我的代码如下...

My code is as follows...

//web .config code

 <system.net>
    <mailSettings>
      <smtp from="[e-mail]" >
        <network host="mail.enefinder.com" port="26" userName="username" password="password"/>
      </smtp>
    </mailSettings>
  </system.net>

//.........

MailMessage mail = new MailMessage();
            SmtpClient SmtpServer = new SmtpClient("mail.enefinder.com");
            mail.From = new MailAddress("[e-mail]");
            mail.To.Add("[e-mail]");
            mail.Subject = "enefinder";
            mail.Body = "mail with attachment";

            //System.Net.Mail.Attachment attachment;
            //attachment = new System.Net.Mail.Attachment("you attachment file");
            //mail.Attachments.Add(attachment);

            SmtpServer.Port = 26;
            SmtpServer.Credentials = new System.Net.NetworkCredential("username", "password");
            SmtpServer.EnableSsl = true;

            SmtpServer.Send(mail);
            Response.Write("mail send");
        }
        catch (Exception ex)
        {
            Response.Write(ex.ToString());
        }

Thanks in advance!

推荐答案

好，您使用了邮件服务器，并收到一条错误消息，告诉您该服务器未响应.您需要告诉我们的是，为什么您不相信该错误就表示它的确切含义.您是否检查了服务器上的防火墙?

Well, you used a mail server and got an error message telling you that this server did not respond. What you need to tell us, is why you don''t believe the error to mean exactly what it says. Did you check your firewall on your server ?

.net新代码中的任何错误

is anything wrong in code im new to .net

System.Net.Mail.MailMessage Email =新的System.Net.Mail.MailMessage(fromEmail，toEmail);
Email.Subject =测试主题";
Email.Body =这是一个测试";
System.Net.Mail.SmtpClient mailClient =新的System.Net.Mail.SmtpClient();
System.Net.NetworkCredential basicAuthenticationInfo =新System.Net.NetworkCredential(FromEmailAdd，PassWord);
mailClient.Host = smtpserver;
mailClient.UseDefaultCredentials = false;
mailClient.Credentials = basicAuthenticationInfo;
mailClient.Send(Email);

System.Net.Mail.MailMessage Email = new System.Net.Mail.MailMessage(fromEmail, toEmail);
Email.Subject = "test subject";
Email.Body = "this is a test";
System.Net.Mail.SmtpClient mailClient = new System.Net.Mail.SmtpClient();
System.Net.NetworkCredential basicAuthenticationInfo = new System.Net.NetworkCredential(FromEmailAdd, PassWord);
