Exim uses DNS several times. Probably to lookup the sender domain or the
name of the sending host. Some of these test may be vital, so exim
deferres accepting the mail. Which test is vital depends on your setup.
(Seems to be semi vital, if you say it works w/o DNS.)
So - probably exim contacts the server, the server doesn't answer
properly in time (exim itself will not do any recursion, I'd say) and
exim responses 4xx. If the DNS is off, exim immediatly finds the
connection to the DNS refused and continues.
Exim should use the DNS server found in /etc/resolv.conf. What happens
when your're using DNS test tools querying the above mentioned address?
dig -x 1.1.1.1 @192.168.0.1
dig domain.example @192.168.0.1
