[rabbitmq-discuss] What does Rabbit do with messages that have been delivered and ack'd

[Mark Petrovic]

I have an application that uses a topic exchange.  If I have N
consumers and each of those ack's the message when it is delivered to
them, Rabbit does not keep a  copy of that message beyond the last
consumer ack'ing it does it?

I ask because I want to know if there are exchange or queue
configurations that I may be inadvertently foisting on Rabbit brokers
that induce them to hold onto messages in its backing db that I
actually no longer care about.

Thanks much.
