Are there any examples of how the rules for the block and allow list can be designed?

You have the possibility to define your own rules for the filter, based on which a message can be accepted or blocked. To create such rules, you can find the menu items "Allow list filtering rules" or "Block list filtering rules" in the Admin panel under "Incoming - Protection settings" or "Outgoing - Protection settings".

Please note that for security reasons, no rules for allow list can be created for the outgoing filter.
