I had good luck with a pass-through server. I'm using a 3ghz, 2g ram system, that handles only about 8k mail a day for around 500 users. It bogs down even then, because of the incredible huge stream of spam coming in day or night. It just maxes out on number of concurrent connections, I set my limit to 20 concurrent. I think ram is the most important item and a pre-forked spamd or mimedefang preforked spamassassin process. The nice thing about relays is you can scale linearly by just adding in more machines. I'll add in another pass-through machine when I finally configure it so the mail can only go through the relay's to hit the internal mail.
I've found even my temporary solutions turn into production solutions, and I'm stuck with whatever hardware I originally used. So start with decent hardware to begin with...not great...but decent. --Luke Ronald I.
