Once your master.cf file is correct, it is no longer of much interest. What matters now is logs and main.cf. > Now I get NDRs every minute or so because of those retrying emails. What > next? Once the notifications are sent, the associated message is deleted from the queue. If you're not generating new bounces every minute, the volume will dissipate. If you're generating a lot of bounces, that's the problem to solve, i.e. the *generating* part. Instead of working on throwing them away, find out why you have a high bounce rate and fix that. -- Viktor.
