I installed spamd and it works well now after the modifications.
The problem I am having is that it is not reading any user_prefs file, nor any local.cf file.
The mail is being scanned with 5.0 as required hits no matter what changes I make in any of the user_pref files. It seems that the default is 5 but I do not know where it is reading it from.
Also, if I stay with ISPconfig's spamassassin rather than spamce, where do I install RulesDuJour? /etc/mail/spamassassin? or under /home/admispconfig/......./spamassassin?
