使用PHP发送邮件出现这个错误:The following From address failed:[e-mail]

Question

使用了TP框架!以下是源码:

<?php
namespace Api\Controller;

use Think\Controller;

class EmailController extends Controller
{
  public function test(){
      $msg = pmail('[e-mail]','午夜DJ','封装测试','hello world');
      echo $msg;
  }
?>

==========================================================================

<?php
return array(
    //'配置项'=>'配置值'
    'TMPL_PARSE_STRING' => array(
        '__ADMIN__' => '/Public/Admin',
        '__COMMON__' => '/Public/Common',
        '__VENDORS__' => '/Public/Venders',
        '__HOME__' => '/Public/Home',
        '__USER__' => '/Public/User',

        '__UP_GOODS__'=>'/Public/Uploads/Goods',
        '__UP_USER__'=>'/Public/Uploads/User'

    ),

    'PMAIL' => array(
        'Host' => 'stmp.163.com',
        'Username' => 'xxxxxx',
        'Password' => 'xxxxxx',
        'From' => '[e-mail]',
        'FromName' => 'xxxx',
    ),

);

===========================================================================

<?php
function pmail($tomail = '',$toname = '',$title = '',$content = ''){
    require_once VENDOR_PATH.'PHPMailer/class.phpmailer.php';
    // 实例化
    $pm = new \PHPMailer();
    foreach (C('PMAIL') as $k => $v){
        $pm->$k = $v;
    }
// 服务器相关信息
//    $pm->Host = 'smtp.163.com'; // SMTP服务器
    $pm->IsSMTP(); // 设置使用SMTP服务器发送邮件
    $pm->SMTPAuth = true; // 需要SMTP身份认证
//    $pm->Username = 'woainigui8888'; // 登录SMTP服务器的用户名
//    $pm->Password = '7618387asd'; // 登录SMTP服务器的密码
//
//// 发件人信息
//    $pm->From = '[e-mail]';
//    $pm->FromName = '电音之王';

// 收件人信息
    $pm->AddAddress($tomail,$toname); // 添加一个收件人

// 邮件内容
    $pm->CharSet = 'utf-8'; // 内容编码
    $pm->Subject = $title; // 邮件标题
    $pm->MsgHTML($content); // 邮件内容
// $this->AddAttachment($path); // 附件

// 发送邮件
    if($pm->Send()){
        return true;
    }else {
        return $pm->ErrorInfo;
    }
}
