[Bug 7390] New: razor2 rule scores
https://bz.apache.org/SpamAssassin/show_bug.cgi?id=7390
Bug ID: 7390
Summary: razor2 rule scores
Product: Spamassassin
Version: unspecified
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P2
Component: Rules
Assignee: dev@spamassassin.apache.org
Reporter: jquinn+SAbug@pccc.com
Target Milestone: Undefined
From RW on https://bz.apache.org/SpamAssassin/show_bug.cgi?id=7351:
I think there is a problem here. For a while this month the razor score was
above 4.5 points, and at that level a razor FP combines with BAYES_50 to
produce a misclassification at the default threshold. The current rules are
over-complicated and make it hard to put a sensible limit on the score.
Engine 4 fell-off a long time ago leaving only engine 8.
RAZOR2_CF_RANGE_E8_51_100 and RAZOR2_CF_RANGE_51_100 are now duplicates, so
RAZOR2_CF_RANGE_E4_51_100 and RAZOR2_CF_RANGE_E8_51_100 are now both
superfluous.
Engine 8 produces mostly high confidence results, in the mass checks
RAZOR2_CHECK only hits 0.3% more spam (for 44% more ham). Its precise score
wont be all that important - provided it's low.
What I would suggest is something like:
- Remove RAZOR2_CF_RANGE_E8_51_100 and RAZOR2_CF_RANGE_E4_51_100
- Fix the score for RAZOR2_CHECK at 0 1.7 0 0.8
- Limit the score for RAZOR2_CF_RANGE_51_100 to 2.7

Created attachment 5447
--> https://bz.apache.org/SpamAssassin/attachment.cgi?id=5447&action=edit
Patch against 3.4.1 to remove Razor2 engine 4 and consolidate engine 8 rule.
Patch created following the recommendations:
Removed the E4 and E8 rules and scores. Moved the E8 scores to
RAZOR2_CF_RANGE_51_100 in 50_scores.cf. This should keep the max total RAZOR2
score a point or two lower than before.
