Question

以下代码段返回电子邮件已发送，并且确实将其发送到域@ qub.ac.uk上的任何电子邮件地址，但是不适用于任何其他电子邮件域（即@homail）。 com/@gmail.com等）。有没有人遇到过类似的问题？

<?php
include '../dbConnection.php';

$email = "";
$email_err = "";

if ($_SERVER["REQUEST_METHOD"] == "POST") {

    // Validate email
    if (empty(trim($_POST["email"]))) {
        $email_err = "Please enter an email address.";
    } elseif (!filter_var(trim($_POST["email"]), FILTER_VALIDATE_EMAIL)) {
        $email_err = "Invalid email format";
    } else {
        $email = $_POST["email"];
        $to = "$email";
        $subject = 'Added to system';
        $header = 'From: example@hotmail.com' . "\r\n" .
                'Reply-To: example@hotmail.com' . "\r\n" .
                'X-Mailer: PHP/' . phpversion();
        $message = 'You have been added to the system';
        if (mail($to, $subject, $message, $header)) {
            echo "Email Sent";
        } else {
            echo "Failure";
        }
    }
}
?>
