I’ve set up email bouncing with Mailgun as described in Handling bouncing e-mails
Most bounces are handled by Mailgun and then processed through the Discourse API.
But some bounces are sent directly to the forum on the Return-Path address:
The forum receives these emails, but then seems to do nothing with them. In particular, the user’s bounce score is not increased.
Do I need to change any other settings to make this work?
