email validator says that *@* is valid e-mail address

[erikroznbeker]

• Laravel Version: 5.8.18
• PHP Version: 7.2.10
• Database Driver & Version: pqsql

Description: After update to laravel 5.8 e-mail validation seems broken and things like @ are consider valid e-mail addresses.

Steps To Reproduce:

run this PHP unit test:

/**
     * @test
     */

    public function mailValidation() {
        $rules = [
            'email' => ['email']
        ];
        $args = [
            'email' => '*@*'  // "*@*" is not valid e-mail address
        ];
        $this->assertTrue(Validator::make($args, $rules)->fails());
    }

Laravel makes use of https://github.com/egulias/EmailValidator to do email validation so if you feel that this is a bug please open up an issue on their issue tracker: https://github.com/egulias/EmailValidator/issues

• [5.8] Use a library for email validation #26503
• Email validation allows spaces #28233

This issue keeps coming up, I don't think the change to email validation represents what most developers would want/expect. I'd love to see it reconsidered, or the strict email validation becoming opt-in.

I opened discussion beginning of March: laravel/ideas#1555

Please see the links in the comments above and try to search for your issue before opening up a new one. Thanks!

It looks like this cannot be resolved by opening support tickets in the package used for email validation, It already has options to resolve this so those options would need to be somehow integrated into laravel.

I added a comment in laravel/ideas#1555 listed above about modifications that could be made to the email validation rule to get around this. I don't think this is a bug, just there is a number of cases where an override may be required to achieve the needed level of email validation. The package used by laravel supports that, however that control is not extended through rule options.

Until this can be handled by Laravel, one can extend the validator with a custom rule.

Add the following to the boot method of your AppServiceProvider:

use Illuminate\Support\Facades\Validator;

Validator::extend(
    'email_simple',
    function ($attribute, $value, $parameters, $validator) {
        return filter_var($value, FILTER_VALIDATE_EMAIL);
    }
);

This will allow you to use the email_simple validation rule instead.
