You are, of course, correct. It would be totally retarded to be able to switch of bounce/ndr messages. Mail admins are totally perfect and never make any config errors that would have the potential to turn Postfix into a bulk backscatter machine. I apologise for asking for such a stupid feature. I'll try and become perfect so I don't show up any limitations to your Postfix in the future. I also apologise for asking for the ability to white list clients, senders or recipients in the header and body check section. That is also totally retarded of me and I will ask all spammers to be considerate and send me 'the right kind of spam'. :-)
