Well if it is worth anything, I can't recommend the Barracuda unit. Been evaling the model 150 and so far their support us below, sub-standard. First time I called I got transferred 3 times, and the tech I was talking to had no clue how the product worked. Then last Friday when I called them their phones were down, waited 2 hours before someone called me back then of course got put on hold again for 1 hour before someone was able to help me.
Some other notes, their Outlook Plugin does nothing more than provide search capabilities. They say they support folder organizing but it is only in the browser functionality. My users tend to look for things by folder, so unless they search they can't find whet they are looking for.
Another note is the Barracuda appliances archive EVERYTHING if journaling, you have no way of filtering out what...
