Well, that seems clear enough. The destination is unreachable. Exim can
do no more.

At least one of those IP addresses is reachable from here at this time:
$ telnet 209.209.45.154 25
Trying 209.209.45.154...
Connected to 209.209.45.154.
Escape character is '^]'.
220 two.oddpost.com ESMTP
Try that now from your site. If you can't connect, you have a networking
problem. Get your networking experts on to it. If you have none, you'll
have to learn some network debugging fast... Here is my opportunity to
recommend a book written by the person who is publishing my new Exim 4
book (it's at last at the printers, guys).
Practical TCP/IP
Designing, Using, and Troubleshooting TCP/IP Networks on Linux and Windows
by Niall Mansfield
Published by Addison Wesley 2003
ISBN 0 201 75078 3
I haven't finished reading this 850-page tome yet, but so far I have
found it very readable, and a mine of useful information. If you don't know
much about TCP/IP networking, this is where to start learning.
