In this way, all incoming email, except email that comes from your contacts on the “Safe Senders” list, is sent to your spam folder. The “Safe Lists Only” option is the exact opposite in a sense.
This means that all incoming mail will only be sorted by domain names and email addresses that you have on your “Blocked Senders” list.
For example, the first option practically disables the automatic filter. This setting tells Outlook how you want to filter incoming email. You can choose one of the following options: No automatic filtering, Low, High, Safe lists only. There are a few additional settings you can play with to further customize your spam folder. Check the option “Permanently delete suspicious spam instead of moving it to the Spam folder.”.
