If you concatenate filters, then each filter must propagate any successor's reject status to its predecessor. As documented in: http://www.postfix.org/pipe.8.html http://www.postfix.org/FILTER-README.html The "hold" response is not documented, therefore it is not supported. > When one has just one content filter I know that it's enough to print the > command using some sprintf-like function, but I don't know how to do it > when there are many chained content filters. Is that a question about UNIX command pipes? Wietse
