After getting past some initial DNS problems (my bad) the install and
setup of Scalix went quite well. Very easy to install and setup was a
breeze. Quite impressed with that part of it.

I'm now testing out the program it self and will soon test out the
outlook connector. Hoping they have an import feature for PST files
like Zimbra.

So far though it's not a bad little system.

Groupwise is next on my list. I wish I had enough experiences to write
a nice comparison, but I don't.
