If I remember correctly (and I've now been away from Exim for over a
year, so maybe I don't :-), the test suite contains a fake "nameserver"
that can be made to delay and otherwise give non-normal responses. Grep
the Exim code for stuff about testing and take a look at the scripts and
other documentation in the test suite.
