Is there anyway you could break this up into managable chunks maybe. I'm currently doing something similar in that I'm writing a PHP based list server app that uses a heirarchical grouping system, but mine is broken done into smaller chunks based on group and user permissions. What if you did a 1 second sleep between each user send? While it would take a very long time to parse through the list of users the mail server would still be able to respond quickly and not have PHP timeout.
