Mail Transport Not 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 6 total Achievable: Low Risk
Medium 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).

yourdomain.com CAA 0 issue "letsencrypt.org"
Medium Deploy MTA-STS policy

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

_mta-sts.yourdomain.com TXT "v=STSv1; id=20240101"
Low Upgrade DMARC to reject policy

Your DMARC policy is quarantine — spoofed messages are flagged. Upgrading to p=reject blocks them entirely. Review aggregate reports to confirm legitimate senders are aligned.

_dmarc.yourdomain.com TXT "v=DMARC1; p=reject; rua=mailto:dmarc-reports@yourdomain.com"
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.yourdomain.com TXT "v=TLSRPTv1; rua=mailto:tls-reports@yourdomain.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.

Low Configure BIMI brand logo

Publish a BIMI DNS record pointing to your brand logo (SVG Tiny PS format). For full support in Gmail, you will also need a Verified Mark Certificate (VMC).

default._bimi.yourdomain.com TXT "v=BIMI1; l=https://yourdomain.com/logo.svg"
