Adapt your script to send a second email.

mail($to, $subject, $message);
if (isset($_POST['email'])) {
  // perform a check here to make sure it's an email
  // for example, if you're using PHP 5.2 or above
  $valid = filter_input(INPUT_POST, 'email', FILTER_VALIDATE_EMAIL);
  // after the check, send a message
  if ($valid) {
    mail($_POST['email'], 'Thank you for contacting us',
      'Thank you for your comments. We will be in touch shortly, if necessary.');
  }
}
