Harald, How would you propose that AFTER_HEADER be pre-emted. I can follow how the other hooks would work, but the after header one would have to be called when DATA command is issued. Otherwise how would you know when ALL the header commands were sent. You would not be able to terminate/reject/et before DATA, only an abrupt termination of the session. Comments???
