Porting mail routing DLL to SMTP Event Sink   

I'm porting an old exchange server 5.5 mail routing DLL to a SMTP Event Sink.  

The plan is to keep the existing code and wrap the call to 
rcRouteInboundMail with a ISMTPOnArrival interface.

All is going well except that I can't find any documentation on the 
rcRouteInboundMail function and the possible DISP_ return values.

Any help is greatly appreciated.
