You'll can try replacing 'forward' with 'redirect': redirect sends the email to the new recipient exactly like the old forward sends a quoted version. in the final version you'll want to delete the 'with opening window' phrase (so that the emails are generated invisibly in the background) and uncomment the 'send' line (so that the emails are sent automatically). This is a testing version, where the email pops up so you can see what it looks like before it gets sent. SetlastForwardingDate to date sent ofmessageToForward PropertylastForwardingDate : ( current date ) the script itself would look something like this: That runs the script once a day at 6:00 pm. the launchd plist looks soemthing like this (save it as ): That requires two components: a launchd plist (which goes in ~/Library/LaunchAgents or /Library/LaunchAgents) and a script file (which can go anywhere, but /Library/Scripts would be conventional). Look, if I were going to do what you're trying to do, I would stop fiddling with rules and set up a launch agent that would periodically (once a day, once an hour, whatever your needs are) forward all unforwarded emails to the people they need to be forwarded to.
