You can use loop : http://camel.apache.org/loop.html

<route>
  <setHeader headerName="smsRecivers">
     <simple>{{reciversList}}</simple>
  </setHeader>
  <loop>
    <simple>${in.header.smsRecivers.size}</simple>
    .....
  </loop>
</route>

Inside loop body you can get list's item by index, using excange property CamelLoopIndex or you can use custom increment index ( which can calculate in other header ).
