System.Net.Mail.SmtpException:发送邮件失败 [英] System.Net.Mail.SmtpException:Failure sending mail

问题描述

当我尝试在Web服务器上找到uplodind之后从我的asp.net网站发送邮件时，服务器会通过一个异常--->"System.Net.Mail.SmtpException:发送邮件失败.---> ; System.Net.WebException:无法连接到远程服务器---> System.Net.Sockets.SocketException:连接尝试失败是因为被连接的一方在一段时间后未正确响应，或者建立的连接失败是因为连接的主机未能响应209.173.141.250:25"
但是，当我通过计算机编译该代码时，它就可以正常工作.
谁能告诉我该怎么做才能解决此问题.

推荐答案

这可能是由于各种原因造成的.您需要一一看待它们.
港口开放吗?防火墙权限到位了吗?
进一步确保已在Web.Config中配置SMTP配置:

It can be because of various reasons. You need to look at them one by one.
Is the port open? Firewall permissions in place?
Further make sure you have configured SMTP configuration in Web.Config:

<system.net>
   <mailSettings>
     <smtp from="[e-mail]">
       <network host="somesmtpserver" port="25" userName="name" password="pass" defaultCredentials="true" />
     </smtp>
   </mailSettings>
</system.net>
