If you are having problems sending email from your site, this is an easy script to help you verify that php's mail() function is working.
On your site create a new file called phpmail.php and copy in the following contents:
<?php
$email = $_GET['email'];
$subject = "test";
$message = "test";
mail($email, $subject, $test);
?>
Then go to www.yoursite.com/phpmail.php?email=you@email.com. Replace yoursite.com with your domain and you@email.com with any email address. You should receive an email at that address.
