How to save corporate mail when changing hosting?

Question

Domain Name System

Good afternoon!
There are the following inputs:
a domain on nic.ru (there is access)
an old site on beget (no access to hosting)
a new site on reg.ru (written to replace the old one)

There is also a corporate mail like [email protected], made using Yandex.
Question: if the old domain is connected to the new site (most likely, by specifying dns zones from nic.ru), will this require any reconfiguration of corporate mail for it to work?
Hosting on beget is planned to be disabled.
I do not have access to the mail itself at the moment, but we are solving this issue.
How best to do so that there are no interruptions in the mail?

Thanks in advance for your replies.

Answer 1

Does mail physically live on Yandex servers?
Does the domain name change?
Then what's the problem anyway?
When changing the host, and even in the absence of a host, mail should work.

Answer 2

You need control over dns records, this is a question for your dns host . Moving a domain to a new IP address (new site hosting) means changing one A/AAA dns record. Mail from Yandex will work without changes. To pick up mail from Yandex, it is enough to change one mx dns record too. Mail from Yandex is not tied to IP/hosting, but to a domain name.

Answer 3

If there is a change of ns-records, then all your mail settings are lost. Mail is actually set up again, that is:
1. on the hosting reg ru, their mx records are deleted, most likely they will be registered automatically and the Yandex mx record is added
2. The SPF record will most likely also be added by default, it will need to be edited
3. prescribe DKIM from Yandex Connect and if you do DMARC mailings

Answer 4

site address is usually a DNS record type A (or CNAME)
mail - MX
If you change only the location of the site (which will be in a different location), then you change the A record.
Just don't touch MX (which you now point to Yandex)

Answer 5

No
Mail lives separately from the hosting, nothing will happen to it
