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. >And the connection must use TLS. That's the default, Debian's exim packages don't have exim advertise authentication over unencrypted connections. >There should be a message size limit based on the username received >during authentication, e.g. user authenticating as "standard" can send >messages up to 1MB, while user "privileged" can send up to 5MB. That's something you'll have to do manually in the ACLs as well. Greetings Marc -- -------------------------------------- !!
