Setting up Yandex Connect / Why did mail stop working?

Question

Domain Name System

Mail "[email protected]" linked to the site and configured via Yandex-connect does not work.
After I changed the hosting and accordingly updated the NS (name-server), the mail stopped working.
All settings were specified through the Yandex connection and a dns record was added.
I don’t rummage at all in these things, how to make the mail work further, there is no time to experiment, you need to wait three days for any changes.
in dns record changed new ip. do I also need to change the mx record? or is that enough?

Answer 1

Well, at least throw off your DNS records from the hoster.
And the Yandex.Connect panel, so as not to poke a finger into the sky.
