When moving a domain, what should I do with Yandex.Mail?

Question

Yandex

When you change a hoster for a domain, A-records change, but what to do with Yandex corporate mail, do I need to change something?

Answer 1

If the domain name has not changed, then just make sure that the same mx records remain (well, TXT, which Yandex advised adding) and that's it.
