> When sending messages to a multicast address to which no consumers are attached, the
router sends back a disposition of RELEASED. The expected behaviour is that all messages will
be immediately settled by the ingress router with a disposition of ACCEPTED as per section
2.4.1 of the Dispatch router book:
> {quote}Multicast delivery is not reliable. If a producer sends an unsettled delivery,
the ingress router shall settle the delivery with ACCEPTED disposition regardless of whether
the message was delivered to any consumers.
> {quote}
> Is this a bug, or is this the expected behaviour? If this is the expected behaviour,
can the router be configured to always accept messages to multicast addresses even where no
consumers are actively listening?
