Email domain verification?

Question

Yii

Tell me, please, what is the verification option or a ready-made widget for the entered email in the input (For example, to skip gmail.com, but not skip non-existent ones)?

Answer 1

and non-existent did not miss

mail can be on any domain. What does nonexistent mean? There can be no verification method in principle. The domain itself can give 404 or something else, and the mail can work quietly on it. Another question is why? You can simply restrict the acceptance of email in input to only trusted email domains. For example, before the dog input type text and then select with a list. But why? This is a struggle with users, complicating their lives with a complete lack of benefit for you.
