Symptoms
When you write an SMTP event sink for use with Microsoft CommercialInternet System (MCIS) 2.0, you can use the IStream::Stat() interface toreturn the size of the message. The following code segment demonstratesthis:
HRESULT STDMETHODCALLTYPE CSmtpRules::OnDelivery(IMsg *pMsg){   IStream *pStream;   HRESULT hr;   hr = pMsg->GetInterfaceA("Msg Stream", IID_IStream, (IUnknown**)    &pStream);   if (SUCCEEDED(hr))   {      STATSTG stg;      if (S_OK == pStream->Stat(&stg, STATFLAG_NONAME))      {         sprintf(buffer, "Data size: %d - %d\r\n",         stg.cbSize.LowPart,         stg.cbSize.HighPart);      }      else   // report error}				

However, the Istream::Stat() call will return E_NOTIMPL.
Cause
This interface was not implemented in versions of Smtpsvc.dll prior to version 1877.11.

If you want to implement this feature, you must use this version or later and modify your code to call pStream->Stat(&statStg,STATFLAG_NONAME), and then retrieve the size information out of statStg.cbSize. This method cannot be used to retrieve file names, as files are only created after the sinks are called. After using pStream, you must call pStream->Release( ), or the message will be left in the queue after delivery.
