Your results are more the outcome of your settings to block certain attachments than to the Barracuda's prowess in AV detection.
I am not allowed to block attachments, we have a 410, and I regularly see infectious emails come through. Whenever I get an unexpected email with an attachment, I submit the attachment to http://www.threattracksecurity.com/resources/sandbox-malware-analysis.aspx and to https://malwr.com/ and regularly see results that make me shudder... Those submissions are in parallel to my submission to virustotal, and invariably the attachment has already been scanned, and nobody has a signature for it. Mostly, I get these from China (or at least the emails use Chinese character sets.)
