AUH is the system that send emails with upgrade statistics (basically the system tries to upgrade and prepare the patch if possible) and RRS is the system that sends emails reporting upgradable recipes (just those recipes that needs to upgrade). I know, a bit confusing but in your context you are referring to the RRS.
