Email Information to Provide

When you access Amazon SES through the SMTP interface, your SMTP client application assembles the message, so the information you need to provide depends on the application you are using. At a minimum, the SMTP exchange between a client and a server requires a source address, a destination address, and message data.

If you are using the SMTP interface and have feedback forwarding enabled, then your bounces, complaints, and delivery notifications are sent to the "MAIL FROM" address. Any "Reply-To" address that you specify is not used.
