如果在通过PHP函数mail（）发送电子邮件时它被退回，我想保存电子邮件吗？什么是捕获它的最佳方式？

Answer 1

首先，您需要使用mail（）函数发送电子邮件，并使用其他标头。您将返回电子邮件地址指向邮箱，您将收集退回的电子邮件。下面的代码是如何实现它的一个例子。

$recipient = "jack@someotherexample.com";
$subject = "test subject";
$message = "test message";

$body = "<html>\r\n";
$body .= "<body style=\"font-family:Verdana, Verdana, Geneva, sans-serif; font-size:12px; color:#666666;\">\r\n";
$body .= $message;
$body .= "</body>\r\n";
$body .= "</html>\r\n";

$headers  = "From: My site<noreply@example.com>\r\n";
$headers .= "Reply-To: bounce@example.com\r\n";
$headers .= "Return-Path: bounce@example.com\r\n";
$headers .= "X-Mailer: PHP\r\n";
$headers .= 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";

$result = mail($recipient, $subject, $body, $headers); 

if($result)
{
    echo "email sent";
}
else
{
    echo "email send error";
}

您只需在收件箱中查看退回的错误电子邮件即可。下面的示例代码将连接到imap收件箱，获取并打印出它在那里找到的所有电子邮件。您可以根据需要轻松定制。

/* connect to server */
$hostname = '{example.com:143}INBOX';
$username = 'bounce@example.com';
$password = 'password';

/* try to connect */
$inbox = imap_open($hostname,$username,$password) or die('Cannot connect to mailbox: ' . imap_last_error());

/* grab emails */
$emails = imap_search($inbox,'ALL');


/* if emails are returned, cycle through each... */
if($emails) {

  /* begin output var */
  $output = '';

  /* put the newest emails on top */
  rsort($emails);

  /* for every email... */
  foreach($emails as $email_number) {

    /* get information specific to this email */
    $overview = imap_fetch_overview($inbox,$email_number,0);
    $message = imap_fetchbody($inbox,$email_number,1.2);

    /* output the email header information */
    $output.= '<div '.($overview[0]->seen ? 'read' : 'unread').'">';
    $output.= '<span>'.$overview[0]->subject.'</span> ';
    $output.= '<span>'.$overview[0]->from.'</span>';
    $output.= '<span>'.$overview[0]->date.'</span>';
    $output.= '</div>';

    /* output the email body */
    $output.= '<div class="body">'.$message.'</div>';
  }

  echo $output;
}

/* close the connection */
imap_close($inbox);

向电子邮件标题添加退回电子邮件地址，并监控来自PHP的该电子邮件帐户以进行退回。
