This is a reminder that we will be adding JP as a new list within
multi.surbl.org, as described in the previous announcement:

  http://lists.surbl.org/pipermail/announce/2004-September/000077.html

on Monday September 27th.  JP will have the bitmask value of 64,
which means about half of the WS records will have results that
increase by 64.  We'll probably make the change around close of
business U.S. East Coast time or around 22:00 UTC/GMT.

For now, JP records will continue to be included in WS, but
when SpamAssassin 3.1 gets released, the JP data will come
out of WS and these two will become separate lists within
multi.  Please update your programs accordingly.

SpamAssassin users won't need to make any changes to keep
using WS, but should probably add JP to their configurations
now so that they will be ready for the future change, and
also to gain the significant benefits of the separate JP
list now:

jp - jwSpamSpy + Prolocation data source

Joe Wein's jwSpamSpy program is used both by Joe's own systems
and also Raymond Dijkxhoorn and his colleagues at Prolocation to
process more than 300,000 likely spams per day. The resulting
list has a very good spam detection rate around 80% and a very
low false positive rate below 0.02%. This data is only available
in the combined list multi.surbl.org. 

An SA 2.63 and 2.64 rule and score using SpamCopURI 0.22 or later
looks like this: 

uri       JP_URI_RBL  
eval:check_spamcop_uri_rbl('multi.surbl.org','127.0.0.0+64')
describe  JP_URI_RBL  URI's domain appears in JP at 
http://www.surbl.org/lists.html
tflags    JP_URI_RBL  net

score     JP_URI_RBL  4.0

An SA 3.0 rule and score using URIBL's urirhssub looks like this:

urirhssub URIBL_JP_SURBL  multi.surbl.org.        A   64
header    URIBL_JP_SURBL  eval:check_uridnsbl('URIBL_JP_SURBL')
describe  URIBL_JP_SURBL  Contains a URL listed in JP at 
http://www.surbl.org/lists.html
tflags    URIBL_JP_SURBL  net

score URIBL_JP_SURBL    4.0

JP has approximately the same spam detection and false positive
rates as OB and should probably be scored accordingly.  The
data are not the same however since JP uses different data
sources and Joe Wein's processing algorithms and inclusion
policies.
