I've got following problem: http://www.openspf.org/Why?id=hhaller%40tuta.io&ip=188.8.131.52&receiver=smtp.wp.pl
How to solve it?
You have to send mails from your mail address via Tutanota. It is not possible to use other mail services to send from Tutanota addresses.

That is not possible as the smtp mail has not been sent via one of our smtp servers but (184.108.40.206). Where did you login? Is there a possibility, that you logged in on a phishing page? If so, please change your password immediately!
The mail was sent from firstname.lastname@example.org (it's e-mail in Tutanota) via Tutanota webmail...
