You could call yourself kinda lucky.
Most of the people in our office address our mailserver by its internet DNS 
which makes them route the traffic via the router.
I have excluded the /24 range in which our IPs are, but strangely I had 2 
occassions in which the exclude suddenly went include and killed off half 
the office untill I restarted RBLDNSD.
As a security I now have it restart at 1AM and 1PM.

What I did find in the past on your problem was that !1.2.3-4 doesn't work 
it had to be !1.2.3.0/23 or it wouldn't work.
