I'm running exim on a celeron 1.2ghz with 256mb ram and 20gb ide. It's not
doing imap, just pop. It does have mysql server and all users are virtual.
I tried to mvoe as much of the config to sql as possible. The userbase here
is >200 users.

The load of the machine doesn't often hit 1. It's also doing virus scanning
(but not spam scanning. I don't like spam assassin) using mcafee. One
thing is the users here don't seem to notice if there's a 1-2 second delay.
I used to run the same setup on a dual pentium 233mmx, 256mb ram and 20gb
hdd. Users still did not notice the speed difference after the upgrade.
