The openspf.org test suite for RFC 7208, vendored at
hmailserver/source/Server/SMTP/SPF/Conformance/rfc7208-tests.yml and run by the
server's own tests. It is test data rather than code: nothing of it is compiled
into the server and nothing of it is shipped. The file below is a verbatim copy of
rfc7208-tests.LICENSE, which is kept beside the suite, and is here so that this
directory is a complete list of the third-party terms this repository carries.
