Previous Recipients in Mail
I know that you can remove "bad" email addresses in the Previous Recipients window. But when I type in an address, the "bad" one still comes up. And when I search for that address in the search bar inside Previous Recipients, it does not show up. And, coincidentally, an address I know I have used many times in the past doesn't even show up in Previous Recipients. Can that database be purged, or rebuilt somehow? Or do I have to delete ALL addresses and start over?
