We have made the experimental SC2 data into the production SC list. The new version has been tested to catch about 10% more spam than the old version with no significant increase in false positives.
Along with this change is the use of a new data engine which has a shorter cycle time of 5 minutes, and a cleaner, more uniform design and handling of data. This should reduce the overall latency of new additions to the lists by many minutes.
Other resulting changes which may be of minor interest:
1. The list of lists hit for a given TXT record are now in alphabetical order, e.g.:
Blocked, a-pill-MUNGED.com on lists [ab][jp][ob][sc][ws], See: http://www.surbl.org/lists.html
where before they were in bitmask or historical order.
2. Everyone should be using multi.surbl.org now and not the individual lists, but the zone file serial numbers are now synchronized so that multi will have the same serial number as the most recently updated lists, e.g.:
ab.surbl.org ob.surbl.org sc.surbl.org ws.surbl.org multi.surbl.org 1130799782 1130801582 1130799782 1130797982 1130801582
where ob was the only list updated in the most recent cycle above, so ob and multi have the same serial number. In a previous cycle, ab and sc were both updated at Unix (C) time 1130799782 and multi then would have shared that serial number, etc.
Follow-ups, questions, comments, etc. to discuss@ lists.surbl.org
Cheers,
