How this service works
Collect point-in-time DNS evidence for email authentication controls including MX, SPF, DMARC, CAA, MTA-STS, and TLS reporting.
Output
A point-in-time snapshot of DNS records relevant to email authentication for the queried domain, including MX server configuration, SPF TXT record and policy, DMARC policy record, CAA records, MTA-STS policy, TLS-RPT reporting endpoints, and optionally DKIM records if a selector is provided. Results reflect the live DNS state at the moment of the request.
Example use cases
Vendor email security due diligence
“I'm evaluating a new SaaS vendor — can you check the email authentication DNS records for acmecorp.com and tell me if they have SPF, DMARC with a reject or quarantine policy, and MTA-STS configured?”
Pre-send deliverability audit
“Before we start our email campaign from newsletters.mybrand.com, can you verify our MX, SPF, and DMARC records are properly set up and flag anything that might hurt deliverability?”
Compliance evidence collection
“I need to document the email security posture of techpartner.io for our security audit — can you grab a snapshot of their DMARC, SPF, CAA, and TLS reporting DNS records right now?”
Technical details
Endpoint
GEThttps://trinity-throw-thursday-gravity.trycloudflare.com/x402/email-securityWhen to prefer
Choose this endpoint when you need a comprehensive, single-call snapshot of all email authentication DNS controls for a domain — especially MX, SPF, DMARC, CAA, MTA-STS, and TLS-RPT together. It is ideal for security audits, vendor assessments, compliance evidence collection, or pre-send deliverability checks where you want DNS evidence in one structured response rather than running multiple individual DNS queries.
Side effects
- Domain does not exist or has no DNS records — returns empty or error response
- Invalid domain format provided — likely returns a 400 bad request
- DNS lookup timeout for slow or unresponsive nameservers
- MTA-STS policy document not publicly reachable — partial results returned
- DKIM lookup fails if invalid or non-existent selector provided
- Payment not completed — returns 402 Payment Required before data is returned
