## Overview

Test-SMTP is a self-contained SMTP diagnostic that accepts interactive or command-line settings, connects to a chosen server, checks TLS and optional authentication, and can submit a test message. The source excerpt shows configuration resolution and SMTP operations; some intervening code is omitted, so the internal orchestration is represented at a coarse level.

Main entry points: [`Test-SMTP.py`](https://github.com/asheroto/test-smtp/blob/main/Test-SMTP.py) (SMTP connection test)
