php - 如何使用 PHPMailer 和 Google Apps 获得正确的“发件人”电子邮件地址？

Question

我使用一个简单的 PHPMailer 表单来允许我网站的用户通过联系表单与我联系。我使用我的谷歌应用程序帐户发送邮件。在脚本中，我将用户提供给我的电子邮件帐户设置为“发件人地址”。

直到几周前，这一切进展顺利。在 Google Apps 中，我可以单击回复以向与我联系的用户发送回复。

但是，最近，在我没有更改任何代码的情况下，当我点击回复时，我会向自己发送一封电子邮件。这是谷歌在其政策中改变的东西吗？还是我偶然做错了什么？

这是我得到的输出。我使用 [e-mail] 发送并使用 [e-mail] 作为客户帐户。但是，当我打开在 [e-mail] 中收到的邮件并单击回复时，我会向 [e-mail] 而不是 [e-mail] 发送电子邮件

Google 不允许您从任意地址发送。您只能使用您的帐户地址或 gmail 设置中的预定义别名。如果您尝试这样做，它会简单地将您的帐户地址替换为发件人地址，如您所见。

无论如何，通常尝试这样做是错误的方法 - 它是伪造的，并且会导致您的邮件被垃圾邮件过滤或由于 SPF 失败而被退回。正确的做法是使用您自己的地址作为发件人地址，并使用提交者的地址作为回复地址。PHPMailer 提供的联系表单示例正是这样做的。其中重要的一点：

    //Use a fixed address in your own domain as the from address
    //**DO NOT** use the submitter's address here as it will be forgery
    //and will cause your messages to fail SPF checks
    $mail->setFrom('[e-mail]', 'First Last');
    //Send the message to yourself, or whoever should receive contact for submissions
    $mail->addAddress('[e-mail]', 'John Doe');
    //Put the submitter's address in a reply-to header
    //This will fail if the address provided is invalid,
    //in which case we should ignore the whole request
    if ($mail->addReplyTo($_POST['email'], $_POST['name'])) {
        $mail->Subject = 'PHPMailer contact form';
        //Keep it simple - don't use HTML
        $mail->isHTML(false);
        //Build a simple message body
        $mail->Body = <<<EOT
Email: {$_POST['email']}
Name: {$_POST['name']}
Message: {$_POST['message']}
EOT;
