Hello: I am running Exchange 2003 and using the Intellegent Message Filter (IMF). I have this installed elsewhere without issue. At two new sites however, the IMF does not seem to be detecting any messages. I have set it to take No Action (so that I can monitor it and set the appropraite levels). I have set both the Gateway and Junk threshholds to 1 (that is, monitor all traffic). The checkbox for that SMTP virtual server is checked. However when I launch Perfmon and add counters for each level of "Total Messages Assigned an SCL Rating of X", nothing registers. I know that mail is coming in. Any ideas why I'm not seeing anthing here? Thanks.
