EXPÉDITEUR EXTERNE: Ne cliquez sur aucun lien et n’ouvrez aucune pièce jointe à moins qu’ils ne proviennent d’un expéditeur fiable, ou que vous ayez l'assurance que le contenu provient d'une source sûre. If, after the messages expire, you connect a real consumer to the topic, does it receive those messages or does the broker expire them at that point? How are you setting the expiration time on these messages? For the web console, are you saying that this particular topic's enqueue counts (on the Topics tab of the web console) aren't increasing when you publish these messages?

Dead letter queue is only for queue?
