Email notifications appear to work but must be used with the heirloom mailx implementation.
|
||||
The BSD and GNU implementations didn't appear to work with Exchange or the ETS smtp server for
|
||||
whatever reason but the heirloom mailx binary works just fine. The advantage is that the smtp
|
||||
server can be explicitly specified rather than infered from mx records.

|
||||
The idea is that instead of sending an email notification, it should write a trigger file
|
||||
so the next time the sript runs, if there is need to send a notification and that file
|
||||
exists, the notifications will be sent. This will cut down on getting an email every time
|
||||
the application is starting up or reindexing the content database.
|
||||
</p>
|
||||
<p>
|
||||
Notifications are now only sent the second time that any given thresholds are broken.
