not Configured
Mail Transport Not Enforced Policy-assessed
DNS Security
DNSSEC Partial
DNSSEC not configured - DNS responses are unsigned
NS Delegation Healthy
Brand & Certificate Controls
BIMI (Brand Logo) Not Configured
CAA (Certificate) Open Any certificate authority may issue certificates
Priority Actions 5 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.knoxminerals.com TXT "v=DMARC1; p=quarantine; rua=mailto:dmarc-reports@knoxminerals.com"
Medium Deploy MTA-STS policy

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

_mta-sts.knoxminerals.com 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.

knoxminerals.com 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.knoxminerals.com TXT "v=TLSRPTv1; rua=mailto:tls-reports@knoxminerals.com"
Low Enable DNSSEC

DNSSEC (DNS Security Extensions) cryptographically signs DNS responses, preventing attackers from forging DNS answers. Contact your DNS hosting provider to enable DNSSEC signing.
