Subject: [Exim] Faq Q0301 for dummies?

I have a linux machine (192.168.1.4) on my lan that runs exim. I have
an OpenBSD machine (192.168.1.1) that serves as a router to the internet
via a connection to my ISP.

My ISP's smtp-server has been getting really flaky lately, so I decided to
try using exim on the linux machine as an SMTP server for my LAN.

So if in pine (on the linux box running Exim) I set the smtp server to be
"localhost" (192.168.1.4) and I try to send a message to anywhere, The
message gets frozen with the following text:

--
Message 15PRzk-0002KY-00 has been frozen. The sender is
<jeffm@???>.

The following address(es) have yet to be delivered:
jeffm@???: remote host address is the local host
--


In this example, I've tried sending a message to my own address, which is
hosted somewhere far, far away. boxybutgood.com is definitely not the
local host. I can try sending messages to any other address as well, and
I get the same problem.

Here's what the entry in /var/log/exim/mainlog looks like....

Q0301(A) doesn't seem to be the problem, as these hosts are definitely not
local domains.

Q0301(B) doesn't seem to be the problem... If I understand the FAQ
correctly, I'd have to set up a rule for each domain I wanted to send mail
to.

Q0301(C) might be the problem, but I wouldn't know how to check. I'm not
running my own DNS server, and my ISP's DNS server has posed no problems
before with any other network app, including when I used to use sendmail
to do this stuff.

For some reason, I think this section of my configuration file might be
the problem...

# Send all mail to a smarthost

smarthost:
driver = domainlist
transport = remote_smtp
route_list = "* localhost bydns_a"

end

Is my hunch correct? If so, how should I fix it?

Can anyone provide me with a clue? :)

Thanks!
