default_transport is a property of the trivial-rewrite service, not smtpd. http://www.postfix.org/qmgr.8.html http://www.postfix.org/trivial-rewrite.8.html http://www.postfix.org/smtpd.8.html If your output IP depends on the input IP, multiple postfix instances is the only reasonable solution. -- Noel Jones
