the differences between post fix and exim

Can some one explain to me their definition as to why I might want to
use post fix instead of exim and why? What apps are post fix good for
what apps are exim good for? Sorry if I start a flame going here but I
am working on a Fedora setup and I have used Linux before just wanna
make sure I know what I am doing.

I've been looking at Exim because it works well with Mailscanner. I
really like Mailscanner (www.mailscanner.info) due to Mailwatch, a
report writer for Mailscanner. Mailscanner works with Postfix, however
there have been issues between the 2.

OTOH, Postfix seems more friendly in regards to dropping in various
anti-spam techniques such as greylisting & RBLS.

My current thinking is that I'll use Mailscanner with Postfix & hope the
Mailscanner people have resolved the Postfix incompatibilities.

BTW: Mailscanner is mostly an interface between the mailer &
Spamassassin / ClamAv.
