The above line may be added after any smtpd service in master.cf, and must be indented. http://www.postfix.org/smtpd.8.html > 2.) subcleanup unix n - - - 0 cleanup This line can be added anywhere in master.cf, followed by indented options accepted by cleanup(8), such as " -o header_checks=....." http://www.postfix.org/cleanup.8.html > 3.) -o smtp_header_checks=regexp:/etc/postfix/header_checks smtp_header_checks are a property of the smtp(8) delivery transport. As such, it can be added after any "smtp" transport in master.cf. http://www.postfix.org/smtp.8.html Some things to keep in mind... - only one action is allowed per header. If a header matches multiple lines in your header_checks file, only the first match is performed. - You can have postfix log all the headers it examines with a header_check like: /./ INFO Note this prevents any further matches from being processed (one action per header). - postfix does see headers added by milters, see mime_header_checks (default value $header_checks). - postfix does not see headers added after postfix has received the mail, such as headers added by downstream content filters or a next-hop relay. - read the documentation! Great effort has been put into documenting postfix clearly and correctly. http://www.postfix.org/documentation.html http://www.postfix.org/header_checks.5.html http://www.postfix.org/postconf.5.html (for main.cf syntax) http://www.postfix.org/master.5.html (for master.cf syntax) -- Noel Jones
