Bayesian Filter

Technology / Email / Bayesian Filter: An anti-spam program that evaluates header and content of incoming email messages to determine the probability that it is spam. Bayesian filters assign point values to items that appear frequently in spam, such as the words 'money-back guarantee' or 'free'. A message that accumulated too many points is either rejected as probable spam or delivered to a junk-mail folder. Aka content-based filter.
