问题描述

从我的网站发送邮件时出现以下错误.在本地iis中它可以工作，但是在生产服务器中却出现以下错误.

Sys.WebForms.PageRequestManagerServerErrorException:SMTP服务器需要安全连接，或者客户端未通过身份验证.服务器响应为:5.5.1需要身份验证.

我写的代码是

I am getting following error while sending a mail from my website. In local iis it is working but in production server it is getting following error.

Sys.WebForms.PageRequestManagerServerErrorException: The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.5.1 Authentication Required.

The code i have written is

public void SendMail(string ToEmailAddress, string Body, string Subject)
        {
            SmtpClient smtpClient = new SmtpClient();
            smtpClient.Host = System.Configuration.ConfigurationManager.AppSettings["SmtpClientHost"].ToString();
            smtpClient.Port = Convert.ToInt32(System.Configuration.ConfigurationManager.AppSettings["SmtpClientport"].ToString());
            smtpClient.Credentials = new System.Net.NetworkCredential(System.Configuration.ConfigurationManager.AppSettings["FromEmail"].ToString(), System.Configuration.ConfigurationManager.AppSettings["MailPassword"].ToString());
            smtpClient.EnableSsl = true;
            MailMessage messege = new MailMessage();
            MailAddress mailAddress = new MailAddress(System.Configuration.ConfigurationManager.AppSettings["FromEmail"].ToString(), System.Configuration.ConfigurationManager.AppSettings["Name"].ToString());
            messege.From = mailAddress;
            messege.To.Add(ToEmailAddress);
            messege.Subject = Subject;
            messege.Body = Body;
            messege.IsBodyHtml = true;
            smtpClient.Send(messege);
        }      

在web.config中，我提到了类似
的设置

In web.config i have mention settings like

<appSettings>
       <add key="SmtpClientHost" value="smtp.gmail.com"/>
       <add key="SmtpClientport" value="587"/>
       <add key="FromEmail" value="[e-mail]"/>
       <add key="MailPassword" value="myPassword"/>
       <add key="Name" value="CRACKERSADMIN"/>
   </appSettings>

推荐答案

尝试如下配置，确保已在Web.Config中配置SMTP配置:

Try configuration like following, 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>
