How many mail messages does your mail system process each day? A mail system that processes fewer than 100,000 mail messages per day uses less of its own bandwidth and the bandwidth of other DCC servers by using the public DCC servers. (Note that is mail messages instead of addressees.) Each mail message needs a DCC transaction that requires about 100 bytes, and so 100,000 mail messages/day imply about 10 MBytes/day of DCC client-server traffic. Each DCC server needs to exchange "floods" or streams of checksums with 4 other servers. Each flood is currently about 650 MBytes/day for a current total of about 2.6 GBytes/day. When normally installed by the included Makefiles, DCC clients are configured to use the public DCC servers without any additional configuration, except to open firewalls to port 6277. If you do need a DCC server, it should have at least 3 GByte of RAM reserved for the dccd process. 4 GByte is not too much. It should have 4-12 GByte of available disk space.
