SBS 2008 Content Filter Updates

For the past month, I have received less than 10 emails in total. How did this happen? I used a combination of IMF Tune v4.1 for Exchange 2007 and TrendMicro Worry Free Business Security Advanced v5.1 beta with Anti Spam setting to medium.

This worked great until yesterday…. Then I started getting few spam messages continuing until today. I had a look to see if the Content Filtering Updates were happening and discovered a whole new world of working with what used to be called IMF in SBS 2003.

This is an excellent article which highlights the differences and how to make the necessary changes to update. http://www.exchangeinbox.com/article.aspx?i=123&t=5
However, I found that some of the steps had already been performed, probably by the tweaked version of Exchange 2007 that ships with SBS 2008.

The general steps are as follows:
1. Enable updates (should already be enabled in SBS2008). Go to Exchange Management Console – Server Configuration – Hub Transport. The action pane on the left shows either Enable Anti-spam updates or Disable Anti-spam updates. You can click and re click to toggle this. When enabling, set everything to Automatic.
2. Check to see that you have the latest update using the Exchange Management Shell. Use the command get-AntiSpamUpdates to check the installed version.
3. Go to Microsoft Updates to see if there is a newer version. You can also subscribe to the Exchange Server 2007 anti-spam RSS feed here – http://catalog.update.microsoft.com/v7/site/Search.aspx?q=exchange%20server%202007%20anti-spam
