Hi xoAlto,

EDIT 4/13/2011: The helpdesk should no longer process it’s own system notifications. If you have already implemented the “CC RegExp” workaround for pre 5.0 installs, please remove it and download the latest version of the application here .

For any email addresses you want to ensure do not get processed by the helpdesk, go to Settings → Email Settings → Advanced Options → CC Email Filter.
