Auto add reciepents in yahoo app
The "STOP" auto add recipients I was referring to was in the yahoo mail app. Your response was to yahoo mail in a browser. It seems like the yahoo mail in the browser would or should sync the settings from the browser to the yahoo mail app. The yahoo mail app is what has added thousands of people I have emailed or replied to in an email. I want to stop this function in the app itself and there is not a way to do that.
I manage several Yahoo accounts, and contacts from other accounts show up in my own. I have not synched with another device, and I REALLY only want my only own address book entries to show up - and not those off any email I've ever sent!
