Hi

I have created a ticket to enhanced this in Camel
https://issues.apache.org/activemq/browse/CAMEL-1234

I have also added a wiki sample with a solution. Albeit not as good as
it will kick in even if the redelivery was a success as long the
redelivery flag is set
But it give the basic idea how to do it.
