[CentOS] [OT] Anyone on-list using a Barracuda Spam Firewall?

Normally I don't like posting on this list for off-topic info, but I need to
know "un-biased" opinions regarding Barracuda's Spam Firewall as we're
looking to get one soon where I work and I want to know any pros/cons before
I stake my credibility on it for our spam fighting.

If you've had good or bad experiences with one of these devices, please
contact me _off_ list regarding this. I don't want to spam the list with a
major OT thread. Thanks.
