  When the address works correctly on locally originating mail, but fails on
mail from elsewhere, always look to see if the sendmail daemon has been killed
and restarted since modifying 'sendmail.cf'.  Otherwise the daemon may still
be using the old configuration.  There is no way to persuade the daemon to
re-read its configuration dynamically.  You have to kill and restart.

  Look in /etc/rc* to find the exact startup command.
