Hi there! I have an exception in my senderemail program. here the code:

private void SendEmail(MailMessage message, MailAddress from)
{
message.Subject = txtTitle.Text;
message.SubjectEncoding = Encoding.UTF8;
message.BodyEncoding = Encoding.UTF8;
SmtpClient smtpClient = new SmtpClient(Properties.Settings.Default.SMTPServer);
smtpClient.EnableSsl = false;
smtpClient.UseDefaultCredentials = false;
smtpClient.Credentials = new NetworkCredential();
try
{
smtpClient.Send(message);

        }
        catch (Exception ex)
        {
           throw new Exception(ex.Message);
        }
        finally
        {
            message.Dispose();
        }
    }

but in line "smtpClient.Send(message);" I have the following exception : System.Net.Mail.SmtpException: Failure sending mail. ---> System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: A socket operation was attempted to an unreachable network 74.112.253.35:25 at System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress) at System.Net.ServicePoint.ConnectSocketInternal(Boolean connectFailure, Socket s4, Socket s6, Socket& socket, IPAddress& address, ConnectSocketState state, IAsyncResult asyncResult, Int32 timeout, Exception& exception) --- End of inner exception stack trace --- at System.Net.ServicePoint.GetConnection(PooledStream PooledStream, Object owner, Boolean async, IPAddress& address, Socket& abortSocket, Socket& abortSocket6, Int32 timeout) at System.Net.PooledStream.Activate(Object owningObject, Boolean async, Int32 timeout, GeneralAsyncDelegate asyncCallback) at System.Net.PooledStream.Activate(Object owningObject, GeneralAsyncDelegate asyncCallback) at System.Net.ConnectionPool.GetConnection(Object owningObject, GeneralAsyncDelegate asyncCallback, Int32 creationTimeout) at System.Net.Mail.SmtpConnection.GetConnection(ServicePoint servicePoint) at System.Net.Mail.SmtpTransport.GetConnection(ServicePoint servicePoint) at System.Net.Mail.SmtpClient.GetConnection() at System.Net.Mail.SmtpClient.Send(MailMessage message) --- End of inner exception stack trace --- at System.Net.Mail.SmtpClient.Send(MailMessage message) at EmailSender.EmailSenderForm.SendEmail(MailMessage message, MailAddress from) i

1. check you can ping the mail server's ip address from your computer. 2) use telnet to connect to the ip and port to see if there is an email server there. *) try removing the ":25" from the address you are specifying.
