We have two 400 for incoming and one 200 for out going. The main drawback is, it can't handle volume of emails.
This is the main complaint I see from my clients who have Barracuda. More than one has placed IMGate out front in exactly the same role as IMGate plays for IMail, to remove the 90% of the crap at the envelope stage and allow the next hop system (Barracuda or Imail/stuff) to keep running for years.
IMGate allows running a much cheaper Barracuda, both as a purchase and as annual subscription.
Barracuda is fine as content-filter if you can afford the power of a machine that meets your laod, but of course exactly the same, and more, can be done with free software on generic hardware and no annual subscription.
Looking at the log messages that IMGate logs in talking to Barracuda, Barracuda also runs postfix as MTA, just as IMGate does.
