Thanks all,

For some reason, I brain-farted today and was thinking this worked the other 
way around. It is commented (by default on RH distros).

I guess the milter-ahead might be the way to go. I usually see about 50 
mails waiting for these unresolvable addresses, but recently, it's climbing 
steadily. I don't know how much time in CPU cycles sendmail takes to retry 
these, but I do notice a little slowness.
