Applescript stopped working after Mountain Lion upgrade

Question

Hi after upgrading to Mountain Lion (ML) the applescript that I use to reply to certain emails has stoped working on incoming emails. I have the script in the "new" correct folder. The funny thing is that the script works when you "apply rules" from the messages dropdown menu.

Answer 1

This is the script:
using terms from application "Mail"
          on perform mail action with messages theMessages for rule theRule
  --tell application "Mail"
                    repeat with eachMessage in theMessages
  --set theContent to content of eachMessage
                              set emailFrom to extract address from sender of eachMessage
                              try
  --set AppleScript's text item delimiters to {"(", ")"}
  --set contentParts to (every text item in theContent) as list
  --set AppleScript's text item delimiters to ""
  --set emailOnly to item 2 of contentParts
  --set recipientAddress to emailOnly
                                        set recipientAddress to emailFrom
                                        set theSubject to "Text for subject"
                                        set theSignature to signature "One"
                                        set theSendContent to " "
                                        set theSender to "[email protected]"
                                        set theMessage to make new outgoing message with properties {subject:theSubject, content:theSendContent, sender:theSender, visible:true}
                                        tell theMessage
  make new to recipient with properties {address:recipientAddress}
                                                  set message signature to theSignature
                                                  send
                                        end tell
                              end try
                    end repeat
  --end tell
          end perform mail action with messages
end using terms from
