[Exim] exim is open relay when started via xinetd

Greetings.

Starting exim (3.34) via xinetd (2.3.3) with default exim.conf ends up
being an open relay.

Here is the xinet.d/exim

service smtp
{
   socket_type = stream
   protocol = tcp
   wait     = no
   user     = mail
   group    = mail
   server      = /usr/sbin/exim
   server_args = -bs
   per_source  = 8
   log_type = FILE /var/log/xinetd/exim
   log_on_success = PID HOST USERID EXIT DURATION
   log_on_failure = USERID ATTEMPT
}

Seems that with "-bs" option, exim treats ALL mail as local,
and trusts the sender.

Is this a known issue? Am i doing something wrong?

Kind Regards,
