As I've written previously to this list, I'm a big Exim fan.  If you
check the headers of this message, and any others I write, you'll
note Exim Received: headers.  

Exim is the installed MTA on all my boxs, and is the MTA I usually
recommend for desktop, workstation, and other general use.  However,
while Exim is a superb performer and has an excellent security
history, it is also a monolithic server and thus doesn't have
Postfix/QMail's highly compartmentalised and careful security model.
Further, while the performance curves for Exim and Postfix/QMail can
be made remarkably similar, in __*general*__ without careful tuning
and when under high loads, especially very large spools, my
experience is that Postfix/QMail are going to sustain and perform
better than Exim.
