it depends on how you installed zammad.

If for example if zammad can be started with `systemctl start zammad`  
You’ll want to look at `/etc/systemd/system/zammad.service` or if that doesn’t exist `/lib/systemd/system/zammad.service`

Then see if there’s a line like

`EnvironmentFile=-/etc/default/zammad`

Then you would put  
`APP_RESTART_CMD="systemctl restart zammad"` # or however you want to restart zammad  
in `/etc/default/zammad`

If that line doesn’t exist you could add the full `EnvironmentFile` line under `[service]` and create the `/etc/default/zammad` file or do whatever other way systemctl has provided to set environment variables.

I haven’t tested any of this, but if systemctl is how you start zammad, then that is where you set the environment variables.
