sender_canonical_maps is a property of the cleanup service, not smtp, so you can't override that setting here. > > 2. /etc/postfix/generic_toext > /^(.*)@(.*)myhostname\.com/ $1...@myexample.com You can probably use this same regexp with smtp_header_checks to achieve your goal. You /can/ use a custom smtp_header_checks setting in a master.cf smtp transport. http://www.postfix.org/postconf.5.html#smtp_header_checks -- Noel Jones
