Spamassassin – Bayesian autolearn

Just noticed the Spam Assassin auto learn rules. Look up perldoc Mail::SpamAssassin::Conf and search for auto_learn, auto_learn_threshold_nonspam, auto_learn_threshold_spam.
I’ve changed the auto_spam threshold down, as 15 is probably a bit high considering the small number of false positives I usually get.

New SpamAssassin Out!

Version 2.55 of SA is out. The release notes are a bit terse, but the notes for 2.54 indicate this is a release worth installing. It adjusts some spam rules spammers were using to get past SA!

spammers have been targeting our nice rules to get themselves negative overall scores, so those rules are now much less strongly-scored. also added a “TOO_MANY_MUA” rule that will catch multiple user agent headers.

Go download it now!

SpamAssassin

Yet another release of SpamAssassin is out. Spam is definetly getting harder to track. I got one this afternoon that simply asked me to click on a url. How can you defend against that? Maybe the tmda folks have a point..

SpamAssassin 2.51

Note to self, install this at work on Monday: SpamAssassin 2.51 (via Dangerous Meta)
Over the last few days a lot more spam has got through to my inbox, and it seems to be after I installed version 2.50 of SA. This could be because I was still training the Bayesian filters. I also blacklisted *@artist-server.com as they were very persistent in spamming me. That helped, and putting the threshold down to 4.5 caught 2-3 spams. Today was better. Perhaps the Bayesian filters are working now!
On another related matter, I configured Goldmine to filter out spam, but it’s unusable. Goldmine has to create a new identity for each new email address so it’s easier to delete the email “online” before it’s downloaded. (If you knew Goldmine you’d know what I mean, it sucks!)

SpamAssassin – web based Bayesian training?

The latest release of SpamAssassin has support for Bayesian analysis. You have to train it and it gets better.
The only problem is SpamAssassin uses a command line app, sa-learn, to learn about your mail. Who’ll volunteer to create a web-based form to copy and paste spam/legitimate mail to train it? Adding an “upload file” button would be great too to for those mass-mail learning situations when you come into work in the morning..
It should be easy enough, although you’ll have to use su-exec or something to add rules to different user’s accounts. So, who’s up for it then?

On Qmail:
Valen had admitted to having hacked QMail to support Oracle DB Backend while working for a prominent Irish company..
<Valen> Why do I get the shit jobs ? I think I preferred cleaning autopsy tables more than hacking qmail.
