configs can be placed into it. A suitable file location is .../exim/test/trusted_configs

DISABLE_D_OPTION must not be used. If ALT_CONFIG_PREFIX is used, it
must contain the directory of the test-suite. WHITELIST_D_MACROS should contain:
Finally, "exim" can be preceded by "sudo", to run Exim as root. If more than
one of these prefixes is present, they must be in the above order.

Here is a simple example of server use in a test script:
dynamic zone files for the name of the current host and its IP address(es). The
idea is that there should not be any need to rely on an external DNS.
-The domain names that are handled directly by Exim, without being passed to
-fakens, are:
+The fakens program handles some names programmatically rather than using the
+fake zone files. These are:
+
+ manyhome.test.ex This name is used for testing hosts with ridiculously large
+ numbers of IP addresses; 2048 IP addresses are generated
+ and returned. Doing it this way saves having to make the
+ interface to fakens handle more records that can fit in the
+ data block. The addresses that are generated are in the
+ 10.250.0.0/16 network.
test.again.dns This always provokes a TRY_AGAIN response, for testing the
handling of temporary DNS error. If the full domain name
test.fail.dns This always provokes a NO_RECOVERY response, for testing
DNS server failures.
-This special handling could now be done in the fakens program, but while the
-old test suite is still being used it has to be done in Exim itself, so for the
-moment it remains there.
-
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
just described. Thus, the use of /etc/hosts is completely bypassed. The names
that are specially handled are:
- manyhome.test.ex This name is used for testing hosts with ridiculously large
- numbers of IP addresses; 2048 IP addresses are generated
- and returned. Doing it this way saves having to make the
- interface to fakens handle more records that can fit in the
- data block. The addresses that are generated are in the
- 10.250.0.0/16 network.
-
localhost Always returns 127.0.0.1 or ::1, for IPv4 and IPv6 lookups,
respectively.
