I created an email system using Amazon Simple Email Service (SES), which handles failures for invalid messages using Notification (SNS) and Queue (SQS). Sending letters to valid addresses works as expected, but I have a problem trying to report a failure.
There are 2 failure situations: the first works, and the second does not.
1) Sending a fake address in an existing Internet provider (for example, foo@gmail.com or foo2@yahoo.com ) - correctly bounces and sends a notification to my queue via SNS
2) After sending a fake address in a fake ISP (for example, gideon@rosenthal.com ), the queue does not receive rejections from the SNS.
However, a rebound is recognized at some AWS level because it is added to the Bounce-Statistics graph in the console.
I cannot remove these addresses from my list of email addresses if I am never notified that the message has bounced.
After a lot of research, I initially thought it was a problem with the AWS Suppression List, but I don’t think it is possible since I tried to send email addresses that were unlikely to be used in the last 12 days.
My other thought is soft bounce , and the system will only be updated if it continues to bounce over the next 12 hours.
