To archive this I created CustomMailServiceProvider by extending Illuminate\Mail\MailServiceProvider so as to overwrite this method:

protected function registerSwiftTransport(){
    $this->app['swift.transport'] = $this->app->share(function($app)
    {
    return new TransportManager($app);
    });
}

Here is the complete solution

1. I created CustomMailServiceProvider.php in app\Providers

namespace App\Providers;

use Illuminate\Mail\MailServiceProvider;
use App\Customs\CustomTransportManager;

class CustomMailServiceProvider extends MailServiceProvider{

    protected function registerSwiftTransport(){
        $this->app['swift.transport'] = $this->app->share(function($app)
        {
            return new CustomTransportManager($app);
        });
    }
}

2. I created CustomTransportManager.php in app/customs directory - NB: app/customs directory doesn't exist in default laravel 5 directory structure, I created it

namespace App\Customs;

use Illuminate\Mail\TransportManager;
use App\Models\Setting; //my models are located in app\models

class CustomTransportManager extends TransportManager {

    /**
     * Create a new manager instance.
     *
     * @param  \Illuminate\Foundation\Application  $app
     * @return void
     */
    public function __construct($app)
    {
        $this->app = $app;

        if( $settings = Setting::all() ){

            $this->app['config']['mail'] = [
                'driver'        => $settings->mail_driver,
                'host'          => $settings->mail_host,
                'port'          => $settings->mail_port,
                'from'          => [
                'address'   => $settings->mail_from_address,
                'name'      => $settings->mail_from_name
                ],
                'encryption'    => $settings->mail_encryption,
                'username'      => $settings->mail_username,
                'password'      => $settings->mail_password,
                'sendmail'      => $settings->mail_sendmail,
                'pretend'       => $settings->mail_pretend
           ];
       }

    }
}

3. And finally, I replaced 'Illuminate\Mail\MailServiceProvider', in config/app.php with 'App\Providers\CustomMailServiceProvider',
