How can I prevent the temporary session? Just,only friends can send to the message to me,strangers can’t!

Everyone who can help me？ I have the way to prevent the strangers on the client side which not in friends list. However, is there any way to do on the server side?

There is now way to do this on the server. It’s yours privacy settings and it’s controlled on the client side.
