Question

我搜索了很多，但找不到任何解决方案。在我的代码更改几个小时后，我尝试了从php.net的例子，它的行为相同。

如果我将它发送到我的Gmail地址，一切都很好，如果我将它发送到另一台服务器，它不会将其呈现为HTML。我尝试了大约8台服务器，其中4台遇到了这个问题

这是代码（php示例）：

// subject
$subject = 'Birthday Reminders for August';

// message
$message = '
<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>
';

// To send HTML mail, the Content-type header must be set
$headers  = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";

// Additional headers
$headers .= 'To: Mary <mary@example.com>, Kelly <kelly@example.com>' . "\r\n";
$headers .= 'From: Birthday Reminder <birthday@example.com>' . "\r\n";
$headers .= 'Cc: birthdayarchive@example.com' . "\r\n";
$headers .= 'Bcc: birthdaycheck@example.com' . "\r\n";

// Mail it
mail($to, $subject, $message, $headers);
?>

这是来自gmail的“show original”（gmail只是客户端，邮件来自php服务器），消息未正确显示 - html是raw：

伊万的评论是正确的！

尝试以下使用phpmailer lib的示例。

<?php
//phpmailer lib
require_once 'class.phpmailer.php';

$mail = new PHPMailer(true); 

try {
    $mail->AddAddress('mary@example.com', 'Mary');
    $mail->AddAddress('kelly@example.com', 'Kelly');
    $mail->SetFrom('birthday@example.com', 'Birthday Reminder');
    $mail->AddReplyTo('no-reply@example.com', 'No-reply');
    $mail->Subject = 'Birthday Reminders for August';
    $mail->AltBody = 'Here are the birthdays upcoming in August!\nPerson:Joe BirthDay:3rd Aug 1970\nPerson:Sally BirthDay:17th Aug 1973\n'; 
    $mail->MsgHTML('
        <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>'
    );

    $mail->Send();

    echo "Message Sent OK<p></p>\n";
} catch (phpmailerException $e) {
    echo $e->errorMessage(); 
} catch (Exception $e) {
    echo $e->getMessage(); 
}
?>

这取决于将显示消息的电子邮件阅读器。

Gmail和大多数现代电子邮件客户端（如MS Outlook，Thunderbird，Evolution ...）将呈现html，如果它有html内容，一些较旧的读者会将其呈现为纯文本，因为它们无法呈现html（如松鼠或部落）。

为了在任何读者中正确呈现电子邮件，您必须在电子邮件正文中放入纯文本和html版本的电子邮件。

最好的方法是在php 中使用 PHPmailer，SwiftMail和其他包装器进行电子邮件，但如果你真的希望自己做try this。

另外，请注意，有些读者在显示各种html元素（如div和css规则）时会遇到问题。 最好坚持使用标签和css MS Outlook可以呈现的内容。

尝试设置MIME边界

// generate a random string to be used as the boundary marker
       $mime_boundary="==Multipart_Boundary_x".md5(mt_rand())."x";

       // now we'll build the message headers
       $headers = "From: $from\r\n" .
       "MIME-Version: 1.0\r\n" .
          "Content-Type: multipart/mixed;\r\n" .
          " boundary=\"{$mime_boundary}\"";

       // here, we'll start the message body.
       // this is the text that will be displayed
       // in the e-mail
       $message="This is an example";

       // next, we'll build the invisible portion of the message body
       // note that we insert two dashes in front of the MIME boundary 
       // when we use it
       $message = "This is a multi-part message in MIME format.\n\n" .
          "--{$mime_boundary}\n" .
          "Content-Type: text/plain; charset=\"iso-8859-1\"\n" .
          "Content-Transfer-Encoding: 7bit\n\n" .
       $message . "\n\n";

PHP使用mail（）发送html - 某些服务器以文本形式接收
