An adapter that wraps Swoosh.Adapters.AmazonSES to use credentials from ExAws.

You may prefer this adapter to Swoosh.Adapters.AmazonSES if you have already configured ExAws for your project and are using instance role credentials.

This allows you to use automatically managed, short-lived credentials, rather than provisioning a static access key / secret key pair.

  region: "us-east-1"
