Comments
 
As per Microsoft: "IMF writes this event when it is unable to filter a message. Possible causes are corrupted or malformed messages". See ME907691, the link to "Monitoring and Troubleshooting Intelligent Message Filter" and MSEX2K3DB for more details.
From a newsgroup post: "Today I called MS Product Support and they said it is a bug. The IMFv2 generates this error because it can not scan messages above 3MB".
