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 structured JSON snapshot of point-in-time DNS evidence for the queried domain, including MX records, SPF TXT record, DMARC policy record, CAA records, MTA-STS policy details, and TLS reporting (TLS-RPT) configuration — all source-linked to actual DNS lookups.
Example use cases
Pre-send deliverability audit
“Before we launch this email campaign, check the DNS email authentication setup for ourdomain.com — I need to see if SPF, DMARC, and MX are all properly configured.”
Third-party vendor security review
“We're onboarding a new vendor at vendorcompany.com — can you pull their email security DNS records so I can verify they have proper DMARC and MTA-STS policies in place?”
DKIM selector verification
“Can you check the email security DNS records for acme.com and inspect the DKIM selector 'google' to confirm it's correctly published?”
Technical details
Endpoint
GEThttps://phases-prot-shine-royal.trycloudflare.com/x402/email-securityWhen to prefer
Choose this endpoint when you need a comprehensive, multi-record email authentication DNS audit in a single call rather than querying individual record types separately. It is ideal for security reviews, onboarding due diligence, deliverability troubleshooting, and compliance checks where MX, SPF, DMARC, CAA, MTA-STS, and TLS-RPT evidence must all be gathered together as a point-in-time snapshot. Prefer this over general DNS lookup tools when the focus is specifically on email authentication controls.
Side effects
- Domain not found or non-existent — returns empty or error response
- DNS lookup timeout for specific record types — partial results returned
- Malformed domain input — validation error
- DKIM selector not found — selector-specific record returns null or error
- MTA-STS policy fetch fails if policy file is unreachable
- Rate limiting if too many requests in quick succession
