Abstract:
1. A computer implemented method for evaluating electronic mail messages, comprising the steps of: identifying an electronic mail message from a particular sender as spam; determining whether the particular sender of the electronic mail message identified as spam is stored in a database comprising: reading from the database the current reliability value associated with the electronic mail address of the particular sender stored in the database; determining whether the current reliability value associated with the electronic mail address of the particular sender is greater than a predefined threshold; calculating a new reliability value for the electronic mail address of the particular sender by decreasing the particular sender's current reliability value in response to the determination that the current reliability value associated with the particular sender is greater than a predefined threshold; and changing the identification of the electronic mail message to not spam in response to the determination that the current reliability value associated with the particular sender is greater than the predefined threshold.
