I came here to grump about the fact that if Tutanota cared about privacy they would upgrade from using STARTTLS to using DANE for SMTP.
But lo and behold tutanota.de is using DANE for SMTP. I know the last time I checked they didn't have it, and I think that was a few months ago or maybe a year.

Good job Tutanota!
