The client that consumed those messages could issue the basic.recover
method to return all unacknowledged messages to the queue, taking care
to do so on the same channel that the messages were consumed on:

http://www.rabbitmq.com/amqp-0-9-1-quickref.html#basic.recover

Or The client could use basic.reject to return individual messages back
to the queue:

http://www.rabbitmq.com/amqp-0-9-1-quickref.html#basic.reject

The client could also use basic.nack to send a range of messages or
individual back to the queue:

http://www.rabbitmq.com/nack.html
http://www.rabbitmq.com/amqp-0-9-1-quickref.html#basic.nack

Another way of returning all unacknowledged messages to the queue is to
close the channel.
