Class Swift_Transport_Esmtp_Auth_CramMd5Authenticator does not exist

Question

I can't seem to send an email with laravel 5.4 on after setting the right configurations in config/mail.php. I'm using smtp driver here is summary of my files.
Here is the config/mail.php

<?php
return [
    'driver'=>env('MAIL_DRIVER', 'smtp'),       
    'host'=>env('MAIL_HOST', 'smtp.gmail.com'),
'port' => env('MAIL_PORT', 587),
'from' => [
    'address' => env('MAIL_FROM_ADDRESS', '[email protected]'),
    'name' => env('MAIL_FROM_NAME', 'National President'),
],
'encryption' => env('MAIL_ENCRYPTION', 'ssl'),
'username' => env('MAIL_USERNAME', 'my-gmail-email'),
'password' => env('MAIL_PASSWORD', 'my-gmail-password'),
'sendmail' => '/usr/sbin/sendmail -bs',
'markdown' => [
    'theme' => 'default',
    'paths' => [
        resource_path('views/vendor/mail'),
    ],
],              

This is the SendActivationEmail class

<?php

use Illuminate\Bus\Queueable;                                      
use Illuminate\Notifications\Notification;                                  
use Illuminate\Contracts\Queue\ShouldQueue;                                
use Illuminate\Notifications\Messages\MailMessage;                                    


class SendActivationEmail extends Notification {
    use Queueable;                                                     
    protected $token;                                                  
    public function __construct($token) {
        $this->token = $token;
    }

    public function via($notifiable){
        return ['mail', 'database'];
    }

    public function toMail($notifiable) {
        return (new MailMessage)->subject('Activation Your Account')->greeting('Hello!')->line('You need to activate your email before you can login.')->action('Activate Email', route('activate_account', ['token' => $this->token]))->line('Thank you for joining our Online Community!');
    }
 }      
?>

This is the top part of the error

(1/1) ReflectionException

Class Swift_Transport_Esmtp_Auth_CramMd5Authenticator does not exist in DependencyContainer.php (line 309)

I will be grateful for any help to resolve this error on dreamhost, thanks.

The best way to resolve this problem is to delete the files in the vendor folder and redo composer install and composer update, that's how I fixed my problem
