问题描述
我想从我的asp.net Web应用程序发送一封邮件，这里我使用发往和发往该地址的邮件进行测试
我使用的是webmail.1and1.com.
我的系统中没有gmail，并且还没有配置smtp，
因此以下代码不起作用
I want to send a mail from my asp.net web application,here I am using same from and to address,for testing
I am using webmail.1and1.com for my outlook.
I am not having gmail in my system,and smtp also is not configured,
so the following code is not work
protected void btnsubmit_Click(object sender, EventArgs e)
{
Response.Write("you have applied" + ddl.SelectedItem.ToString());
System.Net.Mail.MailMessage mm = new System.Net.Mail.MailMessage();
mm.To.Add(new System.Net.Mail.MailAddress("[email protected]"));
mm.From = new System.Net.Mail.MailAddress("[email protected]");
mm.Sender = new System.Net.Mail.MailAddress("[email protected]");
mm.Subject = "Request for Leave";
mm.Body = txteno .Text+"request"+ddl.SelectedItem .ToString ()+"leave";
mm.IsBodyHtml = true;
mm.Priority = System.Net.Mail.MailPriority.High; // Set Priority to sending mail
System.Net.Mail.SmtpClient smtCliend = new System.Net.Mail.SmtpClient();
smtCliend.Host = "pop.1and1.com";
smtCliend.Port = 25; // smtp port no
smtCliend.Credentials = new NetworkCredential("User Name", "Password");
smtCliend.DeliveryMethod = System.Net.Mail.SmtpDeliveryMethod.Network;
try
{
smtCliend.Send(mm);
}
catch (System.Net.Mail.SmtpException ex)
{
lblmsg.Text = ex.ToString();
}
catch (Exception exe)
{
lblmsg.Text = "\n\n\n" + exe.ToString();
}
}
错误显示为，
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:无法建立连接，因为目标计算机在System.Net.Sockets.Socket上主动拒绝了System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot，SocketAddress socketAddress)上的74.208.5.5:25 System.Net.ServicePoint.ConnectSocketInternal上的.InternalConnect(EndPoint remoteEP)(布尔值connectFailure，Socket s4，Socket s6，Socket&套接字，IPAddress&地址，ConnectSocketState状态，IAsyncResult asyncResult，Int32超时，Exception&异常)内部异常堆栈跟踪---在System.Net.PooledStream.Activate(Object System.Net.PooledStream.Activate处的owningObject，布尔异步，Int32超时，GeneralAsyncDelegate asyncCallback)(System.Net.ConnectionPool.GetConnec处的ObjectowningObject，GeneralAsyncDelegate asyncCallback) System.Net.Mail.SmtpConnection.GetConnection(字符串主机，Int32端口)处的System.Net.Mail.SmtpTransport.GetConnection(字符串主机，Int32端口)处的tion(对象owningObject，GeneralAsyncDelegate asyncCallback，Int32 creationTimeout).
