Question : IMF kb907747

When I applied this update originally, the IMF stopped filtering mail.  I uninstalled and reinstalled kb907747 and it started working.  When I add the custom weight filter XML file and restart the virtual SMTP server it stops working again.  This is on Exchange 2003 SP2.  

Any ideas?

I would suspect that it is the formatting of your XML file then.
Have you tried recreating it from scratch, or breaking down the contents to see which bit of the file breaks the functionality?
