From the website:

How are the entries stored at
The DNS addressing is as follows:
For a given address, a.b.c.d will return one of the following values if a
dns lookup of is performed.                  Verified Open Relay
A verified open relay in most cases is handled by other relay blocklist
servers, and imported into the Zone file.                  Dialup Spam Source
Dialup Spam Sources are imported into the Zone file from other sources and
some known sources are manually added to the local include file.                  Confirmed Spam Source
A site has been identified as a constant source of spam, and is manually
added.  Submissions for this type of spam require multiple nominations from
multiple sites.                  Smart Host (In progress)
A Smart host is a site determined to be secure, but relays for those who are
not, defeating one level of security.  When this is ready, it will be
labeled .  NOTE:  I strongly discourage using outputs
due to it being way too effective to be useful.                  A Spamware software developer or spamvertized
site.  This information will automatically be maintained by shortly.                  A list server that automatically opts users in
without confirmation                  An insecure formmail.cgi script.  (Planned)                  Open proxy servers

You just put the corresponding 127.0.0.x into your local blacklist.
