The Distributed Checksum Clearinghouses or DCC is an anti-spam content
|
|
|
|
|
filter that runs on a variety of operating systems. 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."
