If you have a connector behind Exchange (example: linux or other sendmail) you can set up the permission on the connector. If you don't have connector you can run the SMTPREG.VBS (you can find it on MS site) and write your own EVENT_SINK vbs code. You can find more information about writing EVENT_SINK handler on Exchange Platform SDK.
