In this part, you can see some of the options for modifying, tagging, or rerouting the message:

• Headers: A few selectable options of some pre-generated messages to the header or to create a custom one.
• Subject: Prepend a specific message to the subject.
• Route: Add this message to the normal route or a custom one.
• Envelope recipient: To change the recipient of the messages, equivalent to forwarding a copy of the message. When using this option, it's a good idea to also keep a copy of the original intended recipient using the custom headers.
• Spam: This will make this route accept emails tagged as spam.
• Attachments: Select this to remove attachments (highly recommended in most cases).
• Also deliver to:
  • Normal: Send a copy of the messages to a specific address. You can also use group addresses for this.
  • Advanced: This will allow you to send a copy using a custom route to create a sub-routing rule.
