Exim 4.34 Config issue "Sender domain must exist"

I am trying to setup a web server running Debian "Sarge" and Exim
4.34. After much research and even more trial and error, I think I
figured out the configuration scheme Debian uses for Exim 4. The
problem is when I try to have send email through a web feedback form,
the message is undeliverable. I get the following message back:

================================================== ==============================

Question: What do I need to do in order to inform Exim of the sender's
domain? I have checked Google, but nothing I've found seems to help.
Do I need to setup DNS on my system or is there an easier solution?

Thanks.

I may be wrong here, but this is how I interpret the situation, based
on some DNS lookups.

The error is from the remote mailer, which is lorman.alcorn.edu
[209.147.192.4]; it's issuing a message:
501 <root@rivendell.alcorn.edu>... Sender domain must exist
telling you that a DNS lookup of the sending machine's name fails.

It fails here, too. When I try to look up rivendell.alcorn.edu, I get
this:

:1 $dig rivendell.alcorn.edu
:1 ; <<>> DiG 8.3 <<>> rivendell.alcorn.edu
:1 ;; res options: init recurs defnam dnsrch
:1 ;; got answer:
:1 ;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 2

Maybe the DNS maintainer at alcorn.edu needs to add rivendell to his
zonefile? Try mail to sia@alcorn.edu.

That sounds plausible. Same thought ran through my mind, but I wasn't
sure. Thanks for the input. I'll let you know if it works. :)

Sure.

Configure fetchmail correctly to poll the external pop3 server. Each
mail it has downloaded is passed to the local mta (exim) via localhost
port 25.
In addition, your exim needs to be configured in a way that local
users can receive emails.

On the web, you'll find tons of information about how to create a
syntactically correct ~/.fetchmailrc; and maybe your exim has already
been setup in the right way by debconf.
Otherwise, exim documentation can easily be found via
<http://www.exim.org>.

Christian
