Distributed Checksum Clearinghouse, in short DCC, is a system of clients and servers that collect and count checksums related to mail messages. The counts can be used by SMTP servers and mail user agents to detect and reject bulk mail.

DCC servers can exchange common checksums. The checksums include values that are "fuzzy", or constant across common variations in bulk messages.

What's New in This Release:
Optionally in dccm, and by default in dccifd in proxy mode, this release will temporarily reject SMTP recipients that might be forced to have spam discarded instead of rejected because it must be delivered to other recipients.
/var/dcc/libexec/updatedcc should automagically fetch, build, and install this version, unless you have installed a version of Linux with the broken default `sort` collating sequence since last upgrading.
If so, an easy way to get the old updatedcc script working is to delete the entire /var/dcc/build/dcc directory before running updatedcc.
