I have e-mail notification alerts configured for various 3rd-party backup systems. These tend to send success or failure notifications as HTML format e-mail — with embedded links to jobs, logs, sites, etc.
[mail.ziggo.nl] automatically moves all of these to the SPAM folder.
I have tried to create various 'rules' in [mail.ziggo.nl], but these have never worked as expected.
Other than manually mark each e-mail notification as 'Not Spam' several times per day, is there any way to instruct [mail.ziggo.nl] to allow these important e-mail to be delivered to the INBOX without being marked as SPAM?
