How does SpamBox decide if a message is spam or not?
SpamBox (DSPAM) breaks up the entire message content and headers into small parts called “tokens.” It then compares these tokens to the ones in its dictionary of innocent and spam tokens. ITS’s implementation of DSPAM uses the standard Graham-Bayesian and Burton-Bayesian algorithms for determining the probability that a message is spam, based on the tokens of which it is made up.
