Maybe the OP has multiple SMTP servers and is relaying to a dedicated MD 
relay.  If this were the case then the responsibility of generating a DSN would 
fall back to his primary relay, thus giving the illusion that MD was generating 
a separate message.

The only reason I say that is because I'm about to do something like this 
myself.  I'm moving my MD/SA content filtering to a dedicated server, and 
having my primary exchanger relay everything to it as a smart host.  I'm doing 
this to balance out the load primarily, but I realized that since everything 
will come to my dedicated MD/SA machine via my primary relay, and I bounce 
messages with a SA score of 15 or higher, it will end up having to generate 
bounces to most likely non-existent accounts...  I can't think of a way around 
this though.  When my primary relay accepts the message in order to relay it to 
the dedicated MD/SA server, it has accepted ultimate responsibility for that 
message's delivery.  I guess I will just have to put up with an abnormally 
large mail queue on that server...
