邮件程序问题，高手请进！！！
我用delphi的NMSMTP控件做了一个发送邮件的程序，他的各种需要的属性我都在程序中进行了设置
并且程序可以连接到163，263的SMTP服务器，但是我在发送的时候，他报如下的错误：
'553 You are not authorized to send mail as ....,authentication is required'
各位大侠帮帮忙！！

qyluo(小罗子):
TNMSMTP不直接支持"SMTP服务器认证功能"，但可以利用TNMSMTP的Connect事件和继承自TPowerSock的Transaction方法,实现SMTP服务器认证。
使用Transaction方法发出SMTP服务器认证所规定的AUTH LOGIN命令，并输入经过Base64编码后的用户名与密码，可以实现认证！

再说一次嘛！！！
ahpei 2002-11-05
在连接时你需要发送服务器身份认证指令以及用户名与密码.
使用NMSMTP可以做到。

daniel007 2002-11-05
那是你发送的邮件服务器要求发送时也要认证身份造成的，去搜搜以前的帖子，我记得回答过类似的问题
ahpei 2002-11-05
服务器身份认证
qyluo 2002-11-05
不明白，可否说得更清楚一点，我应该怎么做呢！？
ahpei 2002-11-05
服务器安全认证！
