请教如下的代码为什么不可以发送电子邮件

Question

我想写个可以发送电子邮件的程序，我在程序写了如下的代码，想知道是不是可以发送电子邮件，可是却不行，请问为什么
CSocket sock;
sock.Create();
sock.Connect("smtp.sina.com.cn",25);
char buf[512];
wsprintf(buf,"HELO %s\r\n","com");
sock.Send(buf,strlen(buf));
wsprintf(buf,"AUTH LOGIN\r\n");
sock.Send(buf,strlen(buf));
//开始验证身份，发送经过base64编码的用户名和密码
wsprintf(buf,"%s\r\n","YXNkZmc2OTE3");
sock.Send(buf,strlen(buf));
wsprintf(buf,"%s\r\n","asweertY3MzI");
sock.Send(buf,strlen(buf));
wsprintf(buf,"MAIL From:<%s>\r\n","[email protected]");
sock.Send(buf,strlen(buf));
wsprintf(buf,"RCPT TO:<%s>\r\n","[email protected]");
sock.Send(buf,strlen(buf));
wsprintf(buf,"DATA\r\n");
sock.Send(buf,strlen(buf));
wsprintf(buf,"SUBJECT:%s\r\n","[email protected]");
sock.Send(buf,strlen(buf));
wsprintf(buf,"%s\r\n","[email protected]");
sock.Send(buf,strlen(buf));
wsprintf(buf,".\r\n");
sock.Send(buf,strlen(buf));
为什么不可以发送 电子邮件呢？请大家帮助我，我的qq是79110201，我的email是
[email protected]

你检查过命令返回内容吗？还有这能编译通过？
char buf[512];
wsprintf(buf,"HELO %s\r\n","com");buf是非UNICDE版的字符串，wsprintf是用来格式化UNICODE字符串的
