[Exim] Exim as client smtp auth

Hello,
Sorry for the long post, I needed to include a lot of details.
I am having a heck of a time trying to get client side smtp auth working
with my dial in isp. I am using exim 4.33. I built the binary with both
cram_md5 and plaintext authenticators. Then, I added these authenticators
into the configure file:

cram_md5:
    driver = cram_md5
    public_name = CRAM-MD5
    client_name = jerryvb
    client_secret = xxxxxx

login:
    driver = plaintext
    public_name = LOGIN
    client_send = ": jerryvb@??? : xxxxxxx"

If I send a test message to myself, at jerryvb@???, I get this:
(I login to my local machine as "jerry"; and my machine's hostname is
"lightstar").

jerry@lightstar:~$ exim -v -odf jerryvb@???
From: jerry@???
This is a test message.
.

[216.52.245.18]
LOG: MAIN

Then, if I log in to my isp's web mail, the test message is there. But, if
I try to send a messaage to a remote host, I get this:

jerry@lightstar:~$ exim -v -odf jerryvb@???
this is a test message.
.
LOG: MAIN
<= jerry@??? U=jerry P=local S=298


The test message is never delivered to jerryvb@???, which is a
real mailbox that I have. So, it looks like I can send mail to myself at
ispwest.com, but I cannot send mail "through" ispwest.com to a remote
mailbox. Why is that? All I want, is to use Exim as a client, so that I
can send mail using Mutt. Thank you for any help.
