Okay, that could seriously hamper a lot of servers if the total starts to rise above about 50/100 at a time (depending on how powerful the server is).

If you change the 'true' to 'false' in this line, then they will go to the queue system.

vbmail($user['email'], $subject, $message, true);

That's still a problem for most people, but it is at least then solvable with something like my cron based mail queue processing.
