I’ve been getting a ton of CBD expo spam for months. Spamassassin picks up most of it, and Gmail collects the rest in the Spam folder. However, today one got through so I scrolled down to the unsub link and saw it was sendgrid. I recognise them from previously reporting […]
Why not let Google filter your spam?
I’ve been running Spamassassin and Postgrey on my mail server for the past few months. It was only since the server was upgraded that I had enough juice to run the very intensive SA processes (even using spamd), but still on occasion the server would grind to a stop when […]
Filter spam through Postfix and Spamassassin
It has been a long time since I used and configured Sendmail, and I don’t miss it one bit now that Postfix is on the scene, but the amount of spam I receive does bother me. My Junk folder had reached 160MB, mostly due to some idiots sending huge spam […]
Thank you SpamAssassin, again!
Every Monday morning it’s the same. There’s a pile of spam and it numbers in the hundreds of emails. Thankfully almost all of it was caught by SpamAssassin. So, for those of you interested: Regular email: 1.3MB Spam email: 4.2MB Total spam: 507 emails. Spam that auto-trained: 400. Spam to […]
Spamassassin – scoring on DSL lines
Since upgrading to Spamassassin 2.60 yesterday I’ve noticed a (small) increase in false positives. There were only 4 out of 132 spams caught overnight, but almost all were from dsl or dynamic IP addresses. The default score for this test is 2.5, but if you add the following to /etc/mail/spamassassin/local.cf […]
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, […]
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..
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 […]
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 […]
