Asp.net mvc 3 Elmah不发送电子邮件

我已经在Mvc4应用程序中实现了Elmah。我的web.config如下所示：-

<configuration>
  <configSections>
      <sectionGroup name="elmah">
          <section name="security" requirePermission="false" type="Elmah.SecuritySectionHandler, Elmah" />
          <section name="errorLog" requirePermission="false" type="Elmah.ErrorLogSectionHandler, Elmah" />
          <section name="errorMail" requirePermission="false" type="Elmah.ErrorMailSectionHandler, Elmah" />
          <section name="errorFilter" requirePermission="false" type="Elmah.ErrorFilterSectionHandler, Elmah" />
      </sectionGroup>        
  </configSections>

    <elmah>
        <security allowRemoteAccess="1" />
        <errorLog type="Elmah.XmlFileErrorLog, Elmah" logPath="~/App_Data"/>
        <errorMail from="test@test.in" to="test1@test.in" subject="Elmah Report" async="true" smtpServer="mail.test.in" />            
    </elmah>

  <connectionStrings>
    <add name="DefaultConnection" providerName="System.Data.SqlClient" connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=aspnet-Mvcjquery-20130225111502;Integrated Security=SSPI" />
  </connectionStrings>   

    <system.web>
      <httpHandlers>
          <add verb="POST,GET,HEAD" path="elmah.axd" type="Elmah.ErrorLogPageFactory, Elmah" />         
      </httpHandlers>

      <httpModules>
          <add name="ErrorLog" type="Elmah.ErrorLogModule, Elmah"/>
          <add name="ErrorMail" type="Elmah.ErrorMailModule, Elmah"/>

     </httpModules>        
  </system.web>

  <system.webServer>
      <validation validateIntegratedModeConfiguration="false"/>
      <modules>
          <add name="Elmah.ErrorLog" type="Elmah.ErrorLogModule, Elmah" preCondition="managedHandler" />
          <add name="Elmah.ErrorMail" type="Elmah.ErrorMailModule" preCondition="managedHandler" />
      </modules>

      <handlers>
          <add name="Elmah" path="elmah.axd" verb="POST,GET,HEAD" type="Elmah.ErrorLogPageFactory, Elmah" preCondition="integratedMode" />         
      </handlers>
  </system.webServer>    

</configuration>

我添加了通过elmah发送电子邮件的代码。我可以通过键入url查看错误localhost://elmah.axd.But 我没有收到邮件。请帮助尝试

async=“false”

：

我收到一个异常“SmtpException未被用户代码处理”。发送邮件失败。好的，请查看InnerException。您配置的SMTP服务器可能有问题。是..这是我的SMTP服务器的问题。谢谢您的回答。将async设置为false会改变用户对网站的操作吗？艾玛还会默默地失败吗？

<errorMail 
    from="join@assert.in" 
    to="twinkle@assert.in" 
    subject="Elmah Report" 
    async="false" 
    smtpServer="mail.assert.in" />
