Php 从Laravel应用程序发送的电子邮件使用noreply而不是应用程序名称

我正在使用此功能从我的laravel应用程序发送电子邮件，但电子邮件将以

noreply

作为发件人的名称，而不是mail.php文件中设置的

APP name

。可以采取什么措施使电子邮件以应用程序名称而不是

noreply

名称发送

$sender\u name=“我的应用程序名称”； 配置：

{"name":"smtp","host":"mail.mydomain.com","port":"587","enc":"tls","username":"noreply@mydomain.com","password":"mypassword","driver":"smtp"}

mail.php:

 'from' => [
        'address' => env('MAIL_FROM_ADDRESS', 'noreply@mydomain.com'),
        'name' => env('MAIL_FROM_NAME', 'App Name'),
    ],

helper.php

：

function send_smtp_mail($config, $receiver_email, $receiver_name, $sender_email, $sender_name, $subject, $message)
{
    $f = fsockopen($config->host, $config->port);
    if ($f !== false) {
        $res = fread($f, 1024);
        if (strlen($res) > 0 && strpos($res, '220') === 0) {
            $mail_val = [
                'send_to_name' => $receiver_name,
                'send_to' => $receiver_email,
                'email_from' => $sender_email,
                'email_from_name' => $sender_name,
                'subject' => $subject,
            ];
            Config::set('mail.driver', $config->driver);
            Config::set('mail.from', $config->username);
            Config::set('mail.name', $sender_name);
            Config::set('mail.host', $config->host);
            Config::set('mail.port', $config->port);
            Config::set('mail.username', $config->username);
            Config::set('mail.password', $config->password);
            Config::set('mail.encryption', $config->enc);
            $xx = Mail::send('partials.email', ['body' => $message], function ($send) use ($mail_val) {
                $send->from($mail_val['email_from'], $mail_val['email_from_name']);
                $send->replyto($mail_val['email_from'], $mail_val['email_from_name']);
                $send->to($mail_val['send_to'], $mail_val['send_to_name'])->subject($mail_val['subject']);
            });
        }
    }
}

是否检查了.env文件中的值？
