[exim] "no IP address found for host" weird error log.

First off:
Exim 4.50 (Debian package)
Linux (Debian)
Using a hand written exim4.conf file instead of Debian's.

Here is a segment of my mainlog from yesterday. Is there some reason why the log is showing the KFSA problem with so many different IP addresses? I'm in the process of trying to get their tech people on the phone so they can fix their server's name.

I do see other "no IP address found for host" errors, but they all seem to function correctly. They are only one line and list only the server name that is trying to send.
