I used the Barracuda Email Security Service for the majority of the month of October 2012 to filter spam for our . During that period of time, we received almost 11,600 emails. Roughly 2,000 were allowed through; 8,600 were blocked, and 1,000 were quarantined. Of the 2,000 allowed, I estimate 600 of them were actually spam.
Technical Support
All calls to Barracuda technical support are routed through receptionists that only take your information and create tickets. I first called one morning and didn’t get a call back until 5:30 pm that evening after I had left for the day. When I called in the next morning to speak with a technician, I was put back in the queue and did not receiving a call until the following morning. The total time to begin addressing my issue was close to 48 hours.
Spam Filtering
I regularly reviewed the last block of 50 emails that Barracuda allowed to pass through. Of those 50, typically 15 (30%) were missed spam. (The number of missed spam ranged from 7 to 27 out of the 50.) Many of the subjects of the messages allowed through contained words that were obviously spam (think improving oneself in bed). Even after ratcheting up all of the custom scoring settings, too many messages were still getting through. To their credit, I was not able to find any false positives. All messages marked as spam were definitely spam.
The Barracuda ESS does provide a mechanism to mark messages as spam. However, it provides no useful feedback to indicate that the message is now spam. Therefore, you could easily mark the same message as spam 3 or 4 times if you reviewed the same block of emails more than once.
Setting up custom policies to filter messages was rather limited. My only options were to enter keywords and then specify if messages matching those criteria should be allowed, blocked, or quarantined. I would have expected some fuzzy logic to handle a phrase like “orders of magnitude,” which could refer to effect of the male enhancement pills or just how off the sales projections were.
