Yandex email error: Email sending without SSL/TLS encryption is not allowed

E-mail domain must be registered (served): https://pdd.yandex.ru/

E-mail address in: notification email ( admin/site_settings/category/required ) and DISCOURSE_SMTP_USER_NAME (app.yml) same.

I did register domain and create the email. I can use that email for other purposes. I’ve done that before, so I’m sure domain ownership verification and email creation is working correctly.
