The field under validation must be formatted as an e-mail address. Under the hood the rule makes use of the [`egulias/email-validator`](https://github.com/egulias/EmailValidator) package for validating the email address.

- `strict`: `NoRFCWarningsValidation`
- `dns`: `DNSCheckValidation`
