wrong question... you can remove the header that your postfix adds. use DISCARD in header_checks. but make sure to use a conservative pcre expression (one that only removes your header, and not headers added by other systems). if your goal is to hide your MTA. well, you can't. each piece of software has a "signature". you can put boxes in front of your MTA, but that's only a translation. postfix is a secure MTA. Don't try to hide. if you're not ready to fight, find another job.
