Section 01

Executive Summary

Only SPF is configured. Your domain needs SPF, DKIM, and DMARC working together to prevent spoofing.

Top Priority Actions

  1. DKIM: Ensure your email provider has published DKIM keys. If using a custom selector, DKIM may still be active.
  2. MTA-STS: Publish an MTA-STS TXT record and host a policy file at https://mta-sts.yourdomain/.well-known/mta-sts.txt.
  3. TLS-RPT: Publish a TLS-RPT record to receive reports when sending servers fail to establish encrypted connections.

DMARC. Domain-based Message Authentication, Reporting & Conformance

Monitor OnlyRFC 7489
19 / 35

DMARC policy is set to none (monitor only). Unauthorized emails are still delivered.

DNS Record

v=DMARC1; p=none; sp=none; rua=mailto:a@dmarc.facebookmail.com
Recommendation: Progress to p=quarantine and then p=reject once you have identified all legitimate senders via RUA reports.

Recommendation: Consider tightening to -all for stricter enforcement alongside your DMARC policy.

Section 05

DKIM. DomainKeys Identified Mail

Not DetectedRFC 6376
0 / 20

No DKIM record found for common selectors on fbcdn.net. DKIM may use a custom selector that could not be auto-detected.

Recommendation: Ensure your email provider has published DKIM keys. If using a custom selector, DKIM may still be active.

Section 06

Transport Security

Transport-layer email security protocols that protect messages in transit between mail servers.

MTA-STS Mail Transfer Agent Strict Transport Security

Not ConfiguredRFC 8461
0 / 10

No MTA-STS record found for fbcdn.net. Inbound SMTP connections are vulnerable to TLS downgrade attacks.

Recommendation: Publish an MTA-STS TXT record and host a policy file at https://mta-sts.yourdomain/.well-known/mta-sts.txt.

TLS-RPT TLS Reporting

Not ConfiguredRFC 8460
0 / 5

No TLS-RPT record found for fbcdn.net. TLS delivery failures are invisible.

Recommendation: Publish a TLS-RPT record to receive reports when sending servers fail to establish encrypted connections.

BIMI Brand Indicators for Message Identification

Not FoundRFC 9495
0 / 5

No BIMI record found for fbcdn.net. Brand logo will not appear in supporting email clients.

Recommendation: Publish a BIMI record with your brand SVG logo. Requires DMARC at p=quarantine or p=reject with pct=100.
