If it's not blocking or at least quarantining files with an exe extension, then your administrator has changed it to allow them. The Barracudas come with .exe files blocked by default. Zip files are also commonly set up by administrators to be blocked or quarantined by the Barracuda Spam Firewall as well. We've had a Barracuda in place for about 3-1/2 years and love it. Also, just because it says it came from tuneboy.com.au doesn't necessarily mean that it did.
