Correct, and that's "local configuration customization" at work.

I have advocated the grilling of Ralsky and corrupt Chinese networks,
before anything else.
Default values, particularly for new rules and code are exceedingly
conservative, and have been throughout the SA development process as
far as I can tell. Indeed, no wider testing of this code and accompanying
(or further customized) rules have taken place, yet.

And once again, not all rules work equally well for all people. Anyone
slapping SA on their mail server and not willing to monitor its behavior
or customize it to match local requirements can expect unexpected and
undesired results.
For all its worth: my local scores pertaining to china, Korea, both,
SBL and SORBS-listed space:
score HOSTED_IN_CHINA 4.0
score HOSTED_IN_KOREA 2.0
score HOSTED_IN_CNKR 3.0
score HOSTED_AT_SBL 10.0
score HOSTED_AT_SORBS 5.0
These rules are redefined META rules of the original ones
in Florian's patch along the lines of:
uriip __HOSTED_IN_CHINA eval:check_uriip_rbl('china', 'china.blackholes.us.')
meta HOSTED_IN_CHINA (HTML_MESSAGE && __HOSTED_IN_CHINA && !__HOSTED_IN_CNKR)
describe HOSTED_IN_CHINA Uses a URL hosted in China
tflags HOSTED_IN_CHINA net
[other rules similar, etc.]
Clearly, my default threshold is not 5.0 either.
Back on topic: all involved/interested in URL-based classification
MUST NOT miss the following presentation by Ken Schneider, Brightmail,
about Brightmail's URL filtering:
http://www.spamconference.org/webcast.html
Chose the "Morning 2" session with appropriate bandwidth, and
forward to 1 hour and 4 minutes into the file.
Sorry for the RealDumbProprietary(tm) format.
Brightmail coming out into the open and airing it like this worries
me: they have a history of filing for patents for what they do.
Given that they call this 'tremendously succesful' (or something
along those words), this could become a patent battleground
around the 'next big thing' in spamfiltering technology.
Voice your ideas in public, often and early (= create prior art),
I'd say.
bye,Kai
