Perhaps to combat this, unless I'm missing something, one could justifiably 
deploy GRE filters with source & destination addresses of the exchange 
subnets.  Filtering GRE in general seems nothing more than foolish.


I posted an FYI on how to detect & prevent abuse by tunneling through exchange
points a while ago. I anyone is interested I'll post it again or perhaps
get it put up on the web.
