main.php(或main-local.php)或者web.php中的邮件配置如下：
'mailer' => [
'class' => 'yii\swiftmailer\Mailer',
'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。
