php form mail not working

[Deej]

Hi, I can't seem to get php form mail to work. I've tried the same script on another server and it works fine so I'm assuming it's something to do with plesk?

It's just a basic script:

form.php
<form action="process.php" method="post">
Name: <input type="text" name="name" size="20" maxlength="20" /><br />
Email: <input type="text" name="email" size="30" maxlength="30" /><br />
Subject: <input type="text" name="subject" size="30" maxlength="30" /><br />
Text:<textarea name="text" name="text" cols="50" rows="10"></textarea><br />
<input type="submit" name="submit" value="Send" />
</form>

process.php
<?php
@extract($_POST);
$name = stripslashes($name);
$email = stripslashes($email);
$subject = stripslashes($subject);
$text = stripslashes($text);
mail('myeamil@domain.com',$subject,$text,"From: $name <$email>");
header("location:form.php");
?>

Any suggestions?
Thanks.
