我已经使用mailfunction创建了一个contactform。但是所有的邮件都是垃圾邮件。我的代码如下

<?php 

//  MAIL SEND PHP

if(isset($_POST['submit'])){
    $to = "abc@gmail.com"; // this is your Email address
    $from = $_POST['email']; // this is the sender's Email address
    $email = $_POST['mail'];
    $name = $_POST['name'];
    $subject = "Form submission";
    $subject2 = "Copy of your form submission";
    $message = $email . " " . $name . " wrote the following:" . "\n\n" . $_POST['message'];
    $message2 = "Here is a copy of your message " . $name . "\n\n" . $_POST['message'];

    $headers = "From:" . $from;
    $headers2 = "From:" . $to;
    mail($to,$subject,$message,$headers);
    mail($from,$subject2,$message2,$headers2); // sends a copy of the message to the sender
    echo "Mail Sent. Thank you " . $first_name . ", we will contact you shortly.";
    // You can also use header('Location: thank_you.php'); to redirect to another page.
    }

    // END MAIL SEND PHP
?>

正如我之前遇到的这个问题一样，您可以使用phpmailer解决这个问题。有了smtp的详细信息，希望它能正常工作。

垃圾邮件与您所实现的代码无关。由于您发送电子邮件的域，他们将发送垃圾邮件。您是否为您的电子邮件域设置了SPF\DKIM？电子邮件的可交付性可能与您发送电子邮件所使用的代码无关，更可能与您发送的内容或从何处发送电子邮件有关。这似乎更像是服务器配置上的一个问题。您应该查看PTR和SPF记录
