I also noticed this a few weeks ago. I have 7 employees with "Account level filtering" set to send spam to trash folder. Filter is "Spam Status begins with Yes, deliver to Trash". For the past 2 years our main trash folder would get 250-350 spams per day, I'd dump approx. 2000 per week. A few weeks ago each employee started getting an extra 25-50 spams per day, our trash folder at cPanel now gets zero. I did not change any settings, but I did notice a new cPanel "look". Something changed!
