NAME
       ExportedMsg -- Mark a message as being successfully exported.

   SYNOPSIS
       ExportedMsg( login, msgNum )
                     D2      D3

       VOID ExportedMsg( LONG, LONG );

   FUNCTION
         Tells  the  MBP  that  a message has been successfully exported.
       The  MBP  uses  this  information  to prevent other exporters from
       wrongly  exporting  this message a second time or writing a bounce
       message.

         Every  exporter that exports a message from the local UMS system
       to  any  other system or network MUST call either ExportedMsg() or
        CannotExport()  for  each message it has processed.  This is valid
       for  private  messages as well as for public messages (news).  The
       MBP will decide what has to be done in any of these cases.

   INPUTS
       msgNum - Number of the exported message.

   NOTES
         This function may only be called by exporters.
