Answer 1

using if ($message) {} is a bit tricky, if you want to know the $message contains some text, you would try with is_null or is_set

Alos you may try mocing method before action in your form

<form method='POST' action='notification.php' class='rl'>

Answer 2

One problem I can see is here:

if ($message)
{
  ...
  $email = mysql_result($emails, 0);
}
$body = $message;
...

Now you are trying to send a message, even if $message evaluates to false and you don't have an address to send to.

You need to move the message sending section to within the if ($message) section.

Edit: You are also overwriting your $email variable:

$email= $results['email'];
//echo "$email";
//die();
if(mysql_num_rows($emails) == 0){
  exit("No email addresses found for user '{$_SESSION['username']}'");
}
$email = mysql_result($emails, 0); // get rid of this line

If your commented echo statement already gave the right result, you can get rid of the other, duplicate, assignment.

Apart from that it could be a server problem, mail being delivered to spam, etc. but that is not related to your code.
