What it does
intoDNS checks domain DNS and mail-server configuration and provides reports with suggestions linked to protocol documentation.
Use intoDNS for a configuration overview before narrowing a problem to one record. Its stated output combines DNS and mail-server reports, with protocol references that help explain why a setting was flagged. The report is a diagnostic starting point; changes should be chosen for the domain's intended setup rather than applied blindly from a warning label.
