DSPAM v3.2 Released
Nuclear Elephant writes "After four months of development DSPAM v3.2 has been released, bringing many new enhancements and filtering technologies. These include distributed computing support, implementation of Bill Yerazunis' Sparse Binary Polynomial Hashing algorithm (from CRM114), and v1.2 of Bayesian Noise Reduction. Other enhancements include SQLite support and many significant performance enhancements for PostgreSQL. DSPAM's official release is next week, but you can download the preview release now. Users of the project have also contributed towards creating a new logo for this release."
Here's what it shows.
ONLY the 3.2 Preview Release 1 is currently out!

This is a legit message from someones mail system. You are receiving this because someone has been infected with a virus. Their computer is sending messages from your email address, and some of these messages are going to non-existant mail addresses. Because they are spoofing your mail address in the From: you are receiving all the bounces.
So technically, this isnt spam or junk mail. Its someones email system doing what its supposed to, returning 'your' email because the sender didnt exist.
Unfortunately, probably not much you can do about this without blocking all such legit system messages.
It's your server and hopefully you'll never have to suffer the 'collateral damage' of living near a spammer (network neighbourhood wise). It has happened to me a couple of times. The first time I actually spent time sending my reply from my gmail account, and told the guy about it. The second time I didn't even bother.
Netblock blacklisting is a really poor solution. In some cases a single spammer causes a /24 and then a /16 to be blocked. It doesn't make sense to me. OTOH, I discovered some time ago that blocking Windows boxes works wonderfully, and it's extremely easy to do with OpenBSD's pf :-)
Btw, do you understand that changing ISP may not be an option?
Why does DSPAM get front page treatment when the latest POPFile release (which now handles POP3, IMAP, SMTP and NNTP filtering) and has an XML-RPC external interface, supports different databases, etc. etc. gets rejected as a story?
/. has recently turned into some combination of Freshmeat and PC Magazine? Yes.
Perhaps it's because I don't tend to make super-wild claims about POPFile's accuracy? Or come up with cool marketing names for the internal technology?
POPFile's the only Bayesian filter that can:
1. Do more than spam vs. anti-spam and
2. Filter POP3, IMAP, SMTP and NNTP (that's right Usenet news)
Do I have an axe to grind with Jonathan and DSPAM? No, it's a cool project. Does it annoy me that
John.
