| Summary : Distributed Checksum Clearinghouse
|
Description :
The DCC or Distributed Checksum Clearinghouse is an anti-spam content filter
that runs on a variety of operating systems. As of mid-2006, it involves
millions of users, tens of thousands of clients and more than 250 servers
collecting and counting checksums related to more than 300 million mail
messages on week days. 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.\"
The idea of the DCC is that if mail recipients could compare the mail they
receive, they could recognize unsolicited bulk mail. A DCC server totals
reports of checksums of messages from clients and answers queries about the
total counts for checksums of mail messages. A DCC client reports the checksums
for a mail message to a server and is told the total number of recipients of
mail with each checksum. If one of the totals is higher than a threshold set by
the client and according to local whitelists the message is unsolicited, the
DCC client can log, discard, or reject the message.
