Dynamic mail configuration with values from database [Laravel]

Question

I have created a service provider in my Laravel Application SettingsServiceProvider. This caches the settings table from the database.

$settings = $cache->remember('settings', 60, function() use ($settings)
    {
        return $settings->pluck('value', 'name')->all();
    });

config()->set('settings', $settings);

settings table:

I am able to echo the value from the table like this:

{{ config('settings.sitename') }}  //returns Awesome Images

This works fine on any blade files or controllers in App\Http\Controllers

Problem:

I am trying to echo the value to App\config\mail.php like this:

'driver' => config('settings.maildriver'),
'host' => config('settings.mailhost'),

But I'm getting this error:

Missing argument 1 for Illuminate\Support\Manager::createDriver()

Update:

I have created a new service provider MailServiceProvider to override the settings in Mail.php like this:

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use Config;

class MailServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap the application services.
     *
     * @return void
     */
    public function boot()
    {
        //
    }

    /**
     * Register the application services.
     *
     * @return void
     */
    public function register()
    {
        Config::set('mail.driver', config('settings.maildriver'));
        Config::set('mail.host', config('settings.mailhost'));
        Config::set('mail.port', config('settings.mailport'));
        Config::set('mail.encryption', config('settings.mailencryption'));
        Config::set('mail.username', config('settings.mailusername'));
        Config::set('mail.password', config('settings.mailpassword'));

    }
}

But still I am getting the same error!!

Is there any way to override default mail configuration (in app/config/mail.php) on-the-fly (e.g. configuration is stored in database) before swiftmailer transport is created?

Struggled for 3 days with this issue finally I figured out a way to solve it.

First I created a table mails and populated it with my values. Then I created a provider MailConfigServiceProvider.php

<?php

namespace App\Providers;

use Config;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\ServiceProvider;

class MailConfigServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap the application services.
     *
     * @return void
     */
    public function boot()
    {
        //
    }

    /**
     * Register the application services.
     *
     * @return void
     */
    public function register()
    {
        if (\Schema::hasTable('mails')) {
            $mail = DB::table('mails')->first();
            if ($mail) //checking if table is not empty
            {
                $config = array(
                    'driver'     => $mail->driver,
                    'host'       => $mail->host,
                    'port'       => $mail->port,
                    'from'       => array('address' => $mail->from_address, 'name' => $mail->from_name),
                    'encryption' => $mail->encryption,
                    'username'   => $mail->username,
                    'password'   => $mail->password,
                    'sendmail'   => '/usr/sbin/sendmail -bs',
                    'pretend'    => false,
                );
                Config::set('mail', $config);
            }
        }
    }
}

And then registered it in the config\app.php

App\Providers\MailConfigServiceProvider::class,
