Hi there, I have another problem in my code, this is my code :

private void SendEmail(MailMessage message, MailAddress from)
{

        SmtpClient smtpClient = new SmtpClient("smtp.gmail.com", 587);
        smtpClient.EnableSsl = false;
        smtpClient.UseDefaultCredentials = false;

        smtpClient.Credentials = new NetworkCredential("someone@gmail.com", "password");

        try
        {
            smtpClient.Send(message);

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

and now I have following exception in line "smtpClient.Send(message)" : System.Net.Mail.SmtpException: Failure sending mail. ---> System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond 209.85.143.108:587 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) in is i

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

Hi there, I write a program trying to send email via my gmail account, here is the code:

MailMessage message = new MailMessage();
MailAddress sender = new MailAddress("username@gmail.com");

        message.Body = "just for test";
        message.From = sender;
        foreach (String strEmail in emailList)
        {
            MailAddress reciever = new MailAddress(strEmail);
            message.Bcc.Add(reciever);
        }
            
        message.Subject = "test";
        message.SubjectEncoding = Encoding.UTF8;
        message.BodyEncoding = Encoding.UTF8;


        SmtpClient smtpClient = new SmtpClient("smtp.gmail.com", 587);
        smtpClient.EnableSsl = true;
        smtpClient.UseDefaultCredentials = false;
        smtpClient.Credentials = new NetworkCredential("username@gmail.com","password");
        
            //  smtpClient.DeliveryMethod = SmtpDeliveryMethod.Network;
            try
            {
                smtpClient.Send(message);

            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.ToString());
                throw new Exception(ex.Message);
            }
            finally
            {
