-fakens, are:
-
test.again.dns This always provokes a TRY_AGAIN response, for testing the
handling of temporary DNS error. If the full domain name
starts with digits, a delay of that many seconds occurs.
test.fail.dns This always provokes a NO_RECOVERY response, for testing

The use of gethostbyname() and its IPv6 friends is also subverted when Exim is
running in the test harness. The test code handles a few special names
directly; for all the others it uses DNS lookups, which are then handled as
