How this service works
Full inbound/outbound email authentication audit for a domain: MX reachability, SPF policy grade, DKIM selector discovery across common selectors, DMARC policy grade, and a composite score with concrete fixes. One call instead of five — the diligence an agent runs before trusting or emailing a domain. Use this when an agent needs to sPF + DKIM + DMARC + MX in one report card.
Output
Returns a structured report containing MX reachability status, SPF policy grade, DKIM selector discovery results across common selectors, DMARC policy grade, an overall composite email security score, and concrete remediation steps for any identified issues.
Example use cases
Pre-send domain trust check
“Before I start emailing leads from venturelab.io, can you audit their domain's email authentication — SPF, DKIM, DMARC, MX — and tell me if they're properly set up or if there are red flags?”
Supplier email legitimacy check
“I just got an invoice from payments@globalsupply.net — can you check if globalsupply.net has proper SPF, DKIM, and DMARC in place so I can tell if this email could be spoofed?”
Own domain deliverability audit
“We're having deliverability problems with our outbound emails from brightwave.io — can you run a full email security audit and show me exactly what's misconfigured, with specific fixes for SPF, DKIM, and DMARC?”
Technical details
Endpoint
GEThttps://agentstoolshub.com/api/v1/security/email-security-audit?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a single-call comprehensive email authentication audit covering MX, SPF, DKIM, and DMARC together, rather than making four or five separate DNS lookup calls. Ideal for agents that need to assess domain trustworthiness before sending email, evaluate a third-party domain's security posture, or diagnose deliverability issues — all without orchestrating multiple specialized tools.
Side effects
- Invalid or non-existent domain returns an error or empty results
- Domain with no DNS records may show all checks as failed
- Rate limiting or timeout if DNS resolution is slow
- DKIM discovery only covers common selectors — custom selectors may be missed
- Network-level errors if the API is unreachable
