发送邮件的邮箱设置：
http://www.dede58.com/a/dedesp/1637.html

页面内代码修改：（参考https://blog.csdn.net/zhaoerduo/article/details/16883667，有修改）
1. member/templetes/reg-new3.htm：
<a href="<?php echo $cfg_cmspath; ?>/member/index_do.php?fmdo=email_tiao&email=<?php echo $email;?>" target="_blank">邮箱验证</a>
2. member/index_do.php：
 $url="";里的url需要自己补全，最后的
else
{
    ShowMsg("本页面禁止返回!","index.php");
}
替换为
else if($fmdo=='email_tiao')
