DSPAM v3.0 RC1 Spam Filter Released

Posted by simoniker on from the egg-and-beans dept.

Nuclear Elephant writes "DSPAM v3.0 RC1 is now available for download, with a stable release scheduled for June 13. DSPAM has appeared on Slashdot and in Wired News in the past for its high levels of accurate spam filtering. v3.0 is the product of three solid months of work. Some of the highlights include a very sleek redesigned interface, PostgreSQL support, many mathematical enhancements, and support for many of Gary Robinson's algorithms (such as Chi-Square, Geometric Mean Test, and Robinson's technique for combining P-Values)."

  1. Innovation - Statistical Hybrid Filter by ospirata · · Score: 4, Insightful

    DSPAM has a strong focus on providing better data to already existing algorithms (Bayesian, Chi-Square, etcetera) Combination algorithms work inherently well, but depend on the quality of data. Some of the approaches deployed in DSPAM towards this goal include Chained Tokens, Inoculation Groups, Classification Groups, advanced de-obfuscation techniques, and a new noise reduction algorithm called Bayesian Noise Reduction. The goal is to incorporate processing algorithms that can withstand the long haul of ever increasing message complexity. So far we're doing a great job.

    The idea of combining more than one anti-spam heuristic is not new. But one thing that cant be denied is that all methods are just complementar to Bayesian analysis, that can reach up to 95% precision by itself. Chi-Square, itself, can reach up to 85% precision

  2. Yay, we fixed spam! by Anonymous Coward · · Score: 5, Insightful

    Look! We came out with this great filter so nobody else gets spam! This solves the problem of spam once and for all! Even though spam is still clogging our networks and wasting bandwidth, this filter will solve all of our problems.

    With all the time spent on making spam filters, why don't we spend that time working out a new protocol for email transfers, one that would not be able to spoofed, or spend that time installing server side programs that put a small time delay between messages as well as bandwidth restrictions for all outgoing mail?

  3. Spam is in our culture to stay by Jotaigna · · Score: 4, Insightful

    unless mail sending protocol is redesigned(for example,in a way you have to have your fingerprints recognized when you type it) we will have to face the fact SPAM will be in our daily news. Soon slashdot will put an article where the best 3 spam filters are compared, like a normal review.

  4. Is it easy to setup? by Trashman · · Score: 4, Insightful

    I tried to setup spamassasin a couple of months back and I found it to be too much of a hassle to setup. Could someone who used both spamassasin and dspam comment on easy or difficult it is to setup dspam?

    I'm all for throwing technology at the problem, but I hope people still realise that having a complex (and effective) spam filter does not take away the millions of megabits of traffic wasted on UCE when it's in transit.
    If people stop receiving spam, and therefore the morons among us stop giving money to spammers by buying their crap, and thus remove all semblances of profits obtained through spamming, there won't really be much incentive to spam anymore, will there?
  6. a True AntiSpam measure by CodeTRap · · Score: 4, Insightful

    would be to publicly humiliate/boycott the companies that use the spammers services. Like drug dealers, as long as there is a market, the spammers will be around. Remove the demand, and the suppliers will eventually move onto selling something else.

    If you can't kill the leeches because the water is too murky, then boil off the pond!
