New ABUSE sublist -- SC, AB sublists deprecated -- migration to ABUSE

December 18, 2015

In order to keep improving SURBL data, we plan to reorganize some of
the sublists inside the combined list multi as described below.

SC, AB sublists deprecated, merged into ABUSE sublist with JP

Until now the SURBL multi data set consisted of the two typed sublists
MW (malware) and PH (phishing) and several general data sets (AB, JP,
SC and WS), each with its own bit mask value. To simplify the use of
multi and to prepare for more detailed typing information in the
future we will be merging the above general lists into a single
sublist that will be known as ABUSE. All domains listed on ABUSE will
return bit mask 64, the value previously used by the JP sublist.

Effective immediately, the SC and AB data sets have been migrated and
are already part of ABUSE, as is the JP data set. These migrated data
sets now no longer return bit mask values 2 (SC) and 32 (AB) but 64.
Their old bit mask values have been deprecated.

WS sublist to be deprecated after transition period

The WS sublist will be migrated into ABUSE (bit mask value 64) after a
transition period, per the timeline at the end of this announcement.
Its old bit mask value 4 will then be deprecated.

For compatibility with existing applications, any TXT records for
hosts listed on ABUSE will continue to identify the sublist name as JP
until the end of the transition period. To existing unmodified
applications it will appear that the SC and AB sublists have been
emptied and their data added to the JP sublist.

Generally we recommend that application developers not depend on
particular TXT records, as  they are meant for human readers (for
example, in non-delivery messages) and are subject to change without
notice. Applications should always use the numeric (A record) return
values from DNS queries instead.


Deprecation of the SC, AB sublists - Immediate
  AB => bit mask value 64
  SC => bit mask value 64

Migration of WS dataset to ABUSE - 1 May 2016
  WS => bit mask value 64
  renaming of ABUSE TXT record

The documentation on the SURBL site will be updated over the next few
weeks to reflect the changes. It has not been updated yet.


Recommended action

We recommend that SURBL application developers prepare to update their
configurations according to these changes so they are ready when the
changes are put into production on our name servers and zone files.

Please direct followup discussion to the SURBL Discussion list.
