DCC (Distributed Checksum Clearinghouse)

一直很奇怪我 desktop 用的 Spamihilator detect 到的 dcc score 為何在 server side 的 spamassassin header 沒有。今天詳細檢視 spamihilator 的dcc 設定發覺它多了兩個 public dcc servers:
dcc1.umr.edu
rzsun01.uni-trier.de
在 server 我已加上了，就看看是否多了信有 dcc score.

To check existing dcc server,
#cdcc
cdcc map> info

To add hosts,

cdcc map> add host,[port|-] [RTT+/-#] [ID [passwd]]

RTT stand for Round Trip Time
