Yahoo mail account dynamicaly stops accepting incomming


New Email
Hoping someone has seen and fixed this before :
I have followed several threads to repair nothing works. Yahoo, of course, will not answer email.
Wife and I both have Yahoo and Gmail accounts. I get all mail and attachements when testing sends and reverse sends and other computer sends ok. Her yahoo mail account gets this dump:
Delivery to the following recipient failed permanently:
