AWS SES mailbox simulator
|Successful delivery—The recipient's email provider accepts your email. If you set up delivery notifications as described in Setting up event notification for Amazon SES, Amazon SES sends you a delivery notification through Amazon Simple Notification Service (Amazon SNS).
|Bounce—The recipient's email provider rejects your email with an SMTP 550 5.1.1 ("Unknown User") response code. Amazon SES generates a bounce notification and, depending on how you set up your account, sends it to you in an email or sends a notification to an Amazon SNS topic. The mailbox simulator email address isn't placed on the Amazon SES suppression list, which would normally happen when a hard bounce occurs. The bounce response that you receive from the mailbox simulator is compliant with RFC 3464
|Automatic responses—The recipient's email provider accepts your email and delivers it to the recipient’s inbox. The email provider sends an automatic response, such as an "out of the office" (OOTO) message, to the address in the Return-Path header of the email, or the envelope sender ("MAIL FROM") address if the Return-Path header isn't present. The automatic response that you receive from the mailbox simulator is compliant with RFC 3834
|Complaint—The recipient's email provider accepts your email and delivers it to the recipient’s inbox. The recipient decides that your message is unsolicited and clicks "Mark as Spam" in his or her email client. Amazon SES then forwards the complaint notification to you by email or by notifying an Amazon SNS topic, depending on how you set up your account. The complaint response that you receive from the mailbox simulator is compliant with RFC 5965
|Recipient address on suppression list—Amazon SES generates a hard bounce as if the recipient's address is on the global suppression list.
