Good idea, imho.

I personally use RBL and ORBS (that latter with a method to circumvent it)

The ORBS website says the following about bone.xtdnet.nl:

Database Check - 194.229.18.5 

        194.229.18.5 is in our manually maintained database for the
        following reason:

        open relay, blocking the ORBS tester. (25 January 2000)

        If this problem has been fixed, please E-mail
        StaticListings@localhost to be removed from the database.

Maybe you should contact this address (I hope they're not using ORBS to
filter Email there :). They should have a sample of an open relay test
message on file, possibly together with spam sent through your relay.
