How this service works
Email authentication audit of a domain: MX, SPF (lookup count and policy), DMARC policy and reporting, DKIM on common selectors, MTA-STS, TLS-RPT and BIMI, graded A-F with fixes. Use for deliverability and phishing-risk checks.
Output
Returns a structured report covering MX record details, SPF record text with lookup count and policy strictness, DMARC policy tag and reporting addresses, DKIM check results on common selectors, MTA-STS policy mode, TLS-RPT record presence, BIMI status, an overall letter grade from A to F, and a list of specific remediation steps to improve the configuration.
Example use cases
Pre-send deliverability check
“Before we launch this email campaign, can you audit sendgrid.net's email authentication setup — check SPF, DMARC, DKIM, and MTA-STS — and tell me if anything could hurt deliverability?”
Phishing risk assessment for vendor domain
“We're about to wire money based on an email from payments.acme-vendor.com — can you check whether that domain has proper DMARC enforcement so I can tell if it's a spoofing risk?”
Email security compliance audit
“I need a full email security audit of our company domain mybusiness.io — give me the A–F grade, check all the records including BIMI, and list exactly what we need to fix.”
Technical details
Endpoint
GEThttps://bess-x402.onrender.com/v1/web/email-security?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single-call, multi-protocol email authentication audit covering SPF, DMARC, DKIM, MTA-STS, TLS-RPT, and BIMI in one response with an A–F grade and actionable fixes. Prefer it over raw DNS lookup tools when you want a synthesized security posture rather than individual record lookups, or when assessing deliverability and anti-phishing posture for a domain you don't control.
Side effects
- Domain does not exist or has no DNS records — returns empty or error response
- Domain has no MX records — partial results with degraded grade
- DNS timeout for certain record types — may return incomplete results for affected checks
- Invalid domain format provided — returns validation error
- Rate limiting or infrastructure issues on the provider side — HTTP 429 or 5xx response
