Why don't they advertise this?
Little "dig"ging showed who your provider is, and Google gives me no results on this feature. Also read related docs too, nothing. Wonder why.

No idea why they don't advertise this feature. They wrote that they only tell about it to people that are actually having a problem about it. I guess it might be easier for them or for other email-ops to handle abuse/spam issues when this header is available?
