Howto: Add Plugins To Roundcube Webmail

1. Uncomment the build args section of the web service definition in docker-compose.yml:

    web:
      image: jeboehm/mailserver-web:latest
      build:
      context: ./web
      args:
        RCPLUGINS: kitist/html5_notifier johndoh/contextmenu
   

2. Change the RCPLUGINS declaration and add the wanted packages. You can find them on roundcube.net.
3. If your plugin requires additional configuration, change the configuration file in web/rootfs/var/www/webmail/config/config.inc.php.
4. Rebuild the image by running bin/production.sh build web.
5. Recreate the container: bin/production.sh up -d web.
