Subject Re: How to enrich with recipient list?
Date Wed, 02 Apr 2014 06:33:14 GMT
Hi

You should then use the content enricher EIP if  you want to merge the
current body with the enriched body.

http://camel.apache.org/content-enricher.html

Though the content enricher does not support dynamic uri, as the
recipient list does.
