Technical Findings

Email Authentication
SPF (Sender Policy) Configured
DMARC (Policy) Configured Policy: quarantine
DKIM (Signatures) Not Detected
Mail Posture Email: Enabled
Mail Transport Security
MTA-STS Active Mode: enforce
DANE / TLSA Hosted Provider DANE not available — Microsoft 365 does not support inbound DANE/TLSA on its MX infrastructure
TLS-RPT (Reporting) 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) Open Any certificate authority may issue certificates
Priority Actions 6 total Achievable: Low Risk
Medium Enable DKIM for Microsoft 365

DKIM is only configured for third-party services, not your primary mail platform (Microsoft 365). Enable DKIM signing in Microsoft 365 settings to cover all outbound mail.

Low Upgrade SPF to hard fail (-all)

Your SPF record uses ~all (softfail) and no DKIM signing was detected. Without DKIM, SPF is your only line of defense — upgrading to -all (hardfail) instructs receivers to reject unauthorized senders outright. Verify all legitimate sending sources are included before switching. If you configure DKIM, ~all becomes the industry-standard best practice because DMARC evaluates both SPF and DKIM alignment (RFC 7489 §10.1).

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.westbyforcongress.com TXT "v=DMARC1; p=reject; rua=mailto:dmarc-reports@westbyforcongress.com"
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.

westbyforcongress.com CAA 0 issue "letsencrypt.org"
Low Deploy DANE/TLSA for email transport

DNSSEC is already enabled — you can strengthen email transport security by publishing DANE TLSA records. DANE binds your mail server's TLS certificate to DNS, preventing man-in-the-middle attacks on SMTP connections.

_25._tcp.mail.westbyforcongress.com TLSA 3 1 1 <certificate_hash>
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).
