Additional Information:
If you would like to proactively confirm that emails are being sent again, create a nas probe AO profile to send EMAIL to your own email address for some common alarms that you currently see in the alarm sub-console, e.g., for cdm and choose on 'overdue age' of 5 mins. Activate the nas AO profile and restart the nas. After you've received the email(s), make sure you deactivate the profile.
