About TestMail
TestMail by TehnoGuru provides a public-record domain check and an optional live-email test. Managed monitoring is separate and is not accepting requests yet.
What the checker covers
The checker reviews public SPF, DMARC, MX, MTA-STS, and TLS-RPT evidence. The optional live test adds receipt and DKIM evidence from one message sent from the checked domain.
- The generated live-test address accepts one small, attachment-free message during its 30-minute lifetime
- DKIM cannot be fully assessed from a domain alone when selectors or signed-message evidence are unavailable
- DNS timeouts and unavailable hosted policies remain inconclusive rather than being treated as passes
How monitoring works
Managed monitoring begins only after an operator reviews the request and you approve a written scope and quote. Approved users then receive invite-only portal access to the checks, alerts, and reports included in that scope.
Who it is for
TestMail is built for business domain owners, IT administrators, security or operations teams, and service providers responsible for real mail domains.
