One of my clients sends mail using a custom application which *cannot* recognize a smtpd error message .. like user-not-found, or invalid-domain etc Now they want our postfix server to accept all mails without checks and send NDR's for undeliverable mails.
Can I write a special transport in postfix to simply accept the mail and bounce back for some addresses. So that I waste none of my servers processing for trying to even deliver these messages for eg I would like to have a transport map file like this /@hoatmail.com$/ accept_and_bounce:[127.0.0.1]
