I know this is moving away from LC, but you can use a simple AppleScript to to do this, then trigger the AppleScript from Mail rules, or run as a standalone app, or you could trigger the AppleScript from LC if that’s what you need.
I’m no AppleScript expert, I just did a bit of searching and found a script that could be easily modified, anyway, this is the script I tested and it seems to do what you asked. It could probably be improved, if anyone understands AS better please step in. set toAddress to "myemailaddr...@mail.com" set toName to "My Name" set toSubject to "Something Cool" tell application "Mail" repeat with _acct in imap accounts --Look For Messages in the INBOX with the subject set in toSubject set _acct_name to name of _acct set _inbox to _acct's mailbox "INBOX" set _msgs_to_capture to (a reference to ¬ (every message of _inbox ¬ whose subject is toSubject)) repeat with _msg in _msgs_to_capture set _fwdmsg to forward _msg with opening window tell _fwdmsg make new to recipient at end of ¬ to recipients with properties {name:toName, address:toAddress} end tell activate send _fwdmsg end repeat end repeat end tell To compile this code, open Utilities > Script Editor, create a new script and paste the code in, make the changes you need to lines 1, 2 and 3 and save the script as an application in the User > Library > Application Scripts > com.apple.mail folder, then it will be available in the Apple Mail Rules.
