## How to call it through Zero

```sh
zero fetch --capability agentstoolshub-email-security-audit-7592a98d
```

Example prompt: Can you run a full email security audit on acmecorp.com — I need to see the SPF, DKIM, DMARC, and MX status all in one report with a composite score and any fixes I should make?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
