[Bug 4484] New: Rules causing massive FPS in europe/japan
http://bugzilla.spamassassin.org/show_bug.cgi?id=4484
Summary: Rules causing massive FPS in europe/japan
Product: Spamassassin
Version: 3.1.0
Platform: Other
OS/Version: other
Status: NEW
Severity: major
Priority: P5
Component: Rules
AssignedTo: dev@spamassassin.apache.org
ReportedBy: mbr@freebsd.org
OBSCURED_EMAIL Message seems to contain rot13ed address
Many japanese mails are matching here. The FPS rate
is catastrophal. From 40 mails today matching this rule,
15 are HAM. And I can see this from different adresses.
SUBJ_ILLEGAL_CHARS
>From 500 mails today, 82 are definitly not spam. The problem
seems to be that many french mailprogramms, and also german
autogenerated subject contain umlauts and aren't iso-encoded.
This rule may work in the US, but it does definitly not
work in europe.
These two scores need definitly adjustment.

-0.2 (since I might be misreading this):
+# score OBSCURED_EMAIL 0
+# Speakers of any language that uses non-English, accented characters may wish
+# to uncomment the following lines. They turn off rules that fire on
+# misformatted messages generated by common mail apps in contravention of the
+# email RFCs.
+
+# score SUBJ_ILLEGAL_CHARS 0
It would seem to me that OBSCURED_EMAIL should also follow the doc change, no?

imo, no. we can't imagine all the situations people may want to disable certain
rules -- for example those are in user_prefs, and we already know that many
people don't have per-user preferences set up, some others load them from SQL,
etc.
Hooking that kind of logic into the install code would be asking for trouble...
btw still needs 1 vote. (in the "+1" style ;)

Triage: Martin, are these non-spam hits from Yahoo? See bug 4352 -- if all (or
almost all) are from Yahoo, then Justin's proposed solution in that bug may be
viable. If these aren't associated with Yahoo, then we need to look at other
options. Thanks.

Scores are in the process of being adjusted. You're welcome to contribute to the
rescoring process! :-)
Hopefully, these rules will have better scores after the rescore.

well, the OBSCURED_EMAIL rule has the same limitations as the rules listed above
it, which already have their own documenting comment. hence it doesn't need an
extra one.

Good enough for me.
Thought for 3.2 -- Should there be an install option which automatically
deactivates these rules (perhaps loading these "score 0"s into a new
51_scores.cf file) for sites where any significant number of valid emails are
non-English? Perhaps an option for major families (ie: European emails still
flag Asian languagues and v.v.)?

No. the OBSCURED_EMAIL hams are from japanese mail-adresses mostly.
The SUBJ_ILLEGAL_CHARS adresses are from mails in germany and french.
