To submit mail, +/* use the Postfix \fBsendmail\fR(1) command. +/* +/* The \fBpostfix\fR(1) command controls the operation of the Postfix +/* mail system: start or stop the \fBmaster\fR(8) daemon, do a health +/* check, and other maintenance. +/* +/* By default, the \fBpostfix\fR(1) command sets up a standardized +/* environment and runs the \fBpostfix-script\fR shell script +/* to do the actual work. +/* +/* However, when support for multiple Postfix instances is +/* configured, \fBpostfix\fR(1) executes the command specified +/* with the \fBmulti_instance_wrapper\fR configuration parameter. +/* This command will execute the \fIcommand\fR for each +/* applicable Postfix instance. +/* +/* The following commands are implemented: +/* .IP \fBcheck\fR +/* Warn about bad directory/file ownership or permissions, +/* and create missing directories. +/* .IP \fBstart\fR +/* Start the Postfix mail system. This also runs the configuration +/* check described above. +/* .IP \fBstart-fg\fR +/* Like \fBstart\fR, but keep the \fBmaster\fR(8) daemon running +/* in the foreground, and enable \fBmaster\fR(8) "init" mode +/* when running as PID 1. +/* This command requires that multi-instance support is +/* disabled (i.e. the multi_instance_directories parameter +/* value must be empty). +/* +/* When running Postfix inside a container, see MAILLOG_README +/* for logging to stdout. Postfix logs to syslog by default, +/* which requires a) running a syslogd process inside the +/* container, or b) mounting the container host's /dev/log +/* socket inside the container (example: "docker run -v +/* /dev/log:/dev/log ..."), and c) a distinct Postfix "syslog_name" +/* prefix that identifies logging from the Postfix instance. +/* .IP \fBstop\fR +/* Stop the Postfix mail system in an orderly fashion. If +/* possible, running processes are allowed to terminate at +/* their earliest convenience. +/* .sp +/* Note: in order to refresh the Postfix mail system after a +/* configuration change, do not use the \fBstart\fR and \fBstop\fR +/* commands in succession.
