Not true. Exim is trying to look up an MX record in the DNS.

What do you get from an nslookup that explicitly looks for MX records?

See? Here Exim is trying to look up an MX record, and the resolver is
giving TRY_AGAIN as the result.
Why this should happen is mysterious. Exim just calls the resolver in
what I believe is a pretty standard way. If you run with -d11 instead of
-d9 it will call the resolver with debugging turned on, so you can see
the DNS queries is uses. This may give us a clue as to what is going on.
My version of Exim can resolve pointone.com just fine.
