- i do not receive any email from "this" friend

i want to check if, by any chance, "his" address is in
"the forbidden senders" list

how to please ?
thanks in advance -

Who still uses Yahoo? Change to gmail.

With the .com version of Yahoo mail, open the Settings menu at the top of the page, and then click on the Notifications (or Manage Blocked Notifications) link.

thanks for your answer - - -
't would be too long to explain why i'm keeping such a mail.yahoo.co.jp account
of course i'm using gmail for my normal life ;-)

i need to see the japanese for (here are google translations) "Settings menu" (設定 ???), "Notifications" (通知 ???) or "Manage Blocked Notifications" (ブロックされた通知を管理する ???)
