The amount of emails to be delivered does not in my opinion affect how fast it needs to happen. Your local MTA will take a while to deliver those emails anyway, so the time from script to user is mostly dependent on that, which means you're left with reducing the time from script to MTA. If you need to finish the script fast (in order for some user-intercation to continue perhaps), I would would just detach the script and carry on. /Per Jessen, Zürich -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
