Blocking Delivery Status Notifications?

[Julian Field]

 From the Bat Book (O'Reilly sendmail book), if you rebuild sendmail with
ENVDEF=   -DDSN=0
in your Makefile, it should disable all DSN support.

You will probably find your Makefile in one of the obj.* directories in the
sendmail build tree. Build it once using the defaults (as that will also
create the sendmail Makefile specific to your system), then tweak the
Makefile and rebuild just the sendmail binary.
