    rc.d/sendmail: Return non-zero if the daemon fails to start or is not running
    
    If you have a mail server that is running sendmail daemon
    (sendmail_enable=YES) and sendmail queue runner (sendmail_msp_queue=YES)
    and the sendmail daemon dies, /etc/rc.d/sendmail status does see the
    daemon is not running but returns 0 as the exit code.  This prevents
    other programs (like puppet) from restarting sendmail to fix the issue.
    
    Make sure that the exit code is propagated towards the end of the script
    if any of the sendmail services fail.
    
    This patch does not call exit directly but instead just sets the exit
    status code by calling exit in a subshell. This way we do not exit the
    current shell in case the service script is sourced (e.g., when
    rc_fast_and_loose is active).
