【问题描述】：

我已经能够在 php 中使用 SMTP 发送电子邮件，但是当我尝试将内容类型更改为 html 时，电子邮件没有送达。这是我正在尝试使用的代码：

    require_once "Mail.php";

    $from = "FPM <[e-mail]>";
    $from_name = "FPM";

    $host = "localhost";
    $username = "username";
    $password = "password";

    $subject = "Subject";
    $message = "Message";

    $to = "<[e-mail]>";
    $headers = array ('From' => $from,
        'To' => $to,
        'Subject' => $subject,
        'MIME-Version' => '1.0',
        'Content-Type' => "text/html; charset=ISO-8859-1"
    );

    $smtp = Mail::factory('smtp',
        array ('host' => $host,
            'auth' => true,
            'username' => $username,
            'password' => $password));

    $mail = $smtp->send($to, $headers, $message);

如果我从标头中取出“Content-Type”参数，它会很好地发送消息。我不知道为什么添加它会导致问题。

【参考方案1】：

问题很可能出在 Mail 类上，但由于我们不知道您使用的是什么 Mail 类，所以很难回答。如果您还没有这样做，我真的会考虑使用 PHPMailer：https://github.com/PHPMailer/PHPMailer

【参考方案2】：

我做了一些研究，然后我编写了自己的代码来使用 SMTP 身份验证发送带有 HTML 格式的邮件。见这里：

<?php 
require_once "Mail.php";
$url = $_GET['baseUrl']; // source url
$success = false;
$senderName = isset( $_GET['txtname'] ) ? preg_replace( "/[^\.\-\' a-zA-Z0-9]/", "", $_GET['txtname'] ) : "";
$senderEmail = isset( $_GET['txtemail'] ) ? preg_replace( "/[^\.\-\_\@a-zA-Z0-9]/", "", $_GET['txtemail'] ) : "";
$msg = isset( $_GET['txtDesc'] ) ? preg_replace( "/(From:|To:|BCC:|CC:|Subject:|Content-Type:)/", "", $_GET['txtDesc'] ) : "";
$body = '<table  border="0">
  <tr>
    <th scope="col">Name:</th>
    <th scope="col">'.$senderName.'</th>
  </tr>
  <tr>
    <th scope="col">Company:</th>
    <td scope="col">'.$_GET['txtCompany'].'</td>
  </tr>
  <tr>
    <th scope="row">Phone:</th>
    <td>'.$_GET['txtphone'].'</td>
  </tr>
  <tr>
    <th scope="row">E-mail:</th>
    <td>'.$senderEmail.'</td>
  </tr>
  <tr>
    <th scope="row">URL:</th>
    <td>'.$url.'</td>
  </tr>
  <tr>
    <th scope="row">Massage:</th>
    <td>'.$msg.'</td>
  </tr>
</table>';

 $from = $senderName."<".$senderEmail.">";
 $to = "Contact ManagerHR<[e-mail]>";
 $subject = "Hi!";
 $host = "XXX.host.com";
 $username = "[e-mail]";
 $password = "*****";
 /* MIME-Version should be "1.0rn" and Content-Type should be "text/html; charset=ISO-8859-1rn" to send an HTML Email */
$headers = array ('MIME-Version' => '1.0rn',
        'Content-Type' => "text/html; charset=ISO-8859-1rn",
        'From' => $from,
        'To' => $to,
        'Subject' => $subject
     );
$smtp = Mail::factory('smtp',
   array ('host' => $host,
     'auth' => true,
     'username' => $username,
     'password' => $password));
$mail = $smtp->send($to, $headers, $body);
 if (PEAR::isError($mail)) 
   echo("<p>" . $mail->getMessage() . "</p>");
   else 
      header('Location: '.$url); // redirect to url where from inquiry made
   //echo("<p>Message successfully sent!</p>");
  
 ?>

【参考方案3】：

您应该通过 mime 对象创建邮件正文。梨会从那里处理它。 例如：

     $crlf = "\n";
    // Creating the Mime message
    $mime = new Mail_mime($crlf);

    // Setting the body of the email
    $mime->setTXTBody($text);
    $mime->setHTMLBody($html);
   ...
    $body = $mime->get();

【参考方案4】：

您可以分两步完成。

第 1 步：将代码放入文件中：

<?php
require 'PHPMailerAutoload.php';

$mail = new PHPMailer;

//$mail->SMTPDebug = 3;                               // Enable verbose debug output

$mail->isSMTP();                                      // Set mailer to use SMTP
$mail->Host = 'smtp.gmail.com';  // Specify main and backup SMTP servers
$mail->SMTPAuth = true;                               // Enable SMTP authentication
$mail->Username = '[e-mail]';                 // SMTP username
$mail->Password = 'secret';                           // SMTP password
$mail->SMTPSecure = 'tls';                            // Enable TLS encryption, `ssl` also accepted
$mail->Port = 587;                                    // TCP port to connect to

$mail->setFrom('[e-mail]', 'Mailer');
$mail->addAddress('[e-mail]', 'Joe User');     // Add a recipient
$mail->addAddress('[e-mail]');               // Name is optional
$mail->addReplyTo('[e-mail]', 'Information');
$mail->addCC('[e-mail]');
$mail->addBCC('[e-mail]');

$mail->addAttachment('/var/tmp/file.tar.gz');         // Add attachments
$mail->addAttachment('/tmp/image.jpg', 'new.jpg');    // Optional name
$mail->isHTML(true);                                  // Set email format to HTML

$mail->Subject = 'Here is the subject';
$mail->Body    = 'This is the HTML message body <b>in bold!</b>';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

if(!$mail->send()) 
    echo 'Message could not be sent.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
 else 
    echo 'Message has been sent';

步骤：2 在给定的 URL 中下载此包含的文件。 网址：https://github.com/PHPMailer/PHPMailer.git

然后点击克隆或下载按钮 并设置文件夹您的系统。

【参考方案5】：

使用 PHP 中的 SMTP 将您的 HTML 电子邮件发送到 2 或 3 封不同的电子邮件 工作 100%

<?php

require_once "Mail.php";

$host = "ssl://smtp.gmail.com";
$username = "[e-mail]";
$password = "password";
$port = "465";

$to  = '[e-mail]' . ', '; 
$to  = '[e-mail]' . ', '; 
$to  = '[e-mail]' . ', '; 

$email_from = "[e-mail]";
$email_subject = "Your Subject";

$email_body = "**<html> <body>**"; 
$email_body .= "<strong> Your HTML code </strong>";
$email_body .= "**</body></html>**";


$headers = array ('From' => $email_from, 'To' => $to, 'Subject' => 
$email_subject, 'Reply-To' => $email_address , 'MIME-Version' => '1.0', 'Content-Type' => "text/html; charset=ISO-8859-1");

$smtp = Mail::factory('smtp', array ('host' => $host, 'port' => $port, 'auth' => true, 'username' => $username, 'password' => $password));

$mail = $smtp->send($to, $headers, $email_body);

?>

【讨论】：

这如何回答有关Content-Type 的问题？此外，您应该使用.= 连接电子邮件地址。

【参考方案6】：

像这样在标题的第一行写内容类型

$to = "<[e-mail]>"; $headers = array ('Content-Type' => "text/html; charset=ISO-8859-1", 'From' => $from, 'To' => $to, 'Subject' => $subject, 'MIME-Version' => '1.0' ); 

这对我有用..
