In the first section of exim.conf, add:
host_auth_accept_relay = *
auth_always_advertise = false
in the final section, authentication configuration, put:
plain:
driver = plaintext
public_name = PLAIN
server_condition = ${if and {{eq{$2}{USERNAME}}{eq{$3}{PASSWD}}}{yes}{no}}
server_set_id = $2
login:
driver = plaintext
public_name = LOGIN
server_prompts = "Username:: : Password::"
server_condition = ${if and {{eq{$1}{USERNAME}}{eq{$2}{PASSWORD}}}{yes}{no}}
server_set_id = $1
now, any machine on the internet can send mail through your SMTP server,
but only if it authenticates using USERNAME/PASSWORD. You can make these
whatever you want. The example above gives a global user/pass that
_anyone_ can use. I find that to be sufficient for a small group. You
can do more elaborate things with exim's database lookup capabilities.
Also, you might run into the problem where some ISPs disallow outgoing
connections to port 25 in order to stop spammers. I'm pretty sure
earthlink does this. If your boss connects from one of these networks,
he won't be able to send mail. To handle that, I use NAT on the server
to redirect connections to an unused port (like 24) to 25, then
configure clients to connect to port 24.
