The following guidelines apply when you use Easy DKIM to authenticate your email:
Only the domain that appears in your "From" address needs to be configured for Easy DKIM. For domains that you use in "Return-Path" or "Reply-to" addresses, Simple DKIM is not required to be configured.
A number of AWS Regions provide Amazon SES. To ensure that all of your emails are DKIM-signed, you must finish the Easy DKIM setup process in each of the AWS Regions that you use to send an email.
Unless you set up Easy DKIM for specific subdomains when you verify a domain, your Easy DKIM settings also apply to all of that domain's subdomains.
Amazon SES applies Easy DKIM settings in the following manner if you configure Easy DKIM for a parent domain, a subdomain, and an email address:
DKIM subdomain settings take precedence over parent domain settings.
DKIM settings for an email address take precedence over those for the parent domain and, if relevant, the subdomain.
Simple DKIM configuration for a domain:
Go to https://console.aws.amazon.com/ses/ to launch the Amazon SES console.
Choose Domains from the Identity Management section of the navigation pane.
From the list of domains, select the one for which you wish to configure Easy DKIM.
Note : Check out the instructions for Verifying a domain with Amazon SES if you haven't started the domain's verification process yet.
Choose to Create DKIM Settings under DKIM.
