请教发送邮件的问题！！

[vampireal]

我做了个发送邮件的小程序，通过SMTP来发送，但现在的很多邮箱，比如，sina，sohu，163的SMTP都需要到服务器上验证，否则无法发送，请问那个验证的怎么做啊？？望各位大虾指教！

[microyzy]

我也没做过，gz一下

May you succeed!

我网站那里有个登陆的发送、接收例子，你可以参考。

nonocast(如果没有如果)
您写的只是[e-mail]的，我希望的是只要再输入一遍用户名和密码就通过SMTP的验证，现在的大部分邮箱都需要SMTP的验证，如果不能通过的话，邮件也就发不出去了，那这个程序就没什么价值了，还请您再看看
zhaowenlong(梦难求)
您的这个函数好象并不包含SMTP验证的部分，是否误解了我的意思？



再次感谢各位的热情帮助，希望继续关注，谢谢了
