Mailbox register

Good afternoon! I'm trying to register a mail box in ISPConfig, but I get the following error when I add:
Code:

Code:

public function addMailBox(Server_Account $a, $new) {
        //print_r($params);
        $client     = $a->getClient();

        $params = array(
            'server_id' => 1,
            'email' => '[email protected]',
            'login' => '[email protected]',
            'password' => 'qwer1234',
            'name' => $new['name'],
            'uid' => 5000,
            'gid' => 5000,
            'maildir' => '/var/vmail/test.int/joe',
            'quota' => 0,
            'cc' => '',
            'homedir' => '/var/vmail',
            'autoresponder' => 'n',
            'autoresponder_start_date' => array('day' => 1,'month' => 7, 'year' => 2012, 'hour' => 0, 'minute' => 0),
            'autoresponder_end_date' => array('day' => 20,'month' => 7, 'year' => 2012, 'hour' => 0, 'minute' => 0),
            'autoresponder_text' => 'hallo',
            'move_junk' => 'n',
            'custom_mailfilter' => 'spam',
            'postfix' => 'n',
            'access' => 'n',
            'disableimap' => 'n',
            'disablepop3' => 'n',
            'disabledeliver' => 'n',
            'disablesmtp' => 'n'
            );

        $action = 'mail_user_add';
        $result = $this->_request($action, $params);
        return $result;
    }

Error:

Code:

{"result":null,"error":{"message":"email_error_isemail<br \/>\r\nlogin_error_regex<br \/>\r\nquota_error_value<br \/>\r\n","code":9999}}

If anyone can help, I appreciate it!!
