我正在使用PHP Mail功能发送邮件
我只需要找到邮件的状态，无论是发送还是退回
有没有办法解决这个问题
答案 0 :(得分：2)
您可以将return-path标头与特定的电子邮件地址一起使用 - 例如bounce@domain.com 之后，所有退回（未交付）的电子邮件将返回收件箱以获取bounce@domain.com
您可以通过PHP连接到此pop3收件箱并阅读所有邮件。 解析每条消息并找到（可能是通过正则表达式）错误代码和原因...
我使用此代码：
$bounce = new BounceMail();
$bounce->setDebug(false);
//create connection
$bounce->createConnection('server', 110, 'user', 'password');
//parse messages
$bounce->parseMessages();
//save parsed messages to database
$messages = $bounce->getParsedMessages();
foreach ($messages as $message_id => $message) {
/* variable $message looks like:
$message = array(
'email_address' => 'email',
'bounce_type' => 'bounce type',
'smtp_server' => 'smtp_server',
'smtp_error' => 'smtp_error',
);
*/
//save returned email to database here
}
和BounceMail类：

你应该在parseSMTPError中添加更多的常规
