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,但邮件卡在 Queue 文件夹中并且无法传递。
我在 .aspx 页面中使用此代码进行测试:
<%@ Page Language="C#" AutoEventWireup="true" %>
<% new System.Net.Mail.SmtpClient("localhost").Send("info@thedomain.com",
"jcarrascal@gmail.com", "testing...", "Hello, world.com"); %>
然后,我将以下内容添加到 Web.config 文件中:
<system.net>
<mailSettings>
<smtp>
<network host="localhost"/>
</smtp>
</mailSettings>
</system.net>
在 IIS 管理器中,我在“默认 SMTP 虚拟服务器”的属性中更改了以下内容。
General: [X] Enable Logging
Access / Authentication: [X] Windows Integrated Authentication
Access / Relay Restrictions: (o) Only the list below, Granted 127.0.0.1
Delivery / Advanced: Fully qualified domain name = thedomain.com
最后,我像这样运行 SMTPDiag.exe 工具:
C:\>smtpdiag.exe info@thedomain.com jcarrascal@gmail.com

Computer name is THEDOMAIN.

我正在使用 ASP.NET 2.0、Windows 2003 Server 和它附带的 IIS。
你能告诉我还有什么可以改变来解决这个问题吗?
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:我使用交换,所以它有点不同,但它被称为交换智能主机,但在普通的 SMTP 服务配置中,我认为它叫做别的东西。不记得确切的设置名称。
感谢您将我指向智能主机领域。邮件现在正在送达。
在“默认 SMTP 虚拟服务器”属性的“传递”选项卡中,单击“高级”并在“智能主机”字段中填写您的提供商为您提供的地址。就我而言(GoDaddy),它是 k2smtpout.secureserver.net。
