Is there a way I can load a Blacklist database on spamassassin or use a URI server check? I got the strength level setup at a level that legit emails are passing with no problem, if I increase strength, legit emails becomes spam. I receive a lot of spam and a lot of them are still passing thru spamassasin as legit emails. I found this website with blacklist database and it shows how to setup on spamassassin. http://www.sa-blacklist.stearns.org/sa-blacklist/README.howtouse.html I don’t know if this setup will work with ISPConfig 3/spamassassin, Any thoughts on this or how can I make my spamassassin work more efficiently. Thank you.
ISPConfig uses a simple default spamassassin installation with amavisd, so any tutorial you find should work. What makes me wonder is that spam passes trough your system as my spamassassin default installation catches > 99% of the spam emails. You should check the headers of the emails if there are any negative scores that prevent emails to be marked as spam.
What are your tag-levels on your spamfilter policy, I have changed mine so many times in attempt to get it right that I don't remember what were the default numbers. What will I be looking for in email headers as negative score? Any altaration of file /etc/amavis/conf.d/50-user will affect anything? Thank you.
