Description

We use Apache Camel, in particular its IMAP and SMTP endpoins. When, for whatever reason, the endpoints fail, e.g. the SMTP server is down, then it was nice if we were able to connect to an alternative endpoint. As I have researched so far, Apache Camel does not allow for a dynamic way of specifying the URIs e.g. in terms of a user supplied callback Strategy. The only way I have figured out are the load balancing features, but then you still have to know the URIs in advance.

So may I suggest to add overloads of the from() and to() methods that accept expressions, which in my opinion would gain the flexibility desired?
