Previously, each SURBL zone file, including the bitmask combined list multi.surbl.org, had testpoitns with A records resolving to 127.0.0.2. That was a design decision, and it was also convenient to the way the zone files were generated before.
But Justin Mason or one of the other SpamAssassin developers argued that multi should have testpoints corresponding to all ones in each bitmask position. So one of the changes with the new SURBL engine now running is that the multi testpionts do have all the bits set for an A record value of 127.0.0.126 instead of 127.0.0.2 .
This may work better with applications that decode the bits properly into individual list results, but it is a change from before and it may break other applications' use of the testpoints.
Does anyone have any comments or preferences for either style?
