There was just a thread about attaching Spamassassin to Sendmail.
I am running postfix. I went through the steps in Kmail of creating the Spamassassin filters as outlined in the Kmail manual.
Is there anything else I need to do, besides doing
sa-learn --spam --dir ~/Mail/Spam/cur/
once in a while. I still appear to be getting a lot of SPAM
Learn how to use Postfix to reject mail based on RBL, unknown hostnames etc. It is far more effective then trying to delete spam after you accepted it. See the postfix site for examples.
Actually, that proves to be largely in-effective for a lot of spam.
Then you've obviously never seen a well configured Postfix server in action against all the hosts that try to deliver their excrements. For me it's stopping about 95% of the attempts (~90 a day), SA is doing the rest.
A great deal of spam gets thru RBLs because it takes several days for these things to trigger, and it also requires VERY careful selection
It's not only RBLs, but it doesn't take long for a new site to get a nice cosy place in bl.spamcop.net.
of which RBL you use, because some of them will list mailservers of large ISP based on a SINGLE report.
That's why there's a 'warn-reject' keyword for the smtpd_*_restrictions, and easy ways to whitelist domains and clients.
The OP was on the right track, Spamassassin is by far the most effective and prudent way to go about this.
SA *is* effective, but stopping the enemy at the gates is better. Theo -- Theo v.
