Answer 1

sina不提供pop3,smtp服务,
你可以用freemail.yeah.net.

Answer 2

sina不提供pop3,smtp服务?
那为什么用outlook可以发送接受？
它还不是用socket来通信？

Answer 3

谢谢jcq指教，我已成功发送，接分吧。

Answer 4

sina的必须验证，你的用户名和密码没有设置，如果你用[email protected]作为发送邮箱的话，那么你的用户就设为“test”,密码就是你的登陆密码。如果不行的话去http://www.21active.com/DataStorage/TechInfo/List.asp?TechType=1&TitleID=78
看看会有收获的。
