Decided to leave an early Christmas present here for everyone I have an updated list of SpamAssassin rules I've been analyzing and running with for the past few months. According to my data (and helpful analysis from ChatGPT), this gives me about a 97% accuracy rate in my own mailbox at least. The remaining percentage was mostly from Bayesian learning rather than any particular score that could change the results, so running more spam training seemed to help smooth it out after a while.
A kind reminder... your mileage may vary as this is tested only with the spam that myself and other users on my Cloudron instance tend to receive, so it may not be as effective on your own mailboxes, but this should definitely help improve accuracy on spam detection especially for those who aren't yet using any tweaked SpamAssassin rules. Enjoy.
Oh and remember to replace {redacted} with your own API key for Abusix if you are using Abusix like I am. If you're not, then just remove or comment-out those lines from the rules below.
