Because that's a more secure standpoint to take by default. Can you
imagine what it would be like if every mailserver was set up to be an
open relay? Many people who install linux systems don't bother (or even
know how) to disable relaying (just as you can't seem to ENable it).
It's much safer to have people in your category (not able to relay
selectively) than people in the other category (running an open relay,
and probably not even knowing it).

To enable relaying for certain hosts in exim, look at the configuration
option host_accept_relay. Mine (the default) looks like this:

# The setting below allows your host to be used as a mail relay only by
# localhost: it locks out the use of your host as a mail relay by any
# other host. See the section of the manual entitled "Control of
# relaying"
# for more info.

host_accept_relay = 127.0.0.1 : ::::1

Huh! look at that ... it even includes a pointer on where to go for more
help!

Sorry, I don't mean to be such a smartass.

You should just be able to add the IP address of the host you want to
accept mail from to that line. Note that you might be able to get a
bette (slightly more secure) setup by looking into SMTP auth
capabilities (the next statement in the exim.conf file). I'm not sure
how well OE supports it, though, and if set up incorrectly, it will
yield a *LESS* secure environment (cleartext passwords being thrown
around are a Bad Thing).

HTH. Feel free to post any followup questions if you're still having
troubles.
