Greetings,

DANE and MTA-STS both ensure that email is exchanged encrypted. Together with researchers from Virginia Tech and Max-Planck-Institut für Informatik, we would like to understand the general trends, operational practices, and challenges of MTA-STS protocol from the mail operators' point of view.

It takes around 5-6 minutes and you can stop participating in the study at any time; we would truly appreciate your participation.

We do not collect any personal information and all answers except the first couple of consent questions are optional. If you do not want to answer any questions, please just leave the field blank.

Thank you very much.
