推荐答案

尽管你传递了你的用户名和密码，服务器仍然希望你收到消息首先要验证自己。这意味着，服务器是否希望您使用POP3检索邮件，然后它会让您发送邮件。为此，请使用端口110连接到 pop.rediffmailpro.com 并传递以下消息：

Despite you passing your your username and password, the server wants you to "get messages first to authenticate yourself". What this means, is that the server wants you to retrieve your messages using POP3 and then it will let you send the mail. To do this, connect to pop.rediffmailpro.com with port 110 and pass these messages:

USER <username>
PASS <password>
LIST
QUIT

我不知道为什么服务器想要这个，即使你传递了你的用户名和密码，但这就是它所说的。

I don't know why the server wants this even when you pass your username and password, but that's what it appears to tell.
