如何在专用服务器上使用IIS6 SMTP从ASP.NET发送邮件？

我正在尝试配置一个运行ASP.NET的专用服务器，以通过本地IIS SMTP服务器发送邮件，但邮件被卡在队列文件夹中，无法传递

我在.aspx页面中使用此代码来测试：

<%@ Page Language="C#" AutoEventWireup="true" %>

<% new System.Net.Mail.SmtpClient("localhost").Send("info@thedomain.com", 
    "jcarrascal@gmail.com", "testing...", "Hello, world.com"); %>    

最后，我运行SMTPDiag.exe工具，如下所示：

C:\>smtpdiag.exe info@thedomain.com jcarrascal@gmail.com

我正在使用ASP.NET2.0、Windows2003Server和它附带的IIS

你能告诉我还需要做些什么来解决这个问题吗

谢谢

这是一个专用服务器，这就是我手动安装SMTP的原因

编辑：我使用exchange，所以它有点 不同，但它被称为智能主机 在交换中，但在普通SMTP服务中 我想这叫什么 其他的我记不清确切的日期了 设置名称

感谢您为我指出智能主机领域。邮件现在正在投递

在默认SMTP虚拟服务器属性的“传递”选项卡中，单击“高级”，并用提供商提供的地址填充“智能主机”字段。在我（GoDaddy）的例子中，它是k2smtpout.secureserver.net

更多信息：

我发现最好的办法通常取决于电子邮件的数量，就是通过ISP的SMTP服务器转发邮件。减少头痛。看起来这是您遇到问题的地方，从SMTP到外部服务器，而不是asp.net到SMTP

只需将SMTP服务器设置为发送到ISP，或者您可以配置asp.net以发送到ISP

编辑：我使用exchange，所以它有点不同，但它在exchange中被称为智能主机，但在普通SMTP服务配置中，我认为它被称为其他东西

我记不清确切的设置名称。

从外观上看，您的防火墙不允许SMTP（TCP端口25）从您的网络中退出。

两个非常明显的问题（以防它们没有被涵盖） 1.windows防火墙是否已禁用？ 2.您是否有阻止邮件发送的个人/公司防火墙
