Determining whether a number of electronic messages of the subset of electronic messages directed to the single recipient and obtained within a pre-defined time interval exceeds a threshold; and
Discarding the electronic messages of the subset of electronic messages if the number of electronic messages of the subset of electronic messages directed to the single recipient and obtained within the pre-defined time interval exceeds the threshold.
