Both settings exist, but you are right, my setting is deprecated:

The downside was there is no way to exclude a specific folder (such as a junk mail folder). However, that setting was replaced in version 5.0 with server-specific ones. Set mail.server.default.check_all_folders_for_new to true instead to make it effective for all accounts using the Config Editor.
