Bounce Handling with Amazon SES/SNS
I've created an extension to handle bounces through Amazon SNS notifications, see civicrm-ses.

It exposes a webhook to process SNS notifications and map and create bounces when appropriate.

Hope you find it useful.

PS: although the extension is in alpha stage, I've been using it in production for a month (~60,000 emails processed), test in a dev environment first if you like :)
