How to self-host Simple NixOS Mailserver

Simple NixOS Mailserver runs on Nix. The project's own install guide is the place to start; most people put it on a small server with Docker and a reverse proxy for HTTPS.

Get a server: a home server, a VPS, or a managed app host.
Install it the way the project's docs describe, usually with Docker Compose.
Put it behind HTTPS and set up backups before you add real data.
Update it regularly. Watch the project's releases.
