    Unhappy SMTP Error

    Hello,
    I had written a programme in VC++ for sending the mails using SMTP.
    It sends the mails to and from the particular domain only.
    I want to send the mail using Rediffmail or Gmail . But its not possible.

    Foll. are the settings for sending the mail from Rediffmail :
    SmtpServerName = smtp.rediffmail.com
    SmtpServerPort = 25

    If i run the prog. it gives the foll. error for :
    <Code>
    CString sTo;
    sTo.Format( _T( "RCPT TO: <%s>\r\n" ), "xxxxx@gmail.com");
    m_wsSMTPServer.Send( (LPCTSTR)sTo, sTo.GetLength() );
    </Code>

    m_wsSMTPServer is a object of CSocket.

    The Error is :

    421 Authorization failed: please authenticate by doing get message first

    So for this error I had added Authentication by using following :
    <Code>
    //////Check for authentication
    sLogIn.Format( _T( "AUTH LOGIN: <%s><%s>\r\n" ), "abc@rediffmail.com", "12Xy3z");
    m_wsSMTPServer.Send( (LPCTSTR)sLogIn, sLogIn.GetLength() );
    </Code>

    here it give the foll. error :

    502 unimplemented (#5.5.1).

    I really stuck here .I searched a lot, but not succeeded. Any kind of help is much appreciated.

    Thanking you in anticipation.
