TECHKEE DOMAIN ASSURANCE

Choose what to assess All 8 checks selected

Keep everything selected for a full assessment, or choose the checks you need. Domain registration is informational and does not affect the security grade.

SMTP STARTTLS uses an MX lookup to find mail servers, even when the MX assessment is not selected.

Starting the assessment…This normally takes less than a minute.

A point-in-time report

This assessment uses public DNS records and externally observable mail-server behaviour at the time shown above. Configurations can change later. A result marked “not verified” is not treated as a confirmed failure.

What we check

Mail routing, SPF, DMARC, discoverable DKIM keys, MTA-STS, TLS-RPT and live STARTTLS behaviour across receiving mail servers.

How it works

We read the domain’s public records, retrieve its published transport policy and safely connect to a limited number of public MX hosts.

Why it matters

These controls help prevent impersonation, make legitimate email easier to trust and protect messages while mail servers exchange them.
