Why doesn't google mail for domain work?

Question

Domain Name System

Letters from mailboxes like [email protected] do not come to the mail and they come from [email protected] ([email protected]) mailboxes.
How it happened:
There was mail for the domain from Google. I transferred the site to another hosting, and registered the Yandex domain
dns1.yandex.net
dns2.yandex.net
In managing dns, Yandex suggested copying the current dns settings in which there were lines for Google mail to work, I did so. The site has earned on a new hosting, mail has earned. But the next day, the mail stopped working, and all the lines mentioning Google disappeared in the dns settings.
In general, I made the 3rd and last 5 lines from the documentation. Mail worked, but there was a problem described in the first sentence.

What is the reason that letters do not come from some mailboxes?
Maybe other entries in the dns are to blame and they need to be deleted?
