I've been having the same problem, and agree completely. We filter a lot of the garbage forwards containing wav, wmv, etc, and they get through because of a per-user whitelist. We have to archive all of our mail, and this kind of thing exponentially inflates the size of our archives.Aside from the forwards and what they do to the archives, if I choose to block .exe, or .vb files because they're dangerous, for example, I don't care if it's from a trusted (whitelisted) source or not. They shouldn't be attaching potentially dangerous files to e-mail, and I don't want it. This is particularly dangerous because viruses/trojans usually forge from addresses and can get right through the Barracuda. As fast as these things morph and change, it's not unheard of for things to get through before a virus definition is available (happened to us just this morning), and the first line of defense in this scenario already has holes in it.
