在本地用phpmailer发送邮件成功为什么收不到
 $mail = $user_mail;
  $randval = randstr(6,all);
  $randval = md5($randval);
              setcookie('mail_code2',$randval,time()+172800,'/');
  $code = $mail.'_'.$randval;
  $code = base64_encode($code);
  setcookie('mail_form_code',$code,time()+172800,'/');
  $url=site_url('forget/reset/mail/'.$mail.'/e/'.$randval);
  $body = $this->load->view('mail/content2', array('url'=>$url), true);
  $body  = eregi_replace([\],'',$body);
  $this->phpmail->issmtp();
  $this->phpmail->host = smtp.qq.com;
  $this->phpmail->smtpauth = true;  
  $this->phpmail->host = smtp.qq.com;
  $this->phpmail->port = 25; 
  $this->phpmail->username = 270687913@qq.com;
  $this->phpmail->password = asdfg314159;
  $this->phpmail->setfrom('270687913@qq.com', 'first last');
  $this->phpmail->addreplyto(270687913@qq.com,first last);
  $this->phpmail->msghtml($body);
  $address = $mail;
  echo $address;
  $this->phpmail->addaddress($address, hello world!);
  //$this->phpmail->send();
  if(!$this->phpmail->send()) {
  echo mailer error:  . $this->phpmail->errorinfo;
} else {
  echo message sent!;
}
exit();
  return true;
------解决方案--------------------
phpmailer有debug模式,你开启debug模式让他报错误你就知道问题出在哪里了.
