分享思归,你在吗,救我啊,带星星的哥哥姐姐快来啊(邮件问题 急急急!!!)
我想在Aspnet中发邮件,Smtp服务是缺省本机,老提示错误,
错误提示如下:
Server Error in '/WebSendMail' Application.
--------------------------------------------------------------------------------
The transport failed to connect to the server.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Runtime.InteropServices.COMException: The transport failed to connect to the server.
Source Error:
The source code that generated this unhandled exception can only be shown when compiled in debug mode. To enable this, please follow one of the below steps, then request the URL:
1. Add a "Debug=true" directive at the top of the file that generated the error. Example:
<%@ Page Language="C#" Debug="true" %>
or:
2) Add the following section to the configuration file of your application:
<configuration>
<system.web>
<compilation debug="true"/>
</system.web>
</configuration>
Note that this second technique will cause all files within a given application to be compiled in debug mode. The first technique will cause only that particular file to be compiled in debug mode.
Important: Running applications in debug mode does incur a memory/performance overhead. You should make sure that an application has debugging disabled before deploying into production scenario.

你可以使用SmtpMail.SmtpServer="localhost";
前题是，启动在你的iis中smtp服务器，在访问选项卡中的，中继，把本地ip添加

This error is usually related with SMTP server setting. In some cases, it
is the wrong smtp server name or wrong DNS entry. Here I would suggest:
1. Double check the SMTP server is listen on port 25;
2. The SMTP grant permission to the ASP.NET application to send email. The
default security account for ASP.NET application is <ServerName>\ASPNET.
