From Newsgroup: news.groups


newsgroups can receive dozens or even hundreds of articles per day;
scoring rules can be used to automatically separate these articles
into categories: first, by analyzing common "xover" message header
fields then applying scores and actions to those affected articles;
second, by analyzing all header fields in articles which have been
downloaded and scoring them accordingly: e.g. from, subject, xpost,
message-id, injection-info, nntp-posting-host, references, x-abuse,
path, x-trace, x-face, x-no-archive, x-complaints-to, x-newsreader,
x-mailer, x-tor-router, x-spam-checker-version, xref, mime-version, x-orig-path, x-organisation, organization, originator, in-reply-to,
reply-to, cancel-lock, content-language, content-transfer-encoding, content-type, user-agent, followup-to, lines, x-dmca-notifications,
x-received, x-antivirus, x-antivirus-status, x-abuse-and-dmca-info, x-received-bytes, x-usenapp, x-complaints, x-postfilter, x-user-id,
x-ufhash, x-server-commands, x-usenet-provider, newsgroups, etc...

by downloading several hundred article headers in a busy newsgroup,
overview scoring rules can be tested; after retrieving the message
bodies, both overview and non-overview scoring rules are tested on
all message headers; cursory inspection of these retrieved article
headers can reveal headers and/or header field text strings unique
to certain newsservers that allow posting, including websites that
use backend nntp, and mail-to-news gateways popular with anonymous
remailer users...non-overview headers can be especially useful for
this; a clean "portable" install of 40tude dialog 2.0.15.41 is the
best place to begin (do not install to default x86 program folder):

after setting up this program to work with one or more newsservers,
copy and paste the following, relatively simple example of scoring
rules into the "scoring and actions" window, "test expressions" to
validate scoring syntax then click ok; the wildcard [*] identifier
includes all newsgroups; try it on headers, then on message bodies:
