How this service works
SYNTHORA mtasts: sMTP transport-security audit: MTA-STS (RFC 8461) + TLS-RPT (RFC 8460). Resolves the policy DNS records, fetches and parses the well-known policy file, cross-validates the policy mx: patterns against the domain's real MX, and returns an enforce/report verdict. Complements SPF/DKIM/DMARC auditing with the TLS transport layer. Deterministic, Ed25519-signed. SYNTHORA.
Output
Returns a JSON object with an overall compliance score (0–100), the domain audited, a list of issues found, the full MTA-STS policy (MX hosts, enforcement mode, max_age, DNS presence, MX-to-DNS match, policy reachability), TLS-RPT presence status, and a human-readable verdict string (e.g. 'enforced+reporting').
Example use cases
Pre-send email security check
“Before we start the campaign, run a full MTA-STS and TLS-RPT audit on acmecorp.com — I need to know if our email transport security is properly enforced and whether TLS reporting is configured.”
Compliance audit for client domain
“Audit clientdomain.org for MTA-STS compliance — I want to see the enforcement mode, whether the policy file is reachable, if the MX records match, and get an overall score.”
TLS-RPT-only check
“Just check whether tls-rpt is present on mybusiness.io — run only the tlsrpt audit and tell me if TLS reporting is configured for that domain.”
Technical details
Endpoint
POSThttps://api.hergertsynthora.com/v1/mtastsWhen to prefer
Use this endpoint when you need to programmatically audit a domain's MTA-STS and TLS-RPT configuration, especially when you want a structured score, machine-readable policy details, and a verdict — rather than manually inspecting DNS records. Prefer this over generic DNS lookup tools when you specifically need MTA-STS policy reachability checks and MX validation in a single scored call.
Side effects
- Domain does not exist or is unreachable — policy_reachable: false, DNS flags set to false
- MTA-STS DNS record missing — dns_present: false with issues listed
- MX records do not match MTA-STS policy — mx_matches_dns: false
- TLS-RPT record absent — tls_rpt.present: false
- Invalid input domain format — likely 400 or ok:false response
- Policy file not reachable over HTTPS — policy_reachable: false
