Blocked and allowed phrases
You can add to the list of blocked phrases the expressions, which you typically observe in spam, and define the weighting coefficient for each phrase. Weighting coefficient allows you to specify how typical a certain phrase can be for spam messages: the larger the value, the higher the probability that mail containing such phrase is spam. Weighting coefficient of a phrase can range from 0 to 100. If the total of weighting coefficients of all phrases found in a message exceeds 100, such mail will be recognized as spam.
