Fourthed??
We've been running Exim on FreeBSD boxes since... well, since as long as
I can recall (before that it was Smail on a Sparc 5 running SunOS 4.x,
so it was a while ago :-)
Currently we run Exim 4.50 on several different servers. The largest setup
handles 800,000 messages a day on a pair of clustered dual-processor boxes
running FreeBSD 4.11 Messages under 100K are passed through Spam Assassin**
(which has all features enabled plus several additional rulesets), and we
scan messages with two different virus scanners. 85% of all messages are in
the queue less than 60 seconds, 99% less than 15 minutes. And 'top' reports
80-90% idle time on the CPUs most of the time. In fact we can pull the plug
on either one and the other will take over the IP addresses within 3 seconds
and handle the whole load itself in a pinch (great for doing upgrades).
In other words, the combination of Exim and FreeBSD (and I'm sure NetBSD
and OpenBSD would be similar) is an excellent choice (in my opinion).
