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.Recommended 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.
Recommended 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 onThe 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")
