AWS-SES-simple-mail-forward

If you are starting a new project in AWS it is sometimes necessary to have a working email (to validate certificates from ACM for example). You can set your MX records to one of external mail hosting services but the option for custom domains is usually not free or with limited features.

Other option is to set AWS SES Email receiving rule.

How to

Set up SNS
- SNS > Create topic > Enter "email-forwarding" or name of your choice for topic name
Set up SES
SES > Email receiving > Rule Sets > Create rule set (or "View Active Rule Set" if you already have one in place)
Enter name for your rule set > "Create a Rule Set"
Click on your rule set > Create Rule
Enter your email address or string that matches many addresses (instructions are on that page) > Add recipient email
Click on "Verify domain" > AWS will ask you to make changes in Route53 > Next Step
