摘要：总结一下碰到的问题

1、无法发送附件

附件不能使用url需要使用绝对路径
地址不能用\需要用/

2、from和subject中文乱码，但是内容是正常的

是应为在base64转码的时候发生错误，需要处理
$from_name = $_POST['FromName'];
$mail->FromName = "=?utf-8?B?".base64_encode("$from_name")."?=";

3、调试模式

//Enable SMTP debugging
// 0 = off (for production use)
// 1 = client messages
// 2 = client and server messages
$mail->SMTPDebug = 0;

4、无法用其他的邮箱发送，只能使用gmail

换个稳定的phpmail包
检查host信息
from  setfrom  fromname 这些设置分不清可参考下面的
<?php
/**
 * UserName, Password,  FromAddress,  FromName,  ToAddress,  ToName,  Subject, Body, IsHtml, AltBody,CCAddress
 */

Gmail 发送报错530

打开gmail 中的 安全性较低的访问权限
OK

Gmail腾讯阿里等可以正常，网易邮箱出现乱码

1、查看邮件 在更多里面选择编码 选择utf8发现可以正常显示
2、此时将phpmail中的后续设置的编码设置为utf8同时将包的编码也设置为utf8否则不可以
class.phpmailer.php 中 public $CharSet           = 'UTF-8';  原始为iso-8859-1
具体调用里面 $mail->Charset='UTF-8';
