If you want to use another folder for the vmail-volume, you can create a `docker-compose.override.yml` file and add the following content:

```
version: '2.1'
volumes:
  vmail-vol-1:
    driver_opts:
      type: none
      device: /data/mailcow/vmail	
      o: bind
```

### Moving an existing vmail folder:

- Locate the current vmail folder by its "Mountpoint" attribute: `docker volume inspect mailcowdockerized_vmail-vol-1`

``` hl_lines="10"
[
    {
        "CreatedAt": "2019-06-16T22:08:34+02:00",
        "Driver": "local",
        "Labels": {
            "com.docker.compose.project": "mailcowdockerized",
            "com.docker.compose.version": "1.23.2",
            "com.docker.compose.volume": "vmail-vol-1"
        },
        "Mountpoint": "/var/lib/docker/volumes/mailcowdockerized_vmail-vol-1/_data",
        "Name": "mailcowdockerized_vmail-vol-1",
        "Options": null,
        "Scope": "local"
    }
]
```

- Copy the content of the `Mountpoint` folder to the new location (e.g. `/data/mailcow/vmail`) using `cp -a`, `rsync -a` or a similar non strcuture breaking copy command
- Stop mailcow by executing `docker-compose down` from within your mailcow root folder (e.g. `/opt/mailcow-dockerized`)
- Create the file `docker-compose.override.yml`, edit the device path accordingly
- Delete the current vmail folder: `docker volume rm mailcowdockerized_vmail-vol-1`
- Start mailcow by executing `docker-compose up -d` from within your mailcow root folder (e.g. `/opt/mailcow-dockerized`)
