Right,
someone from outside the LAN is trying to send e-mail.
We control the domain from inside the lLAN
but exim is rejecting the e-mail because it is originating
from outside the LAN.

Now is the time time to declare your allegiance!
This means that you will need to setup authentication parameters in your
configuration file. Then, those that are trying to connect will have to
ensure
they set the "My Server Requires Authentication" (or something like that) in
their e-mail clients. That way when they attempt to send a message, the
e-mail
client will know it needs to send authentication information before the
message
can be sent.
In my Exim configuration file, I have this:
accept
authenticated = *
Then at the bottom of the config file (in my case), you'll need to specify your
authentication techniques:
begin authenticators
plain:
driver = plaintext
public_name = PLAIN
server_set_id = $2
server_condition = <condition here>
server_advertise_condition = true
login:
driver = plaintext
public_name = LOGIN
server_prompts = "Username:: : Password::"
server_condition = <condition here>
server_set_id = $1
server_advertise_condition = true

it depends on them entering a proper username/password to authenticate.
