Thanks for that (really quick) reply, active forums are nice.. Yeah, i actually read the script you are referring to (and a few other) and i think it's a really slick solution, two syncs to minimize downtime and let the occational mail just wait on the sending MTA for a few minutes. That downtime is not accepable according to my spec though (say we have a 400k mails, just to STAT those files would take a while no matter how i do it).
Thanks for your answer, i'll have another round thinking about it
