Block Unknown People from Messenger in Yahoo! Mail

The emails in your Yahoo! Mail inbox are numerous and welcome. When you open it in your browser, the messages are not all you see, though? New instant messages are numerous, too, and totally irrelevant from senders you do not know?

To reduce junk messages coming to Yahoo! Mail by way of its Yahoo! Messenger part, you can set it up to accept IM conversations only from people (and other senders) in your address book.
