yii2邮件配置教程，报Expected response code 250 but got code "553"原因

main.php(或main-local.php)或者web.php中的邮件配置如下：

'mailer' => [
    'class' => 'yiiswiftmailerMailer',
    'viewPath' => '@common/mail',
    // send all mails to a file by default. You have to set
    // 'useFileTransport' to false and configure a transport
    // for the mailer to send real emails.
    'useFileTransport' => false,//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.163.com',  //每种邮箱的host配置不一样
        'username' => 'zhong_mail_test',
        'password' => '**********',//163邮箱的授权码
        'port' => '25',
        'encryption' => 'tls',

    ],
    'messageConfig'=>[
        'charset'=>'UTF-8',
        'from'=>['zhong_mail_test@163.com'=>'zhong-mail']
    ],

],

发送邮件的代码如下：

return Yii::$app
    ->mailer
    ->compose(
        ['html' => 'passwordResetToken-html', 'text' => 'passwordResetToken-text'],
        ['user' => $user]
    )
    ->setFrom([Yii::$app->params['supportEmail'] => Yii::$app->name . ' robot'])
    ->setTo($this->email)
    ->setSubject('Password reset for ' . Yii::$app->name)
    ->send();

如就按照上述配置会报：

Expected response code 250 but got code "553", with message "553 Mail from must equal authorized user
"

这是因为有些邮件服务器要求from和username必须一致，163邮箱就是这样。

为避免这个问题，我们可以将发件代码中的setFrom设置去掉，或者在param.php(或param-local.php)中配置supportEmail参数：

'supportEmail' => 'zhong_mail_test@163.com'

这样就能成功发送邮件了。
