**Your software**  
My Mautic version is: 4.4.7

**Your problem**  
My problem is: Only some bounced emails are being treated correctly by Mautic. I use Amazon SES and have SNS properly setup. For example: when I send the test email to [bounce@simulator.amazonses.com](mailto:bounce@simulator.amazonses.com) it DOES get the proper mark in Mautic.

However, several emails are not being properly marked as bounced. Everytime I send a campaign, I get dozens of messages like this one:

## Delivery Status Notification (Failure)

### [MAILER-DAEMON@amazonses.com](mailto:MAILER-DAEMON@amazonses.com)

An error occurred while trying to deliver the mail to the following recipients:  
[jon\*\*\*\*\*\*@gmail.com]

Not sure where to fix this, as it apparently is related to how Amazon SNS handles the bounces.

Thanks in advance!
