Yahoo Mail cannot send or receive emails
Yahoo Mail cannot send or receive emails. Incoming messages are rejected with SMTP error 552 5.2.2 “mailbox full”, although storage shows only 7.4 GB used and the app shows 7.43 GB of 1 TB with 99% available. I already reduced storage from about 10 GB to 7.4 GB and emptied Trash. Please investigate the mailbox quota/provisioning status on the server side.
