$value = Yii::$app->mailer->compose()
            ->setFrom([$this->email => $this->name])
            ->setTo($model->email_1)
            ->setCc($model->email_2)

我刚刚尝试了以下代码,它正在运行.
您的代码中唯一奇怪的东西似乎是在带有Array的setFrom中.

Yii::$app->mailer->compose()
            ->setFrom('addrs1@gmail.COM')
            ->setTo(array('addrs1@gmail.com','addrs2@hotmail.com'))
            ->setCc(array('addrs3@gmail.com'))
            ->setSubject('Sending Email')
            ->setTextBody('This is Plain text content')
            ->setHtmlBody('Please go to  <a href="http://GOOGLE.com/">GOOGLE</a>')
            ->send();

在Swift邮件代码中有以下注释：

* Set the From address of this message.
 *
 * IT is PErmissible for multiple From addresses to be set using an array.
 *
 * If multiple From addresses are used,you SHOULD set the Sender address and
 * according to Rfc 2822,MUST set the sender address.

希望能帮助到你.
