Postfix header_checks and body_checks are intended as a blunt instrument, and are very useful when a large hammer is needed. There is no bypass/whitelist mechanism, and unlikely one will be added in the future. For finer control, there are numerous content_filter, smtpd_proxy_filter, milters, and policy services that plug into postfix. > If this is not possible, could > this be a future feature of postfix, so that one doesn't depend on > 3rd party software? Postfix already depends on third-party software for pcre, hash/btree tables, SQL, SASL authentication, TLS, and on and on. -- Noel Jones
