hmm...i don't know...qmail appears to me to be the easiest of them all
due to its utter simplicity (and lack of features/necessary behavior)

I must take a look at exim one of these days.

You could run qmail-smtpd out of xinetd...and run qmail without
daemontools and log to syslog. But if you are into djb's stuff you do
end up using the rest of his good stuff.

When you say multiple instances, I assume multiple queues too?

:D - qmail not suitable for today's Internet as an MX mta without
patching and sendmail a pain to learn/understand if you are not familiar
with m4
