No. Not the RBL. tcp-wrappers has a patch which when applied permits
you to reference a FILE NAME in place of an machine address/name.
Therefore in a hosts.deny you can enter (for example)
pop : /etc/hosts.fylname : DENY
and the file "/etc/hosts.fylname" will be treated as a continuous list
of IP's.
This makes adding an IP to the wrappers rejection list _very_ easy.
FreeBSD 3.3 still did not have this wrappers patch applied, and therefore
I could not utilize this feature of wrappers.
