发件服务NMSMTP怎么设置smtp用户认证信息呢。
 
“我做了个邮件服务器”.是什么意思?
邮件服务器程序是你写的吗?
 
如果是你写的,可以在客户连接发送User命令后,使用Base64编码,使用Auth....
 
准确的说是一个发信机吧,因为我在做一个远程控制软件,想把指定信息发回email,
可现在263和163都要认证,怎么样把我的帐号和密码交互上去。。
 
什么是Base64编码,我不懂,能不能再清楚一点,谢谢
 
你可以看看ICS构件中的SMTPCli!非常的好用!
 
function TTimeEmailForm.DecodeBase64(Source:string):string;

x4:='=';
end;
result:=result+x1+x2+x3+x4;
end;
end;
实用于263,163,SOHU
 
看看smtp 协议的 rfc文档吧。。nmsmtp没有这个认证过程,需要重载一个。。

你根据relpay的信息。作一些判断 334吧。 不过都需要base64编码。。具体。。。

这样,那样, ,,呵呵。
 
随便找的。。
c:ehlo hostname
s:250-smtp.263.net
250-pipelining
250-size 10240000
250-etrn
250-auth login
250-8bitmime
以上是与邮件服务器连接,即nmsmtp1->connect,以下是连接后的验证:
c:auth login
s:334VXNlcm5hbWU6(username:)
c:b(你的用户名转换成base64码)
s:334UGFzc3dvcmQ6(password:)
c:x(你的密码转换成base64码)
nmsmtp有个transaction方法,在onconnect事件中加入验证过程,
nmsmtp1->transaction("auth login"),返回值是334表示通过,可以继续下面的
nmsmtp1->transaction(你的用户名转换成base64码)
nmsmtp1->transaction(你的密码转换成base64码)
如果返回235表示验证成功,你就可以发邮件了

//这是我写的一个演示程序,
//窗体上有一个BUTTON控件,一个LABEL控件,一个NMSMTP控件
//带密码险证的邮件发送程序需要BASE64编码,DecodeBase64和 EncodeBase64
//为解码和编码函数
//在263、163和SOHU上都能发送成功
