DANE makes Tutanota emails extra secure

Tutanota is one of the few email services that already support DANE. The DANE protocol makes email communication much more secure and should be implemented by all mail providers. Tutanota supports DANE on the mail server, which adds another level of security to the communication with other email services that also support DANE.
