I sent email to a friend with a yahoo email acct. Is there a way to tell if my emails are blocked?

We both have yahoo email accounts. If I have been blocked, do I get a notification? Somthing like "this user does not accept email from you"?

yes you will get a bounce email, if you are blocked.
Reply:No you don't receive any notice unless it is an inactive account.
