Just so you know you might want to add some headers so it is less likely to be flagged as spam...
PHP Code:
$headers = "MIME-Version: 1.0\n";
$headers .= "Content-type: text/plain; charset=iso-8859-1\n";
$headers .= "X-Priority: 3\n";
$headers .= "X-MSMail-Priority: Normal\n";
$headers .= "X-Mailer: php\n";
$headers .= "From: Your Site <noreply@yoursite.com>\n";
mail($to,$subject, $body,$headers);
Add the $headers section and change the mail() function to the one above.
