Configuration for Modoboa mail system (https://modoboa.org/)

Modoboa is a solution to quickly deploy and manage a complete email server, compatible with latest standards and optimized for delivery and reputation protection.

At least, you need to setup in config.inc.php, the following:

$rcmail_config['vacation_driver'] = 'modoboa';
$rcmail_config['vacation_log'] = false;
$rcmail_config['token_api_modoboa'] = '';
