DSPAM is a server-side statistical anti-spam agent for Unix email servers. It masquerades as the email server's local delivery agent and effectively filters spam using a combination of de-obfuscation techniques, specialized algorithms, and statistical analysis. The result is an administratively maintenance-free, self-learning anti-spam tool. DSPAM has yielded real-world success rates beyond 99.9% accuracy with less than a 0.01% chance of false positives.

Cpanel support?
I spent some time on the nuclearelephant site, reading the FAQ and the Readme, as well as exploring.
I had a question that I could not find answered and didn't see any forums, maybe I missed them.
As your FAQ noted, SA is out of date and being circumvented to an alarming degree. My server is a shared server running the Cpanel suite and I was looking for an "installation for dummies" type checklist. (Sorry I am what I am.)
I can FTP the files up and create a MySQL database with users and assign permissions, but I am a little lost at a lot of the other cmd line functions. Does a step by step install for this type of environment exist?
Thanks for your patience.

Hi! Have you checked the doc/ directory, which is full of
documentation for various types of integration, or the very
elaborate README? How about the online FAQ, or the many
links to HOWTOs on the website?
Can't make heads or tails
The documentation for dspam is almost non-existant. How frustrating. I had to make sense of things from the usergroups.
3.1.2 is a recommended upgrade, especially with pgsql
I have upgraded to every 3.1.x release, and am by far the happiest with 3.1.2. They fixed a bunch of stuff, especially concerning the postgresql backend.
My false positive rate has plumetted.
