I spent a few hours last night to set up dspam spam filter on my mail server. I previously ran spamassassin, and was quite satisfied with its results, but it needs too many ressources (especially RAM).

I thus build some backports for Sarge, available in my repository (these are not (yet) on backports.org). I integrated dspam as a content filter for postfix with the MySQL driver, mixing various how-to’s. I chose to use a shared global group so that all my users share the same datas (similarly to my previous configuration with amavisd-new and spamassassin).

For the moment, it is not possible to tell if dspam is more efficient than spamassassin, but I can easily assert it is far more light in terms of ressources. As a proof, here is my MRTG graph for RAM usage a few hours after switching from SA to dspam:

Now I need to figure out how I can make mailgraph work with this setup, as dspam does not send its messages to syslog, but they are relayed by Postfix.

Note that I haven’t tried to set up dspam Control Center.

I will surely write a small article on my setup on kirya.net.
