If you really want to use Kolab and are new to it, I would recommend
sticking as closely as possible to the standard install.  It may seem like
a pain to learn postfix, but I'd expect the pain of pulling postfix out and
shoe-horning exim in instead and then configuring it to work the same will
be similar.  Down the road, when you need help or support from the
community, you'll be running a system that's quite different to anyone
else's so you'll find it difficult to get help.

On balance, it probably makes more sense to remove exim from debian,
install something like ssmtp to keep APT happy that you have an MTA
installed and then install kolab which will bind to port 25.

I'm not sure this is a good idea either.  Kolab will install its own
version of postfix.  You'd probably be better off sticking to the kolab
versions.
