Adds zerosmtp-check under SMTP Testing.

It checks whether outbound SMTP works from the machine it runs on: TCP reachability, STARTTLS and implicit TLS, and whether AUTH is offered - against any host and port, not only our own. npx zerosmtp-check, no install, --json for monitoring.

MIT, Node.js, published to npm with provenance. Disclosure: I maintain it.
