yii framework email sending steps:

1. Set up the configuration file, main.php

'mailer' => [
        'class' => 'yii\swiftmailer\Mailer',
        'viewPath' => '@common/mail',
        'useFileTransport' => false,//这句一定有，false发送邮件，true只是生成邮件在runtime文件夹下，不发邮件
        'transport' => [
            'class' => 'Swift_SmtpTransport',
            'host' => 'smtp.exmail.qq.com',  //每种邮箱的host配置不一样
            'username' => '*******@jwsem.com',
            'password' => '********',
            'port' => '465',//企业邮箱，163邮箱服务器端口为： 25
            'encryption' => 'ssl',
        ],
        'messageConfig' => [
            'charset' => 'UTF-8',
            'from' => ['*******@jwsem.com' => '系统']
        ],
    ],

2. Use in the controller

                $mail =\Yii::$app->mailer;
                $mail->useFileTransport = false;//不加此句时，如果收不到邮箱，就是在其他环境设置时是true，所以此处可以加上此句，避免收不到邮箱
                $mail->compose()
                    ->setFrom([*******@jwsem.com'=>'系统'])
                    ->setTo(['*******@jwsem.com','*******@qq.com'])//此处为数组时可以发给多个人
                    ->setSubject('邮箱标题')
                    ->setTextBody('姓名：小花，'  电话：132****8564.')
                    ->send();

Note: During the development of a certain project, this email of mine I couldn't send it. I looked at the configuration in the configuration file and found that 'useFileTransport' => false was correct. Later I found that the configuration in the test environment was 'useFileTransport' => true. At this time, I also added it in the controller. After setting 'useFileTransport' => false, it can be sent normally, but the final reason is to change the configuration in the test environment to false.
