Notifier and Publisher

The notifier and publisher are e-mail sender.

The notifier is executed before an update to notify (e-mail destinations) that an update will be performed. For instance, it can invite users to logout from an application and save their current work.

The publisher is executed after an update. It sends a complete update report, describing all actions performed by Kalumet and notifying if the update has been performed successfully or not.

Both notifier and publisher are configured in the same way. You define:

• a SMTP server (for instance mail.host.com)
• a sender address (for instance kalumet@host.com)
• and a set of e-mail destinations (for instance me@example.com)
• in the case of the notifier, you can define a countdown which is a "wait" between the notification e-mail and the beginning of the update.
