A method often employed by antispam software to filter spam using criteria established in a centralized rule database (Every e-mail message is given a rank, based on its header and contents, which is then matched against preset thresholds. A message that surpasses the threshold will be flagged as spam and discarded, returned to its sender or put in a spam directory for further review by the intended recipient)
