I wanted to ask the community about their opinions of spam appliances like Barracuda's firewall vs.hosted services such as Postini. We have been using Barracuda for a few years and we're at a point where we are re-evaluating the solution to see if we should upgrade or shift. What in your eyes, are some of the more note-worthy differences? I understand how they both work, but can't seem to decide if one is better than the other.
Don't get mad if I don't give you points. I try to be as fair as possible.
