Greylisting is not a protocol, according to any definition I know.

There is no way to test "interoperability".

Rubbish. I can assure you that if someone implemented greylisting in such a way that "legitimate" mail stopped being delivered, because they set the greylist timeout too long or because they used a status code that everyone choked on or some other such thing that was underspecified in the RFC, people would say that the implemenation was not interoperating in the mailing transport/delivery system and that implementation experience dictated changes to the specification in order to improve future implementations (assuming that the spec failed to specify the correct parameters). Greylisting is far more obviously a protocol with testable interoperability than is, say, RFC 5234 or 5322.
