How to move Mail.app messages with AppleScript

Question

I have the following AppleScrip to move all Mail messages from one folder to another folder:
on run {input, parameters}
          tell application "Mail"
                    repeat with theMessage in {messages in mailbox "Later" of account "[email protected]"}
                              set theMailbox to mailbox "INBOX" of account "[email protected]"
  move theMessage to theMailbox
                    end repeat
          end tell
          return input
end run
When I run the script, it gives an error message:
Syntax Error. Mail got an error: Can't make {message id xxx} of mailbox "Later" of account "[email protected]" into type scpcifier.
What do I have to change to make this script work?

Answer 1

What you are trying to do, move mail messages older than some time to a different folder, isn't really something that should be down by a rule. Rules are meant to examine messages as they arreive and to prefrom some action based on the mesage.
You would do better to make this a straight AppleScript that you would then run as needed or triggered by something like iCal on a daily basis.
