Laravel mail with g suites and XOAUTH2

Leave a Comment

I have a g suites account and applications associated with my e-mails. I was looking at the Laravel mail functions but I do not see any option to log in to gmail smtp with xoauth auth type.

I was using PHPMailer with codeigniter and I had to use clientId, clientSecret and refreshToken to send emails via smtp.gmail.com

Is there any chance I can authenticate using xoauth with native laravel swiftmailer?

Since Laravel doesn't have available configuration to set AuthMode then we need to tweak it a little bit.

  1. Register a new Mail service provider in config/app.php:

    // ... 'providers' => [     // ...      // Illuminate\Mail\MailServiceProvider::class,     App\MyMailer\MyMailServiceProvider::class,      // ... 
  2. app/MyMailer/MyMailServiceProvider.php should create your own TransportManager class:

```

namespace App\MyMailer;  class MyMailServiceProvider extends \Illuminate\Mail\MailServiceProvider {     public function registerSwiftTransport()     {         $this->app['swift.transport'] = $this->app->share(function ($app) {              return new MyTransportManager($app);         });     } } 

```

  1. In the app/MyMailer/MyTransportManager.php we can provide additional configuration to the SwiftMailer:

```

<?php  namespace App\MyMailer;   class MyTransportManager extends \Illuminate\Mail\TransportManager {     /**      * Create an instance of the SMTP Swift Transport driver.      *      * @return \Swift_SmtpTransport      */     protected function createSmtpDriver()     {         $transport = parent::createSmtpDriver();         $config = $this->app->make('config')->get('mail');           if (isset($config['authmode'])) {             $transport->setAuthMode($config['authmode']);         }          return $transport;     } } 

```

  1. Last thing to do is to provide mail configuration with authmode set to XOAUTH2 and password to your access token:

```

<?php  return array(  /* |-------------------------------------------------------------------------- | Mail Driver |-------------------------------------------------------------------------- | | Laravel supports both SMTP and PHP's "mail" function as drivers for the | sending of e-mail. You may specify which one you're using throughout | your application here.

A default option is provided that is compatible with | the Postmark mail service, which will provide reliable delivery. | */  'host' => 'smtp.gmail.com',  /* |-------------------------------------------------------------------------- | SMTP Host Port |-------------------------------------------------------------------------- | | This is the SMTP port used by your application to delivery e-mails to | users of your application.

Here, you may specify a name and address that is | used globally for all e-mails that are sent by your application. | */  'from' => array('address' => 'user@gmail.com', 'name' => 'user'),  /* |-------------------------------------------------------------------------- | E-Mail Encryption Protocol |-------------------------------------------------------------------------- | | Here you may specify the encryption protocol that should be used when | the application send e-mail messages. A sensible default using the | transport layer security protocol should provide great security. | */  'encryption' => 'tls',  /* |-------------------------------------------------------------------------- | SMTP Server Username |-------------------------------------------------------------------------- | | If your SMTP server requires a username for authentication, you should | set it here.

This will be given to the server on | connection so that the application will be able to send messages. | */  'password' => 'YOUR ACCESS TOKEN',  /* |-------------------------------------------------------------------------- | Sendmail System Path |-------------------------------------------------------------------------- | | When using the "sendmail" driver to send e-mails, we will need to know | the path to where Sendmail lives on this server. A default path has | been provided here, which will work well on most of your systems. | */  'sendmail' => '/usr/sbin/sendmail -bs',  /* |-------------------------------------------------------------------------- | Mail "Pretend" |-------------------------------------------------------------------------- | | When this option is enabled, e-mail will not actually be sent over the | web and will instead be written to your application's logs files so | you may inspect the message.
