            "content": "Non-daemon  Postfix  programs don't know that they should log to the internal logging service\nbefore they have processed command-line options and main.cf parameters. These programs  still\nlog earlier events to the syslog service.\n\nIf Postfix is down, the non-daemon programs postfix(1), postsuper(1), postmulti(1), and post‐\nlog(1),  will  log  directly  to $maillogfile. These programs expect to run with root privi‐\nleges, for example during Postfix start-up, reload, or shutdown.\n\nOther non-daemon Postfix programs will never write directly to $maillogfile  (also,  logging\nto  stdout  would interfere with the operation of some of these programs). These programs can\nlog to postlogd(8) if they are run by the super-user, or if their executable file has set-gid\npermission. Do not set this permission on programs other than postdrop(1),  postqueue(1)  and\n(Postfix >= 3.7) postlog(1).\n",
