Yii2 如何处理 Swift_TransportException 异常？

Question

尝试使用 swiftmailer 发送邮件时，出现以下错误：

Expected response code 250 but got code "550", with message "550 User test@test.com has exceeded its 24-hour sending limit. Messages to 250 recipients out of 250 allowed have been sent. Relay quota will reset in 1.47 hours.

我已将 swiftmailer 放在 try catch 块中，如下所示：

public function sendMail($emailTemplateName, $subject, $body, $fromEmail, $toEmail)
{
        try
        {
            return Yii::$app->mailer->compose(['html' => $emailTemplateName], ['emailBody' => $body])
                ->setFrom([ $fromEmail => Yii::$app->params['siteTitle'] ])
                ->setTo($toEmail)
                ->setSubject($subject)
                ->send();
        }
        catch(Swift_SwiftException $exception)
        {
            return 'Can sent mail due to the following exception'.print_r($exception);
        }
}

我也尝试过Swift_SwiftException，Exception但没有被抓住。

我该如何处理这个异常？

好的，我知道了。我需要\Swift_TransportException在捕获中使用。
