How to connect swiftmailer (Yii2) and Yandex mail for domain?

Question

Yii

In config:

'mailer' => [
            'class' => 'yii\swiftmailer\Mailer',
            'viewPath' => '@common/mail',
            'useFileTransport' => false,
            'transport' => [
                'class' => 'Swift_SmtpTransport',
                'host' => 'smtp.yandex.ru',
                'username' => '[email protected]',
                'password' => 'тут пароль',
                'port' => '465',
                'encryption' => 'SSL',
            ],
        ],

In the model:

public function sendEmail()
    {

        $mailbody = '<h3>Отзыв с сайта</h3>
                            <p><b>Имя:</b> '.$this->name.'</p>
                            <p><b>e-mail:</b> '.$this->email.'</p>
                            <p><b>Тема:</b> '.$this->subject.'</p>
                            <p><b>Текст:</b></p>
                            <p>'.$this->body.'</p>
                            <a href="mailTo:'.$this->email.'">Ответить</a>
                            ';
        return Yii::$app->mailer->compose()
        ->setFrom('[email protected]')
        ->setTo('[email protected]')
        ->setSubject($this->subject)
        ->setTextBody($mailbody)
        ->send();
    }

At the same time I get:
Connection could not be established with host smtp.yandex.ru [Unable to find the socket transport "SSL" - did you forget to enable it when you configured PHP? #-1217465860] I
contacted the hosters, they say that I need to dig in the script because everything works for them (SSL).
Already the brain bursts with this supposedly very convenient swiftmailer. Help with advice or advise an analogue to send yourself an email from the feedback form.

Answer 1

'host' => 'ssl://smtp.yandex.com',
and the rest is all right, just 'encryption' => 'SSL',
need to remove

Answer 2

Carried. I'll add it so I don't forget.
I tried to send via mailbox registered on pdd.yandex.ru and got error
It turned out that it was necessary to enter the mailbox through the web interface and fill in the fields.

Answer 3

SSL > TLS

Answer 4

AND 465 > 587

Answer 5

It works for me like this:

'mailer' => [
            'useFileTransport' => false,
            'transport' => [
                'class' => 'Swift_SmtpTransport',
                'host' => 'smtp.yandex.ru',
                'username' => 'мыло для домена',
                'password' => 'пароль',
                'port' => '25',
                'encryption' => 'tls',
            ],
        ],
