# Feature: #92531 - Improved Email Validation {#feature-92531}

See [forge#92531](https://forge.typo3.org/issues/92531)

## Description {#description}

The method `\TYPO3\CMS\Core\Utility\GeneralUtility::validEmail()` is used to
validate a given email address through the core and TYPO3 extensions.

The validation can now be configured by providing the used validators in
the `LocalConfiguration.php` or `AdditionalConfiguration.php`:

```php
$GLOBALS['TYPO3_CONF_VARS']['MAIL']['validators'] = [
  \Egulias\EmailValidator\Validation\RFCValidation::class,
  \Egulias\EmailValidator\Validation\DNSCheckValidation::class
];
```

By default, the validator `\Egulias\EmailValidator\Validation\RFCValidation`
is used. The following validators are available by default:

-   `\Egulias\EmailValidator\Validation\DNSCheckValidation`
-   `\Egulias\EmailValidator\Validation\SpoofCheckValidation`
-   `\Egulias\EmailValidator\Validation\NoRFCWarningsValidation`

Additionally it is possible to provide an own implementation by implementing the
interface `\Egulias\EmailValidator\Validation\EmailValidation`.

If multiple validators are provided, each validator must return `TRUE`.

## Impact {#impact}

Using additional validators can help to identify if a provided email address is
valid or not.
