I am getting thousands of bounced or failed messages to email@example.com from firstname.lastname@example.org. The only way to control it is to stop exim, delete the queue. When I start exim back up, in 30 minutes, the mail is back, bouncing so many I need to do it over again. How do I block bounced messages from him, or just plain stop any bounced messages from being delivered? Can the user nobody be set to fail or discard? Thanks for any help!
