I have read every post I could find regarding DSBL and Charlie's mailfront contrib.  I have installed mailfront and Darrel's DSBL tarball.  I have added a bunch of RBL's to /var/server/smtpfront-qmail/rblsmtpd.conf.  After a week the logs are reporting that DSBL has blocked 0 messages.  I have checked the spam getting to my inbox and most of it is on one of the RBL's so I am sure that the mail is never being checked.
I am running V5.6 with Spamassassin installed and working perfectly.  I am trying to get mailfront working to block the spam before making it to procmail.  
Any ideas to get mailfront working?
