"The DCC or Distributed Checksum Clearinghouse is currently a system of many clients and more than 150 servers that collects and count checksums related to several million mail messages per day, most as seen by Internet Service Providers. The counts can be used by SMTP servers and mail user agents to detect and reject or filter spam or unsolicited bulk mail. DCC servers exchange or "flood" common checksums. The checksums include values that are constant across common variations in bulk messages, including "personalizations."" Already-packaged SpamAssassin can exploit DCC, too. -- Juhapekka "naula" Tolvanen * http colon slash slash iki dot fi slash juhtolv "tänään tuuli kantaa pölyä, kullankeltaista, murheenkeveää. tänään tuuli kantaa nimeä, huulille katkeraa. tänään tuuli kantaa pölyä, hopeaista, heilimöivää. tänään tuuli kantaa nimeä, huulille taivaanmakeaa."
