Why isn't IMF Tune processing any emails?

You need to make sure that IMF is enabled at the Exchange System Manger and also that IMF Tune is enabled at the configuration.

Exchange 2003 SP2 changed the interface for enabling IMF. Thus make sure to follow the procedure matching your current Exchange SP version.

Enabling IMF - Exchange 2003 SP2 and Later

1. Open the Exchange System Manager

2. Browse the left pane tree and open the properties for:
   <Organization> | Servers | <Exchange Server> | Protocols | SMTP | <SMTP Virtual Server>

   Note that <Exchange Server> is effectively the name of the Exchange Server where the Intelligent Message Filter is installed.

   

3. From the General property sheet click on Advanced.

   

4. In the Advanced dialog that opens select the IP on which IMF is to be enabled and click on the Edit button.

   

5. Set the 'Apply Intelligent Message Filter' checkbox.

   

6. Save changes.

Enabling IMF - Exchange 2003 SP1 and Earlier

1. Open the Exchange System Manager.

2. Browse the left pane tree and open the properties for:
   <Organization> | Servers | <Exchange Server> | Protocols | SMTP | Intelligent Message Filtering

   Note that <Exchange Server> is effectively the name of the Exchange Server where the Intelligent Message Filter is installed.

   

3. The property sheet will show the list of virtual servers for the local Exchange Server on which IMF may be enabled. Tick the checkbox next to the virtual servers.

   

4. Click OK to save changes.
