DESCRIPTION
This plugin implements simple, test-based shortcircuiting.
Shortcircuiting a test will force all other pending rules to be
skipped, if that test is hit. In addition, a symbolic rule,
"SHORTCIRCUIT", will fire.
Recomended usage is to use "priority" to set rules with strong S/O
values (ie. 1.0) to be run first, and make instant spam or ham
classification based on that.
CONFIGURATION SETTINGS
The following configuration settings are used to control
shortcircuiting:
shortcircuit SYMBOLIC_TEST_NAME {ham|spam|on|off}
Shortcircuiting a test will force all other pending rules to be
skipped, if that test is hit.
Recomended usage is to use "priority" to set rules with strong S/O
values (ie. 1.0) to be run first, and make instant spam or ham
classification based on that.
To override a test that uses shortcircuiting, you can set the
classification type to "off".
on Shortcircuits the rest of the tests, but does not make a strict
classification of spam or ham. Rather, it uses the default
score for the rule being shortcircuited. This would allow you,
for example, to define a rule such as
body TEST /test/
describe TEST test rule that scores barely over spam threshold
score TEST 5.5
priority TEST -100
shortcircuit TEST on
The result of a message hitting the above rule would be a final
score of 5.5, as opposed to 100 (default) if it were classified
as spam.
off Disables shortcircuiting on said rule.
spam
Shortcircuit the rule using a set of defaults; override the
default score of this rule with the score from
"shortcircuit_spam_score", set the "noautolearn" tflag, and set
priority to "-100". In other words, equivalent to:
shortcircuit TEST on
priority TEST -100
score TEST 100
tflags TEST noautolearn
ham Shortcircuit the rule using a set of defaults; override the
default score of this rule with the score from
"shortcircuit_ham_score", set the "noautolearn" and "nice"
tflags, and set priority to "-100". In other words,
equivalent to:
shortcircuit TEST on
priority TEST -100
score TEST -100
tflags TEST noautolearn nice
shortcircuit_spam_score n.nn (default: 100)
When shortcircuit is used on a rule, and the shortcircuit
classification type is set to "spam", this value should be applied
in place of the default score for that rule.
shortcircuit_ham_score n.nn (default: -100)
When shortcircuit is used on a rule, and the shortcircuit
classification type is set to "ham", this value should be applied
in place of the default score for that rule.
TAGS
The following tags are added to the set available for use in reports,
headers etc.:
_SC_ shortcircuit status (classification and rule name)
_SCRULE_ rulename that caused the shortcircuit
_SCTYPE_ shortcircuit classification ("spam", "ham", "default", "none")
