I am currently doing a review of two completely different products to act as filters for a Gentu Linux mail server. I just wanted to post to see if anyone has dealt with either the Barracuda hardware or the BitDefender software for Linux. I have to compare the two to see which one our company will use as a spam, spyware, and virus filter for our email system. Has anyone used either of these systems before? Which one do you think would be better? Right now I am leaning towards the Barracuda myself because it is a hardware filter and requires no user fees. Has anyone had any problems with one or the other? Thanks for any assistance you can provide me.
