我用一个简单的PHPMailer的形式，让我的网站的用户通过接触形式与我联系。我用我的谷歌Apps帐户发送邮件。在脚本中，我设定的用户提供了我的“从地址”的emailaccount。
直到几个星期前，这很顺利。从谷歌企业应用套件我可以点击回复发送到该用户联系我答复。
然而，最近，没有在我的代码进行任何更改，当我点击回复，我发邮件到自己。这是不是谷歌在它的政策变化？还是我也许做错了什么偶然？
这是输出我得到。我用[email protected]发送和使用[email protected]为客户账户。然而，当我打开我收到[email protected]并点击回复邮件，我发送电子邮件至[email protected]代替[email protected]的

谷歌不允许你从任意地址发送。您只能使用自己的帐户地址，或预定义的别名从您的Gmail设置。如果你尝试这样做，它会简单地从地址替换为您的帐户地址，因为你看到的。
一般试图做到这一点是错误的做法无论如何 - 它是伪造的，并会导致您的邮件是垃圾邮件过滤或退回由于SPF故障。做正确的方法是使用自己的地址作为发件人地址，并作为答复地址提交者的地址。 The contact form example provided with PHPMailer正是这样做的。那最重要的一点：
//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('[email protected]', 'First Last');
//Send the message to yourself, or whoever should receive contact for submissions
$mail->addAddress('[email protected]', 'John Doe');
//Put the submitter's address in a reply-to header
//This will fail if the address provided is invalid,
//in which case we should ignore the whole request
if ($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;
