Script to download IMAP sent email headers - repost

A script that allows a user to enter their IMAP account details. So username / password / server address / port. The script then goes and fetches the email headers from their sent mail folder. Key information to capture is To / From / Date-Time. The script then keeps the header data stored in a csv / text type file for further analysis which isn't part of this project. If this can then be scheduled to run every day, that would be good. Only the raw data is required. I would prefer the script to run on a Windows 7 install initially as I'm only after functionality.
