Test pass.

=== RUN   TestNSLookupMX
--- FAIL: TestNSLookupMX (0.04s)
    lookup_windows_test.go:37: no results

Comment

When I set Google DNS (8.8.8.8) as my DNS server, the test passed.
When I set OpenDNS (208.67.220.220) as my DNS server, the test failed.
Theses tests should not rely on whether CNAME flattening is available on a recursive DNS resolver.
