--lang ->Use language for ISPConfig installation. Specify with --lang=en|de (only en (English) and de (German) supported currently).
--interactive ->Don\'t install ISPConfig in non-interactive mode. This is needed if you want to use expert mode, e. g. to install a slave server that shall be integrated into an existing multiserver setup.
--use-nginx ->Use nginx webserver instead of apache2
--use-amavis ->Use amavis instead of rspamd for mail filtering
--no-web ->Do not use ISPConfig on this server to manage webserver setting and don\'t install nginx/apache or pureftpd. This will also prevent installing an ISPConfig UI and implies --no-roundcube as well as --no-pma
--no-mail ->Do not use ISPConfig on this server to manage mailserver settings. This will install postfix for sending system mails, but not dovecot and not configure any settings for ISPConfig mail. It implies --no-mailman.
--no-dns ->Do not use ISPConfig on this server to manage DNS entries. Bind will be installed for local DNS caching / resolving only.
