Amazon SNS bounce reports not working since January

I have a pretty big community and email notifications are a crucial part of our forum. However, since January (I guess due to an upgrade in Discourse) we no longer are receiving Amazon SNS bounce reports displayed in the Discourse Email Bounces section and our Amazon SES bounce scoring is getting worse due to the fact that the Discourse instance keeps emailing invalid emails even though Amazon SES gets bounce reports but it doesn’t seem to relay them to the Discourse instance.

Is anyone else having similar issues? I am using AWS SES SNS topics for Bounce and Complains and everything worked properly up until January.

Any feedback would be much appreciated.

So you’ve been doing what is described at Configuring AWS SES for outgoing, bounce, and incoming email?
