Recommended No CAA records
The BIG Questions

Technical Findings

Email Authentication
SPF (Sender Policy) Configured
DMARC (Policy) Configured Policy: reject
DKIM (Signatures) Not Detected
Mail Posture Email: Enabled
Mail Transport Security
MTA-STS Active Mode: enforce
DANE / TLSA Hosted Provider No DANE/TLSA records found (checked 2 MX hosts)

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) Open Any certificate authority may issue certificates
Priority Actions 4 total Achievable: Low Risk
High Configure DKIM signing

DKIM (DomainKeys Identified Mail) adds a cryptographic signature to outgoing emails, proving they haven't been tampered with. Enable DKIM in your email provider's settings.

selector1._domainkey.yourdomain.com TXT "v=DKIM1; k=rsa; p=<public_key>"
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"
Low Upgrade SPF to hard fail (-all)

Your SPF record uses ~all (softfail), which asks receivers to accept but flag unauthorized senders. Upgrading to -all (hardfail) instructs receivers to reject unauthorized senders outright. Verify all legitimate sending sources are included before switching. Note: if you later enable DMARC enforcement (p=reject or p=quarantine) with DKIM, ~all becomes acceptable because DMARC evaluates both SPF and DKIM alignment before making decisions (RFC 7489 §10.1).

yourdomain.com TXT "v=spf1 include:servers.mcsv.net include:_spf.google.com include:spf.protection.outlook.com -all"
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"
