How to: SES Gotchas and Limitations
-	🔸**Internet Access:** SES SMTP endpoints are on the Internet and will not be accessible from a location without Internet access (e.g. a private subnet without NAT gateway route in the routing table). In such a case, set up an SMTP relay instance in a subnet with Internet access and configure your application to send emails to this SMTP relay instance rather than SES. The relay should have a [forwarding rule to send all emails to SES](http://docs.aws.amazon.com/ses/latest/DeveloperGuide/send-email-smtp-existing-server.html)). ❗If you are using a proxy instead of a NAT, confirm that your proxy service supports SMTP.
