The Wrapper is able to send out alert emails to in response to certain events.
See the documentation of individual properties for details on their use.

Example (send email in response to JVM restarts):
    # Common Event Email settings.
    #wrapper.event.default.email.debug=TRUE
    wrapper.event.default.email.smtp.host=smtp.mycompany.com
    wrapper.event.default.email.smtp.port=25
    wrapper.event.default.email.subject=[%WRAPPER_HOSTNAME%:%WRAPPER_NAME%:%WRAPPER_EVENT_NAME%] Event Notification
    wrapper.event.default.email.sender=myapp-noreply@mycompany.com
    wrapper.event.default.email.recipient=myapp-admin@mycompany.com
    # Event specific settings.
    wrapper.event.jvm_restart.email=TRUE
    wrapper.event.jvm_restart.email.body=The JVM was restarted.\n\nPlease check on its status.\n

The properties are all of the form `wrapper.event.<x>.email*`
where `x` is one of the "Event Types" defined above or the keyword `default`.

Whenever a property is not specifically defined for any of the event names,
the `default` value will be used. This is useful for setting values which will be common to all event emails.
