NAME

       Mail::SpamAssassin::Plugin::AccessDB - check message against Access Database

SYNOPSIS

	 loadplugin	Mail::SpamAssassin::Plugin::AccessDB

	 header   ACCESSDB  eval:check_access_database('/etc/mail/access.db')
	 describe ACCESSDB  Message would have been caught by accessdb
	 tflags   ACCESSDB  userconf
	 score	  ACCESSDB  2

DESCRIPTION

       Many MTAs support access databases, such as Sendmail, Postfix, etc.  This plugin does similar checks to see whether a message would have
       been flagged.

       The rule returns false if an entry isn't found, or the entry has a RHS of OK or SKIP.

       The rule returns true if an entry exists and has a RHS of REJECT, ERROR, or DISCARD.

       Note: only the first word (split on non-word characters) of the RHS is checked, so "error:5.7.1:..." means "ERROR".

NAME

       Mail::SpamAssassin::Plugin::AutoLearnThreshold - threshold-based discriminator for Bayes auto-learning

SYNOPSIS

	 loadplugin	Mail::SpamAssassin::Plugin::AutoLearnThreshold

DESCRIPTION

       This plugin implements the threshold-based auto-learning discriminator for SpamAssassin's Bayes subsystem.  Auto-learning is a mechanism
       whereby high-scoring mails (or low-scoring mails, for non-spam) are fed into its learning systems without user intervention, during
       scanning.

       Note that certain tests are ignored when determining whether a message should be trained upon:

       o   rules with tflags set to 'learn' (the Bayesian rules)

       o   rules with tflags set to 'userconf' (user configuration)

       o   rules with tflags set to 'noautolearn'

       Also note that auto-learning occurs using scores from either scoreset 0 or 1, depending on what scoreset is used during message check.  It
       is likely that the message check and auto-learn scores will be different.

USER OPTIONS

       The following configuration settings are used to control auto-learning:

       bayes_auto_learn_threshold_nonspam n.nn	 (default: 0.1)
	   The score threshold below which a mail has to score, to be fed into SpamAssassin's learning systems automatically as a non-spam
	   message.

       bayes_auto_learn_threshold_spam n.nn	 (default: 12.0)
	   The score threshold above which a mail has to score, to be fed into SpamAssassin's learning systems automatically as a spam message.

	   Note: SpamAssassin requires at least 3 points from the header, and 3 points from the body to auto-learn as spam.  Therefore, the
	   minimum working value for this option is 6.

       bayes_auto_learn_on_error (0 | 1)	(default: 0)
	   With "bayes_auto_learn_on_error" off, autolearning will be performed even if bayes classifier already agrees with the new
	   classification (i.e.  yielded BAYES_00 for what we are now trying to teach it as ham, or yielded BAYES_99 for spam). This is a
	   traditional setting, the default was chosen to retain backwards compatibility.

	   With "bayes_auto_learn_on_error" turned on, autolearning will be performed only when a bayes classifier had a different opinion from
	   what the autolearner is now trying to teach it (i.e. it made an error in judgement). This strategy may or may not produce better future
	   classifications, but usually works very well, while also preventing unnecessary overlearning and slows down database growth.
