php - 没有收到来自 PHP mail() 方法的电子邮件

Question

我试图设置一个 email.html 和一个 action.php，以便有人可以从网站发送电子邮件。这是 email.html 中的代码

<form action="./action.php" method="post">
    <p>Your Name</p>
    <p><input type="text" name="name" /></p>
    <p>Email</p>
    <p><input type="text" name="email" /></p>
    <p>Services</p>
    <p><input type="text" name="service" /></p>
    <p>Requests</p>
    <p><textarea rows="8" cols="32" name="comment"></textarea></p>
    <p><input type="submit" value="Send" /></p>
</form>

在 action.php 我有

<?php
    $to = "foo@outlook.com";
    $subject = "Test mail";
    $message = "Hello! This is a simple email message.";
    $from = "foo2@gmail.com";
    $headers = "From:" . $from;
    mail($to,$subject,$message,$headers);
    echo "Mail Sent.";
?>

在 email.html 中输入的信息成功加载到 action.php 中，但我的 Outlook 收件箱中没有收到任何来自电子邮件方法的信息。我错过了什么吗？

首先检查 mail 的返回值，看看邮件是否被您的 SMTP 服务器接受。

此外，根据 Namecheap 的文档，your From address is invalid .

Only domains that are hosted on our servers can be used in 'From' field. Any domain that is not hosted with us cannot be added to 'From' field. We had to take this measure to prevent sending spam using forums, guest books and contact forms scripts. For your site scripts to work properly you should set 'From' field to email account that has been created in your cPanel.

即使您的托管公司允许这样做，您也不应该使用非 Gmail 服务器从 @gmail.com 发送邮件。它通常是 blocked by SPF以及接收端的其他此类反垃圾邮件措施。
