Why is sending mail not working on yii2?

Question

Yii

Good afternoon,
Previously, everything worked and then abruptly stopped checking passwords, but still writes an error 500 when sending mail to firebug. show my
web.php code

'mailer' => [
            'class' => 'yii\swiftmailer\Mailer',
            'transport' => [
                'class' => 'Swift_SmtpTransport',
                'host' => 'smtp.mail.ru',
                'username' => '######@bk.ru',
                'password' => '#####',
                'port' => '587',
                'encryption' => 'tls',
            ],
        ],

controller

Yii::$app->mailer->compose()
            ->setFrom('#####@bk.ru')
            ->setTo('###@gmail.com')
            ->setSubject('####.ru - Новый клиент - '.$name)
            ->setTextBody('Plain text content')
            ->setHtmlBody($body)
            ->send();

I hope someone will tell you, maybe htaccess is necessary? Can with apache2 that happened, I will not understand in any way. Thanks everyone will help.

Answer 1

so you have code 500 - look at the application logs and not the apache.

Answer 2

550 Message was not accepted -- invalid mailbox
Most likely an error in the email address
