Linux version of MS Exchange
My company uses MS Exchange for our mailserver and uses Outlook on all the workstations (everything is microsoft windows based here :-x).
I was hoping to try and move some of our servers towards Linux as I have played with a few different flavors over the years, and the main question I have right now is if there is a reasonably close linux based program that will duplicate Exchange, but still work with Outlook running on windows based machines? The version of linux isn't much of a concern as I am currently not running anything, so I would have to start from scratch anyways.
I have read about a few different programs that may do it, but I don't want company bullsh*t about their own program, I want answers from people who have used them if possible.
Thanks for the help,
