To set messages in your Yahoo Mail account to display in your inbox as if they have been read, mark the messages' status as "read" so that the message sender and subject font is un-bolded in your inbox. You can mark individual messages as read even if they have not been opened; or, if you are using one of the new Yahoo Mail themes, you can select all messages in your inbox and then mark all emails as read at one time.
