I have Postfix installed which I am using for SMTP only. It is configured for one of our client's domain and sending newsletters and notifications to the users.
The problem is that because the client owns the domain and receives mail for it, any time there is a message that is bounced or undeliverable, they receive the NDR. This is becoming a nuisance for them and they have asked us to disable sending of these NDR's.
Is it possible to do so? I believe the following parameters are relevant (taken from our current configuration):
notify_classes = resource, software
error_notice_recipient = postmaster
