Can anyone, who has used both Postfix & Exim please share some experience with me? Which of these 2 did you prefer to use, and why?

cPanel uses Exim (and AFAIK, only Exim), VirtualMin seems to use Postfix by default and often times when a custom server is installed a client doesn't know which to use so we recommend Exim. But, what are the differences between these 2, from your experience, if you don't mind telling me?

I have used Qmail on FreeBSD 4.8 last and don't even consider this as a good mail system anymore, so I'm not even looking at it right now.

from my experience postifx tends to be easier to troubleshoot, configuration files are easier to understand and seems lighter than exim.
