Exchange Server 2007 - How To Get Rid of Spam

Recently, I was asked by someone how to configure Exchange Server 2007 to get rid of the spam.  I gave that person a few hints and bingo!  No more spam in the Inbox.  So I thought I would post these here for the benefit of everyone.

Warning: I am not an Exchange expert so if you find something cheesy here, make sure to post a comment.  I sure don't want to mislead anyone.

First thing, make sure that Exchange Anti-spam Update service is up and running.  Ant-spam updates will be pushed via Windows update so make sure you update your server on a regular basis.

Next, in the Server Configuration section, click on Hub Transport and make sure that you see Disable Anti-Spam Updates in the server section in the right of the screen.  If it's disabled, it will say Enable.

Next, in the Organization Configuration section, click on Hub Transport and on the Anti-Spam tab.  You should see the various agents.  Make sure they are enabled.  If you don't see them, run the install-AntiSpamAgents script in the Exchange Management Shell.

Double click on the Content Filtering agent, click on the Action tab and set the actions for your needs.  These settings worked for me so far:

Delete : 9
Reject: 7
Quarantine: 4

That's it, you should see the number of spam diminish drastically.  A bit of a warning, you might play it safe by setting higher settings first and see the results.  You don't want to reject valid emails  ;-)
