• If the command exits with a non-zero return code, the delivery is deemed to have failed, unless either the ignore_status option is set (in which case the return code is treated as zero), or the return code is one of those listed in the temp_errors option, which are interpreted as meaning “try again later”. In this case, delivery is deferred. Details of a permanent failure are logged, but are not included in the bounce message, which merely contains “local delivery failed”.
  
  The return_output option can affect the result of a pipe delivery. If it is set and the command produces any output on its standard output or standard error streams, the command is considered to have failed, even if it gave a zero return code or if ignore_status is set. The output from the command is included as part of the bounce message. The return_fail_output option is similar, except that output is returned only when the command exits with a failure return code, that is, a value other than zero or a code that matches temp_errors.
  
  return_fail_output Use: pipe Type: boolean Default: false
  If this option is true, and the command produced any output and ended with a return code other than zero or one of the codes listed in temp_errors (that is, the delivery failed), the output is returned in the bounce message. However, if the message has a null sender (that is, it is itself a bounce message), output from the command is discarded. This option and return_output are mutually exclusive. Only one of them may be set.
