AWS SES S3 process inbound email

Question

I'm working on a publish by email system based on AWS SES. For all incoming emails I've set routing to save messages in an S3 bucket so I can asynchronously process them. The problem I have is that the messages are saved in the S3 bucket in a raw format: headers, email body, etc + the encrypted attachment (a huge string) - all in a single file.

Is there a way to break the email message apart form the attachment and save both in separate files at AWS SES level? I'm trying to get the data in the format I need straight from AWS and avoid adding another processing step to the process.

If AWS SES doesn't provide such a feature, what would be the proper way to process these messages to obtain the result described above?

It doesn't look possible to have SES automatically split up the email for you. As per the documentation here:

Amazon SES provides you the raw, unmodified email, which is typically in Multipurpose Internet Mail Extensions (MIME) format.

I would use S3 or SNS to trigger a Lambda function whenever SES puts a new email file to S3. The Lambda function could split the file however you wish, then write those new files to another S3 bucket.
