Hello all,
I am trying to create an event handler which will notify me everytime a user sends a mail message exceeding 10 MB. Is that possible? I have tried looking into the different options but none give me the possibility of specifying the message threshold.
Thank you.

I think you could use the extension manager with the function: EM_MAILSENDNOTE.

Hi Mr Goudvis,
Thank you very much for your response. Could you please elaborate on the extenion manager method. If I understand correctly, it cannot be achieved using event generator??
Do I have to write code to be able to achieve this?
Thank you for your help.

The extension manager allows you write, in C/C++, your own functions that will hook in a Notes function. It requires the C API toolkit. Here is a sample:
STATUS LNPUBLIC _export EMHandlerProc( EMRECORD FAR * theData )
{
VARARG_PTR argPtr;
DBHANDLE dbHandle;
STATUS error;
DBID dbID;
USHORT retMode;
argPtr = theData->Ap;
/* do nothing if there is an error. */
if ( theData->Status )
{
goto EXIT;
}
switch (theData->EId)
{
case EM_NSFDBCLOSE:
/*
if database is opened then clear the flag when the close
function is called on the database.
*/
if ( gGotMyDatabase == FALSE ) break;
dbHandle = VARARG_GET( argPtr, DBHANDLE );
if (theData->NotificationType == EM_BEFORE)
{
if ( dbHandle )
{
NSFDbIDGet( dbHandle, &dbID );
if ( EQUAL_DBID(gtheID,dbID) )
{
gGotMyDatabase = FALSE;
}
}
}
break;
case EM_NSFDBOPENEXTENDED:
/*
don't handle any of the hooks until my database is opened,
and be sure to ignore the hooks when my database is closed.
*/
if ( gGotMyDatabase == TRUE ) break;
VARARG_GET( argPtr, char FAR * );
VARARG_GET( argPtr, WORD );
VARARG_GET( argPtr, HANDLE );
VARARG_GET( argPtr, TIMEDATE FAR * );
dbHandle = *( DBHANDLE FAR * )VARARG_GET( argPtr, DBHANDLE FAR *);
if (theData->NotificationType == EM_BEFORE)
{
if ( dbHandle )
{
/* check to see if i got a db handle! */
error = NSFDbModeGet( dbHandle, &retMode );
if ( !error && (retMode & DB_LOADED) )
{
NSFDbIDGet( dbHandle, &dbID );
if ( EQUAL_DBID(gtheID,dbID) )
{
gGotMyDatabase = TRUE;
}
}
}
}
break;
} /* END SWITCH */
/*
if being notified before then always continue onward ignoring
the error if not it is possible to return a status code to
change the program flow.
*/
EXIT:
if ( theData && theData->NotificationType == EM_BEFORE )
return( ERR_EM_CONTINUE );
else
return( theData->Status );
}

Dear Mr Goudvis,
Thank you for your response. I will try to look into the code. It seems awfully complicated 
Thank you for your help.
