+MASTER(8)                                                            MASTER(8)
+
+NAME
+       master - Postfix master process
+
+SYNOPSIS
+       master [-Dditvw] [-c config_dir] [-e exit_time]
+
+DESCRIPTION
+       The  master(8) daemon is the resident process that runs Postfix daemons
+       on demand: daemons to send or receive messages via the network, daemons
+       to  deliver  mail locally, etc.  These daemons are created on demand up
+       to a configurable maximum number per service.
+
+       Postfix daemons terminate voluntarily, either after being  idle  for  a
+       configurable  amount  of  time, or after having serviced a configurable
+       number of requests. Exceptions to this rule are the resident queue man-
+       ager,  address  verification  server,  and  the  TLS  session cache and
+       pseudo-random number server.
+
+       The behavior of the master(8) daemon is  controlled  by  the  master.cf
+       configuration file, as described in master(5).
+
+       Options:
+
+       -c config_dir
+              Read  the main.cf and master.cf configuration files in the named
+              directory instead of the default configuration directory.   This
+              also  overrides the configuration files for other Postfix daemon
+              processes.
+
+       -D     After initialization, run a debugger on the master process.  The
+              debugging  command is specified with the debugger_command in the
+              main.cf global configuration file.
+
+       -d     Do not redirect stdin, stdout or stderr to /dev/null, and do not
+              discard  the  controlling terminal. This must be used for debug-
+              ging only.
+
+       -e exit_time
+              Terminate the master process after exit_time seconds. Child pro-
+              cesses terminate at their convenience.
+
+       -i     Enable  init  mode:  do  not  become  a session or process group
+              leader; and similar to -s, do not redirect stdout to  /dev/null,
+              so  that  "maillog_file  =  /dev/stdout"  works.   This  mode is
+              allowed only if the process ID equals 1.
+
+              This feature is available in Postfix 3.3 and later.
+
+       -s     Do not redirect stdout to /dev/null,  so  that  "maillog_file  =
+              /dev/stdout" works.
+
+              This feature is available in Postfix 3.4 and later.
+
+       -t     Test  mode.  Return  a zero exit status when the master.pid lock
+              file does not exist or when that file is not  locked.   This  is
+              evidence that the master(8) daemon is not running.
+
+       -v     Enable  verbose  logging  for debugging purposes. This option is
+              passed on to child processes. Multiple -v options make the soft-
+              ware increasingly verbose.
+
+       -w     Wait in a dummy foreground process, while the real master daemon
+              initializes in  a  background  process.   The  dummy  foreground
+              process  returns  a  zero  exit status only if the master daemon
+              initialization is successful, and if it completes in  a  reason-
+              able amount of time.
+
+              This feature is available in Postfix 2.10 and later.
+
+       Signals:
+
+       SIGHUP Upon receipt of a HUP signal (e.g., after "postfix reload"), the
+              master process re-reads its configuration files.  If  a  service
+              has  been removed from the master.cf file, its running processes
+              are terminated immediately.  Otherwise,  running  processes  are
+              allowed  to  terminate as soon as is convenient, so that changes
+              in configuration settings affect only new service requests.
+
+       SIGTERM
+              Upon receipt of a TERM signal (e.g., after "postfix abort"), the
+              master  process  passes the signal on to its child processes and
+              terminates.  This is useful for an emergency shutdown.  Normally
+              one  would  terminate only the master ("postfix stop") and allow
+              running processes to finish what they are doing.
+
+DIAGNOSTICS
+       Problems are reported to syslogd(8) or postlogd(8).  The exit status is
+       non-zero  in case of problems, including problems while initializing as
+       a master daemon process in the background.
+
+ENVIRONMENT
+       MAIL_DEBUG
+              After initialization, start a debugger  as  specified  with  the
+              debugger_command configuration parameter in the main.cf configu-
+              ration file.
+
+       MAIL_CONFIG
+              Directory with Postfix configuration files.
+
+CONFIGURATION PARAMETERS
+       Unlike most Postfix daemon processes, the  master(8)  server  does  not
+       automatically  pick  up  changes  to  main.cf. Changes to master.cf are
+       never picked up automatically.  Use the "postfix reload" command  after
+       a configuration change.
