I'm trying to send emails from Lumen 5.7, so as mentioned by many sources, I ..

1. added illuminate/mail and guzzlehttp/guzzle to my application


2. created "config/mail.php" and "config/services.php" from Laravel Repository
   


3. uncommented $app->withFacades();, registered IlluminateMailMailServiceProvider::class and added $app->configure('services'); and $app->configure('mail'); before return $app; in bootstrap/app.php
   


4. 
   

   added mailgun settings to .env

   
   
   

   MAIL_DRIVER=mailgun

   
   
   

   MAILGUN_DOMAIN=ssss

   
   
   

   MAILGUN_SECRET=xxxxx

   
   



5. tried to send an email Mail::raw('Raw string email', function($msg) { $msg->to(['x@x.com']); $msg->from(['x@x.com']); });

but still get this error message Unable to resolve NULL driver for [IlluminateMailTransportManager].

P.S. This is my first experience with Lumen and I did search to resolve this problem for many hours, but I cannot.

Thanks in advance.

Use mail base config from Laravel (config/mail.php)

    |

    | 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. By default, Laravel is setup for SMTP mail.

    |

    | Supported: "smtp", "sendmail", "mailgun", "mandrill", "ses",

    |            "sparkpost", "log", "array"

];

And don't forget to install dependency

composer require guzzlehttp/guzzle

If the config folder is in the "app" folder, then remove the "config" folder to the "main folder". it works for me.
