如何在CakePHP中获得退回电子邮件？

Question

我正在使用cakePHP 2.0发送电子邮件。一切正常，但是如何捕获退回的电子邮件？我已经添加了ReplyTo并返回，但仍然没有收到退回的电子邮件。

$this->Email->sendAs = 'both';
$this->Email->from = 'abc@xyz.com';
$this->Email->to = 'wrong@wrong.com';
$this->Email->replyTo = 'abc@xyz.com';
$this->Email->return = 'abc@xyz.com';
$this->Email->headers = ['Return-Path'=>'abc@xyz.com'];
$this->Email->subject = 'Test Eail';
$msg = 'Message';
$this->Email->send($msg);
