Jeff, As far as I remember, one of RBL and ORBS only blacklists hosts that have become spam relays and then failed to heed several warnings, and the other blacklists anyone with open ports that could become spam relays in future. Or something. Unfortunately I can't remember which is which! But most people here seem to think that the first approach is sufficient, and that the second blocks an unacceptably large number of innocent messages.
Of course, as an archive rather than delivering the email straight to people, you may be willing to live with more false positives. But personally I would be tempted to turn on the more gentle one first. Whichever it is. :) -- Stephen Turner http://www.statslab.cam.ac.uk/~sret1/ Statistical Laboratory, Wilberforce Road, Cambridge, CB3 0WB, England "The Hubble Space Telescope has shut itself down, preventing astronomers from making any observations of the Universe."
