Google account and Gmail mail has the format my [email protected] Is it possible to receive mail in the format [email protected] on this Google account?

Question

Google

Hello. Approximately 7 years ago, a remotely familiar admin connected mail for domains from Gmail to his city site and adjusted the mail of the form my [email protected] to everyone . This mailbox is also my Google account. Those. authorization in Google services just happens also through the mail of the format [email protected], and not [email protected], as is usually the case.
The site still exists and doesn’t seem to be going to close, but there are a number of questions:
1. Can the site admin get access to my correspondence if he wants (2fa has been installed on the Google profile in which I log in through my [email protected] for three years already)
2. Is it possible to somehow get rid of this mail in the format [email protected], so that all letters are redirected to mail in the format [email protected]?
3. If the site closes and the server is down, will I lose access to my mail and my Google account?
4. If there is a need, is it possible to delete this mail bypassing the administration of the site site.ru ?
I apologize if I didn't formulate the question quite normally, I just don't know how else to explain the essence of the question.

If you are talking about https://gsuite.google.com
I hope they will answer in more detail later, but on your own you have done a very unsafe thing by using the mail of the domain of an incomprehensible person. The risks are very high, and the sooner you give it up, the better.
Get mail to [email protected], change the main sites where you are registered to your mail, just make sure that new mail on [email protected] picks up mail using the pop3 protocol from the old one.
In another case, as far as I remember, you can register with Google with your third-party mail, for example [email protected] and use Google services, in this case you just need to create your mail in your current account, and then set up to pick up mail using the pop3 protocol with your old mail
