I had this one lingering in my development installation.
Make sure you configure your composer.json so that the App\\
namespace resolves with PSR-4 to the app\
directory:
"autoload": {
"psr-4": {
"App\\": "app/"
}
},
Then create app/Extend/MailBin.php
:
<?php
namespace App\Extend;
use App\Mail\ArrayDriver;
use Flarum\Extend\ExtenderInterface;
use Flarum\Extension\Extension;
use Illuminate\Contracts\Container\Container;
class MailBin implements ExtenderInterface
{
public function extend(Container $container, Extension $extension = null)
{
$container->extend('mail.supported_drivers', function () {
return [
'array' => ArrayDriver::class
];
});
}
}
This removes all registered mail drivers and registers the driver that doesn't do a thing.
In extend.php:
return [
new App\Extend\MailBin,
];
