In the first section, you can choose how you want to Specify envelope recipients to match for this new rule:

• Single recipient: Filter messages directed to a specific address from your domain.
• Pattern match: Detect messages that match a specific pattern in your domain.
• Group membership: Messages directed to one of the groups in this domain.
• All recipients: All incoming messages to unknown addresses. This is great for catching emails sent to an incorrect address inside your domain.
