Question

以下是构建/发送电子邮件的脚本：

$boundary = md5(date('U'));

$to = $email;
$subject = "My Subject";

$headers = "From: myaddress@mydomain.com" . "\r\n".
           "X-Mailer: PHP/".phpversion() ."\r\n".
           "MIME-Version: 1.0" . "\r\n".
           "Content-Type: multipart/alternative; boundary=--$boundary". "\r\n".
           "Content-Transfer-Encoding: 7bit". "\r\n";

$text = "You really ought remember the birthdays";     
$html = '<html>
    <head>
      <title>Birthday Reminders for August</title>
    </head>
    <body>
      <p>Here are the birthdays upcoming in August!</p>
      <table>
        <tr>
          <th>Person</th><th>Day</th><th>Month</th><th>Year</th>
        </tr>
        <tr>
          <td>Joe</td><td>3rd</td><td>August</td><td>1970</td>
        </tr>
        <tr>
          <td>Sally</td><td>17th</td><td>August</td><td>1973</td>
        </tr>
      </table>
    </body>
    </html>
    ';

$message = "Multipart Message coming up" . "\r\n\r\n".
       "--".$boundary.
       "Content-Type: text/plain; charset=\"iso-8859-1\"" .
       "Content-Transfer-Encoding: 7bit".
       $text. 
       "--".$boundary. 
       "Content-Type: text/html; charset=\"iso-8859-1\"". 
       "Content-Transfer-Encoding: 7bit". 
       $html.
       "--".$boundary."--";



mail("toAddress@example.com", $subject, $message, $headers);

它发送消息就好了，我的收件人收到了消息，但是他们用text / plain而不是multipart / alternative来获取整个消息。查看收到的消息的来源给出了这一点（删除了许多内容）：

看起来内容类型标题在从multipart / alternative到text / plain的过程中发生了变化。我不是系统管理员，所以如果这是一个sendmail问题，我就在我头脑中。有什么建议吗？

Answer 1

该行

"Content-Type: multipart/alternative; boundary=--$boundary". "\r\n".

应该是

"Content-Type: multipart/alternative; boundary=$boundary". "\r\n".

您不在标题中包含短划线。

Answer 2

为了让我能够正常使用，我还需要在每个标题行的末尾添加一个“\ r \ n”，其中两个（“\ r \ n \ r \ n”）结尾处文本和html主体之前的行，以及每个主体末尾的行。这导致如下：

$message = "Multipart Message coming up" . "\r\n\r\n".
       "--".$boundary."\r\n".
       "Content-Type: text/plain; charset=\"iso-8859-1\""."\r\n".
       "Content-Transfer-Encoding: 7bit"."\r\n".
       $text."\r\n". 
       "--".$boundary."\r\n". 
       "Content-Type: text/html; charset=\"iso-8859-1\""."\r\n". 
       "Content-Transfer-Encoding: 7bit"."\r\n".
       $html."\r\n".
       "--".$boundary."--";

Answer 3

使用“\ n”而不是“\ r \ n”看起来qmail与“\ r”有问题

Answer 4

只是一个想法，但使用phpmailer或Zend_Mail这样的内容可能会更容易。
