found on most sendmail setups would have done that for you without need 
for extra entries. You only really need to add the milter-null-* 
variants when you want to reverse or stop a lookup.

milter-null-connect:uuism.net	SKIP

SKIP stops a lookup and returns unknown. You had REJECT, which would 
just black list the domain.

Hmm. Don't think you need this, but then what you had might make sense then:

milter-null-to:      OK

However, milter-null will not reject regular mail, only add a X-Null-Tag.

And for a few days during the transition, you might reject some legit 
DSN/MDN in response to mail sent around the time you installed the 
milter that hadn't yet been tagged.
