The Ping comment claimed the self-test could not produce a false negative and left the impression it therefore proved deliverability. It does not, and the distinction is the whole trap: a relay that gates sender identity at end-of-DATA gates it on the way OUT. Fastmail answers 250 for [email protected] addressed to the account's own mailbox and 551 5.7.1 "Not authorised to send from this header address" for that same From addressed to anyone else — and only the account's exact authorized identity passes the second one, another local-part on the same domain is refused too. So a green Ping means connect, TLS, AUTH and message shape are good, and nothing more; the operator still has to have authorized From as a sending identity with their provider, and the first real OTP is what proves they did. Addressing the self-test somewhere external would not fix it either — the only mailbox an operator can reliably check is usually inside the same account — so the honest move is to scope the claim rather than buy false confidence with a bigger probe.

Table of Contents
Features
- Wake on Join: Servers start automatically when a player connects, and stop when idle — like hibernate for your server.
- Web Dashboard: Monitor server status, online players, and resource usage from your browser, with backup and restore management.
- Auto Backup & Restore: Scheduled world backups with one-click rollback from any backup point.
- World Reaper: Worlds idle for more than 15 days are automatically backed up and removed to free disk space.
- Multi-core Support: Compatible with Paper, Fabric, Forge, and NeoForge, federated behind a Velocity proxy.
- Modpack Submission: Players submit custom modpacks; admin approval triggers automatic build and deployment.
- Passkey Login: Passwordless authentication via fingerprint, face recognition, or hardware security keys.
- Zero Trust Security: Panel traffic protected by Cloudflare Access; the internal API is never exposed to the internet.
Getting Started
On a prepared Linux host, run:
curl -fsSL https://raw.githubusercontent.com/MliroLirrorsIngenuity/Felis/main/deploy/bootstrap.sh | sudo bash
The script installs K3s, deploys the control plane, and launches a setup wizard. Once done, open your browser at the configured domain.
