asp.net 密码恢复不起作用

Question

我正在尝试了解 ASP.NET 会员资格的密码恢复技术。

这是我的 web.config 文件：

<?xml version="1.0"?>
<!-- 
    Note: As an alternative to hand editing this file you can use the 
    web admin tool to configure settings for your application. Use
    the Website->Asp.Net Configuration option in Visual Studio.
    A full list of settings and comments can be found in 
    machine.config.comments usually located in 
    \Windows\Microsoft.Net\Framework\v2.x\Config 
-->
<configuration>
    <appSettings/>  
  <connectionStrings>
    <remove name="LocalSqlServer"/>
    <add name="LocalSqlServer" connectionString="Data Source=localhost;Initial Catalog=aspnet_membership_test;Integrated Security=True" providerName="System.Data.SqlClient"/>
  </connectionStrings>
    <system.web>
        <!-- 
            Set compilation debug="true" to insert debugging 
            symbols into the compiled page. Because this 
            affects performance, set this value to true only 
            during development.
        -->
        <compilation debug="true"/>
        <!--
            The <authentication> section enables configuration

        -->
    <authentication mode="Forms">
      <forms loginUrl="~/Login.aspx">         
      </forms>      
    </authentication>
    <authorization>
      <allow users="*"/>      
    </authorization>
        <!--

            of what to do if/when an unhandled error occurs 
            during the execution of a request. Specifically, 
            it enables developers to configure html error pages 
            to be displayed in place of a error stack trace.

        <customErrors mode="RemoteOnly" defaultRedirect="GenericErrorPage.htm">
            <error statusCode="403" redirect="NoAccess.htm" />
            <error statusCode="404" redirect="FileNotFound.htm" />
        </customErrors>
        -->
    </system.web>

  <location path="SecuredPage.aspx">
    <system.web>
      <authorization>
        <deny users="?"/>
      </authorization>
    </system.web>
  </location>

  <system.net>
    <mailSettings>
      <smtp deliveryMethod="Network" from="[email protected]">
        <network host="mail.yahoo.com"
        port="25" defaultCredentials="true"/>
      </smtp>
    </mailSettings>
  </system.net>




</configuration>

但我从 IIS 收到此错误：

可能是什么问题？

Answer 1

您似乎正在尝试使用雅虎的服务器发送电子邮件。如果您还没有注册他们的高级邮件，您将无法这样做。

如果您确实有该服务，请查看此参考以正确设置它：

Answer 2

我认为您使用了错误的 Yahoo SMTP 服务器端口。根据此链接，您应该使用端口 465。
