Editorial interest 78/100 Selection signal · not a rating of the site

A focused toolkit for checking DNS, email authentication, SMTP availability, TLS, and certificate health.

Landing page captured for the 2026-09-07 issue.

Field notes

The site separates one-time diagnostics from ongoing monitoring. Its listed checks cover SPF and DMARC spoofing protection, MX and SMTP availability, STARTTLS, MTA-STS, TLS reporting, DNSSEC, and certificate validity. The homepage says public SMTP tests stop before DATA, avoiding changes to domain configuration, while an example event records SMTP becoming unavailable and recovering on a later scheduled check.
