# Diagnose Email

`POST /api/monitoring/diagnose-email`

Probe the email path from inside this container and explain the result.

Answers the question a failed test alert leaves open: is the mail server

per-port TCP reachability plus a full authenticated handshake (EHLO,
STARTTLS, login, NOOP) against the configured port, sending no message.
