I think a better phrase would be "negotiated unauthenticated TLS". (Or "unauthenticated STARTTLS" since STARTTLS implies negotiated TLS). "Opportunistic" implies that someone is taking advantage of someone else to their detriment, whereas SMTP TLS is by mutual agreement. > Similarly "opportunistic DANE TLS" for case "2" is also reasonable.

The mandatory cases are where the postmaster has overridden normal protocol negotiation, which implies that they should get a weirder name than the normal negotiated cases. Postfix's use of "opportunistic" is a bit weird. Sendmail and Exim do not use the term, though Microsoft Exchange does.
