Having got SA working at last on my CentOS-7 home server,
I'm thinking of improving its use for me (no-one else).
It's finding about 65% of my spam, and I'd like to increase that to 80%.
The best way to quickly cut spam is to add the zen.spamhaus.org
blacklist to your MTA.
http://www.spamhaus.org/zen/
SA will also use some of the Spamhaus blacklists for scoring, but Zen
is good enough to put in your MTA and simply reject anything that
matches. Zen rejects about 70% of the spam that comes to my server
without ever getting SA involved.
In addition to RBLs, there's several public rulesets available outside
the sa-update channels you can use which can be more aggressive or broad
than SA is by default.
I am one of the maintainers for KAM.cf which you can always get the
latest of here: http://www.pccc.com/downloads/SpamAssassin/contrib/KAM.cf
There's at least one other I remember that someone on list runs, but I
am completely blanking on the URL at the moment.
