Hello community We are trying to set up a Mautic instance with SES and bounce managament from SNS with Amazon Web Services. We followed the instructions here carefully; [https://docs.mautic.org/en/channels/emails/bounce-management](https://docs.mautic.org/en/channels/emails/bounce-management) Amazon gives a confirmed on the subscription and we set up the notifications both on the domain and the e-mail we are using to send the mails. We are testing using SES sandbox accounts; [https://docs.aws.amazon.com/ses/latest/DeveloperGuide/send-email-simulator.html](https://docs.aws.amazon.com/ses/latest/DeveloperGuide/send-email-simulator.html) with [bounce@simulator.amazonses.com](mailto:bounce@simulator.amazonses.com). Yet the bounces don’t get recorded by Mautic. Can anyone help us troubleshout this problem? Some extra information: - When we visit /mailer/amazon/callback we get a 500 server error. I don’t know if that’s normal behaviour since it’s a callback url. - We are on mautic 2.16.2 or 2.16.3 - The Mautic instance is hosted in another AWS region than the SES and SNS. - We are testing the bounces by sending a mail from channels \> e-mails to a test user with the e-mailadres; [bounce@simulator.amazonses.com](mailto:bounce@simulator.amazonses.com) - When checking the logfile I’m seeing 2 errors: Type error: Argument 1 passed to Mautic\EmailBundle\Swiftmailer\Transport\AmazonTransport::processJsonPayload() must be of the type array, null given, called in /var/www/html/app/bundles/EmailBundle/Swiftmailer/Transport/AmazonTransport.php on line 103 And PHP Notice - SessionHandler::gc(): ps\_files\_cleanup\_dir: opendir(/var/lib/php/sessions) failed: Permission denied (13) - in file /var/www/html/vendor/symfony/http-foundation/Session/Storage/Proxy/SessionHandlerProxy.php - at line 86 {“maxlifetime”:1440} ---

Why not start with Mautic 3.x? Check email settings to ensure you are not using the “other smtp” selection with Amazon . Select Amazon specifically. A quick forum search gave me this: > [@New help with bounce management](https://forum.mautic.org/t/new-help-with-bounce-management/12831/11): > > The problem: > i forgot to choose my SNS-Subscription in SES under E-mail-adresses \> [mydomain.com](http://mydomain.com) \> Notifications \> edit configuration \> Bounces/complaints > > I had it set up for Domains-tab, but i forgot to do it for e-mail-tab too. ---

Are you using Amazon SES - SMPT or Amazon - API. for the connection? The SNS does not work with the API from what I can work out. ---

I think it does. Check this: > [@3.1.0: SES API working but not SNS (404 /worker/amazon/callback)](https://forum.mautic.org/t/3-1-0-ses-api-working-but-not-sns-404-worker-amazon-callback/15832/7): > > Why is it a different endpoint? Does SNS feedback loop give a different webhook if you send emails via API not SMTP? ---

> [@EJL](#): > > specifically Hi @joeyk , I am working with Amazon API, I have set up subscribers as my email and also the webhook. I can also confirm that mautic:email:fetch is indeed working and reading all my mails regarding bounces that I received from sns, but still it is not marking the contact as do not contact and not showing bounced
