We average about 40,000 emails a day and the Barracuda causes about a 1-2 second delay. Not sure about the actual throughput.

And for anyone out there that is a big proponent of open source, the Barracuda is essentially a Linux box with about a dozen or so software packages that, of course, are also tweaked by Barracuda.

Anyways, there start at under $1,499 I think and is a hell of a product. 15 minute setup and basically forget it's there after that.

I went to a seminar on Barracuda just yesterday and am considering purchasing their web filter and/or messaging archiver as well.
