Is there a way to see if a person's server I'm messaging is not communicating with our server or blocked?

Few people I msg said we can't see each other's msg / someone is blocking which is ok as long as I know at the time trying... instead of sending message and waiting a looooog time (msg will never reach them)! :)

Like a colour highlight or message to say "This person won't get your direct message as one of you is blocking" or similar.

Does something or some way exist?
