我想从服务器发送邮件，我使用了以下代码，但是会产生以下错误，请给我解决方案以进行纠正

使用的代码:

I want to send a mail from my server, i used the following code but it produces the following error, kindly give me solution to correct it

Code Used:

string s = "kishore";
MailMessage mail = new MailMessage();
mail.To = "[e-mail]";
mail.From = "[e-mail]";
mail.Subject = "House Boat Cruise";
mail.BodyFormat = MailFormat.Html;
mail.Body = s;
SmtpMail.SmtpServer = "mail.keratravels.com";
SmtpMail.Send(mail);
lblDisplay.Text = "Successfully Posted";

错误:
服务器拒绝了一个或多个收件人地址.服务器响应为:503尝试发送到非本地电子邮件地址时，此邮件服务器需要身份验证.请检查您的邮件客户端设置，或与管理员联系以验证是否为此服务器定义了域或地址.

ERROR:
The server rejected one or more recipient addresses. The server response was: 503 This mail server requires authentication when attempting to send to a non-local e-mail address. Please check your mail client settings or contact your administrator to verify that the domain or address is defined for this server.

推荐答案

该错误不言自明.您尚未提供用于访问帐户的身份验证用户名/密码.

您需要进行Web.Config更改.
在这里查看:在ASP.NET 2.0中发送电子邮件 [

The error is self explanatory. You have not provided the Authenticating Username/Password that will be used in order to access the account.

You need to make Web.Config changes.
Have a look here: Sending Email in ASP.NET 2.0 [^]
Something like:

<configuration>
  <!-- Add the email settings to the <system.net> element -->
  <system.net>
    <mailSettings>
      <smtp>
        <network

             host="relayServerHostname"

             port="portNumber"

             userName="username"

             password="password" />
      </smtp>
    </mailSettings>
  </system.net>
  <system.web>
    ...
  </system.web>
</configuration>
