------解决方案--------------------
发送邮件前需要登陆
你有没有发登陆信息给smtp.qq.com服务器?
------解决方案--------------------
1) 检查你的QQ邮箱的POP/SMTP功能有没有打开?
2) 有可能你的程序多次登录,被QQ邮箱当作恶意登录给拒绝了,换其他邮箱发送试试看。
3) 贴出你的代码,要不然别人不知道怎么帮你检查
------解决方案--------------------
很可能是你的qq邮箱的设置错误..看看开通了pop3和smtp服务.

need EHLO and AUTH first !
这个不是说得很清楚了吗?
要先打招呼握手,并请求登陆。
