To disable Bayesian filtering, set use_bayes
to 0 globally in /etc/mail/spamassassin/local.cf
or for each user in ~/.spamassassin/user_prefs:
use bayes 0
In addition to turning off the BAYES_*
rules, turn off SpamAssassin's auto-learn feature. This is located in the /usr/share/spamassassin/10_misc.cf
file, and can be overridden at the user level in the user_prefs
file too:
bayes_auto_learn 0
