I am running a mail server which suffered of assigning too high spam scores based on DNS_FROM_AHBL_RHSBL.
The Abusive Host Blocking List is not functional anymore and resturns a postive on every request. This adds 2.7 point to the spam score count by default. On a treshold of 5 that is a lot.
For some reason, spamassassin updates do not exclude DNS_FROM_AHBL_RHSBL from the spam score.
The general recommendation on Google is to add this line to /etc/spamassassin/local.cf:
Code:
score DNS_FROM_AHBL_RHSBL 0
What I found confusing is that the score is not in this file by default. It is buried somewhere deep down a configuration directory (/usr/share/spamassassin/...) in some file which is autogenerated.
Long story short, to eliminate this parameter, you have to
add this line to /etc/spamassissin/local.cf. Even if the line isn't there.
I hope this information helps someone else.
