When using Intelligent Message Filter (IMF) with Exchange 2003 SP2 it is possible to download filters manually and then upload them to the Exchange server. Why would you want to do this I hear you ask, well if you have an Exchange server that is part of a secure network and does not have access to the Internet but you still require SPAM filters, you can access the filters manually then upload them into Exchange.

The following site allows you to download IMF filters manually - https://catalog.update.microsoft.com/v7/site/Home.aspx

Once the filter has been downloaded you can then upload the filter to exchange by running the following commands:-

To manually install an update or roll back to an earlier version
