That's referring to an external content_filter; not part of postfix. The docs would be included with whichever content filter you picked. Kind of a useless suggestion, header_checks are quite capable of this. > I assume it's not a good idea to IGNORE all headers. Which can be > ignored? Make your header_checks rule as specific to the header you want to remove as possible, at a minimum specify the expected hostname and IP. It's important to not unintentionally remove other headers. Something like (all one line, beware wrapping): /^Recieived: .*\(host\.example\.com \[192\.168\.1\.100\]\)[[:space:]]+by server\.example\.com/ IGNORE As a general rule, removing headers is pretty useless. So another choice is to just close your eyes. -- Noel Jones
