All, I bought a Barracuda Model 400 last October. My current setup is as follows: Barracuda GW ---> Internal servers ---> Spamassassin server ---> Quarantine or local delivery.
Although there was a small percentage of spam being caught by adding the Barracuda, this was because I added my own Regex rules on the Barracuda. Without my Regex rules, using their "intent" RBL, a trained bayes, and SBL-XBL RBL, the devise gave me nothing in terms of more spam captured than Spamassassin with SARE. In fact, I don't have concrete numbers but I am willing to put $100 and say SA/SARE does better. Because I am a customer, I have access to the Barracuda Networks forums. I am not the only one unimpressed and since it's a moderated forum, all the postings I have made which have a negative undertones, do not get posted. OK, enough of that. I bought the server in October (8 months ago) for about $4800. This included a years license. Well, the server has a bad drive based on their support's diagnostics. They want me to pay $899 to have it replaced! FWIW, if you open the box yourself, it voids support. I want to say that if your thinking of buying one of the Barracuda Networks Spam Firewall (www.barracudanetworks.com), save your money!. I would have been better off spending about $2000 for two decent servers and running SA/SARE at the perimeter. I hope this helps somebody else from making the same mistake. Brian
