DCC will detect how many times certain email has been sended. If its many (thousands) it will have spam points. I recommend using it and Falco&CO could probably add this per user to next version of ISPconfig BUT There is a small problem. I just dont get it to work. I do [FONT="]spamassassin --lint -D and it tells me that its working, but in no DCC on: tests=ALL_TRUSTED,AWL,BAYES_00, NO_REAL_NAME autolearn=ham version=3.1.3 This how its done now: [/FONT] I use joe to edit files.... joe /home/admispconfig/ispconfig/tools/spamassassin/etc/mail/spamassassin/v310.pre edit to enable DCC # DCC - perform DCC message checks. # # DCC is disabled here because it is not open source. See the DCC # license for more details. # loadplugin Mail::SpamAssassin:lugin:CC Exit from editing and install DCC Install DCC - http://www.dcc-servers.net/dcc/source/dcc-dccd.tar.Z Extract the package with tar zxvf dcc-dccd.tar.Z, cd into the directory, and to install type: ./configure; make install SpamAssassin will automatically pick up DCC and use it. DCC uses UDP port 6277 so open your firewall.
