You do not need to edit /vendor files. You can specify (undocumented) options in your config/mail.php file:

'stream' => [
    'ssl' => [
        'allow_self_signed' => true,
        'verify_peer' => false,
        'verify_peer_name' => false,
    ],
],

You can check it yourself in vendor/laravel/framework/src/Illuminate/Mail/TransportManager.php on line ~50:

...
if (isset($config['stream'])) {
    $transport->setStreamOptions($config['stream']);
}
