What I was referring to, in context, was not disabling either: 1. MTA blacklists 2. SpamAssassin URIDNSBL The context of the original message does not mention MTA blacklists used in SpamAssassin, though your comment about using them there may be mostly correct. (SA may use the MTA-type blacklists in ways not purely MTA-like, so the overlap that you're thinking of may not be 100%.) Jeff C.
