Exim - Unrouteable Address

I need assistance with using Exim as an SMTP emulator.  I have been all over Google trying to find the answer, but I can't quite find it.

When I run the command of exim -d -bt user@email.com, I get this:
Please note: user@email.com is not the real email address being tested. I made this up only for example purposes

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Testing user@email.com
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
Considering user@email.com
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
routing user@email.com
--------> dnslookup router <--------
local_part=user@email.com
checking domains
email.com in "@bc1.la.int"? no (end of list)
email.com in "! +local_domains"? yes (end of list)
calling dnslookup router
dnslookup router called for user@email.com
  domain = user@email.com
DNS lookup of email.com (MX) gave NO_DATA
returning DNS_NODATA
DNS lookup of email.com (AAAA) gave NO_DATA
returning DNS_NODATA
DNS lookup of email.com(A) gave NO_DATA
returning DNS_NODATA
dnslookup router declined for user@email.com
"more" is false: skipping remaining routers
no more routers
user@email.com is undeliverable: Unrouteable address

"DNS lookup of email.com (MX) gave NO_DATA"

The local resolver on that exim server can't get the MX record. Is this your domain or someone elses? If yours, is it loaded in local DNS as well as external?

For grins, try changing the local resolver to something public like googles 8.8.8.8 and doing the test again. The nameserver can be set in the /etc/resolv.conf file

The server is on a subdomain of the mail domain of where, in this example, is email.com

I don't see a resolv.conf file.

In my etc directory, all i have for config files is just exim.conf

Oops. I meant to say:
The server is on a subdomain of the MAIN domain of where, in this example, is email.com

I'm talking about the /etc folder for the whole system, not just for exim. What OS is this system running?

klewis94Author Commented:
It is Server 2003.

OK. Got it. I need to modify the system's host file then?

jar3817Commented:
Huh? Exim is linux/unix software, how are you running on server 2003?

klewis94Author Commented:
No. You can install and run Exim on a Windows environment using what is called Cygwin for Windows.
http://www.cygwin.com/

That is what I am using.

jar3817Commented:
Ok, now I understand what you meant by "SMTP emulator"....

I'm familiar with Cygwin, but never actually used it. Does it inherit the DNS settings from windows or do you specify the settings internally?

klewis94Author Commented:
You specify it in the exim.conf file.

But, that's the problem I am having.

If I attempt to send an email to any other email domain it works fine. If I attempt to send the email to my own domain, this it doesn't work.

So, I believe it is something in the exim.conf file.

Try changing the DNS to something public like 8.8.8.8 and try again. I have a feeling it's an internal/external DNS issue. If you don't have your domain setup properly internally it won't work, but outside servers can send to you because you probably have it setup externally correctly.
