Where can I get a mailbox that allows you to generate multiple emails, one for each new account?

Question

Email

Where can I get a mailbox that allows you to have as many names as you like, so that you can log in to it and, if necessary, answer emails from the same address they came to.
For example, gmail allows [email protected] addresses with a plus sign like [email protected], [email protected], [email protected] , then they are easy to block when the need disappears. It can also be interesting to see which resource sells emails to spammers. The problem is that all sorts of mail collectors have learned this plus sign and what to cut between it and the dog, and it also doesn’t fit in some validators.
10minutemail and others don't allow you to reply to and store emails permanently.
What are the alternatives?

Answer 1

Own domain and as many emails as you want. And if you also have your own mail server, then generally like a god.

Answer 2

Mail.ru has an anonymizer feature .
