Re: Barracuda Spam Filter

[Tony Harris <harrist () CCV VSC EDU>]

Can you point me at any info that documents the Barracuda as being a Linux
and SpamAssassin box?  There's nothing on their website that indicates that,
unfortunately, and I'd like to see what they have to say about doing so.

(Also, if that's the case, given that both are OpenSource, don't they have
to acknowledge their use of them somewhere public?  At least out of
fairness?  I know, silly me for expecting fairness to win in cases of
corporate interest...)
