AppleScript Needed for reply-to heading replys

Question

I need help editing this script to reply to multiple emails I get from PayPal that will reply to the email's Reply-To Heading, not the From Heading, which of course is PayPal.
This script works for everything but replying to the return path (Reply-To) address.
Thank you in advance:
set thesenders to {}
set thesenderstext to ""
tell application "Mail"
          set themessage to the selection
          repeat with i from 1 to the number of items in themessage
                    set thesender to (extract address from (the sender of (item i of themessage)))
                    if thesenders does not contain thesender then
                              set thesenders to thesenders & {thesender}
                    end if
                    set the was replied to of (item i of the themessage) to true
          end repeat
          set AppleScript's text item delimiters to ", "
          set thesenderstext to thesenders as rich text
          set AppleScript's text item delimiters to ""
          set newMessage to make new outgoing message
          tell newMessage
                    set visible to true
  make new bcc recipient with properties {address:thesenderstext}
          end tell
          set toAddress to email addresses of item 1 of accounts as rich text
          tell newMessage
  make new to recipient with properties {address:toAddress}
          end tell
  activate
end tell

Answer 1

Try something like the following
                                        set theReplyTo to extract name from reply to of theMessage
                                        set theReplyToAddress to extract address from reply to of theMessage
Note: It looks like it will automatically use the From address if there is no Reply-To header line. If the Reply-To line has now name to go with the address then the name seems to be filled in with the Reply-to address.
