How to set up yandex mail for domains on Mac OS Big Sur?

Question

macOS

I would never have thought that I would ask such a question.

From Big Sur sawed fine mail settings. Now neither port nor SSL authorization is available for configuration. Yandex mail from the domain is not configured. The generated password for the application does not help. Authorization fails.

Zoomers rule, damn it. They break what was not broken and cut off all possible ways for at least some fixing.
Maybe there is some tweaker for mail settings?

Answer 1

Found some tweaks.

Answer 2

MDM profile or System Preferences > Internet Accounts > Add Other Account > Mail Account
