Normally when a client connection is reject by my sendmail server, the client 
is notified of the Reject message and the client server is generating a NDR. 
This is listed in my log as [1] however when I send a virus it looks like 
sendmail is not reporting the reject back to the client server. How should I 
'enable' this?
