This week we switched to using Declude Interceptor as our
anti-spam solution. We looked at 3rd party sites like postini and others which are actually very inexpensive at a few bucks a user per year. But because have thousands of users the costs were too high. So I found that Declude's new Interceptor product was exactly what we needed. It runs as an
anti-spam inbound gateway server in our data center that filters the spam before it gets to our mail servers. It was much, much cheaper than Barracuda, Sonic and other solutions we looked at. I would highly recommend it to anyone looking for an ANTI-SPAM solution.
