This sounds like you have not configured the local Exim server to accept
mail for the domain you are sending to. If you are using the default
exim conf file, there is a domain list called "local_domains" which
needs to have all the local domains added to it. If it is relaying for
certain domains, they need to be added to "relay_to_domains".
If it's just some random email address out there on the wild wild
internet, you probably need to authenticate or add your local, internal,
_trusted_ network to the "relay_from_hosts" list.
If you're using the debian split config, please check your documentation
on the correct mailing list to seek help as there is only one person on
this list that knows much about it and he'll probably answer your
question and tell you to look at the documentation regarding the correct
list :P

Only if you trust 10.x.x.x and there is no way for outside sources to
pretend to be from that network, you can add it to the
"relay_from_hosts" list. However, you are probably better off setting up
authentication for message submission.
