I've got two questions.
If I have message delivery confirmation on will it show as delivered if the person using an iPhone has blocked me?
Also what does Error code:Addr.vacant. mean when a message has been sent and delivered which had delivery confirmation off and sent in another app?
The messages I checked which had that I had sent with Facebook Messenger.

To confirm, was the error code associated with Facebook Messenger?
