There are many ways to handle bounces that come from CiviCRM. Below is one way of doing it. Using this way we set up an e-mail account that takes bounce e-mails from Amazon SNS. We then use the script below to read the e-mails from the e-mail account and add them to the do not follow list on CiviCRM. As with all wild code, we guarantee nothing, it works for us, it might not work for you Amazon SES bounce process for CiviCRM using IMAP. Redirect your bounce messages to an e-mail address and then use this to process that. Very useful.
