代码总是转到else循环并发送错误消息。 代码错了吗？

<?php
 if(isset($_POST['submit']))
 {
    $name = $_POST['name'];
    $email = $_POST['email'];
    $query = $_POST['message'];
    $email_from = $name.'<'.$email.'>';

    $to="someone@gmail.com";
    $subject="Enquiry!";
    $headers .= "From: ".$email_from."
";
    $headers  = 'MIME-Version: 1.0' . "
";
    $headers .= 'Content-type: text/html; charset=iso-8859-1' . "
".PHP_EOL;
    $message="mail sent";


    if(mail($to,$subject,$message,$headers))
    {
        header("Location:../contact.php?msg=Successful Submission! Thankyou for contacting us.");
    }
    else
    {
        header("Location:../contact.php?msg=Error To send Email !");
    }
}
?>
