SURBL: New SC data live, new data engine also

[Jeff Chan <je...@surbl.org>]

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,

Jeff C.
