+# How to add custom Mail Driver to Laravel
+
+Tested on Laravel 5.8
+
+Within the source code of laravel 5.8 at this time of writing, we have this following
+
+```php
+
+<?php
+
+namespace Illuminate\Support;
+// use...
+
+abstract class Manager
+{
+  //somewhere in the body ...
+
+      /**
+     * Register a custom driver creator Closure.
+     *
+     * @param  string    $driver
+     * @param  \Closure  $callback
+     * @return $this
+     */
+    public function extend($driver, Closure $callback)
+    {
+        $this->customCreators[$driver] = $callback;
+
+        return $this;
+    }
+
+    // the rest of the code...
+}
+
+```
+
+
+## Create a MailDriver class
+
+In this case I am using OutlookMailDriver, and since i am going to the extend method from
+the existing manager, it expects a Closure therefore i make an invocable method that return a function.
+
+```php
+<?php
+declare(strict_types=1);
+
+namespace App\Helpers\Drivers;
+
+
+use App\Helpers\Transports\OutlookTransportManager;
+use Illuminate\Mail\TransportManager;
+
+class OutlookMailDriver
+{
+    public function __invoke(TransportManager $manager)
+    {
+        return function ($app) {
+            $config = $app['config']->get('services.outlook', []);
+            return new OutlookTransportManager($config);
+        };
+    }
+}
+
+```
+
+
+## Create a CustomMailProvider that extend Illuminate\Mail\MailServiceProvider
+
+I am going to override the registerSwiftTransport method yet calling its parent first
+to have it registered its expected Manager then I extend it with my custom Mail Driver.
+
+```php
+
+<?php
+
+namespace App\Providers;
+
+use App\Helpers\Drivers\OutlookMailDriver;
+use Illuminate\Mail\MailServiceProvider;
+use Illuminate\Mail\TransportManager;
+
+class CustomMailProvider extends MailServiceProvider
+{
+    /**
+     * Register the Swift Transport instance.
+     *
+     * @return void
+     */
+    protected function registerSwiftTransport()
+    {
+        parent::registerSwiftTransport();
+
+        $this->app->extend('swift.transport', function (TransportManager $transport) {
+            $transport->extend($driver, $callback($transport));
+            return $transport;
+        });
+    }
+}
+
+```
+
+## Create a class that extends Illuminate\Mail\Transport\Transport
+
+Since `Illuminate\Mail\Transport\Transport` is an abstract class therefore i need to have
+`send` method.
+
+
+```php
+<?php
+declare(strict_types=1);
+
+namespace App\Helpers\Transports;
+
+use Illuminate\Mail\Transport\Transport;
+use Swift_Mime_SimpleMessage;
+
+class OutlookTransportManager extends Transport
+{
+
+    public function __construct($config)
+    {
+        // do your whatever you need here
+    }
+
+    public function send(Swift_Mime_SimpleMessage $message, &$failedRecipients = null)
+    {
+        logger('I am using custom outlook manager');
+        // TODO: Implement send() method.
+        return 0;
+    }
+}
+
+```
+
+## Register the CustomMailProvider in your config/app.php
+
+comment Illuminate\Mail\MailServiceProvider::class within your config, and register your own custom provider there
+
+```php
+return [
+    'providers' => [
+        //...
+        App\Providers\CustomMailProvider::class,
+        //Illuminate\Mail\MailServiceProvider::class, // comment this out
+    ],
+];
+```
+
+## Test
+
+```php
+// somewhere in your route/web.php
+
+Route::get('test', function () {
+    Mail::to('[email protected]')->send(new \App\Mail\Test());
+});
+
+```
+
