Write SES Bounces to S3

Implements a lambda function that handles SES email bounces via SNS.

Prerequisites (IAM)

An IAM role with the following policy is required as the execution role for the lambda function

(ses-bounces refers to the AWS bucket name)

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "logs:CreateLogGroup",
                "logs:CreateLogStream",
                "logs:PutLogEvents"
            ],
            "Resource": "arn:aws:logs:*:*:*"
        },
        {
            "Effect": "Allow",
            "Action": [
                "s3:PutObject"
            ],
            "Resource": [
                "arn:aws:s3:::ses-bounces/*"
            ]
        }
    ]
}

Setup (AWS)

1. Setup a SNS topic to receive bounce notifications

2. Setup a lambda function triggered by this SNS topic

3. Run npm install

4. Zip the contents (including node_modules) of this repo and upload it (see Function package in image)

5. Set the AWS_BUCKET environment varaiable to the AWS bucket you want to save bounce logs to

6. Set the handler to index.sesBounceHandler

7. Create a new IAM role or select one with the policy shown above (Prerequisites (IAM))

8. To ensure sufficient time to execute (save to S3) increase the timeout to 30s

9. You are good to go
