## Common questions

### Which Docker image should a self-hoster use for the free version of Poste?

The free version uses the public analogic/poste.io image. The Pro version uses a private repository image and requires a repository login.

### Which host path should be mounted as the Poste data directory?

Mount a host data directory to /data inside the container, such as /your-data-dir/data:/data. Free and Pro use the same data directory structure.

### How can I follow container logs after startup?

Use docker logs -f mailserver after starting the container. This follows the log output using the container name from the getting-started example.
