How to self-host SOGo
SOGo runs on Objective-C. 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.
