Php 如果Laravel Mail抛出的SwiftTransport异常不'；不要停止执行

我正在调查一个遗留的Laravel系统的问题，其中使用Mail:：send（）facade发送的电子邮件偶尔会在日志中记录错误，但实际上不会抛出错误；也就是说，这些错误并没有停止应用程序的执行

邮件设置为在呈现视图之前发送。有时会记录SwiftTransport_异常，并且邮件未收到；但视图仍然呈现

我无法重现这些错误，但关键是要处理这里抛出的任何错误。我希望捕获这些错误，以便存储电子邮件参数并在以后重新发送

Laravel版本是5.1（我知道…），服务器是WindowsServer12RT，PHP--V7.1.0NTSCGI

代码很简单，没有try/catch或抛出：

\Mail::send(
   $templateName,
   $paramsArray,
   function($message){
      $message->subject($subject);
      $message->to($userEmail, $userName);
   }
);

以下是其中一个错误的示例：

异常是否可以异步返回？如果是这种情况，是否可以在NTS系统上侦听它？

我已检查了此问题：。您可以使用Mail:：failures（）检查是否出现问题。请注意，如果无法访问电子邮件地址，则不视为“失败”。如果出现故障，您可能会在数据库中的某个地方标记为故障，并且可能需要重新发送。@RobBiermann谢谢，这可能会非常有用！是的，在这种情况下，我并不担心电子邮件是否会反弹。这是一个电子邮件验证的事情，所以反弹就像收据一样好。失败（）计数的持续时间是多少？这是按要求的吗，你知道吗？我找不到任何关于它的好文档。我不确定它的持久性。我认为它是基于请求的，因为这种逻辑通常存储在静态成员或单例中，在每个请求结束后重置。我是这么想的，但无法证实；）传奇，谢谢！我已检查此问题：。您可以使用Mail:：failures（）检查是否出现问题。请注意，如果无法访问电子邮件地址，则不视为“失败”。如果出现故障，您可能会在数据库中的某个地方标记为故障，并且可能需要重新发送。@RobBiermann谢谢，这可能会非常有用！是的，在这种情况下，我并不担心电子邮件是否会反弹。这是一个电子邮件验证的事情，所以反弹就像收据一样好。失败（）计数的持续时间是多少？这是按要求的吗，你知道吗？我找不到任何关于它的好文档。我不确定它的持久性。我认为它是基于请求的，因为这种逻辑通常存储在静态成员或单例中，在每个请求结束后重置。我是这么想的，但无法证实；）传奇，谢谢！
