perl: Amavisd-new Custom Hook to quarantine email to S3

We are using amavisd-new ([login to view URL]) to filter email. We use the SQL method to store the logging information, and we're currently using it to store the quarantined email (in the Quarantine table, as per the mysql documentation at [login to view URL] We would like to move storage for the quarantine (only) on to Amazon S3. Since amavisd-new support Custom Hooks, we would like to do a hook at the after_send or mail_done hook level, that would store the quarantined message in Amazon S3 storage. I'm looking for someone to write this custom hook. It needs to work with an unmodified version of amavisd-new 2.8.0 or later. We have busy mailservers that need to quarantine 10-15 messages per second, and we need to be sure we can keep up - this likely will require parallel multipart uploads.
