'Include a copy' agent in mail file

We’ve been working with trying to create a simple actions agent to respond to anyone that sends email to an outgoing-only mailbox. This sends back a message saying ‘send your reply to the original sender’ and also includes the ‘include a copy of the original email’ action. However, this only inserts the ‘In response to’ boilerplate, and not the doc link it’s supposed to add. This runs on mail ‘after arrival’, I’ve tried it on ’ before arrival’, and have signed it by myself and also by the server. No go. (The mailbox is a ‘normal person’ mail file: iNotes5.) Thanks!
