james-fetchmail.xml contains the following lines at the top:
<!-- See http://james.apache.org/fetchmail_configuration_2_2.html for detailed -->
<!-- configuration instructions and examples. -->
Yet the URL http://james.apache.org/fetchmail_configuration_2_2.html results in a 404, and frankly I couldn't find the page it should be linking to. It would be nice if there would be a correct reference once 2.2.0 is released.
