I think detecting dane smtp is a good thing as it gives another metric to test on. I don't think it says anything directly about ham/spam, but may be useful in macros. DKIM/SPF was widely adopted by spammers fairly early after portions of the tech community talked about whitelisting authenticated mail. You might remember one early point when a significant portion of the early-adopters were spammers and legit sites hadn't caught up yet. The same will happen with dane as usage expands -- some clever spam-support tech will develop a tool to easily mass-configure dane for throwaway domains. This isn't necessarily a bad thing in itself, but it means that the mere presence of dane can't determine ham/spam. -- Noel Jones
