@frejonb - I think it comes down to how we define which messages can be classified as "delivered". From the broker's perspective, I only consider a message as delivered when the client sends a protocol message indicating ack or nack. By only incrementing the redeliveryCount when a client sends a nack (`CommandRedeliverUnacknowledgedMessages`) protocol message, we ensure that an application sees a message at least `n` times before it gets sent to a DLQ. Otherwise, we're at risk of delivering fewer times than expected. -- This is an automated message from the Apache Git Service.
