Wolfgang I am not really involved in development of MboxIterator, but generally you should be able to find sources in the ASF source repository [1] or at github [2] (read-only copy of the official repo). Once you have a change-set which you would like incorporated in the official code tree, you should raise a change request in JIRA [3] and attach the patch to it or reference a pull request at github.
