请问谁知道 SMTP 服务器身份验证的消息格式和应答?

请问谁知道 SMTP 服务器身份验证的消息格式和应答? 最好能贴出一段应答内容.

老兄，上面的根本就不行，我正是使用的那种方式， 从 Telnet 测试的结果看，MAIL FROM: 命令就失败了，还用什么 RCPT TO: 命令呢？

身份验证？？？

下面是我用 Telnet 连接 smtp.263.net 的应答过程(ESMTP),发信的请求被拒绝了.我想知道怎么使我的要求不被拒绝.我写了一个 smtp 程序,但是总是收到 505 错误.现在那些服务器都要求身份验证,我是想知道消息格式,不是关于 Socket 方面的内容.

上面例子中不就说明了格式了么？Date,From,To,Subject,X-Mailer

网上有现成的身份验证的收发邮件代码啊。
