Fetch emails from Amazon S3 and feed to procmail

I just wanted to thank you for this script :) I have an unusual scenario where I have to forward certain emails to a specific domain to external email addresses (using the AWS recommended method with an S3 bucket and lambda), and others (to the same domain), process via postifx on an EC2 to users. Many hours of turning this over, and I was stumped. The notion of a script in this style just hadn't occurred to me. Now I have a catch-all rule that puts everything else incoming in the bucket, and your script feeds them into sendmail. Genius. Thank you again, Jamie
