Greetings,
I consider myself a "weekend" spam assassin. I run my own server (co-located),
and have about a dozen users (mostly friends and family, but a few paying
customers). But running a mail server isn't my day job. I don't run Razor or
any of the cooperative spam filters simply because I didn't have the time to
figure them out and set them up.
I'm running Spamassassin 3.0.2 which I installed a few months ago.
SA is still only catching about 50-75% of the spam. I've set up Bayes learn
ham/spam mailboxes, and I regularly feed them 200 to 500 messages a day. Yet
even after months of training, I still get messages like this:
Subject: (6/10/05) Mortgage Rate Report
X-Spam-Status: No, score=3.6 required=7.0 tests=BAYES_99,HTML_80_90,
HTML_FONT_TINY,HTML_IMAGE_RATIO_04,HTML_MESSAGE,NORMAL_HTTP_TO_IP,
OPTING_OUT autolearn=no version=3.0.2
As you can see, the Bayes filter has nailed it as spam, but it still only gets
a score of 3.6.
I currently have my threshold set to 7.0. I've been considering lowering it
again (maybe to 5.0), but am paranoid about false positives. I can go through
my mailbox and see ham that has scores of 3 or even 4.
I was hoping that someone here could give me some quick advice as to what I
might be doing wrong, or point me to a trouble-shooting site for SA.
I was previously using a client-side Bayes filtering system and was getting
99.8+% spam identification rates. SA has been, so far, a bit of a
disappointment and I'm sure it's my fault. :)
