Yandex Connect, where to migrate?

Question

Domain Name System

On November 27, 2018, I connected the domain to Yandex Connect, the confirmation by the html file was instant, but Yandex Connect allegedly does not see the MX records until now. 6 days have passed! They don't answer letters.
Yandex Connect let me down, because I recommended mail to my client for a domain on Yandex, and now I'm ashamed. Please suggest suitable options. Really only mail.ru remained from free an adequate variant?
And why did pdd.yandex.ru have to be closed...

Answer 1

Our mx check does not pass either, but the letters fly perfectly, these are most likely glitches of the new version, after switching from pdd, since some have a similar problem. Well, those support for Yandex, as always, freezes ...
