How to properly use sending emails on Laravel?

Question

Laravel

Good afternoon!
I decided to use Laravel tools to send emails to e-mail using SMTP. But I've run into a problem that I can't solve.
Email sending code:

$subject = ($act == 0) ? trans('backend/users.activation_off_subject') : trans('backend/users.activation_on_subject');
$message = ($act == 0) ? trans('backend/users.activation_off_message') : trans('backend/users.activation_on_message');
$from = Settings::first()->email;
$mail = $user->email;

Mail::raw($message, function($mess) use ($from, $mail, $subject) {
    $mess->from($from, 'Test');
    $mess->to($mail)->subject($subject);
});

But this error pops up:

Whoops, looks like something went wrong.
Swift_TransportException in AbstractSmtpTransport.php line 383:
Expected response code 220 but got code 503, with message 503 Bad sequence of commands

The SMTP settings must be correct, as they told me in support.
Tell me, please, what is the problem and how to solve it?

Problem solved.
You need to comment out the line in config/mail.php'encryption' => env('MAIL_ENCRYPTION', 'tls'),
