Install Razor, Pyzor And DCC And Configure SpamAssassin http://www.howtoforge.com/virtual-users-domains-postfix-courier-mysql-squirrelmail-ubuntu-10.04-p3 Hello Falko, I have found your tutorial about enhancing SpamAssasin. If I follow this tutorial to set up Razor, Pyzor and DCC on ISPConfig 3.053, will they conflict with other ISPConfig 3.053 built-in functions? Thank You in advance.
