As documented in the pipe(8) manpage: In the case of a NON-ZERO EXIT STATUS, a limited amount of command out- put is logged, and reported in a delivery status notification. When the output begins with a 4.X.X or 5.X.X enhanced status code, the sta- tus code takes precedence over the NON-ZERO EXIT STATUS (Postfix ver- sion 2.3 and later). As noted by Viktor, use "postfix reload" to make the running behavior consistent with Postfix configuration files. Wietse
