The problem is that we are getting multi-line responses from the server in two (or more) pieces. That means that the second piece of the response remains in the socket's read buffer. This causes the responseCode to be not the last one, this is the reason why are you getting this errors.

Here is a little bug fix, put replace the waitForResponse() with this:

void SmtpClient::waitForResponse() throw (ResponseTimeoutException)
{
    do {
        if (!socket->waitForReadyRead(responseTimeout))
        {
            emit smtpError(ResponseTimeoutError);
            throw ResponseTimeoutException();
        }

        while (socket->canReadLine()) {
            // Save the server's response
            responseText = socket->readLine();

            // Extract the respose code from the server's responce (first 3 digits)
            responseCode = responseText.left(3).toInt();

            if (responseCode / 100 == 4)
                emit smtpError(ServerError);

            if (responseCode / 100 == 5)
                emit smtpError(ClientError);

            if (responseText[3] == ' ') { return; }
        }
    } while (true);
}

I will commit this to the repo in the next days.
