下面是发送到 sendgrid 的标头和原始数据。我已经添加了发送出去的原始数据。请注意，第一个原始数据正在成功发送。当我将此数据发送到 sendgrid 时，它成功地将电子邮件发送出去。它不做的是隐藏电子邮件。因此收件人可以在该部分中看到其他人的电子邮件地址to。这是一个安全风险。

第二次尝试
在这次尝试中，我to从消息中删除了参数并将其添加到标题中，结果如下所示。请注意，这根本不起作用并引发异常。我将尝试捕获异常并将其发布。

更新的代码
下面是我提供的代码...注意，提供的代码按提供的顺序处理代码。
实现的代码（这是在 cron 工作中）
$controller =& new Controller();
$email =& new SendgridComponent(null);
$email->initialize($controller);
$email->from = "support@workworktest.com";
$email->template = "newest_open";
$email->sendAs = 'html';
$email -> delivery = 'sendgrid';
$controller->set('tableData',$tableData);
$userEmails = array();
$smtpapi = array();
foreach($users as $user) {
$smtpapi[] = $user['User']['email'];
}
$email->to = 'number@amail.com';
$email->smtpapi = $smtpapi;
$email->subject = 'Todays Newest Open Projects';
$return = $email->send();
发送网格组件
在以下代码中，我更改了设置收件人电子邮件的方法中的To参数。_sendgrid()有人告诉我这个参数可以是任何电子邮件，sendgrid 会忽略它并寻找它，X-SMTPAPI如果它提供了。但相反，X-SMTPAPI参数被忽略了。http://www.opensource.org/licenses/mit-license.php MIT 许可证 */ App::import('Component', 'Email');
