Thanks for the confirmation.

Note, I still firmly hold that the "o DANE=always" mode is largely
a bad idea.  It is only "useful" when an MX host has its address
records in a signed zone, but its TLSA records are CNAMEd into
an unsigned zone:

	; example.com zone is signed
	example.com. IN MX 0 smtp.example.com.
	smtp.example.com. IN A
	_25._tcp.smtp.example.com. IN CNAME _dane.example.net.

	; example.net zone is not signed
	_dane.example.net. IN TLSA 3 1 1 e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855

Such configurations will be rather rare, and offer minimal incremental
MITM protection.  The code and documentation to support this use-case
and explain it to users are not worth the trouble.
