> > http://www.beowulf.org/ beowulf is for computation intensive applications. mail is more disk/network intensive. doesn't seem a good match. but i don't really know :). this is all theory since i don't have enough computers to play with beowulf yet. nor do i support 100K email addresses :).
i saw something about this on linuxtoday i think... ah, there it is: http://www-1.ibm.com/servers/esdd/articles/sendmail/index.html didn't understand it though since wasn't paying attention. might be right for you, might not. their setup didn't scale to more than two servers though (plus load balancer in front). that's the part i didn't understand. alternately, would splitting up those users equally over N servers possibly with a front end server serving as an SMTP proxy and matching email addresses with the server that email address is on and proxying to that? but again, that's all theory... you could do it playing MX tricks too like the article says. this, http://staff.washington.edu/~deroest/slides/imap/tsld015.htm is interesting too. not enough details, but might be relevant. you could contact them even, maybe, if you wanted to talk to someone with realworld experience.
