[exim] need help modifying mystery rule

I am running exim4 on Ubuntu 12.0.4 and baruwa 2.0

I am sending test messages from Constant Contact, but they are not
making it through, unless they hit the server after being forwarded from
another domain.

The logs are informational, but there is not a reject line that gives
me a hint what I need to change to let mail through. I have whitelisted
the domains, but things still are not making it through. I have seen
other logs with the same info and the mail goes right through. Any ideas?

2013-02-28 15:33:21 no IP address found for host localhost.localdomain
(during SMTP connection from (ccm169.constantcontact.com) [208.75.123.169])
