... and Bayesian classifier. If the product believes a message is spam it will create a report explaining why it is spam and place the original message as an attachment. Bayesian filters are best used on a per-user basis, especially if you have some users that subscribe to weird groups, like [EMAIL PROTECTED] For example, a company-wide Bayesian filter would never work in my industry (healthcare) as a lot of doctors get messages about topics that would otherwise be classified as SPAM from an adult web site. As far as getting a message for each suspected SPAM, that would just kill me, as I get hundreds of SPAMs a day. I'd suggest Junk-Out, from www.junk-out.com.

RE: SPAM Filtering [7:72265]
I've spent quite a bit of time implementing a spam filtering solution on Windows 2000 and Exchange 2000 in our company. I now have a filter that's about 98% accurate and extremely easy to manage. In fact, I don't touch the spam filter for management purposes at all. Just check it every once in a couple of days to make sure everything's working okay. I use Vircom's Anti-Spam Gate for trapping spam on Windows 2000 and 3 VBScripts I developed myself for allowing users to release their own messages whenever and however many times they want. It's been working flawlessly for a number of months now and I've had very few complaints about false positives. It is possible to use an entirely free VBScript based spam filter using Windows 2000 SMTP OnArrival event but it would require an extensive bit of scripting to get it off the ground. One good aspect of Vircom is that their software and service is quite reasonable and the spam filter database is automatically updated every couple of days. ---Original Message- From: Joseph R.
