All day long I was screwing around with ChatGPT to get my spamassassin filters working, and it turns out it made a mistake early on and it never caught it no matter how many ways I let it give me debug statements. Finally I decided to trace it by commenting out one line at a time until I realized certain rules will never be evaluated if you set its score to zero, when Chat assured me early on (several days ago) that this was a valid mechanism. I changed the score from 0 to 0.001 and everything finally works perfectly.
