Thanks for the quick response. I was just looking at those pages earlier before my post! I'll review them again, but I don't seem to recall recommendations (especially for ultra-newbies) on OS suggestions. I assumed most would state "it all depends", but there has to be a easier route for those who do not have command of the terminal window (yet)....
Of course I am going to start playing/testing with the Open Source solution but I can see us buying into to Zimbra get more advanced features we would want, I'm avoiding Exchange again for many reasons.
Is the Ubuntu tract Linux for dummies by change!?!??
Do you know what direction to point for opinions on OSs?
