Heh, you might not like to hear this, but I think both mailers would be
fine choices, even from a security perspective. I don't recall security
problems in exim, and the only security problem with postfix that I
recall didn't seem that impressive to me -- resource exhaustion. I think
I'd put more faith in there not being any new discovered problems in
postfix, but that is based mostly on Wietse's reputation. :)
Perhaps the deciding factor would be a feature in one or the other that
you need, or their documentation. I've not looked at setting up a
postfix system before, but it looks pretty straightforward. Exim's docs
could probably be published in a volume as large as ora.com's sendmail
book. :) (And yes, this is both good at bad. I was overwhelmed with the
sheer amount of documentation available on exim, but if you ever have
problems with it, chances are good the documentation can help. :)
In short -- I consider it a toss-up. Exim might work better for stranger
email setups, but for most people, postfix might be easier to configure.
