I was asked to start researching a replacement for our Barracuda Web and Spam filter. We have roughly 2k exchange users. I understand spam can be due to user behavior on the internet, so I know if we change our solution but users don't change their habits, then we are just trading off for a different set of problems/issues/complaints. I did some preliminary research on the net but see a lot of outdated articles and product promotions.
Anyone have any suggestions as to a good/better solution than a barracuda web and spam filter?
Thanks in advance for any input you may offer.
