SCL Missing in Exchange Email

Hello

We have an Exchange 2003 SP2 server with Intelligent Message Filtering turned on.  We are seeing a lot of spam messages get past the IMF and make it into user's inboxes.  

I noticed than on all of the messages that get through, their is no SCL rating in the header.  Any message that has a SCL rating is properly recognized as spam.

Why would some messages not have that, is it a configuration problem with Exchange, IMF, etc....

Thanks

Are you sure the messages are coming in through the Exchange server? There is almost no white listing on Exchange 2003 IMF, so it odd that some messages are not being scanned at all. Anything else on the Exchange server? AV for example, something that could be interfering with the traffic?
