This can be interpreted in two ways. One of it is the normal way:
Accept everything from local LAN unauthenticated and from the outside
only if authenticated. This can trivially be done by enabling
authentication and putting the local LAN into dc_relay_nets in
/etc/exim/update-exim4.conf.conf.
The other possible interpretation, _never_ accept from the outside and
require authentication from the inside cannot be done without
modifying the rcpt ACL that comes with the Debian exim packages.

That's the default, Debian's exim packages don't have exim advertise
authentication over unencrypted connections.

That's something you'll have to do manually in the ACLs as well.
