Problems with an HTML form

[APC]

Hi, I am using the following form on my website to allow the users to send an email directly to my account. The PHP code seems fine to me, yet it isn't working. When I press send I am being taken to that page called "thankhyou.html" which implies to me that the email has been sent, yet I am not receiving any emails. I have tried using a different email address, yet this makes no difference. I have also tried hosting the pages on another server WHICH I KNOW FOR SURE IS COMPATIBLE WITH THE LATEST PHP. Still I have had no luck. Does anyone have any ideas? 

<form action="mail.php" method="POST">

<table>

<tr><td>Name: </td><td><input type="text" name="name"></td></tr>

<tr><td>Email: </td><td><input type="text" name="email"></td></tr>

<tr><td>Subject: </td><td><input type="text" name="subject"></td></tr>

<td>Message: </td><td><textarea style="width: 200px; height: 90px; " name="message"></textarea></td>

<td colspan="2"><input type="submit" value="Send"></td>

<td colspan="2"><input type="reset" value="Reset"></td></tr>

</table>

</form>

 

<?php

 

if(isset($_POST['name'])) {

 

$name = $_POST['name'] . "\n";

$email = $_POST['email'] . "\n";

$subject = $_POST['subject'] . "\n";

$messageorig = $_POST['message'] . "\n";

 

$message = "Name: $name " . "\n";

$message .= "Email: $email " . "\n";

$message .= "Message: $messageorig " . "\n";

 

if(mail("root@heathfieldresidentialhome.co.uk", $subject, $message, "From: Contact Form")) {

        header("Location: thankyou.html");

} else {

        echo "Mail sending failed";

}

 

}

?>

if (mail()) isn't an accurate representation of whether or not the email actually went through, it just returns the success of the function call.  There's no easy way to test that an email went through in PHP. >_>

is the host allowing out going mail?? not all do, if there not free.

Yes, it's a paid host which allows this function.
