These programs still log earlier events 23 to the syslog service. 24 25 If Postfix is down, the non-daemon programs <a href="postfix.1.html"><b>postfix</b>(1)</a>, <a href="postsuper.1.html"><b>postsuper</b>(1)</a>, 26 <a href="postmulti.1.html"><b>postmulti</b>(1)</a>, and <a href="postlog.1.html"><b>postlog</b>(1)</a>, will log directly to <b>$<a href="postconf.5.html#maillog_file">maillog_file</a></b>. These 27 programs expect to run with root privileges, for example during Postfix 28 start-up, reload, or shutdown. 29 30 Other non-daemon Postfix programs will never write directly to <b>$<a href="postconf.5.html#maillog_file">mail</a>-</b> 31 <b><a href="postconf.5.html#maillog_file">log_file</a></b> (also, logging to stdout would interfere with the operation of 32 some of these programs). These programs can log to <a href="postlogd.8.html"><b>postlogd</b>(8)</a> if they 33 are run by the super-user, or if their executable file has set-gid per- 34 mission. Do not set this permission on programs other than <a href="postdrop.1.html"><b>postdrop</b>(1)</a>, 35 <a href="postqueue.1.html"><b>postqueue</b>(1)</a> and (Postfix >= 3.7) <a href="postlog.1.html"><b>postlog</b>(1)</a>. 36 37<b>CONFIGURATION PARAMETERS</b> 38 Changes to <a href="postconf.5.html"><b>main.cf</b></a> are picked up automatically, as <a href="postlogd.8.html"><b>postlogd</b>(8)</a> pro- 39 cesses run for only a limited amount of time. Use the command "<b>postfix</b> 40 <b>reload</b>" to speed up a change. 41 42 The text below provides only a parameter summary.
