通过api发布回复而不发送电子邮件

Question

您好，我使用osticket进行票务系统，我使用API​​创建票证，当我在代理面板中登录并更新票证状态并选择罐头响应电子邮件时，但是当我尝试使用API​​电子邮件更新satatus时，状态正在更改，响应已保存，但电子邮件没有发送，这是我的帖子回复方法

$data = array(
            'ticketNumber' =>34343,     
            'msgId' => 'true',   
            'a'      =>  'reply',  
            'emailreply'     => '1', 
            'emailcollab'   =>  1,
            'cannedResp'    =>  3,
            'draft_id'  =>      '',
            'response'  =>      'Hi,The Testing has been Completed of your Reported Task Ticket From Live',
            'signature'   =>  'none',  
            'reply_status_id'   => 3,  
            'staffUserName'        => 'fahim', 
            'ip_address'   =>      192.185.57.132, 
            'cannedattachments' => ''
        );

        function_exists('curl_version') or die('CURL support required');
        function_exists('json_encode') or die('JSON support required');
        set_time_limit(300);
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $config['url']);
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
        curl_setopt($ch, CURLOPT_USERAGENT, 'osTicket API Client v1.8');
        curl_setopt($ch, CURLOPT_HEADER, FALSE);
        curl_setopt($ch, CURLOPT_HTTPHEADER, array( 'Expect:', 'X-API-Key: '.$config['key']));
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, FALSE);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
        $result_ost=curl_exec($ch);
        print_r($result_ost);

        if(curl_errno($ch)){
            echo 'Request Error:' . curl_error($ch);
        }
