How this service works
Email security of a domain: MX, SPF (final policy, multiple-record and lookup-limit problems), DMARC (policy, subdomains, reporting), MTA-STS, TLS-RPT and BIMI, with a score and recommendations. Detects spoofable domains.
Output
Returns a JSON object containing the domain's MX record list, SPF record string and final policy, approximate SPF DNS lookup count, DMARC record with policy/subdomain policy/reporting address/percentage, MTA-STS boolean, TLS-RPT boolean, BIMI boolean, a numeric security score (0–100), and an array of human-readable warnings about spoofability or misconfiguration issues.
Example use cases
Pre-send domain spoofability check
“Before we launch this phishing simulation campaign, check whether acmecorp.com can actually be spoofed — I need to see its DMARC policy, SPF setup, and overall email security score.”
Customer domain onboarding audit
“We're onboarding newclient.io to our email platform — can you pull their full email security report including MX, SPF, DMARC, MTA-STS, and any warnings about gaps in their configuration?”
Competitor email security benchmarking
“I want to compare how our domain securityfirst.com stacks up on email security — run a full audit and give me the score plus any warnings about spoofing risks or missing records.”

Endpoint
POSThttps://api.vextorium.com/v1/email-security?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a comprehensive, multi-protocol email security audit covering SPF, DMARC, MX, MTA-STS, TLS-RPT, and BIMI in a single call, especially when spoofability detection and a composite score are needed. It is better than manual DNS lookups when you want interpreted policy analysis (e.g. detecting 'no all' in SPF or DMARC at p=none) with actionable warnings rather than raw DNS data.
Side effects
- Invalid or non-existent domain returns error or empty/null fields
- Domain with no DNS records may return null for all email security fields
- SPF lookup limit exceeded reported as a warning rather than hard error
- Typo in domain name leads to incorrect analysis with no indication of error
- Transient DNS resolution failures may produce incomplete results
