rbldnsd does not support dynamic updates like bind.  But there is no 
reason you can not create a script in any language to update the zone 
file.  When rbldnsd detects that the zone file has been changed, it auto 
reloads it.

In my situation, when I place a new zone file in place, rbldnsd auto 
loads the new one.
