I never found a configuration option in tutanota android app!
I asked to ProtonMail Support about it...

Thank you for your message and support. At this moment we are putting all of our limited resources to building the best private email system. We also are certainly not apposed to joining such a network that promotes Privacy. This includes encrypted connection between Tutanota, as long as the tech is tested and works.

Not now... But I believe this could be possible in next 2 or 3 years... For now, Tutanota and ProtonMail have another important chalanges (as create a basic features as, for example, to create folders.)
About Folders: Folders will be released on February 29t in Tutanota.
I suggested this in a E-mail yesterday to Tutanota Team and I did not read this before!
This is very important to TOR and Privacy... (Remember all of us: We are the resistence!)
The more serious companies enjoy TOR, less power will have the bad reputation of "Deep Web Myth" (reference to Muhammed comment)...
And... I wish to add here the following consideration:
- Maybe Tutanota can be the first company to use DANE feature in a .onion domain!! This would be a kind of revolution! :)
And, ofcourse, get TORProject Team envolved will help a lot!
