        I was referencing these databases in my second sentence.  I
should have been more clear.

        Nevertheless, these databases are not as complete as they could
be by themselves.  When you implement the first method in addition to
the databases, you block common spam targets to your servers that might
not be covered otherwise.

        An ISP I work for recently implemented an open-relay checking
system and it has already processed 2,034 open relays in 11,715
hosts.  This has virtually eliminated spam.

        Definitely good stuff, I just like the additional measure.
