Know Your Limits
IMF installation is simple, and the only signs you'll have of the new add-on are the addition of an Intelligent Message Filtering tab in the Exchange System Manager (ESM) Message Delivery Properties dialog box (which you can access through the Global Settings\Message Delivery node) and a new ESM Intelligent Message Filtering node (under the Protocols\SMTP node for the Exchange server that's running IMF). After IMF installation, open ESM and open the Message Delivery Properties dialog box, then go to the Intelligent Message Filtering tab, which Figure 1 shows, to set SCL thresholds for gateway and Store processing and to set an action to occur when spam is blocked at the gateway. (Note that the Store threshold, which you set under the Store Junk E-mail Configuration section, must be lower than the gateway threshold, which you set under the Gateway Blocking Configuration section.) Like other Global Settings, these settings apply to all servers within the Exchange organization. . . .
