CdoEventStatus Enum
Topic Last Modified: 2006-06-13
The CdoEventStatus enumeration is used when implementing a transport event sink using Collaboration Data Objects (CDO). The second argument to the various event interface methods, such as OnArrival Method and OnPost Method, is set to this enumeration type. Event sinks signal to the event source whether to continue running subsequent sinks, or to skip all remaining sinks and return.

Remarks
SMTP and Network News Transfer Protocol (NNTP) transport event sinks are processed by the event source in serialized fashion. In other words, each sink has a priority relative to others for a particular event, and the sinks are notified one at a time. The event source proceeds from the highest priority sink to the lowest, and for each sink, it checks the returned CdoEventStatus value. If the sink sets the value to cdoSkipRemainingSinks, then the event source does not proceed to notify any lower priority (remaining) sinks.
