Processing rules are accompanied by Pre-processing and Post-processing rules. Like Processing rules, they apply only when opening a folder, but like Filtering rules, they are shared accross all folders. You can configure them from the Tools menu. Pre-processing rules are executed before the folder's specific Processing rules, while Post-processing rules are executed afterwards.
