Global Opt Out not working

The global opt out feature does not appear to be working. Recipients that have global opt out "selected" are not removed during a Mailout send. They still receive email.

After reviewing the code, it was not clear to me where the feature would have been included.

To get it working I patched the mailout_sendmail function.

Please advise if this functionality exists somewhere else, or review patch for inclusion.

++  // Global Opt-Out is not being observed.  Could not find record of this in issues.
++  $opted_out_addresses = db_query("SELECT email FROM {mailout_list_addresses} WHERE list_id = %d", MAILOUT_GLOBAL_OPTOUT);
  	
  $message_count = 0;
  foreach ($address_list AS $key => $data) {
    
++  // Global Opt-Out is not being observed. Adding catch here. 
++  $not_opted_out = 1;
++	for($i = 0; $i < db_num_rows($opted_out_addresses); $i++){
++		$this_opted_out_address = mysql_result($opted_out_addresses,$i,"email");
++		if ($data['email'] == $this_opted_out_address){
++			$not_opted_out = 0; 
++			break; }
++		}
++	if ($not_opted_out){
  	// Insert db record for each insert
    db_query("INSERT INTO {mailout_message_log} (mlid, email_to, name, html) VALUES (%d, '%s', '%s', %d)", $mlid, $data['email'], $data['name'], $data['html']); 
    $message_count++; 
++   }
  }
