Distributed Checksum Clearinghouse 1.3.82 (Default)

Section: Unix

Added: Wed, Jul 11th 2001 10:49 UTC (7 years, 3 months ago)

Updated: Tue, Feb 19th 2008 23:46 UTC (7 months, 21 days ago)

About:
Distributed Checksum Clearinghouse (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.

Release focus: Minor feature enhancements

Changes:
Deal with thrashing problems with large mmap() spaces in recent Linux kernels. Lines in log files for DNSBL hits were changed to include the IP address from the DNSBL. A DNSBL is probed only once for several -B results with distinct SMTP 4yz or 5yz rejection messages.
