One very interesting point of the SimpleMailWebEventProvider is that this class inherits from the BufferedWebEventProvider instead of from the WebEventProvider as the EventLogWebEventProvider does. Inheriting from the BufferedWebEventProvider means that you can have the health monitoring system build a collection of error notifications before sending them on. The bufferModes section defines how the buffering works. The aforementioned SimpleMailWebEventProvider does exactly what its name states it sends out a simple text-based e-mail. To send out a more artistically crafted e-mail that contains even more information you can use the TemplatedMailWebEventProvider. Just like the SimpleMailWebEventProvider you simply define the provider appropriately in the healthMonitoring section. The model for this is presented in Listing 12-19.
