[Note that this change was actually made about a year ago, around
November 1, 2005. I hope the delayed notification doesn't cause
any major issues.]
Previously, each SURBL zone file, including the bitmask-combined
list multi.surbl.org, had testpoints 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 set for each bitmask position. So testpoints for
multi.surbl.org now have all the bits set for an A record value
of 127.0.0.126 instead of 127.0.0.2 .
(If a new list is added in future using the 128th bit, then the
new testpoint values in multi will be 127.0.0.254)
This may work better with applications that decode the bits
into individual list results, but it is a change from before and
it may break other applications' use of the testpoints.
The multi.surbl.org BIND zone file contains:
test.surbl.org 604800 IN A 127.0.0.126
604800 IN TXT "multi.surbl.org permanent test point"
test.multi.surbl.org 604800 IN A 127.0.0.126
604800 IN TXT "multi.surbl.org permanent test point"
surbl-org-permanent-test-point.com 604800 IN A 127.0.0.126
604800 IN TXT "multi.surbl.org permanent test point"
2.0.0.127 604800 IN A 127.0.0.126
604800 IN TXT "multi.surbl.org permanent test point"
The multi.surbl.org rbldnsd zone file contains:
test.surbl.org :126:multi.surbl.org permanent test point
test.multi.surbl.org :126:multi.surbl.org permanent test point
surbl-org-permanent-test-point.com :126:multi.surbl.org permanent test point
2.0.0.127 :126:multi.surbl.org permanent test point
