How to filter email addresses by domain?

Question

Email

What can you advise about filtering email addresses?
For example, if you need to disable registration by email from services like 10 minutes mail?
If you use a white list, then it is not a fact that all normal domains will be in it. A blacklist is also not an option, since such services change the domain every month. Don't follow everyone.

Answer 1

If e-mail is actually used in working with the user, then he himself will be interested in indicating the real address. Well, if only spam then pours in there, then what's the point of indicating the real address?

Answer 2

Use regular expressions for the presence of parts of '@gmail.ru' or other mailers

Answer 3

Don't make life difficult for users.

Answer 4

If you need real user uniqueness, link to a phone number with SMS confirmation
