What is the difference between an email configuration done through Spotlight Connection Manager and that done through Spotlight Console options?
To configure email settings for a connection, highlight the connection and select properties. Under the "Monitoring" tab, click the "E-mail" button.
For email configuration through Spotlight Console options, from the "View" menu, go to "Options | Spotlight Console and select Servers | Mail Server" .
The difference between the two email settings is, that for Server Connection property is used for setting up email notifications for a single server connection so that when the server becomes unavailable, you are automatically notified by email.
That in server options "View | Options | Spotlight Console | Servers", is used for email alerts and warnings based on the different alarms setup. This means that if this email notification is not set, you won't be able to get alerts and warnings for your servers. This configuration is for all your connections.
