For years spamassassin version 3.3.1 (spamd -c -d) running on Perl
version 5.10.1 on our Slackware server kernel 2.6.39.1 has given
good service but just lately it is letting thru a lot of "junk
enhancement" rubbish and other rubbish despite me running sa-learn
and sa-update hopefully teaching spamassassin what to ignore.
Please tell me where I start to resolve this issue?
Besides the obvious which is upgrade to latest (currently trunk), Are
you using any RBL's? Any custom rulesets?
I do not understand RBL. Please explain.
No custom rulesets.
RBLs, which there are some by default in SA unless your volume is too
high or you disabled them, are ways of blocking spams different than
content analysis. See
http://en.wikipedia.org/wiki/RBL_%28Internet%29#History_of_DNSBLs
They are a crucial part of an effective system for blocking spam and you
should research them more.
You might also research more rule sets. For example, I write one at
www.pccc.com/downloads/SpamAssassin/contrib/KAM.cf which you can use at
your own risk, etc. I, personally, think of SA as a project whose
primary goal is to release code that allows a framework for combating
spam. Our secondary goal is to release rules. Our third is to provide
resources to block spam. These are my own personal approach because
writing rules that are then judged outside of my environment is too
large a hurdle for me to bother with when spam ebbs and flows too quickly.
