MAIL FROM Domain Setup States with Amazon SES

After you configure an identity to use a custom MAIL FROM domain, the state of the setup is "pending" while Amazon SES attempts to detect the required MX record in your DNS settings. The state then changes depending on whether Amazon SES detects the MX record. The following table describes the email-sending behavior, and the Amazon SES actions associated with each state. Each time the state changes, Amazon SES sends a notification to the email address associated with your AWS account.

State Email Sending Behavior Amazon SES Actions
