I want to set the following setting dynamically before I notify the user.

MAIL_DRIVER=
MAIL_HOST=

I am using notification to notify each customer so before I notify I want to set this option dynamically from DB.

Answer 1

these env variables then used in configuration file you can find right config names by checking mail.php in config folder

You can change config values at run time by array to config helper.

See: https://laravel.com/docs/6.x/configuration#accessing-configuration-values

You need to find corresponding variables and set their value like for Laravel - 6

config([
    'mail.driver' => 'smtp',
    'mail.host' => 'smtp.mailgun.org',
    'mail.port' => 587,
    'mail.encryption' => 'tls',
    'mail.username' => 'if-any',
    'mail.password' => 'if-any',
]);

After that your new settings should be used.

One alternative is to create a $mailer and use it, then discard it.

    $swiftMailer = app('mailer')->getSwiftMailer();

    $transport = $swiftMailer->getTransport()
        ->setUsername($username)
        ->setPassword($password)
        ->setHost($host)
        ->setPort($port)
        ->setEncryption($encryption)
        ->setTimeout(30);

    $mailer = app(\Illuminate\Mail\Mailer::class);
    $mailer->setSwiftMailer(new \Swift_Mailer($transport));
    $mailer->alwaysReplyTo($reply_to);
    $mailer->to($user->email)
        ->send(new AdminPasswordReset($data));
