用SmtpMail邮件发送不出去，为什么呢？高分相送，在线等待，问题解决，马上结帐！

[feixiang2003]

代码如下:
....

string body="Thank you!";
MailMessage mail=new MailMessage();
mail.From="[e-mail]";
mail.To="[e-mail]";
mail.Subject="Hello,Everyone!";
mail.Priority=MailPriority.High;
mail.Body=body;
try
{
SmtpMail.Send(mail);
}
catch(Exception es)
{
Response.Write(es.Message);
}
....

运行没有报错，可邮件就是发不出去！

不过在C:\Inetpub\mailroot\Queue目录下又可看到待发的邮件，过了很长时间也是发不出去，待高手们指点！

SOHU的SMTP服务器需要认证吧

//在reference中添加CDO for Windows 2000

using CDO;



public void SendEmail()
{


try
{

conf.Fields[CdoConfiguration.cdoSendUsingMethod].Value=CdoSendUsing.cdoSendUsingPort;

按您方法，出现如下错误：

The message could not be sent to the SMTP server. The transport error code was 0x80040217. The server response was not available

需要邮件接受者那方的邮件服务器的认证哦

打开你的IIS manager，选择SMTP的属性，选择access，选择里面的最后一个按钮 Relay, 选择all except the list below，然后一路ok，一两分钟后，邮件就开始工作了。

------------------------------------
我是用Win2000 OS 我也觉得不是代码的问题，因为我用CDO或其它下载的组件结果都有一样--
邮件都写好了，就是在C:\Inetpub\mailroot\Queue下待发，用你那种方法好像还是不行！

[dawave]

如果发邮件没有报错，但邮件停在队列里，八成就是这个问题，你再仔细查查。试着reboot你的机器。

设置SmtpMail.SmtpServer = 本地smtp地址；要确认这个smtp地址没问题！
然后SmtpMail.Send(mail)；
