Have a form for the user to fill.

Name, phone, birth date, email.

is there a way of detecting if the email is a valid real address? (like [somethin@domain.com](mailto:somethin@domain.com)?) avoiding the user to fill [somethin.domain.com](http://somethin.domain.com)…

the same for name (avoiding numbers and phone number avoiding letters?

Thanks
