Answer 1

Untill your environment is in dev mode, you will never receive the emails.
You have 3 differents way for read the emails:
the dev bar in bottom, if there is not any redirect after send email, you can open and find it there
in the server, looking for runtime/mail/ folder and there will be the sended emails
deploy enviroment from developer to production

Answer 2

The mailer component should be at the same level as model component.
You can configure it as follows:
'mailer' => [
'class' => 'yii\swiftmailer\Mailer',
'viewPath' => '#app/mailer',
'useFileTransport' => false,
'transport' => [
'class' => 'Swift_SmtpTransport',
'host' => 'smtp.mailtrap.io', // your host, here using fake email server (https://mailtrap.io/). You can use gmail: 'host' => 'smtp.gmail.com'
'username' => 'your host username',
'password' => 'your host password',
'port' => '2525',
'encryption' => 'tls',
],
],
