Optimizing Anti-Spam

[Thom van der Boon]

Hi 

I use 2 things: 



    * Lower threshold: Spamassassin score: 
        * 5: Mark as (possible) spam 
        * 10 (in stead of 15): delete 
    * use KAM.cf: KAM.cf is a very nice set of spammassassin rules file which catches a awfull lot of spam 

You can find the KAM.cf.sh script via Google 

Met vriendelijke groet, Best regards,

Onderwerp: Optimizing Anti-Spam 

Hi all! It’s been years since I’ve implemented something like Mailscanner as part of an anti-spam system, but I’ve used various Linux based systems like Maia Mailguard in the distant past. I've used appliances for quite awhile, but for various reasons have now chosen Mailscanner for the task. Right now I’m training and tweaking things on a smaller subset domain rather than flipping the switch for my entire system. I’ve only been running for about 5 days or so. I’m training the bayes database multiple times a day with both spam and ham, and Spamassassin is now active, but I have a lot of what I consider “obvious” spam leaking through - vulgar words in the subject, sexual content, etc. While my users will forgive marketing and general “junk”, they will be less forgiving of these things ;-) 

I’m doing some research on the best settings to optimize. I used to use things like Razor, DCC, selective greylisting, custom rule sets. I imagine that these things have changed a lot in the past 10 years. Can you give me some ideas on some optimizations you use to tighten things up? 

Thanks!
