Maybe there is, I'm not aware of one. In general, I think you cannot use 
the watermarking feature for detecting back-scatter. It maybe useful 
during a back-scatter storm (but then I'd use something at MTA level), but 
for normal operation I fear it is going to hit too many false postives. 
That is not specific of the MS implementation, it's a general problem of 
this method.
