This text pre-dates Milter support, and not every feature or documentation has been updated when Milter support was added. On second consideration, Postfix does run remote mail through Milters, so the -G flag probably does not affect Milters. So this would be a gap in coverage, in the sense that not all receive_override_options have a Postfix sendmail command-line equivalent. Wietse
