If you are talking about Exchange server there is a web service of Exchange 2007 sp2, if you are talking about pop3 mail server you can try connecting to server by simulating telnet from your application and delete mail.

Everything seems ok. Could you pls send the SendCommandSynchronous method

[khosnur]

thanks again for reply.. here is the method: private MAIL_ERROR SendCommandSynchronous(string cmd, out string response, bool bMultiLineResponse) { // Remove any data that was left over on the buffer string deadData = _conn.Receive(); _conn.Send(cmd); response = WaitForResponse(bMultiLineResponse); return MAIL_ERROR.ERROR_NONE; } private string WaitForResponse(bool bMultiLine) { int timeout = 5000; // wait 10 seconds for response int waitedTime = 0; string strRet = ""; while (waitedTime < timeout) { System.Threading.Thread.Sleep(_TimeOut); strRet += _conn.Receive(); if (CommandComplete(strRet, bMultiLine) == true) { return strRet; } waitedTime += _TimeOut; } return strRet; }

Could you try

    private string GetResponse()
    {

        //read till finding new line, return.

        string strPrev = null;

        string strCurrent = null;

        string strMessage = null;

        NetworkStream ns = default(NetworkStream);

        ns = client.GetStream;//Previously instanced and connected TcpClient

        while (true)
        {

            byte\[\] buffer = new byte\[1\];
            //read by 1 byte 1 byte

            ns.Read(buffer, 0, buffer.Length);

            strCurrent = System.Text.Encoding.GetEncoding(1254).GetString(buffer);

            strMessage = strMessage + strCurrent;

            if (strCurrent == @"\\r" && strPrev == @"\\n")
            {

                break; // TODO: might not be correct. Was : Exit While
            }


            strPrev = strCurrent;
        }


        return strMessage;
    }

    private void SendMessage(string str)
    {

        str = str + "\\r\\n";
        //Controlchars.CrLf '10+13

        byte\[\] buffer = System.Text.Encoding.GetEncoding(1254).GetBytes(str);

        NetworkStream ns = client.GetStream;


        ns.Write(buffer, 0, buffer.Length);
    }
