在ASP.NET中发送邮件 [英] Mail Sending in ASP.NET

问题描述

我正在使用asp.net 3.5版本，并尝试从我的应用程序发送电子邮件.我正在使用以下代码:

Hi,
I am using asp.net 3.5 version and trying to send email from my application. I am using following codes:

MailMessage Mail = new MailMessage();
Mail.From = new System.Net.Mail.MailAddress("username");
Mail.To.Add("recipient mail id");
Mail.Subject = TextBox3.Text;
Mail.Body = TextBox4.Text;
Mail.Priority = MailPriority.High;

SmtpClient smtp = new SmtpClient("smtp.gmail.com");
smtp.Credentials = new System.Net.NetworkCredential("username", "password");
smtp.EnableSsl = true;
smtp.Send(Mail);

但是我遇到以下错误:
The requested address is not valid in its context 74.125.47.109:25

谁能给我发送正确的代码来解决此错误.

But I am getting following error:
The requested address is not valid in its context 74.125.47.109:25

Can anyone send me the proper code to resolve this error.

推荐答案

端口是否打开?防火墙权限到位了吗?
进一步确保已在Web.Config中配置SMTP配置:

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>

在将以下代码添加到web.config时出现错误

I am getting error on adding following code to web.config

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

错误是:
请求的地址在其上下文中无效74.125.65.109:25

请让我知道解决方案.

Error is :
The requested address is not valid in its context 74.125.65.109:25

Please let me know the solution for this.
