The Central Checksum Service (CCS) is an add-on to XWall and is designed to detect bulk e-mail on a worldwide level. To do this, XWall calculates a checksum of every incoming message and reports it to the CCS server. The CCS server cumulates incoming reports and responds how many message with the same checksum were circulating in the past few hours.
