I'm looking for recommendations on SPAM filtering for a small business (law firm) using Exchange 2K/Outlook XP for email. Not sure whether it would be best to go with filtering at the gateway/server level or using client-level software. I'd appreciate any recommendations of which way to go and any specific software experiences or recommendations. Thanks!

I'm in the same boat, getting ready to put MXEXCH 2k onto the outside. From what I've heard, the best approach is to put tools on both the server and the clients. On the server you can control blocking for all users; things like whole domains fromforeign countries. At the client level the user will need the ability to allow stuff he wants, and exclude the crap. I have Unix friends who swear by SpamAssassin ( they say it makes getting spam fun), I'm just starting to look at that one. There'sanother tool that I've seen a lot of ads for but have not looked is IHateSpam.
I'd also recommend looking at a specific Exchange antivirus product along with the Spamfilter. Trend Micro makes some nice products that are designed to work together.Dave B

Thanks! I'll take a look at those definitely. We already use Symantec Antivirus/Filtering on the Exchange server - we're very happy w/it as far as virus protection, but the content filtering included with that product requires a lot of custom configuration and seems kinda clunky to me.

My law firm uses WorldSecure - now Tumbleweed Secure Mail. It can be difficult to get used to, but once you're there, it certainly does its job.

We use a combination of this at the firewall and user education. We've set up an Exchange mailbox for the users to forward any more spam that does get through. Using these messages, we continue to tweak the settings on the server.
