See this commercial vendor's performance numbers, his expensive LSMTP product, and his sizes of machines: http://www.lsoft.com/products/default.asp?item=lsmtp And then go do the same for free with FreeBSD and postfix and maybe softupdates filesystem. Real speed comes from parallel machines and real reliablity comes from redundant machines. So build as many FreeBSD/postfix machines as you need. I know one FreeBSD/postfix user in the financial sector that runs 20 FreeBSD/postfix machines to deliver a 100,000 msgs every morning to list subscribers to stock market lists.
