PHPMailer::validateAddress

(Required) The email address to check

(Optional) A selector for the validation pattern to use :
* auto Pick best pattern automatically;
* pcre8 Use the squiloople.com pattern, requires PCRE > 8.0, PHP >= 5.3.2, 5.2.14;
* pcre Use old PCRE implementation;
* php Use PHP built-in FILTER_VALIDATE_EMAIL;
* html5 Use the pattern given by the HTML5 spec for 'email' type form input elements.
* noregex Don't use a regex: super fast, really dumb. Alternatively you may pass in a callable to inject your own validator, for example: PHPMailer::validateAddress('user@example.com', function($address) { return (strpos($address, '@') !== false); }); You can also set the PHPMailer::$validator static to a callable, allowing built-in methods to use your validator.

Default value: null
