Some exchange types (e.g. fanout) do not use routing keys at all. Are you sure that you need routing

If a message cannot be routed anywhere, there are several options:

 * If it's published as mandatory, it will be returned to the client
 * If there is an alternate exchange specified, it will be tried
 * Finally, the message will be discarded

You need to choose the right exchange type and one of the options above for unroutable messages
according to the topology you want to build. RabbitMQ tutorial demonstrate several very
common scenarios.

Bindings matter during routing. Once a message is routed to one or more queues,
it can be consumed regardless of the routing key.
