On the client side I've installed Spambayes (http://spambayes.sourceforge.net/windows.html) for Outlook XP. My wife raves about it. I believe it catches about 99% of the spam she receives (which is a lot). I moved to this after cloudmark spamnet (another good product) started their subscription service.
I myself am using Outlook 2003 which does a fabulous job (as mentioned earlier). I also use nemx powertools for exchange 5.5 at work (http://www.nemx.com/index.asp). This does not move the spam into another folder in the users mailbox. It moves it to a specified mailbox or deletes it. It is a really good product that will filter on headers, RBL, subject, address, and content. It does take significant effort to maintain and configure the rules. I believe the first two options are more what you are looking for. Spambayes is OSS. There are tradeoffs on the client vs. server spam filtering. There may be less administrative effort to do the client side if your users are fairly computer savvy. If they aren't you need to think about deployment and training costs. The upside is, the user is still responsible for maintaining their email. You just make sure everything addressed to them gets to their inbox. When installed on the server side, you always have to worry about blocking legitimate work related e-mail. For instance a default block for nemx is the word casino. However, what if there are meetings scheduled at a conference room at the casino? Oops, I didn't get that invite, the message was blocked. Users may complain that they didn't get personal emails (they contained swears). You need a process in place for maintaining rules. A new spam is getting through the filter - who do the users report it to? Who adds a new rule? Who decides what rules are implemented? How do you rectify false positives? If you have savvy users, or a smaller number of users, I think the client side filtering is the way to go. For large numbers of users, the server side is the way to go. Of course, this is just my humble opinion. Consider the can of worms opened. :) Jordan Arendt -----Original Message----- From: Jason Benway [mailto:[EMAIL PROTECTED] Sent: October 21, 2003 11:34 AM To: '[EMAIL PROTECTED]' Subject: [ActiveDir] OT: enterprise Spam blocking products I started testing different spam products for our company. I'm testing GFI right now. I'm really like Ihatespam Gateway edition, but it has limitations because of CDO. What I'm looking for a software that will move "spam" into a user's folder other than the inbox without the user having to setup a filter in outlook. I would also like for the user to have the ability to 'tell' the software when it missed a spam message or incorrect tags a message as spam. I would prefer a product that does not run directly on the Exchange box. We are currently running Exchange 5.5 in a cluster. I know I'm asking a lot, but I thought will everyone's help I could find a product that is close.
