Change Laravel mail configuration during runtime

Question

I need to change Laravel Mail Configuration during the runtime. This is because the configuration needs to be changed several times during runtime, not just once on app initialization.

foreach ($emails as $email) {
    Config::set('mail.mailers.smtp.username', $email->email);
    Config::set('mail.mailers.smtp.password', $email->password);
    Config::set('mail.from.address', $email->email);

    Mail::to('someone@example.com')->send(new DemoMail('title', 'body'));
}

As you can see, I am trying to set new configurations on each iteration, but the configuration is only set once (on the first iteration); all other emails are sent using the design from the first iteration.

I have found solutions using Service Providers. Similar to this one Dynamic mail configuration with values from database [Laravel] The problem is that the provider sets mail configuration when the app is initialized and can't be changed during runtime. So this doesn't solve my problem.

The second idea I came up with is to define multiple mail drivers (configurations), one for each email, and then use the mailer() function to specify which one I want to use on each iteration. The problem with this solution is that I need to create those drivers dynamically; I can't hardcode them.

I searched the internet for the right solution, but couldn't find one.

Laravel documentation points that you can set configuration in runtime using config helper if you pass an array key value: `config(['your.config' => 'value'])` — Mahdi Rashidi, Apr 07 '23 at 06:58

@MahdiRashidi Unfortunately, it doesn't. I just tried setting it like this config([ 'mail.mailers.smtp.username' => $email->email, 'mail.mailers.smtp.password' => $email->password, 'mail.from.address' => $email->email ]); But it only sets it once — itstare, Apr 07 '23 at 07:18
@SHEN I tried something simillar to this, but wouldn't this approach just set configuration when app is initialized. I need to reset configuration each time loop runs — itstare, Apr 07 '23 at 07:55

I have found a solution by using Symfony Mailer in Laravel.

foreach ($emails as $email) {
            $transport = new EsmtpTransport('mail.host', 465);
            $transport->setUsername($email->email);
            $transport->setPassword($email->password);

            $mailer = new Mailer($transport);

            $mailable = (new SymfonyEmail())->from($email->email)->bcc('test@test.com')->subject($request->subject)->html('email body');

            $mailer->send($mailable);
        }

Option with swift mailer seems interesting, but swift mailer is not supported in Laravel 9 :( – itstare Apr 07 '23 at 09:08
