Hi everybody, I’m new to the Zend / Laminas world so I don’t kow if this is the right question to do.

I’m trying to make some testing with laminas sending e-mails via SMTP, but can’t make it work.

```php
use Laminas\Mail\Message;
use Laminas\Mail\Transport\Smtp as SmtpTransport;
use Laminas\Mail\Transport\SmtpOptions;

$transport = new SmtpTransport();
$options = new SmtpOptions(array(
    'name' => 'my.smtp.com',
    'host' => 'imap.gmail.com',
    'port' => 995,
    'connection_class' => 'login',
    'connection_config' => array(
        'ssl' => 'SSL',
        'username' => 'my_mail@gmail.com',
        'password' => 'my_password'
    )
));
$transport->setOptions($options);

$message = new Message();
$transport->send($message);

```

It was just like in the examples, but when i run it I get this error:

```auto
PHP Fatal error: Uncaught Laminas\ServiceManager\Exception\ServiceNotFoundException:Unable to resolve service "Laminas\Mail\Protocol\Smtp\Auth\Login" to a factory; are you certain you provided it during configuration? in /ServiceManager.php:588

```

But I can’t find any reference anywhere that states that I have to define a factory for Smtp/Login.  
And it is a Laminas internal class, I dont know what to do. Please, help!

Hi!  
I’d recommend you to confirm that you have a “Laminas\Mail” item in your modules.config.php. Probably the module declares the factory…

Thanks for your help, do you mean in Laminas\Mail module? Or in my laminas MVC app config?

I just discovered the problem is related to the Smtp Auth since sending my message with FileTransport or Sendmail does work!

In your Laminas MVC config/modules.config.php, like here: [passwordless-auth-example/modules.config.php at master · renanliberato/passwordless-auth-example · GitHub](https://github.com/renanliberato/passwordless-auth-example/blob/master/config/modules.config.php#L15)
