  private void button1_Click(object sender, EventArgs e)
        {
            
            ReadIMAPEmail();
        }
        
        private void ReadIMAPEmail()
        {
            string Mailserver = ConfigurationSettings.AppSettings["MailServer"];
            string MailServerPort = ConfigurationSettings.AppSettings["MailServerPort"];
            string MailServerUsername = ConfigurationSettings.AppSettings["MailServerUsername"];
            string MailServerPwd = ConfigurationSettings.AppSettings["MailServerPwd"];
            ImapClient imap = new ImapClient(Mailserver, Convert.ToInt32(MailServerPort), true);
            imap.IsDebug = true;
            try
            {
                WriteEventLogEntry("Checking for Server Authentication....");
                if (imap.Connection())
//Iam getting the error message here after trying to connect to the server on particar port.But when i verified using telnet it is opening on that port

                {
                    WriteLog("Loggin in to IMAP server.", Color.Green);
                    
                    bool Islogin = imap.LogIn(MailServerUsername, MailServerPwd);
                    if (Islogin)
                    {
                        
                        WriteLog("Connected to IMAP server.", Color.Green);
